I brewed a mini-mash batch last night and I missed my OG by 16. However, I'm wondering if I really did? Here's the recipe and what I did:
1/2 lb 60 crystal
4 lb light DME
2 1/2 lb dark DME
2 oz. Tettnanger (bittering)
1/2 oz. Tettnanger (aroma)
1/4 oz. Hallerttau (flavor)
1/4 oz. Hallerttau (dry)
My boil was right around 2 1/2 gallons. I chilled the wort down to around 80. I had 4 gallons of spring water in jugs that I had on standby in the freezer (they had been in there for about two hours). I first added a gallon of the spring water to the primary fermenter and then poured the 2 1/2 gallons of wort on top of the gallon of spring water. I then added more spring water to bring the total volume up to 5 1/2 gallons. I now realize that I took the hydrometer sample prior to shaking the fermenter to aerate the wort.
According to my recipe on Brewmaster's Brew Builder my OG should be 1.056. The sample I took had a SG of 1.040. Could it be that my sample was just more spring water than wort? The spring water was also colder than expected and brought the temp of the wort down to around 54. Would the cold temps effect the gravity?
