Been homebrewing for a year and half. All grain after a few extracts to start off the hobby. I seem to regularly miss my target gravities by a a double digit margin most of the time. I don't know why. I mash in a rectangular cooler and have trouble hitting my mash temp dead on about half the time.
Yesterday i tried brewing a Hair of the Dog Adam Clone recipe and had my worst results yet. The target Pre-Boil Gravity was 1.066, mine was 1.054. A 3 hour boil was supposed to yield and OG of 1.022. I boiled off nearly 6 gallons in that time and only made it up to 1.066.
What am I missing here. Do I have bad equipment? (Refractometer) How can my gravity have only increased so little with that much of a boil?
This is the version of the recipe I followed:
6 gallon batch size
Est. OG 1.122
Est. FG 1.030
21 lb 9.9 oz Pale Malt (2 row)
2 lb 7.3 oz Caramel/Cyrstal Malt 40L
2 lb 2.6 oz Munich 10 L
13.8 oz Peat Smoked Malt
11.2 Chocolate Malt
5.6 oz Black Patent
Scottish Ale Yeast Wyeast 1728
