After seeing the volcano we went to a winery. It was pretty interesting. The winery was in the volcanic area. They have learned how to grow grapes in the volcanic soil. In addition to wine grapes, I saw fig trees and other vegetable plants.

The wine that I tasted wasn't particularly good - however, that's subjective so we'll just say that I didn't care for it. Your mileage may vary...

This is one of the vineyards. The rocks are built up around each plant to keep the trade winds off them.
