Nights Watch (Black IPA)

To achieve the dark colour without too much roast flavour this brew required a slightly more complex mash.

For the first 30 mins only the lighter malts were used (Pale, Wheat + Crystal) at the 30 mins mark I added the roasted wheat and Carafa and gave it a good stir. This was then left to rest for the remaining 30 mins.

I batch sparge, so at this point I drained the mash tun into the kettle and added the Chocolate Malt then filled with sparge water, this was left to rest for 10 mins before draining again and starting the boil.
