Yeast is in short supply right now. The last time I was at the brew shop they were almost sold out because people were buying it make bread! So any technique that makes yeast go further is worth trying at the moment. Even when its not hard to get your hands on yeast making your brew a little cheaper is a good thing. This technique using our understanding of yeasts life cycle to seriously under pitch and still get an awesome result. Shout out to Gladfield for hooking me up with this amazing NZ peat malt.
