I am assuming you are all-grain, which is good as aromatic malt requires mashing and there is no real substitute for it.
A little roast barley will go a long way, so be careful with using too much.
As for using 13# 2-row, at 1.062OG, this is not unheard of, depending on your efficiency.
Also, from that link the description says:
"A blend of six malts, some of them roasted, give this beer its deep russet-brown color and complex malt flavor, fruity, smooth and rich, with a caramel, chocolate and coffee background."
So you are likely missing some grains. I have a brown that I just bottled that was inspired by BB, though I wasn't going for a clone. I went with:
9# US 2-Row
12oz. Aromatic
12oz. Crystal 60
8oz. Chocolate
4oz. Roast Barley
1oz. Fuggles (4.2%) @ 60 minutes
1oz. Willamette (4.0%) @ 15 minutes
1oz. Cascase (6.4%) @ 15 minutes
.5oz. Wilammette (4.0%) @ 5 minutes
I got a hair above 80% efficiency, mashed @ 156F, came in with OG of 1.060. This fermented in the low 60s for 4 weeks and finished at 1.016, using S-05 yeast. My hydro sample was very good - I'm really looking forward for this one to carb and mature.
If you are going for a clone, I would use WLP002 (or equivalent) and mash high, to get it down from 1.062 to 1.019.
Akimbo,
I want to brew a brooklyn brown ale soon. I went to the brooklyn lager webpage and found the ingredients for their brown ale, but being new to homebrewing I am not sure the amounts to use.
This is their spec sheet:
http://brooklynbrewery.com/brooklyn-beers/perennial-brews/brooklyn-brown-ale
Here is what I am intending on using:
Pale Malt (2 Row) UK
Roasted Barley
Aromatic Malt
Fuggles
Cascade
Willamette
Irish Moss
American Ale Yeast
Ferment at whatever temperature the yeast do best at for 30 days or until the SP is steady for 2-3 days in a row.
I tried using beersmith but can't get the numbers to match up, If the numbers do match up I am using 13lbs of Pale malt for 5 gal???!!!...
Any suggestions, comments?
any assistance would be greatly appreciated.
Thanks again for your help and assistance in advance.
