Product Review (submitted on November 4, 2013):
Like another reviewer, I used up my culture without making more - but, I made butter out of what I had, so it didn't go to waste!! I'm from Germany and I miss our sour cream butter. Well, no more - I make my own!! AND, I keep my culture going now so I don't run out. This buttermilk culture (like everything from this site) is wonderful! Thank you for giving the public the gift of making our own, clean buttermilk.
