We have a batch of beer that has been in primary for about a week and we are getting ready to rack to a secondary fermenter. We want to experiment with the difference between doing primary only and both primary and secondary fermentation. We have 5G total and are planning to transfer about half into a 3.5G carboy and bottling the rest now.
However, for primary-only we've seen recommendations to leave it for two weeks, so I'm a little concerned our test isn't really going to contrast the two approaches. Will there be a significant difference between:
- bottling the primary-only batch after a week but leaving bottles for the extra week to let the primary-secondary batch catch up and
- leaving the batch in primary for an extra week (assuming we weren't disturbing it by transferring a lot of it for secondary) and having it bottled for a week less?
