The assembled brew kit. Left to right: Paddle (made by Rob), lauter tun, kettle (for mashing and boiling) atop 8kw propane stove, hot liquor tank (Burco, at the back!).
Recipe:
Grains: 2.5kg lager malt, 2.5kg wheat malt
Hops: 1oz Saaz
Spices: 1oz crushed coriander, 1oz orange peel (off a fresh orange)
Mash: Step mash in 16ltr of filtered water, water pH pre-adjusted to 6 with carbonate reducing solution (CRS). Mash adjusted to pH 5.2 with lactic acid.
Schedule: 15 min at 50c, 30 min at 62c, 15 min at 68c, 10 min at 70c, raise to 78c for mash-out.
Boil: Boil 1 hour with hops. Spices added at flame-out.
Cool: 30 mins with immersion cooler
Result. Collected only 19ltr at 1050. The mash volume should (by my reckoning) have been only 13 ltr - may have caused an inefficient mash.
