I am making a RJ Spags EP Cab and a Cellar Craft Showcase Zin. I am bulk aging for 6 months. I have American medium toasted oak cubes I bought seperately. What will these do if I add to bulk age process? I consider the Cab somewhat 'flabby' right now, although it is young. Will oak firm it up and give it more complexity? The Zin had 2 packets of oak 'dust' that I added already in case there is a threat of over-oaking. I guess what I mainly want to know is what will adding oak for a period of time do to structure/flavor of wine? Thanks!
