When I sat down to write last week's Sake FAQs, I realized all the questions about serving Sake hot deserve their own, dedicated post. So let's dive in!
Is Hot Sake Bad?
No! Until a hundred years ago, most Sake was made to be served warm or hot. Statistically, hot Sake is still very popular, and the preference among Japanese women.
In America, restaurants usually serve cheaper Sake hot, but as long as you enjoy the flavor, don't let that knowledge stop you from enjoying it. If someone more experienced has intentionally selected a Sake to serve warm, you can definitely expect it to improve the flavor.
How Hot Should I Drink My Sake?
Heating a robust or full-bodied Sake can absolutely enhance rice-forward flavors, including Umami. There are several target temperatures, but the main two are "warm" and "hot", 40°C (104°F) or 50°C (123°F).
At 55°C (133°F) many flavors begin to evaporate out of Sake. To help you get a sense of that, my kitchen tap maxes out at 130°F, so if yours is like mine, try letting it heat up and feel how hot that is to compare.
Can any Sake be heated?
No! Well... physically yes, but you shouldn't heat most Sake. Delicate Sake containing fruity or floral flavors are usually best enjoyed at cold or cool temperatures. Heating Sake unravels these flavors and sends them flying, causing them to dissipate or vanish completely.
Which Sake Can Be Served Hot?
The best Sake to warm up have fewer delicate flavors and more body. The flavors and body are derived from the rice itself, rather than the yeast. Sake styles such as Futsushu, Junmai, Kimoto, or Yamahai tend to have more of these qualities. Even then you may prefer their flavor cold.
Heating Sake can permanently alter the flavor, so treat it like there's no going back. Try it cold first, then room temp, then pour a small portion to heat seperately to see what you prefer.
How Should I Heat Sake?
Indirect heat is the only safe way to heat Sake. One method is to boil water, pour your Sake into a ceramic carafe (like the Tokkuri pictured), insert a thermometer into the Sake, remove the carafe from the water once it reaches 50°C (123°F) or 60°C (140°F), wipe off the bottom, and serve to the table.
A simpler, more modern method is to place the Sake bottle or carafe in water and use a Sous Vide to heat the water to your target temperature. Always serve in ceramic or earthenware vessels to retain as much heat as possible.
Understand the ceramics will absorb heat initially, so preheat them with hot water if you're transferring the hot Sake from a bottle. Always store Sake cold and away from sunlight when you can, even if you're going to serve it hot.
Can I microwave it?
No!
Really?
Yes, really!
Why can't I microwave it?
Microwaves heat by exciting water molecules to produce heat, warming from the outside-in. Since Sake is never less than 79% water, this denatures (read: *cooks*) all of the delicate and helpful flavors and nutrients in the Sake. Microwaves also heat much faster, making it easier to overheat or superheat your Sake, which is both dangerous and a waste of good Sake.
