Warm sake by standing the filled tokkuri in a pan of hot — not boiling — water for a few minutes until it reaches about 40–50°C, judging by touch. Gentle water heating keeps the flavour balanced, boiling makes it harsh, and a microwave works in a pinch if you stir it so it heats evenly.
Recommended Stand the tokkuri in hot (not boiling) water to about 40–50°C — gentle heat, never a hard boil — Warm sake (kan) is heated gently in a water bath, which warms it evenly without driving off the aroma. Pour the sake into a tokkuri (the ceramic flask) and stand it in a pan or deep bowl of hot water that comes about two-thirds up the flask; take the pan off the heat or keep it at a bare simmer, not a rolling boil. Leave it two or three minutes, then test the temperature by touching the flask or a drop on your wrist. There are named stages worth aiming for: nurukan, gently warm at around 40°C, and atsukan, hot at around 50°C; much hotter and the alcohol turns sharp and the flavour flattens. Warming suits robust styles like junmai best, while delicate ginjo and daiginjo are usually better chilled, since heat can blow off their fine aromas. A microwave will do at a push — heat a filled tokkuri in short bursts — but it heats unevenly, so stir or swirl it and check, since the neck often gets too hot while the base stays cool. Serve warm sake straight away in small cups (ochoko), as it cools quickly.
