Notes

Batch #2 - 26/07/20 (Eff.: 63%, Att.: 75%, ABV: 7%)

  • Mash vol.: 31.5 L, Pre-boil vol.: 26 L, Batch vol.: 22.5 L
    Substitutes: - All Gladfield malts, (x2, dry pitched) M44 US West Coast yeast in for Nottingham.
  • Mash down to 31.5 L from 32 L, boil time cut to 45 min from 60 min.
    OG: 1071 (Refract.) 1070 (Tilt)
    3/8/20 - SG: 1018, dry hopped 50 g Simcoe instead of 30 g (had it left) and 20 g of Columbus CRYO. Went a little harder on the dry hop just because.
    5/8/20 - FG: 1017, cold crashed.

    Batch #1 - 23/02/20 (Eff.: 56%, Att.: 74%, ABV: 6.6%)
  • Mash vol.: 32 L, Pre-boil vol.: 28 L, Batch vol.: 23.5 L
    Substitutes: - All Gladfield malts
    OG: 1069 (hyd.) 1066 (Tilt)
  • Simcoe hops in for Nugget pellets so weights were halved, old bag of Magnum that was left over.
  • Nottingham yeast used (x2), re-hydrated but not aerated as per instructions.
  • Brewtan B not added at start, forgot.
    26/2/20 - SG: 1020
    1/3/20 - SG: 1018
    3/3/20 - SG: 1017 (Tilt), dry hopped Simcoe Cryo 20g, 30g Columbus
    12/3/20 - Kegged and carbed at 30psi for 2:50 min.
    25/3/20 - Tastes hoppy with a bitter pine finish, hint of toffee and biscuit on the front, easy drinker worth trying again. 4 out of 5 I reckon.
