Not sure if this is helpful for you, but for the past few months, I've been making my own kefir yogurt. It's SOOOOO easy! I just got some milk kefir grains from a friend, and all you do is pour milk over the grains and let it sit on your counter overnight, then strain out the kefir grains and eat your yogurt. Then use the kefir grains to make more yogurt, indefinitely. WAY easier than making thermophilic yogurt. You can use whatever milk you want, and flavour however you want - no guessing games at the supermarket. Sometimes I use 10% cream and sometimes I use whipping cream. You can strain the finished kefir through a tea towel if you want thick cream cheese. Cheaper than buying yogurt, and less packaging to throw/recycle, too.
