I am brewing a double IPA. The recipe calls for dry hopping. After racking from the primary (6gal) to secondary (5 gal), I had an extra .5 gallon left over. I racked the remaining beer to a glass growler. When I go to bottle, can I combine the 5 gallon beer with the other 1/2 gallon? Or should I prime the 1/2 gallon and bottle it separately?
