Yum indeed! I've bought it at PCC and Metropolitan Market in West Seattle, so I assume that other PCC and MM locations would carry it as well. I agree that strawberry is the tastiest flavor, but they're all terrific. Let us know how you like it.
the creamery in pike place market, being a dairy specialty store, carries a larger variety of kefir than available elsewhere - as for culture, use an unflavored kefir featuring live cultures and proceed as for yogurt
No way, raspberry is the best flavor! Just about every major grocery with a health food section will have some brand of ready to drink kefir. I always see it at Fred Meyer. Whole Foods has single serving containers, which is great for taking to work or school.
