Mash Steps

 Name Description Step Temperature Step Time
Saccharification Add 33.60 l of water at 72.9 C 66.7 C 60 min
Mash Out Heat to 75.6 C over 10 min 75.6 C 10 min

Sparge Step: Fly sparge with 47.43 l water at 75.6 C

At this stage, after sparging, the wort was split into two. 27 litres was put into the Braumeister and 30 litres stayed in the gas boil kettle on the HERMS system for 90 minute boil…hops after the first 30 min of the boil…

  • The wort that went into the Brau, took 45 mins longer to reach boil. Consequently, this worked out well. I could finish one wort and chill with the plate chiller before focusing on the other. During this time I cleaned gear and had a quiet beer…..
  • The gas burner is a lot more aggressive…Most commercial systems are electric or steam. Maybe I should have turned it down more….

Vic Secret hops apparently give Tropical fruit, pine and herbs

  • Not a rigorous boil, mechanical boil {thanks Riggers :)}
  • Colour is a bit lighter
  • Caramel not as pronounced
  • Bitterness is more pronounced (out of style?)
  • Pineapple and passion fruit?

  • more boil off
  • Darker

Fuller body? With mild spice and banana

All the beer was kegged and then transferred to bottles, today. You may notice some “carbonic bite …the addition of C02 gives a small bite which is sharper than bottle conditioned beer, in my humble opinion.
