Electric Sake Warmer 電気酒燗器

We usually drink sake cold. For drinking sake cold, we like a crisp, clean, and fruity flavor profile of daiginjo 大吟醸. Some junmai 純米 and junmai ginjo 純米吟醸 sakes also have this flavor profile. Our house sake, curretly, is “Tengumai 50 Junmai Daiginjo” 天狗舞純米大吟醸. We enjoy it cold and it has a nice clean, dry,  crisp, and fruity flavor. Now, not going into the details, somehow, by mistake (not mine), we ended up with a case of “Tengumai yamahai-shikomi junmai”天狗舞山廃仕込純米 instead of our favored house sake.  As I mentioned previously this sake has a more savory, yeasty and mushroomy flavor when tasted cold or at room temperature. Then I read that this sake changes its flavor profile if heated. Almost in desperation, we tried it warm (at 120F or “Atsu-kan” 熱燗). We were pleasantly surprised that the flavor profile changed completely and became smooth and mild. We thought “Ah-Ha” the secret is that this sake should be consumed warm which would be particularly appropriate during the winter months when we have dishes like hot pot “nabe” 鍋 dishes, “sukiyaki“ すき焼き, or  “oden” おでん. But the main reason we rarely drink sake warm is that one additional step of warming it up and the difficulty of maintaining the temperature while enjoying it warm.  So, we decided to splurge on an electric sake warmer 電気酒燗器.

We bought it at Amazon but it came from a seller in Japan. The sake warmer sits on top of the heating unit. The server holds about 240ml (1号半). It heats up to the specified temperature in10-15 minutes. The temperature control is continuous (not discreet steps) and ranges from about 35C to 60C (95F to 140F). Using my digital thermometer and water, the actual temperatures are higher (by about 5-10F) than it indicated. We usually like “Atsu- kan” *.

*ranges of warm sake temperature
“Jouon” 常温, room temperature 20℃ (68F)
”Hinata kan” 日向燗 sunny side 30℃ (86F)
”Hitohada kan” 人肌燗 skin temperature 35℃ (95F)
”Nuru kan” ぬる燗 luke warm 40℃ (104F)
”Jou kan” 上燗 warm 45℃ (113F)
”Atsu kan” 熱燗 hot 50℃ (122F)

The sake warmer works extremely well. We can have it sitting next to us and as we are enjoying the warm sake, we can add more sake to the server. By the time we are ready for the next serving, the sake has reached the proper temperature. The only challenge is to warm up enough but not too much sake and to consume it at just the peak of time it has been warming. This is because any leftover sake once heated will not be good the next day for example. Also,warming up the sake and keeping it warm more than 1 hour is not good either. In any case, this was a great improvement break through.  We are glad that we can now enjoy Tengumai junmai sake this way. So the mistake which had us end up with a case of tengumai-junmai instead of our favored house sake was indeed a “blessing in disguise”. It introduced us to a sake variation which we now enjoy but would never otherwise thought of trying.
