I am trying my hand at an extract based Strong Scotch Ale. I got some feedback in a previous thread, but then realized that I cannot do a large enough boil volume.
Somewhere, I read about adding the extract post-boil (or late boil). However, I get weird bitterness values in Beersmith 2 if I drop the amount of extract too low.
I'd appreciate any thoughts or opinions.
7 lbs Amber Liquid Extract (12.5 SRM) - POST BOIL
6 lbs Amber Liquid Extract (12.5 SRM) - boil 60 minutes
11.0 oz Caramel/Crystal Malt - 60L (60.0 SRM)
6 oz Aromatic Malt (26.0 SRM)
6 oz Smoked Malt (9.0 SRM)
2.2 oz Roasted Barley (300.0 SRM)
1.6 oz Fuggles [4.50 %] - Boil 60.0 min
1.6 oz Goldings, East Kent [5.00 %] - Boil 60.0
1 pkg Edinburgh Ale (White Labs #WLP028) - made into a starter
In Beersmith2, this gives the following stats:
Est OG: 1.086
Bitterness 27 IBU's
Est pre-boil gravity: 1.122
When I move more of the extract into the post-boil, the number of IBU's jumps dramatically to over 60 IBU's. Is this due to hop isomerization? Would it really be that high? Or maybe Beersmith2 has a quirk? Or operator error????
Somewhere else, I read about adding all the extract after the boil and reduce hop usage by about 20%????
Any ideas?
Thanks,
Charlie
