I don't get it. Some of the reasons I've just started making my own wine are: enjoying the process, lowering my wine consumption cost and eliminating that "dang I should have bought an extra bottle of wine" feeling that comes after I've realized I've already drank enough to keep me out of the car to go get more.
By my estimation, to recoup the cost of the equipment, assuming a cost of $20 per bottle, you would have to make 25 bottles. At one bottle a week, thats almost 6 months to pay for the machine over bottles from the store. And that doesn't include the $10 kits to make the wine, so tack on another 3 months for that. So in 9 months I can be humming along pushing out about a bottle a week? My wife and I sometimes go through 2 bottles in a night on a weekend!
