I also wanted to use up some of my older hops and this recipe seemed to tick all the boxes. Plus if the yeast doesn't turn out very well and I have to throw the batch away then I won't feel too bad about the waste of hops, being the price they are at the moment.

I'm mashing at 66C with 2.4Lts/Kg grain and currently waiting for the enzymes to do their thing
