RCGoodin...
Even whites aren't really at their best in a couple of months. I started a Winexpert Selection Limited Edition Alsatian Riesling way back in Oct 2009. We've had the occasional bottle to drink since then, but I was REALLY impressed by the bottle I opened last week. 2 years after starting the kit!!
I ran a Ferment on Premises which means customers make wine in the store. That wine tended to be consumed immediately or soon thereafter. No matter how often I suggested that they allow it to age. So the wine will be drinkable whenever you want to drink it (even the red). Do yourself a favor though, and keep some for a year or two. The difference might surprise you.
You asked about starting a store. For me opening an FoP in British Columbia, there were two major steps...
1) learning about opening a store, running a business, etc. There was a government program that helped a little. Some friends helped a lot more, especially with the physical details.
2) applying for and receiving a liquor license. This was only required because it was a FoP.
I contacted a couple of wine kit manufacturers and they were happy to start selling me goodies. I visited two in Vancouver (one was very helpful), a third visited me, and I never managed to get together with the fourth. I know that Tim from Winexpert has said that WE is willing to talk to peopple about opening a store, so try contacting the US distributors.
Startup costs will vary a lot. I started with a blank slate, a brand new building, so did slatwall, a couple of interior walls, etc. Plus I put in big sinks etc and bought equipment (lots of carboys, expensive corker) for making wine on premises. If you`re just doing retail, you may find a location that just needs some paint and shelving. (BTW, small store in a small town. We max`d out at 100 batches on the go at one time.)
The store closed because the landlord did not want to renew my lease, and I did not want to start over in another location. The business that the landlord wanted to run where my store had been never amounted to much. So he closed that business and his laundromat, and turned it into a pizza place. Our friends that still live there said it wasn`t very good, and it soon went under. He shoulda left me alone.
