Everything oak related, since I just secondaried with some medium toast cubes. What flavor toast do you prefer? Oak chips, or Oak cubes? (or barrels?) What is your preferred method of sanitizing? What is your favorite specific brand of spirit to soak your oak in? If you don't sanitize with spirits, how do you do it? How long do you let your beer age on oak? What temperature do you age your oaked beer at? Do you cold crash after oaking?
