All-Grain - Cascade of Bitterness

**bradsul** · 09-14-2008, 01:17 AM

Recipe Type: All Grain
Yeast: Nottingham
Yeast Starter: No
Batch Size (Gallons): 25L
Original Gravity: 1.057
Final Gravity: 1.012
IBU: 70
Boiling Time (Minutes): 90
Color: 10
Primary Fermentation (# of Days & Temp): 21 Days @ 65F
Secondary Fermentation (# of Days & Temp): 21 Days @ 73F
Tasting Notes: Showcases the flavour of cascades but also has nice malty background.

Everybody gives me a strange look when I say I don't like cascades all that much so I thought I'd give a full on American IPA a try and see how I like it. Well I really do and this one will definitely be made again soon.

It has all the great cascade flavour you would expect and a really nice malty/toasty malt flavour from the Vienna and Munich malts. The caramel flavour from the carastan (crystal 60L) is present but you have to be looking for it.

The next time I make this I'm going to try some US-05. I don't expect any difference in flavour but it will keep to the theme of the recipe.
