I harkened to the BC board, but this topic applies to Seattle too-
I put soy sauce on everything. Sometimes I will just pour it on toast. Therefore, I must have good soy sauce with me at all times. I'm moving from California to Vancouver -and will be traveling back and forth between Seattle to B.C. - and welcome all soy sauce recommendations.
I sometimes use the Pearl River brand of soy sauce that one can pretty much find in any asian grocery store, mostly out of convenience, but my favorite so far is actually the Ohsawa brand of nama shoyu, which almost no places carry, and which I'd like to know if any place in Vancouver sells. Both brands are great tasting: salty, saucy, tangy and kind of burns if you sip it straight on, and most importantly, not sweet, like Taiwan black soybean brands (probably because of the added sugar).
I really have no preference whether it's tamari, shoyu, organic, gluten-free, whatever. Just none of the fake "soy sauce" crap like ones with MSG or made from coconuts, fruits, or deconstructed vegetable protein dead animals herbal well, you know.
Bonus if the soy sauce is unpasteurized/ nama shoyu.
Super bonus if it is hand made by some traveling hermit that makes only soy sauce to spread to the coastal lands of B.C or south into the forests of Washington.
