Hi,
We are brewing 20 gallons at a time and have had a couple of batches go bad. The taste is fine after first fermentation and the same when we keg. After a few weeks, we taste and have a spoiled product. It taste a bit funky, not right. We are thinking that it is a yeast issue.
Here is our process and some results.
First, we are extremely carefull to sanitize everything.
We have been starting with fresh yeast and then re-pitching it for the next four to five batches.
This has worked ok but what is your take on that? We also re-pitch to different styles for example, we may start with a brown ale then the next week make a porter and then a red ale. Is it a good idea to use the same yeast in different batches/styles?
We made a great oktoberfest last year with fresh yeast and then about two months later we made another batch pitching yeast that has been reused for 4 or 5 batched. This batch of oktoberfest is not good.
Should we only re-pitch yeast to make the same style? How many times can you do this?
I'll stop here and wait for advise. Please let me know if you need more info.
Thanks,
Noodle
