BJCP 2021 Style 34C Experimental Beer

This formulation is my interpretation of the recipe designed by David Heath (David Heath Homebrew) and Andrew Paterson (Lallemand) (Youtube video The name is mine though :-) It utilises a very high mash temperature, some carapils to add mouthfeel, some unfermentable sugars and a low attenuating yeast. Also, high quality aromatic hops.

I did this version on my very simple stovetop setup - coolbox MT, stockpot, jug for vorlauf. Double strength grist (ie for 5l batch), liquored back to 10l post-boil.

Tasted at April 2022 meeting with enjoyment from all.
