I just made a batch this morning as well! I found a new starter yogurt at the local health food store that claims to have 8 live cultures! It was a bit more sour than my favorite starter, the French Creamline from Trader Joe's. That one is smooth and yummy but only has 4 live cultures.
Can't wait to see how this one turns out. It has only been in the cooler (which is a bit of an oxymoron given that it isn't exactly cool in there) for an hour, so I'll have to wait a while to find out for sure.
By the way, this same health food store sells raw organic milk. The small container (1/2 gallon???) is $8.50! Ouch! I haven't gotten up the nerve to buy it to try it.
