Let's play a game. Look at these six wines and see if you can name the producers. Then decide whether the price of each was more or less than $20
Wines are intended to be stored lying down, which makes it difficult to see the labels but easy to see the tops. Yet so many wineries use cheap plain foils, making it difficult to identify wines easily. Of the six wines pictured, the three with generic foils all cost over $20; the others cost $20 or less.
So what are foils for anyway? According to Paul Romero of Stefania Wine, their primary purpose was to detect tampering by unscrupulous household servants. Since so few of us have butlers these days he didn't see the point, so has eliminated them.
Another problem with foils is that they obscure the cork. A cork may be failing or a bottle may have leaked, but until you remove the foil it's impossible to tell. Some wineries such as Ridge use short foils so that the base of the cork is exposed, but they are in the minority.
So here's a request to all wineries still using generic foils - please consider why you're using them. Are you trying to hide the poor quality of your corks? Are you convinced that without a generic foil your wines would be easier to fake? Or is the implication that your wine is as generic and boring as the foil?
