I have only made two purchases from Gino Pinto's, juice buckets in the fall and the Carmenere lugs last week, the Pinot Grigio and Sangiovese buckets have already turned into good wines although the Sangiovese needs a bit more aging. The Carmenere is coming along fine.
I don't know what Corrado's is like but Gino Pinto has everything for wine making scaled all the way down to home wine making and all the way up to commercial. Customer service has been top notch. Plus they also have a lot of Italian food imports, olive oil, cheese, etc.
I like Procacci Bros a little better here in Philly, they have a barrel tapped of their own wine and good italian cheeses, meats and bread to consume while you are waiting for your order. But they only have grapes and buckets for the California harvest.
Hope you have a good experience.
