So since I have switched to AG my Apparent (Measured) Attenuation has gone up significantly. When I did partial mash I was getting 75%. Now that I'm AG I'm getting 83-85%.
For example my last batch (brown ale):
OG @ 65F = 1.051
FG @ 65F = 1.008
According to this calculator: http://pint.com.au/calculators/alcohol/
My Apparent attenuation is 84% whereas US-05 yeast is only supposed to attenuate to 75%.
Any idea what might be causing this? My beers taste fine but I'm really not wanting 5-6% abv in beers that only have a 1.050 OG! Do I need to switch yeasts? Mash at a higher temp?
