Two distinctive Japanese white wines I have enjoyed: Edel Wein Riesling Lion 2021 from Iwate and CAVE HATANO Chardonnay & Sauvignon Blanc 2023 from Nagano’s Chikumagawa Wine Valley.
Japanese white wine includes familiar grapes such as Chardonnay and Riesling alongside distinctive Japanese varieties and crosses that are rarely seen overseas.
Japanese white wine is often introduced through Koshu, and for good reason. Koshu is Japan’s signature white grape and an important part of the country’s wine story. But after years of visiting wineries and tasting wines around Japan, I have found that the white-wine picture is much broader than many visitors expect.
Alongside Koshu, I have tasted Japanese Chardonnay, Riesling, Pinot Gris, Sauvignon Blanc, Kerner and Pinot Blanc, as well as locally developed or distinctive grapes such as Shinano Riesling, Ryugan, Kai Blanc, Riesling Lion and Yama Blanc. I have also tried wines made from grapes better known in Japan as table grapes, including Delaware, Niagara and Shine Muscat.
What interests me most is the range. Some are crisp and dry, others carry a softer sweetness or more obvious fruit, and even wines made from the same grape can be very different. Japanese white wine is not one style, and that diversity is what makes it interesting to explore.
What Japanese White Wine Can Be Like
I would be careful about giving Japanese white wine one fixed tasting profile. Grapes are grown in very different conditions from Yamanashi and Nagano to Hokkaido, Yamagata, Akita and Iwate, and wineries work with both international varieties and grapes that are rarely seen outside Japan.
In my own tastings, freshness and good acidity come up often, but the wines can range from delicate and mineral to softly sweet, citrus-driven, floral or quite tropical. The grape, vineyard and producer matter more than any single idea of what a Japanese white wine should taste like.
Koshu Is the Starting Point, Not the Whole Story
Koshu is still the natural starting point. I taste it regularly in Yamanashi and tend to prefer cleaner stainless-steel examples because I like being able to taste the grape and vineyard clearly. I often find citrus, green apple, minerality and good acidity, although Koshu can be made in many different styles.
I cover its origins, winemaking and different expressions separately in the Koshu Wine Guide. I also explore sparkling Koshu in depth below, including production methods, Yamanashi producers and my own tasting experiences.
Here, Koshu is useful as a reference point. Once you move beyond it, Japanese white wine becomes much more diverse.
Japanese Chardonnay: One of the Whites That Changed My Mind
I have never been especially drawn to heavy, buttery Chardonnay. That is one reason Japanese Chardonnay has been interesting for me. Many of the examples I encounter are brighter and lighter, with enough freshness to make the grape feel more inviting.
I have tasted Chardonnay from Manns, Estate Chardonnay from Haramo Winery, and Chardonnay from Sakaori, among others. They are not identical wines, and I would not force them into one flavor description. More generally, I often find Japanese Chardonnay less heavy than the richer styles I had associated with the grape in the past.
A particularly good example of how Chardonnay can work in Japan was CAVE HATANO Chardonnay & Sauvignon Blanc 2023 from the Chikumagawa Wine Valley in Nagano. I thought it was an excellent, high-quality blend. What I liked was how it brought together qualities I enjoy in both grapes: the recognizable character of Chardonnay with the drier, fresher side of Sauvignon Blanc. Neither grape seemed to overpower the other.
For me, wines like this show why Chardonnay deserves a substantial place in a Japanese white-wine guide. Koshu may be the signature Japanese grape, but Chardonnay and Chardonnay-based wines can express a very different side of modern Japanese winemaking.
Riesling, Shinano Riesling and Riesling Lion
Riesling and Riesling-related varieties have given me some of my favorite softer white wines in Japan.
Manns Shinano Riesling is one I particularly enjoy. It is not too sweet. The sweetness is softer and more delicate, which is exactly the kind of balance I like in Riesling.
I have also enjoyed Château Mercian Omori Riesling from Akita. My memory of that wine is citrus with a mild sweetness. It is a different expression from Shinano Riesling, but both show that some sweetness can work very well when the wine remains fresh and balanced.
Riesling Lion is a particularly Japanese part of this story. It is a cross between Riesling and Koshu Sanjaku and is strongly associated with northern Japan. I have tasted Riesling Lion from Asahimachi Wine, including Forte and Lion Riesling, and I have also tasted Edel Wein Satsukinagane Riesling Lion 2021.
The Edel Wein 2021 was an excellent example of the grape. I remember the sweetness as well balanced rather than heavy, with a soft, smooth character and a refreshing finish. That 2021 vintage also received a Gold award at the Sakura Awards 2023.
