16 Ton Imperial Stout

Tuesday, April 10th, 2012

Pondering a super high gravity imperial based on the 16 ton stout that we brewed for the wedding.

  • 25 lb – 2-row
  • 1 lb – Barley, Roasted
  • 1 lb – Chocolate Malt (could be 50% light)
  • 1 lb – Caramel/Crystal Malt (80L)
  • 1 lb – Cara-pils
  • 1 lb – Kiln Coffee Malt

Plus specialty grains (to total 16 with barley). These are not just going to be adjuncts – they will all be modified or lightly cooked* to help add additional sugars. The plan, is to use 1/2 lb of each (total 7.5 lbs).

  1. Oats (rolled) – brew store
  2. Wheat (malted) – brew store
  3. Rye (malted or flaked) – brew store
  4. Corn (flaked or popped) – brew store
  5. Rice * – my cabinet
  6. Wild Rice * – my cabinet
  7. Tritical *- nuts.com
  8. Buckwheat * – my cabinet
  9. Quinoa * – health food store
  10. Amaranth * – health food store
  11. Millet * – nuts.com
  12. Spelt * – nuts.com
  13. Kamut * – nuts.com
  14. Teff * – nuts.com
  15. Sorghum * – nuts.com

The goal is to reach an OG of 1.131 – This much grain in my tun is bound to lower the efficiency. Up to 4 lbs of malt extract will be added later to reach this gravity. This is very common for an imperial.

Brew notes:

  • Shoot for higher mash 156ish and perhaps a decoction (to create some non-fermentables)
  • Need 75-100 IBUs (including late hops)

Fermentation Notes:

  • After boil, pull off 2-3 gallons in sterile canning jars. Add whatever malt extract is needed and some more nutrient.
  • Pitched on big yeast cake of “Pacman” At 60F.
  • Aerate 2-3 times as much as normal.
  • Add one of the canning jars every few days to feed to wort. Make sure to aerate the jar first.
  • When fermentation finally slows, rack and add a high gravity yeast:
  • 4347  Eau de Vie, or WLP099 Super High Gravity Yeast
  • Batch store for 6 months to 1 year.
  • May need to back sweeten at end.
