- So, are those wonderful Greek and other unsupervised yogurts kosher?
- In places where it's hard to find any certified kosher products can you eat the yogurts?
This Shabbat (in Torah Tidbits) I read an article which answered the question. Easy to Eat, Complex to Certify: Yogurt is a Favorite Food for the Cultured Among Us. It answers those questions, and the answer is very clear, a simple "no."
The following sentence summarizes the article, and I suggest you read the article very carefully:
"Of all dairy products, yogurt is among the most complex in terms of its kosher requirements and proper supervision."