Riesling Lion is one of the varieties that makes Japanese white wine more interesting to me because it is not simply another international grape planted in Japan. It has developed its own place in regions such as Iwate, where producers have worked with it for many years.
Pinot Gris Can Show Very Different Sides in Japan
Pinot Gris has given me two clear examples of how different Japanese wines from the same grape can be.
A 2021 Pinot Gris from COCO FARM & WINERY had pear and white peach, with soft fruitiness, noticeable acidity and a very good balance between the fruit and freshness.
Yamazaki Winery Pinot Gris left a very different impression. I found it more tropical, with a fruit character that reminded me of mango.
For me, those two wines are a good reminder of how much variation there can be in Japanese white wine. Even with the same grape, different vineyards and winemaking choices can produce very different expressions. It is one reason I avoid giving Japanese white wine a single tasting profile—the range is much broader than that.
Sauvignon Blanc, Kerner and Other International Whites
Sauvignon Blanc is another international grape that can work very well in Japan. I have enjoyed Sauvignon Blanc from Villa d’Est in Nagano, while a Manns Nagano Sauvignon Blanc stands out in my memory as exceptional.
Kerner is another white I have enjoyed. The example I remember was light in a way that reminded me slightly of Koshu, but clearly different: lemon, green apple and pear, with a mineral character and decent acidity. I am leaving the producer unnamed because I am not completely certain which bottle it was, and I would rather be accurate than attach the memory to the wrong winery.
I have also tasted Pinot Blanc from Takahata Winery and Petit Manseng as part of a blend at Sanyo Winery. Japan also produces wines from varieties such as Riesling, Sauvignon Blanc, Semillon and Pinot Gris in several regions.
These grapes do not need to taste exactly like their European counterparts to be interesting. What matters to me is whether the wine feels balanced and whether the producer has made something that suits the grape and the place.
Japanese-Developed and Lesser-Known White Grapes
Some of the most interesting names in Japanese white wine are grapes that many overseas visitors have never heard of.
I have tasted Kai Blanc from Haramo Winery, along with varieties and crosses such as Chardonnay de Corail, Shinano Riesling and Riesling Lion. These wines add another layer to the category because they are not simply familiar international grapes grown in Japan.
Ryugan is particularly interesting because of its versatility. I have tasted Ryugan from Goichi Wine and remember enjoying it. The grape can be made as a still white wine, used for sparkling wine, and even distilled into brandy. Manns took it in a very different direction with its SOLARIS Brandy “Ryugan” 1989, made from Ryugan grapes harvested in 1989, double-distilled and matured in oak.
The brandy is not a white wine, but it is a useful example of how differently one grape can be expressed.
Another unusual wine I have tasted is Yama Blanc from Totto Wine, made using Yama Budo and Pinot Noir. Yama Blanc has an aroma reminiscent of green apples and a tropical fruit character, but it is not sweet. The finish is crisp, clean and refreshing.
Table Grapes Can Also Become Japanese Wine
Japan has a strong table-grape culture, and some grapes better known as fruit are also used for wine.
Delaware and Niagara have both been used for Japanese wine, and I have also tasted Shine Muscat wine from Sanyo Winery. Shine Muscat is much better known in Japan as a premium table grape, which makes seeing it used in wine particularly interesting.
I would not put these grapes in exactly the same category as Chardonnay, Riesling or Koshu. Their role is different. But they help show how broad the Japanese approach to grapes can be, especially when producers experiment with fruit that already has a strong place in Japanese agriculture.
Koshu Sparkling Wine: Yamanashi Producers, Methods and My Tasting Notes

Koshu sparkling wine at MGVs and Aruga Branca, including Brilhante served in Riedel Koshu glasses overlooking the Katsunuma vineyards.
Koshu sparkling wine is one of Yamanashi’s most distinctive wine styles. Made wholly or partly from Japan’s Koshu grape, it combines the variety’s natural freshness with bubbles that can range from lively and fruit-driven to fine, dry and complex.
Quick answer: Koshu sparkling wine is Japanese sparkling wine made with Koshu grapes, usually from Yamanashi. Its bright acidity, restrained fruit and citrus character make it especially well suited to sparkling wine, but the bottles are not all made in the same way. Some use secondary fermentation in the bottle, others use the Charmat or tank method, and some releases use carbonation.
I have lived and guided wine tours in Yamanashi’s Koshu Valley for more than a decade. Koshu sparkling is one of the wines that most consistently surprises my guests. Many arrive knowing Japanese whisky or sake but have never tasted a serious Japanese sparkling wine. A well-made Koshu sparkling often changes that perception in the first glass.
