In just four years, bottle-fermented sparkling sake (Awasake) has emerged as an exciting new category in Japanese sake. The Awasake producer association has a shared quality charter, technical patent, and promotional campaign. Awasake must be made to sparkle by a second fermentation, and not (as in the more mass-market style of sparkling sake) by carbonation. The development of the technique to make bottle-fermented sparkling sake was led by Mr. Noriyoshi Nagai, of Nagai Sake in Gunma. Mr. Nagai first started experimenting with bottle-fermented sparkling sake in 2003. “I failed 700 times”, he smiles, “before I succeeded in 2008.” He went on to share his method (bear in mind that a conventional ‘tirage’ is not permissable under Sake rules) with other sake producers, who went on to make their own increasingly impressive bottle fermented sparkling sake. In 2016, nine sake breweries came together to create the Awasake Association. Today there are fifteen members, from all over Japan.

The styles and quality of Awasake are (as you would expect in such a young category) highly diverse, from delicate Brut Nature with ethereal ginjo character, to full-bodied, rich demi-sec examples. Some are delicate and floral – and almost on the same planet as the experience of drinking a sparkling wine. Others are from a different universe: savoury, heavily golden, and almost hefty, with vigorous toasted cereal character.

This is a truly intriguing new category. More aromatic than their vinous equivalents, with lower acidity but higher umami and (in some cases) extract, Awasake offers a fascinating new option for fine bubbles. Noriyoshi was inspired by his love of Champagne to develop Awasake. Cultured, friendly, well-travelled and curious, he has both visited and hosted acclaimed European winemakers.

The presentation of Awasake, in classic sparkling wine bottles, recalls that of Champagne. But the labels, paper and graphic design are beautiful and distinctively Japanese. And the style and flavour profile is a different creature. While carbonated sparkling sake – typically with very low alcohol, high sugar and floral easiness – is readily found in Japanese restaurants in the UK, Awasake is a different proposition. These bottle fermented sake are still rare here, although their reputation in Japan (one of the world’s biggest consumers of Champagne) is high, and admired as a creative food-pairing option. Many of the rich, dark styles made me wish for a deeply creamy, deeply smelly cheese to accompany. Noriyoshi smiles, and tells me that this is one of their favourite pairings.

Japanese culture delights and entrances through this paradox: diligent dedication to both its own heritage, and creative interpretations of others.

Below are my tasting notes from a fascinating tasting of Awasake from across Japan. I really liked them, once I’d got my head around the very different structure and texture to any bottle-fermented sparkling wine in my frame of reference. And I was greatly impressed and moved by the incredible achievement of these producers who have come together to create this new, premium, technically demanding drink with great unity and focus. Noriyoshi-san’s “700 failures” were just 700 steps to a new creation.
