The "wine cooler" kits (i.e., Orchard Breezin and Summer Breeze) aren't going to improve much (if at all) with age, so they will be ready to drink within two months. If you like the light sweet summer-y wines, then that's the ticket. And the time is right to get some made now for the June-July August timeframe.
But if you were hoping to make elegant, silky, hearty reds in 2-3 months, then you're out of luck. Those are the ones that take 1-2 years. I just had the last bottle of a MM Alljuice Caberlot (cabernet-merlot blend) that I bottled in June 2009 - really good, although it tasted about the same last fall; much better than it did in the first year, however.