Why Koshu Works So Well as a Sparkling Wine
Koshu is a late-ripening, pale pink-skinned grape associated above all with Yamanashi. It usually produces a lightly colored wine with fresh acidity, subtle fruit and a clean finish. Those qualities give a winemaker a strong base for sparkling wine.
The bubbles lift Koshu’s delicate aromas rather than overpowering them. Citrus, grapefruit, green apple and gentle floral notes are common impressions, while some wines show a mineral or slightly savory edge. The grape’s natural freshness also helps the wine remain lively when served cold, which is one reason Koshu sparkling is especially enjoyable during Yamanashi’s hot summers.
Koshu sparkling should not be treated as one fixed style or as a simple Japanese copy of Cava or Prosecco. The result depends on the vineyard, grape composition, harvest timing, fermentation method, dosage, lees aging and the producer’s own approach. Some bottles are immediate and fruit-focused; others are structured, dry and capable of developing more complexity.
Three Main Ways Koshu Sparkling Wine Is Made
Traditional Bottle Fermentation
With the traditional method, the second fermentation takes place inside the bottle. The wine may then remain in contact with the lees before riddling and disgorgement. This approach can produce finer, more integrated bubbles and can add texture, depth and subtle yeasty or bready notes.
Charmat or Tank Fermentation
With the Charmat method, the second fermentation takes place in a sealed pressure tank. This often preserves more of Koshu’s fresh grape, citrus and orchard-fruit character. It can produce a clean, lively sparkling wine that works well as an aperitif or with a meal.
Carbonation
Some sparkling wines are made by adding carbon dioxide to a finished still wine. This can create a direct, refreshing style, but it should not be confused with bottle or tank secondary fermentation. The method should be checked for each bottle rather than assumed from the words “Koshu sparkling.”
Eight Yamanashi Producers to Know
These are not presented as a ranking. They show how differently Yamanashi producers interpret Koshu and Japanese sparkling wine. Specific vintages, tasting availability and sales can change, so visitors should not plan around one bottle without checking first.
Koshu Sparkling Traditional Brut
Koshu Sparkling Traditional Brut from 100% Koshu using secondary fermentation in the bottle. It is a dry, traditional-method expression that keeps the grape itself at the center of the wine. This is one of my personal favorites because the wine is precise and refreshing without losing Koshu’s quiet fruit character.
Grace Serena Extra Brut
Grace Wine’s Serena Extra Brut is an important comparison because it is not made from Koshu alone. It combines Koshu and Chardonnay from Yamanashi, undergoes secondary fermentation in the bottle and receives extended bottle aging. The current 2020 release was aged for 48 months before disgorgement. The result is a very dry, carefully made Japanese sparkling wine with greater depth and creaminess than many lighter Koshu-only styles.
Grace is another of my favorites. It shows how Koshu can contribute freshness and regional identity while Chardonnay adds body and structure. Serena Extra Brut is also difficult to obtain. In my experience it is frequently sold out, so finding it available by the bottle or as a tasting is a special opportunity rather than something visitors should expect.
Katsunuma Jyozo Aruga Branca Brilhante
Katsunuma Jyozo is the winery; Aruga Branca is its Koshu-focused brand. Aruga Branca Brilhante is a dry, bottle-fermented sparkling wine made from Koshu. It has long been one of the Yamanashi sparkling wines I most enjoy introducing to guests.
When Katsunuma Jyozo is one of the final stops, guests sometimes have the chance to taste Aruga Branca Brilhante in a Riedel Champagne Wine Glass/Koshu. Compared with an extremely narrow flute, the bowl gives the wine more room to show its citrus aroma, texture and fine bubbles. Guests are often pleasantly surprised by how refined and complete a Japanese sparkling wine can be when it is well chilled and served in the appropriate glass.
The winery also sells Riedel Koshu glasses, subject to availability. The local story I have been told is that Mr. Aruga and Mr. Riedel were long-time friends, and that their relationship helped begin the collaboration around a glass suited to Koshu. Riedel later released a Koshu-specific glass selected together with Japanese Koshu producers. This connection between producer, grape and glass is part of what makes a Brilhante tasting at the winery memorable.
Yozo Vineyards NOA Koshu Sparkling Extra Brut
Another excellent example is NOA Koshu Sparkling Extra Brut from Yozo Vineyards in Kofu. It is made entirely from Koshu grown in the winery’s own Yamanashi vineyard. Low-temperature fermentation is used to draw out the grape’s fruit and acidity, and the wine is finished Extra Brut, giving it a clean, dry profile with bright citrus character.
