I never knew this place existed; not even sure how well advertised they are. We only stumbled upon it because we were trying to get to Coral Castle and saw a small sign for a winery just before we needed to make our turn.
We ended up not going to Coral Castle (here's the http://www.coralcastle.com/home.asp if you're interested) because we were rained out -- it's pretty much an open air structure. So instead of turning back and going home, we decided to look for the winery.
It's located in one of those places that you definitely want a full tank of gas and pray to God that your car is in prime working condition. The signs are small too, so pay close attention when driving or you'll miss it, or think you did.
When we finally got there, we were the only ones there besides the employees (big surprise?). The tour was $10 and it was pretty much like any other winery tour -- we got to see where the wine was fermented, the story behind it, and of course a tasting. The main reason why I wanted to check this place out: the wines are made out of exotic fruits, not grapes. How cool is that?
We tried maybe five varieties (however many they make, I can't remember), I can't remember all the fruits, but a few we tried: guava, carambola (star fruit), and lychee. Schnebly's started off as a fruit packing plant/distributor and kind of fell into the whole wine making. The owners wanted to find a way to use all the fruits that were not suitable to sell.
If this is something that interests you, I can't do it justice. All I can say is it's worth checking out at least once if you're in the area.
Final note: the wines are not cheap, but they are for what they are. They're about $15 each. We bought two bottles (and got a free avocado) and with our tour fees we spent close to $60 with taxes. You do get to keep your wine tasting glass though, which was a nice souvenir.
I'm having difficulty with their web site, but here's the web address www.schneblywinery.com in case it's just my computer or they're having back end issues.
