Belgian Specialty Ale – All Grain


General Info

Named for my father - specifically, the name that his grandchildren call him. This is truly "Papa's" beer.

A bit of history from Wikipedia:

Most Trappist breweries also feature a "patersbier" or "fathers' beer" that is only available within the monastery. This variety is designed to be consumed by the monks themselves, although it is sometimes offered at the monastery's on-site café. The term "patersbier" does not designate a style as such; is usually a weaker version of the one of the regular beers, and may only be offered to the Brothers only on festive occasions, both of these facts relating to the Trappist tradition of austerity.


Added 5g of gypsum to mash water.

Post boil amount was a bit low. Added about 3/4 gal of RO water to the kettle to top up.
