"At the risk of overgeneralizing, many sake experts say that ginjo and daiginjo sakes are usually best not warmed (since being served chilled enhances their flavors and aromas)"
It is bizarre you go on these rants about how people on Hacker News aren't cultured like you after all your time in foreign cities, but you didn't visit the main neighborhoods, chose a few bad restaurants on Yelp, and clearly don't know how the locals prefer to drink their sake even after bragging about all your experience. Since you don't even drink, maybe you should listen to the people who do and who have toured the sake factories.
Way to be totally obnoxious and ruin the normally polite discourse here. You're posting on a brand new account and already getting flagged for abusive posting. You're not even trying to have a productive conversation. Go argue with people on Reddit.
as far as sake.. i don't drink anymore, for a while now, but you're wrong. serving it warm brings out the taste, and makes any cheap nastiness worse. serving it cold is what hides it. having a store that only sells sake does not make it 'the store for sake.' there are many stores stateside that have a good sake selection. they also sell japanese beer and plum wine. and in the style of true sf culture, you just said japan has crappy sake, which is why they serve it warm, while sf is doing the traditional japanese wine correctly. this -people like you on every corner, is why i didn't like sf. it's the culture -or lack thereof.
