That reminds me of my undergraduate days in Engineering almost 30 years ago. We used to make our own beer, both to save money and to compete in beer making competitions within the Engineering faculty. But there were times when you would run out of beer at 2 in the morning and you had a primary fermenter that had been bubbling away for a week and come to the conclusion - close enough! And the live yeast provided lots of good probiotics for your intestines.
