Harry Crowther - Grain to Grape The Big Vin Theory

We talk to Harry Crowther, founder of Grain to Grape.  Harry is a winemaker and ex-somm who runs Grain to Grape - a wine training company with a difference. We ask how sales can be maximised in the on-trade?  How can and should people up-sell in a restaurant?  How can wine work for mixologists and those without a wine background?  What are the new social media platforms we should be paying attention to?  Follow him on all the social media platforms he mentions with @graintogrape
