OK, I just Finished step 3 of my Cab which called for racking, degassing, stabilizing and adding 3 (?) 4oz pkg hungarian med toast oak cubes. I'm to rack off in 10 days then either bottle or add sulphite/bulk age in another 28 after racking. My instinct is to leave the oak cubes in for longer, the full 28 days then rack to a 5 gallon carboy and proceed to bulk aging. The other issue is that I'm looking at about a 3 bottle's worth of head space. Too much time on the oak? Too much head space for a month?
