THE BEST soy milk for coffee has to be Bonsoy - organic Japanese soy milk used in the best cafes and sold only at premium grocers and health food stores. Most soy milks are watery and don't steam well, they don't often turn out creamy unless you are a soy steaming expert (most people aren't cos they hate soy like baristas hate decaf so they don't bother dosing correctly). Bonsoy is great cos the texture is fab and creamy, if you're making a mocha or hot choc 99% of people can't tell the difference between that and full cream milk, and it really does taste great. Most soys override the coffee experience, but this one lets the coffee shine. Never, ever, ever, ever use Vitasoy!!! YUCK!
