james,
Don't apologize for the quantity you make. I mostly only make 1 and 2 gal. batches. I have made two 6 gal. kits and they are alot more work. The reason I make the smaller batches is for 2 reasons, A) I am usually trying a new recipe and B) we don't drink more than 1-2 bottles a week. I have been doing this for two years now and have 140 bottles on my racks. Going to take awhile to drink those.
As far as bottles, do you have any shops around that sell wine, or wineries, etc.? Or friends of yours, your family, your girlfriend, etc. that drink wine? I have over 10 cases of 750's and 375's that I have obtained for free. Started out with a friend of my wife's, who drinks a lot of wine, would give them to her at work for me. Then I got the winery and shop connection. I now have more than enough to keep over 150 full.
