I am new to this site (thanks for having me) and new to homebrewing (5 months). I have a keezer with 3 taps - 2 x 5 gallon and I recently won a 2.5 gallon keg from local homebrew store. I wanted to get some feedback from experts regarding small brewing. I have 2 x 6.5 gallon big mouth carboys with spigot. I plan to purchase 1 x 3 gallon big mouth carboy with spigot soon. Some beers direct you to add yeast and let your wort then ferment before kegging (this is great I can do small batches in the 3 gallon carboy). Others (I am brewing a 5 gallon hazy IPA right now) direct you to let the wort sit and ferment for a few days then transfer to a secondary fermenter for the remaining amount of time. My question is what issues will I have for the latter if I let it ferment for a few days in a 6.5 gallon carboy before transferring to a secondary 3 gallon carboy.....if any? Will I lose anything? Introduce unwanted anything? Thanks in advance.
