1st is a primary, 2nd is a secondary, 3rd is a tertiary. Does anyone know what 4th would be?
I love using the word tertiary (ter-she-air-e) to mean that you will have to transfer a second time to a third carboy. People think a Tertiary is a special piece of equipment.
First off, you should always use a secondary it makes better beer. You can put the fruit in the primary if you want but I think you would get more flavor from the fruit by adding it to the secondary. If you add the fruit to the secondary, I highly recommend transfering to a tertiary carboy. Adding fruit takes several transfers to clear the beer so it doesn't look like sludge.
