Perfect buttermilk everytime

This is delicious! So easy to make and great to have on hand always. Nice and thick and tart...not that thin, watery stuff you get in the grocery store! I notice the difference in my baking to the positive. Next up, southern fried chicken brined in buttermilk!

Makes the best biscuits and pancakes

I made this Buttermilk culture from our cows milk. Who knew that Buttermilk could smell this good and be this thick! This made the best biscuits and pancakes we have ever had. They were light and fluffy and filled with great flavor. I will make this every time I plan to make biscuits or pancakes!! I am thinking of putting it in my banana bread as well. Can't wait to try it!

Quite a surprise

I had no idea how thick and creamy a real culture md buttermilk could be. It’s so much better than anything I’ve been able to purchase from a store. has a couple of really good buttermilk cornbread recipes that work perfectly to use the buttermilk in.

Easy peasy, no sweat buttermilk.

I love the taste from this culture. I love the taste I'm keeping some of the 1st generation in the fridge and have been using it to innoculate 2nd generation, which I've been drinking like I'm never going to run out. I don't quite follow the directions. I've been using unopened half gallons of two grassmilk right out of the fridge. The first generation used the starter culture, subsequent generations are innoculated with 4 to 6 ounces of the first gen. I make it in half gallon glass milk bottles that have gone through the sanitize cycle on the dish washer as have the caps. Just before making a batch I give the bottles an additional shot of boiling water. The full bottle goes into our laundry room which has a heat vent and gets up to around 80 if we close the door. Eighteen to 24 hours wrapped in a towel on top of the clothes dryer yields very thick buttermilk. At 24 hours you can barely pour it. When the AC goes on I'll have to rethink where I do this. I'll have to rethink the process when

Very thick; mild flavor

Very thick-- sticky thick. To my tastes this is a negative. In homogenized milk, the buttermilk is slick, shiny and creamy as well as thick; in raw milk it is a little lumpy and not quite so thick. My personal preference is for raw milk. In both raw and homogenized, the flavor is mild and slightly lemony, which I like. After two weeks, raw milk buttermilk has developed a tart flavor that is not strong and is acceptable. Good service-- delivery was quick.
