Notes

Mashing Instructions:
Dough malt into 120 degree water. Pull 35% of grist and decoct. Decoction should rest 15 minutes at 147 degrees and boil for 20 minutes. Add decoct to main mash and let rest for 1 hour at 150 degrees. Raise temperature to 160 and mash out.

Extra Ingredients:
Invert and concentrate sugar the week before. Stir constantly and lower heat. Sugar will become thin caramel.

Water should be very hard; similar to Dortmund or Burton-on-trent. High level of Sulfates, Carbonates, and Salts

Yeast:
Wyeast 3787 and White Labs WLP 530 (both Westmalle Strains) should be added right away

Wyeast 1388 (Duvel) and White Labs 550 (Le Chouffe) should be added on day 3

Slurry from bottle of Westvleteren 8 added three weeks into fermentation when gravity falls below 1.025.



Fermentation started at 65 degrees. Temperature raised 2 degrees a day until it reached 85 degrees. Massive starters or starter beers used in all cases.
