homebrewed belgian quadrupel

belgian quad straight from the tap

about a year ago I decided to brew one of my favorite styles – a belgian quadrupel.

  • I love the general complexity, intense flavor, and alcohol bite of a well-made quad.  some of my favorite (accessible) quads are pannepot old fisherman’s ale, st. bernardus abt 12, and rochefort 10.
  • I especially enjoy the “cola” flavors of the 10, so I initially was planning on brewing a clone of that brew, but BYO came out with an extract clone recipe for the abt 12 that looked too good to pass up.  I can’t find that issue for the life of me, but I managed to find the all-grain counterpart online:
    • St. Bernardus 12
    • OG=1.103
    • FG.=1.017
      IBU=15
      SRM=37
      ABV.=11%

      10#’s Pilsener malt
      3.0 #’s Munich malt
      1.0 #’s aromatic malt
      0.5 #’s Carafa Special III malt
      3.0 #’s Belgian candi syrup (Dark 2) (15 min)
      3.5 AAU Wye Challenger hops
      (60 min) (0.50 oz. 7% alpha acids)
      1.3 AAU Styrian Goldings (20 min)
      (0.25 oz. of 5% alpha acid)
      Wyeast 3787 (Trappist High Gravity) yeast

      Step by Step:
      Mash with a 15 minute rest at 135 deg.F, a 35 minute rest at 145 deg F, and a 25 minute rest at 165 deg F, a 5 minutes at 172 deg F. Boil wort for 60 minutes, adding hops and sugars at times indicated in the ingredient list. Cool wort and aerate. Pitch yeast at 70 deg. F. Let fermentation temperature rise to around 83 deg F. Rack beer to secondary and condition for six to eight weeks at 50 deg. F. Carbonate to 3.0 – 3.5 volumes of CO2.

  • I remember that I may have substituted 1762 for the 3787, but it was a while back.  both yeasts seem great for this brew.
  • A few weeks back I tapped the keg (after close to a year in secondary), and was definitely satisfied with the results.  The beer has a fruity, mildly alcoholic nose, and is smooth and drinkable with good mouthfeel.  The taste has hints of cola and molasses, has fine carbonation, and leaves a sticky sweet finish in the glass.  There is plenty of this beer left, and you can only drink so much at a time, but I am already dreading the eventual kicking of this keg!

single hop fresh hop vojvodina pale ale brew day

on the vine

so, my homegrown vojvodina hops appeared to be ready for harvest.  the cones were light and had a papery feel, and the cones themselves appeared to have a decent amount of lupulin in them:

after some research, I found that vojvodinas are a hybrid of northern brewer, styrian goldings, and a wild yugoslavian hop.  therefore, I based my recipe off of a single hop northern brewer recipe and adjusted it with respect to other input from various sites.  I also multiplied the required amount of dry hops by 4 in order to account for the use of fresh hops (many sites say to multiply by 4-5; I went with 4 mainly because my plant ran out of hops!).  here’s my recipe:

  • 8lb pale LME
  • .6lb pale DME
  • 8oz cara-pils (@150 for 30 min)
  • 8oz crystal 60L (@150 for 30 min)
  • 4oz fresh hops @ 60, 30, 5 min

first I weighed out the specialty grains and steeped them from room temp -> 150, then held at 150 for 30 min.  I used a grain sock instead of a mash tun since the specialty grain bill was very small (1lb).

steeping grains

after hitting 150 for 30 min., I removed the specialty grains and added the extracts.  I added a little more DME to compensate for the fact that I hate squeezing every last drop of LME out of the extract bag and usually leave at least a few ounces in the trash can.

then I got to picking the hops while waiting for the boil.  CB and AF rolled by to participate in the “harvest.”

picking the cones

the volume to weight ratio of the fresh hops was pretty deceiving.  after picking a bowl full of hops, I figured we were going to have well over the desired 12 oz.  however, that was a small overestimate:

not quite 12 oz

the first batch of cones got tossed in at 60 min and the picking continued.  we ended up picking the hop vine clean, for a total of just over 12 oz.

hops in the kettle

the starter worked great, and the fermentation took off quickly and vigorously. I’m going to give it a week or two in primary, then secondary while carbing in a keg.

the end result – months of anticipation culminating in tossing a bag of hops and sweet wort in the compost.

to top off my brew day, I primed and kegged the presidio blackberry kolsch, kicked the tripel keg (finally!) and bottled some of it, cleaned my beer lines, and tapped the abt 12 quad semi-clone (review soon – it is pretty awesome).  phew!

and what’s a brew day without sampling a few beers to aspire towards?  I popped a bottle of la folie, while CB brought over a great valley brew IPA and deschutes’ black butte XXI porter. thanks again man!
