Help With Yankee Units.....

[sinkas]

Hi all,
I saved this yankee IPA recipe a while back, but now that I would like to use it, notice that its got some weird units,

So for the hop additions marked "AAU" how do I work out how many IBU's?

And doe sanyone have any idea what volume this brew might be, maybe 5 gallons or is it 10?

Finally, what do you think the values in brackets after the specialty malts mean?

IPA Recipe

OG: 1.073 FG: 1.014 IBU: 93 SRM: 9 ABV: 7.5%

14.66 lb. Gambrinus 2-row pale malt
2 oz. crystal malt (15 L)
2 oz. CaraPils malt (6 L )
2 oz. Munich malt (10 L)
2 oz. wheat malt
1 oz. honey malt

7 AAU Columbus hops (FWH)
7 AAU Simcoe hops (FWH)
3.25 AAU Columbus hops (60 min)

15lbs is around 7Kg (6.8). In a normal 22 or so L batch that would giev you an OG of around 60-70 depending on efficiency if my memoy servers me corectly. Thats about right for an IPA.

As for AAU, this is the same as the old HBU - %AA * Number ounces. So 7AAU of cascade (which is usually around 5%AA) would be 7/5 = 1.4oz.

That must be a pretty old recipe. i don't think anyone has used AAU or HBU for ages.

Cheers
Dave
