Belgian Single
>> Saturday, August 22, 2026
Today I'm brewing a Belgian Single, sometimes known as a Patersbier. I brewed a Patersbier years ago and, while I don't remember many of the details, I do remember enjoying it.
Belgian Singles are generally pale, dry, highly attenuated beers with relatively low alcohol compared with the better-known Belgian Dubbel, Tripel, and Quadrupel styles. Despite the lower gravity, a good Single can still have plenty of character from the yeast, hops, and malt.
I'm primarily brewing this batch to enter into a Belgian beer competition. I also wanted to revisit the style since it's been a while, and obviously I don't remember much about that last one. Depending on how it does, I may enter it in other competitions as well, but we are getting towards the end of competition season, and I have a couple other heavy hitters (Florida Rum Barrel Imperial Stout, and MOAR Cherries! Fruit Lambic) that I will definitely be entering.
The BJCP Guidelines describe the style as follows:
A blond, bitter, hoppy table beer that is very dry and highly carbonated. The aggressive fruity-spicy Belgian yeast character and high bitterness is forward in the balance, with a soft, supportive grainy-sweet malt palate, and a spicy-floral hop profile.
Often not labeled or available outside the monastery, or infrequently brewed. Might also be called monk’s beer, Brother’s beer, or simply a Blond (we don’t use this term to avoid confusion with the very different Belgian Blond Ale style). Highly attenuated, generally 85% or more.
Here's the recipe as I'm making it today:
Target OG: 1.052
Target FG: 1.008
IBU: 30
ABV: 5.7
4.66# Solstice Pilsner Malt
4.5# Isaria 1924 Malt
4.8oz Weyermann Acidulated Malt
4.8oz Weyermann Wheat Malt
2.4oz Munich Malt
1g BrewTan B (Mash)
3ml Hopshot (60 min)
28g Sterling (10 min)
Wyeast Nutrient (10 min)
4.66g BCAA (10 min)
Whirlfloc (Flameout)28g Sterling (Whirlpool @155F for 30 min)
SafAle BE-256
Zinc Buddy
Brewing Notes
I was going to brew this beer last night (Friday evening) but I started recirculating my water for heating and noticed a big problem...chunky brown bits in the water. Apparently I forgot to rinse my pump or my RIMS after the last brew, and things had gotten funky. So instead of brewing, I did some intense cleaning and put off the brewing until today.
Mash at 151F, 90 min boil, chill to 65°F then raise to 67°F over two days.

I added 1ml of phosphoric acid to the mash after the initial reading of 5.43. I used my hop spider this time after running into hop debris issues and kegging my recent NZ Pilsner. Whirlpool hops actually got dropped just shy of 140F.
I ended up about 7 points over target, putting my brewhouse efficiency just shy of 84%. I ended up getting exactly 5 gallons in the fermenter. Given that this yeast is known to be pretty active, I'm hesitant to add any volume (messy blow-off) by diluting the wort, so I'm just going to let it ride a few points high.
I was able to chill down to about 60F, but by the time I got the fermenter in the ferm chamber, it was closer to 64F.