NOA is a useful addition to this guide because it shows the freshness and precision that Koshu can achieve in a modern Yamanashi sparkling wine. I find it especially appealing as an aperitif and with delicate Japanese food, seafood, salads and vegetable dishes. The winery does not state the secondary-fermentation method in its current public description, so it should be appreciated for its taste and balance without assuming how the bubbles were produced.
MGVs K537 GI Yamanashi N.V. POSH
MGVs approaches winemaking in a highly systematic way, and its product codes explain the grape, origin, juice preparation and production method. In K537, “K” identifies Koshu, “5” indicates GI Yamanashi, “3” refers to a combination of free-run and pressed juice, and “7” identifies secondary fermentation in tank.
K537 is made from 100% Koshu using the Charmat method. It is dry, smooth and refreshing, with the citrus-led character of the grape kept clear. MGVs also produces bottle-fermented POSH wines, making the winery particularly useful for comparing how production method changes the same grape. I consider MGVs an excellent producer and a strong introduction to modern Koshu sparkling.
At the winery, K537 is displayed with medals from the Texas International Wine Competition, including a 2023 Gold ribbon. It also received Gold at the Berliner Wine Trophy 2023. Awards are not the reason I recommend a wine, but they show that this modern Yamanashi sparkling has earned recognition well beyond the region.
Manns Wine Kobo no Awa Koshu
Manns Wine produces one of Yamanashi’s broadest and most approachable ranges of sparkling wines from Japanese grape varieties. Koshu is central to its Kobo no Awa series, which includes a standard Koshu, a dry Koshu Brut and a softer Demi-Sec style.
The wines use the Charmat method, with secondary fermentation in pressure tanks. Manns chose this method to retain the grape’s fresh aroma and delicate character. The Koshu Brut is crisp and dry, while the wider range allows drinkers to compare different sweetness levels without leaving the same grape family.
Sasaichi OLIFANT Koshu Bottle-Fermented Sparkling
Sasaichi Shuzo is best known as a Yamanashi sake brewery with more than 350 years of history, but its OLIFANT wine brand dates to 1953. OLIFANT Koshu Bottle-Fermented Sparkling brings the brewery’s fermentation experience together with Yamanashi’s wine tradition and uses secondary fermentation in the bottle.
The wine received Gold in the sparkling category at the Sakura Awards 2023. It is a useful traditional-method comparison with the Charmat-method Koshu wines from MGVs and Manns, and another example of how differently producers can interpret the same Yamanashi grape.
Kisvin Koshu Sparkling
Kisvin produces Koshu sparkling in limited releases. Recent winery descriptions have emphasized pear and citrus aromas, delicate bubbles and umami. Availability can be irregular, and some vintages sell out or are not released, so it is better treated as a wine to discover when available rather than a guaranteed winery tasting.
Kisvin adds another useful perspective to the category: Koshu sparkling can be serious and carefully made without needing to imitate a European regional style.
Beyond Koshu: Haramo Black Queen Sparkling Red
Haramo Black Queen Sparkling Red is not a Koshu wine, so it sits outside the main list above. It is included because it shows the wider range of sparkling wine being made in Yamanashi. Haramo describes it as the winery’s first sparkling wine, made from 2023 Yamanashi-grown Black Queen and finished as a refreshing red sparkling style.
In my experience, this is a rare bottle with limited and unpredictable availability. Visitors should not expect it to be open for tasting, but finding it provides an unusual chance to compare the pale, citrus-led character of Koshu sparkling with a fruitier Japanese red sparkling wine.
Morey’s Tasting Note
In my experience, Koshu sparkling wine is fruity but dry, with bright acidity and a clean mineral character. I often notice citrus and grapefruit, with a slight green-apple flavor. The best examples are well balanced, allowing the differences between vineyards and each winery’s approach to come through.
The exact balance changes from bottle to bottle. A Charmat-method wine may emphasize fresh fruit and immediacy, while a traditional-method wine can show finer bubbles, more texture and greater depth. Koshu itself remains subtle, so careful winemaking is easier to notice than it might be in a strongly aromatic grape.
How to Serve Koshu Sparkling Wine
Koshu sparkling is usually best served well chilled. Fresher, fruit-driven bottles are particularly refreshing in warm weather, while more complex bottle-aged examples can be allowed to warm slightly in the glass so their texture and aroma become clearer.
A narrow flute will preserve the visual stream of bubbles, but a wine glass with a little more bowl space can reveal more aroma and texture. For a serious traditional-method Koshu sparkling, I prefer a glass that allows the wine to open rather than an extremely narrow flute.
Food Pairings
Koshu sparkling is excellent on its own, as an aperitif or at the start of a meal. Its acidity and restrained fruit also make it one of the easiest Japanese wines to pair with lighter food.
