Eric Mead's book "Tangled Web" is great for this environment.
What you want is stuff you're very comfortable with, and that you can make sort of modular. Because you never know when you might have to end, or extend, suddenly. So being able to jazz a bit here is great.
So, the generic recommendation is to have 3 sets of 3 tricks. These will be things that can be reset easily, carried in a pocket, etc. Aim for maybe 10 minutes. I also like to keep a few "show piece" tricks on deck. Those will be things that require more set up, or can't reset easily, but are really good. So maybe I won't do them at all, but if I have a desire to do something extra special for a group or VIP, I have it on hand.
Since this will specifically be a winery, make sure you have material that's very easy to follow. This is not the environment to get into philosophical presentations, you'll want stuff that they'll still remember what's happening by the time you get to the end.
Oh, and wear comfortable shoes that look nice.
