A friend of mine is a free lance writer and an expert on wine. He writes about wine, thinks about wine, drinks wine and subsequently knows a lot about wine. But he is not a wine snob. In fact, he thinks if you want to drink a $10 bottle of wine that is great and he can tell you what the best bottle of wine for $10 is and where to get it.
He is developing an iPhone app and ask me to create an icon. He is calling himself the Wine Reverend. So, I took the idea of a reverend and the associated space which led to stained glass which led to a stylized bunch of grapes made of purple wine bottle bottoms and a stained glass surround made of the colors that the client said he liked.
