Ice Breaker “Summer” Sake 玉川アイスブレイカー酒

Some days ago when we did our usual take-out sashimi and sushi from Tako Grill, I spotted a sake called “Ice Breaker”. I immediately recognized the distinct blue label with the penguins on it. This is the sake we had at Kyoto Izakaya “Kura-Kura” 蔵倉 in 2015. At that time, this is what we posted:

“ Although I never tasted this sake, I remember reading about it on the Internet. I remember reading that it was brewed by the first and only foreigner (British) sake master Philp Harper at Kinoshita Shuzou 玉川木下酒造 in Kyoto. Seeing the distinctive blue label with the Penguin on it, I had to taste this one as the next sake. The sommelier/wife (?) commented "Oh, you like summer sake". This is junmai ginjou genshu, non-filtered 純米吟醸無濾過生原酒 made from Nihonbare 日本晴 sake rice. I think this was a new sake just released. We tried it first like regular cold sake. It was OK but not great. Then I remembered that the idea behind this sake is that it can be drunk on the rocks which would be particularly refreshing in the hot Kyoto summer. Since it is genshu (not diluted and of high alcohol content), it would withstand the ice. (And how could anyone be hot after seeing that label?) My wife provided some ice cubes from her oolong tea to test my theory. We thought it actually tasted much better so we requested more ice and drank it frosty cold. This was a rather clean sake and we did not notice the high alcohol.”

Since the weather was getting a bit warmer I decided the time had come to open the bottle. Out of curiosity I went to the Japanese Tamagawa brewery web site which interestingly is in English (which makes sense given the brew master is British). I noticed several differences between the description on the web site and the bottle I had in the refridgerator. According to the website the sake is available in both the 500 ML and the usual 1.6L size (1 shou-bin 一升瓶) bottles in Japan. As far as I know, only the 500ml size is available in the U.S. which is a rather unusual size (usual size is 720ml). In addition, while the sake in the fridge and described on the web site were both summer sakes; available between May and August, the brew years were different. The brew year for the sake sold in Japan was advertised as 2023 which means it was brewed from the winter of 2023 to spring 2024 making it a newly released sake. In contrast, the brew year for the bottle we had was listed as 2022 meaning it was brewed from winter 2022 to spring 2023 making it one year older than the ones advertised on the Japanese web site (see addendum below).  I do not know how this sake was aged; whether cold aged like “Hiyaoroshi” ひやおろし or room temperature aged. However it was aged, when we opened the year old bottle, the sake was clear and very fresh tasting (Not like “ko-shu” 古酒 which can be darker colored and funky tasting). We had it first chilled and then on-the-rocks. Chilled it tasted dry but not bone dry. It had nice assertive flavors but was not yeasty or too fruity. On-the-rocks, many of the assertive forward flavors became muted but interestingly more flavors appeared to emerge making the overall flavor much more complex. This characteristic moved this sake straight to the top of our list of favorite sakes. This is the sake we will serve for those “special occasions” which require something extra. Ice cold sake is perfect for hot humid summer (we have our share of those kind of days in Washington DC area but nothing comparable to a Kyoto summer.) In any case, we really enjoyed this sake.

The night we tasted the sake we had a small amount of toro トロ and tai 鯛 (sea bream) sashimi. I also served Russian marinate salmon ロシア漬け and salmon kelp roll 鮭の昆布巻き along with pickled daikon, cucumber and blanched sugar snap.

The next time, I went to Tako Grill, this sake was not available any longer. It was available from our trusty “Tippsy sake” so we ordered a few bottles for coming summer.

Addendum: While I was looking at Japanese food blogs, I came across the description and picture of “Ice Breaker” sake. The picture clearly shows “2022BY” in the label (the blog post is dated as “5/18/2024). So, it is likely that all Ice Breaker sake, either in Japan and US, available this year is “2022BY”. One year aging may be attributable for the flavors of this sake.
