Couple more things about that:
1. It's always easy to add more oak chips later if you think the oak flavor
isn't strong enough. Kinda hard to take it out if you think it's too strong;
about the only thing you can do is to blend the wine with another batch of the
same stuff that hasn't been oaked.
2. If you need more oak chips, you can probably get them at the same dealer
where you bought the kit. If not, there are certainly plenty of online
sources, e.g. http://www.greatfermentations.com http://midwestsupplies.com
