Product Review (submitted on February 27, 2012):
I purchased this since I use so much buttermilk in cooking and smoothies. I started off strong, followed the instructions to the letter, and got a nice, thick, delicious batch every time. My house tends to run on the cooler side, and the ideal warm spot ended up being on top of my bedroom TV. Weird, but worked. I did let this die last month, but it's all my fault - I just never kept it going. This is a great culture, and I'm going to order another and stay on top of it.
