I stopped by my local supply shop last night and picked up 3oz. of medum toast French oak cubes and 3oz. of medum toast Hungarian oak cubes. (no rhyme or reason to my selection.) I have a Syrah and a Cab Sav. that are ready for oak. Just wondering what a good method is to doing this? My carboys are topped up. I assume adding the oak will displace some of the wine so I am planning on taking some out and putting it somewhere. (stomach maybe?) I would think just dumping them into the top of the carboy should ok? I have read they will sink eventually.
