I set up a calculation for the recipe where the default alpha's were 1% higher than the actual hops I had. I'm new at all this and am just beginning to get a grip on some of the finer points.
This is my second all grain, I was very pleased with my first. I expect I will have much to learn as I continue with my brewing experiences.
I ended up with a calculated actual IBU of 12.2, where I was actually hoping for something in the range of 20-30, the IBU/GU value came out at .25 and is 'cloying'
I boiled 5g of Golding hops for an hour where 10g would have put me closer to an acceptable value.
It was supposed to be a Northern brown and has come out more like a wonky Scottish export.
As you say it is early to judge, I'll wait, bottle and wait some more and see how it turns out.
-------
this is a run down on my brew - I follow it with a 'corrected version' that has a much better balanced profile - what I think it should have been - I'll be giving the corrected version a try shortly
