So, using the stock I had my recipe was:
Pale 4600g
Crystal 420g
Chocolate 70g
Summit 20g @ 60min
Summit, Citra, Brewers Gold 10g each @ 10min
Summit 17g, Citra 20g, Brewers Gold 20g dry hop
Brewed 4th Feb. On 31st march I was disappointed but now all the hops are coming through and it is really nice. This is much more bitter than my usual brews and I really like it.
Thanks for the inspiration
Summit is a really high Alpha acid hop so your bitterness with 20g for 60 minutes is in IPA territory - depending on your volume, in the region of 50 IBU before your later additions.
If you like the bitterness that’s great but if you make it again you could try 10g (or some hops with lower Alpha acid) for your 60 min addition?
