I am soon to brew a Brewdog Punk IPA. The recipe calls for Chinook and Ahtanium “middle flavour”. Would this literally mean in the middle of the boil i.e. 30 minutes? I am used to flavour hops going in for the last 15 or 10 or 5 minutes?
The recipe that I‘ve got in “Craft Brew“ by Euan Ferguson has the middle hops added at 15 minutes. It’s unclear how long the boil is for but the first hops are added at 80 minutes, so I assume an 80 minute or 90 minute boil.
For info, the fermentation instructions are 5 days at 19/66, then dry hop (with 5 hops) for 5 days at 14/57.
