I just finished brewing an imperial milk stout this weekend and am getting some very perplexing gravity readings. The pre-boil/pot-mash gravity came in at 1.084 (which was pretty close to the BeerSmith estimate) and now the post-boil/OG gravity is 1.082! I had a 2gal boil off starting at 7.5 gal boiling down to 5.5 gal. I'm 99.9% sure I read the pre-boil gravity correctly and 100% sure I'm reading the post-boil/OG correctly.
The mash didn't go perfectly... Mashed in and temp started at 162? and took a bit of stirring to get it down to the desired 156?, which took about 20-30min. The mash was also pretty thick because I was maxing out my 10gal mash tun and had no room for rice hulls, so the runnings where super slow. I batch sparged.
Here is the recipe:
10 lbs Pale Malt (2 Row) UK
5 lbs Pale Malt, Maris Otter
3 lbs Caramel/Crystal Malt - 40L
3 lbs Oats, Flaked (1.0 SRM)
1.75 lbs Carafa Special II
1.5 lbs Barley, Flaked
12.0 oz Milk Sugar (Lactose)
0.75 oz Nugget [13.00 %] - Boil 60.0 min
1.00 oz Perle [9.30 %] - Boil 30.0 min
0.75 oz Nugget [13.00 %] - Boil 30.0 min
1.00 oz Goldings, East Kent [4.70 %] - Boil 15.0 min
2.0 pkg Irish Ale (Wyeast Labs #1084) [124.21 ml] (3L two step starter)
Any help/input is greatly appreciated.
Thanks!
