Howdy and Welcome James...The choice of the kit was twofold. First, my wife is a fan of sweet wines, with Reisling near the top of her list. Second, the homebrew shop I visited made me an offer I couldn't refuse. They had two of the RQ kits that were approaching the end of their shelf life. 50% off is hard to turn down!
As far as cellar location goes, we have a small utility room in the lower level of a split level. Sized about 6 x 10. Temp remains between 60 - 70 year round. Once I remove all of my tools from it, I think it will do fine. (Any good recommendations for wine racks?)
As far as the next style of kit, I'm up in the air between the Aus. Meritage and the Super Tuscan kits. Both lean towards my preferances (dry, bold, reds).