- Seafood, sashimi and sushi
- Salads and vegetable dishes
- Japanese grilled vegetables
- Tempura and lightly salted fried dishes
- Grilled fish or chicken seasoned simply with salt
- Carpaccio, caprese and other light appetizers
For me, seafood and salads are especially dependable pairings. The wine refreshes the palate without covering delicate ingredients, while the citrus and mineral qualities can echo lemon, salt and fresh vegetables.
How to Choose a Bottle
When comparing Koshu sparkling wines, check five things:
- Grape composition: Is it 100% Koshu, or is Koshu blended with Chardonnay or another grape?
- Production method: Was the second fermentation completed in the bottle or in a tank, or was the wine carbonated?
- Sweetness: Brut and Extra Brut are dry, while other cuvées may be softer or noticeably sweeter.
- Aging: Extended lees or bottle aging can add texture and complexity.
- Purpose: Decide whether you want a light summer aperitif, a food wine or a more complex bottle for a special meal.
Tasting Koshu Sparkling Wine in Yamanashi
Yamanashi wine country is the best place to compare Koshu sparkling at its source, but availability changes constantly. Limited bottles sell out, tasting menus change, and some wineries require reservations or do not open every wine each day.
That is why a useful winery day should be built around the best current opportunities rather than a rigid promise to visit a particular producer or taste one exact bottle. During a private Yamanashi wine tour from Tokyo, sparkling wine can be included when suitable wines and appointments are available.
All Winery Tours Japan experiences are personally guided by Morey, a Bilingual English-Speaking Local Guide who has lived in the Koshu Valley for more than a decade and has built long-standing relationships with winery owners, winemakers and residents throughout the valley.
Frequently Asked Questions
Is Koshu sparkling wine always made from 100% Koshu?
No. Many bottles are 100% Koshu, but some Japanese sparkling wines combine Koshu with Chardonnay or another grape. Grace Serena Extra Brut is a clear example of a Koshu and Chardonnay blend.
Is all Koshu sparkling wine made by the traditional method?
No. Yamanashi producers use bottle secondary fermentation, Charmat or tank fermentation, and carbonation. The production method should be checked for each wine.
Is Koshu sparkling wine dry?
Many well-known examples are dry, including Brut and Extra Brut wines, but sweeter and softer styles also exist. Manns Wine, for example, produces several Koshu sparkling styles with different sweetness levels.
What food goes with Koshu sparkling wine?
Seafood, sushi, sashimi, salads, tempura, grilled vegetables and lightly seasoned dishes are reliable choices. The best pairing depends on the wine’s dryness, weight and production method.
A Japanese Sparkling Wine Worth Discovering
Koshu sparkling wine deserves to be understood as a category of its own. It can be light and immediate or dry, fine-bubbled and complex. The strongest examples keep Koshu’s citrus, mineral and green-fruit character while showing the clear influence of vineyard, method and producer.
For visitors to Yamanashi, it is also one of the most enjoyable ways to understand how far Japanese wine has developed. A glass of well-chilled Koshu sparkling is refreshing at any time, but it is especially memorable in summer, served close to the vineyards and wineries where the grape is grown.
What I Have Learned from Tasting Japanese White Wine
The biggest lesson for me is that Japanese white wine is much more varied than simple descriptions often suggest.
Koshu can be crisp and mineral. Shinano Riesling can carry a delicate sweetness. Riesling Lion can be soft, balanced and refreshing. Pinot Gris can move from pear and white peach to almost tropical mango. Kerner can show lemon, green apple, pear and minerality. Yama Blanc can be tropical and fruity while still finishing crisp and clean. Chardonnay can feel lighter and brighter than the heavier styles many people associate with the grape, while a well-made Chardonnay–Sauvignon Blanc blend can bring together qualities of both.
That is why Japanese white wine becomes more interesting once you move beyond a single grape or a single tasting profile. There is a lot of experimentation here, but there is also a growing sense of which varieties and styles work well in different parts of Japan.
Where This Fits in the Wider Japanese Wine Story
This guide is about Japanese white wine as a national category, with particular attention to Chardonnay and the wider range of white grapes being used in Japan.
For a deeper look at Yamanashi’s red and white grape varieties, see Wines of Yamanashi. For a broader introduction to Japanese wine across both white and red styles, see my Japanese Wine Guide.
If you are visiting Yamanashi, the wines available at wineries change with the producer, vintage and season. On our private Yamanashi wine tour, I like showing guests that there is much more to Japanese wine than the bottle or grape they may already know.
For me, that discovery is still one of the most enjoyable parts of tasting Japanese white wine.
