I admit that I'm fond of an ice cold beer in the summer. And though I'm not as fond of beer in the winter, I've never let that stand in my way. Some vegans and vegetarians, however, might be unaware that animal and animal by products such as Isinglass are used during beer and wine production. Here is a handy iPhone app from Matthew Feinberg that can tell you which ones might be vegan or vegetarian friendly. It does a search through the Barnivore Vegan Alcohol Directory. Very handy. Barnivore welcomes contributions from the vegan community as well. So, if you've done some checking on one of your favorite drinks, you can provide them with what you found. Drink up and enjoy!
