Question:

There are many beers manufactured by monasteries—they are called trappists or abbey ales. Some examples: Chimay, Orval, and Floreffe. I think that Benedictine liquor is also made by or in a monastery. Can I drink a beer or liquor that was made by a monastery? Is it wrong to support such causes?

Answer:

Regarding Benedictine, according to their website, the recipe was originated by a monk, but commercial production is not directed by monks or a monastery. In the 1860s, a relative of the drink's creator found the original recipe and began producing it for commercial purposes.

Nevertheless, you may purchase and enjoy even such drinks that are produced by monasteries. A monastery is not a church, it's a dormitory. The income these beverages generate go towards the monks' living expenses—which poses no problem at all. So from this angle the beers you mention are all okay, just make sure that they are kosher!
