How Long Sake Lasts

Sake will, of course, last longer when it is stored correctly.

The question of how long sake lasts is actually quite difficult to answer and, certainly, there are a few breweries experimenting with ageing and maturing sake longer than what we traditionally consider a ‘safe’ or ‘wise’ period. This process is distinct from koshu (intentionally aged sake for longer than three years) which tends to have rich and deep umami-led flavours, often they are quite sweet too. What I’m talking about here are brewers who are either maturing their sake themselves for prolonged periods of time (but generally less than three years) or designing the sake to be sold ‘fresh’ and then develop over time. Some brewers are even doing this with namazake (unpasteurised sake), some Muroka Nama Genshu (unfiltered, unpasteurised & undiluted) rather suit a bit of maturation! (more…)
