Wee Heavy/Strong Scotch Ale | Strong Scotch Ale


  • For 5.5 US gallons (20.8 L)
    • 18.25 lb. (8.28 kg) Golden Promise pale malt
    • 8 oz. (227 g) 500° L roast barley
    • 3 oz. (57 g) East Kent Goldings, 5% a.a. @ 60 min
    • White Labs WLP028 Edinburgh Scottish Ale or Wyeast 1728 Scottish Ale yeast (preferably fresh yeast slurry from a Scottish ale.)
    • 1 Whirlfloc tablet or 1 tsp. (5 g) Irish moss @ 15 min
    • 1/2 tsp. (2.2 g) yeast nutrient @ 15 min


    • Original Gravity: 1.091 (21.8° P)
    • Final Gravity: 1.025 (6.3° P)
    • ABV: 8.8%
    • IBU: 36
    • SRM: 20


    Mash grains at 152° F (67° C) for one hour. Mash out at 168° F (76° C), and sparge at 170° F (77° C). Collect enough wort to account for evaporation from the long 120-minute boil.

    After an hour, add the 60-minute hops. At 15 minutes, add either 1 Whirlfloc tablet or 1 tsp. (5 g) of Irish moss and the yeast nutrient. After the boil, stir wort vigorously to create a whirlpool and precipitate out the trub. Chill wort to 63° F (17° C) as quickly as possible, run off into a fermenter, pitch yeast, and oxygenate for 1 minute using pure oxygen.

    Fermentation should be allowed to free-rise to 67° F (19° C) during the first 4 days. It can then proceed at that temperature for another 2 weeks, or until terminal gravity is reached. Transfer to secondary (glass or stainless steel preferred), and cool to 36° F (2° C) and cold condition for 2-4 weeks. The beer can then be conditioned in kegs or bottles for up to 10 months at cellar temperatures before serving.

    Extract Version

    Substitute pale malt with 13.75 lb. (6.24 kg) Maris Otter liquid malt extract. Decrease roast barley to 6 oz. (170 g) and steep in 155° F (68° C) reverse osmosis (RO) water for 30 minutes. Dissolve extract and top up to desired boil volume with RO water. Add hops and boil 60 minutes. Proceed as above.
