I recently signed up for LivingSocial. It’s one of those sites that offers discounts on local services, products & experiences for a limited time. Last month I received one about an “adventure” being held at Andretti Winery in Napa. When I read the part about Andretti I was instantly in, I knew it would be a great thing to write about here and I didn’t even know that Mario Andretti owned a winery. So in addition to writing about tasting the Andretti wines, I also get to tell you about the mustard-making class that was also included.
