I wrote about my adventures to Barrel Oak Winery with the intrepid Emily. We had a great time, with great views, and decent wine.
This covers a lot, including buying bottles of wine. I recommend using it on a nice picnic. They have great heated brie there that goes well with their warm baguettes.
You can also bring extra food if you’d like. There are plenty of picnic tables plus spaces to spread out a blanket.
Also if you (like me!) tend to forget about your vouchers, here’s a handy guide on how to keep track of which vouchers you still have outstanding.
