What are Trappist beers? 

Trappist beers must be brewed or the production supervised by Trappist monks. The proceeds of sales are used for the daily expenses of the monks and any profits are directed to charity.

Most Trappist beers you know like Rochefort, Westmalle or Chimay are from Belgium but there are other countries where Trappist beers are produced such as La Trappe from the Netherlands or Spencer in the USA.
