So I have had this idea for a while and I wanted to try it out.I have just harvested WY3787 through the blow off tube. Large pickle jar with some well water. Cold crashed the collection jar after I replaced the blow off tube with an air lock on the primary. Decanted and added 500ml of starter wort to have the yeast stored under beer. Have 250 ml of compacted yeast in a quart mason jar. I'll also harvest from the primary in a few weeks.
So I am brewing a 2.5 gallon batch of a Amber Ale to see if this works. I took the o-ring off of a bottling bucket and put it the top of a mason jar. I am going to boil enough water to fill the mason jar up about half way. So in theory the yeast coming out of the blow-off tube will go into a clean sanitary environment. Thoughts, concerns or advice?
May have been risky using well water in the collection jar, but never had an infection before, or maybe not yet, from not boiling well water for brewing.
