Last night I brewed my second batch of Northern Brewer's Zombie Dirt Pale Ale. I used the extract kit and followed the directions as called for in the recipe.
According to the recipe, the extract ingredients should have an OG of 1.060. The first time I brewed the beer, that's exactly the reading I got. But this most recent batch has an OG of 1.080.
I brewed the beers nearly identically, the only difference being that I added a scant teaspoon of Irish moss at 20 minutes remaining in the boil.
Here's the extract "grain bill" for the recipe:
- 0.5 lbs Carapils
- 0.5 lbs Medium Crystal
- 3.15 lbs Gold malt syrup
- 3.15 lbs Munich malt syrup (10 min)
- 2 lbs Golden Light DME (10 min)
Any ideas what could cause such a high OG reading? I'm pretty confident the reading is accurate, but perhaps not.
