The team from Toyonoume used the Cosmos Deep Sea Yeast to create this unique sake. The yeast had to survive several months at depths of 6,200 metres, with a 1 in 300 million chance of survival. Toyonoume are one of the first sake makers to create sake with this yeast.

This sake has a melon and banana aroma with a dry and underlying sweetness. It's food friendly and it goes particularly well with meat dishes like Yakitori and Karaage.
