You can't get accurate readings using an alcohol hydrometer (proof/tralle hydrometer) with beer. They are only accurate when testing mixtures containing only water and ethanol. Finished beer contains water, ethanol, proteins, dextrins, and multiple other components that cause higher SGs than mixtures with the same amount of water and ethanol but nothing else.UPDATE:
It's been 19 days since I bottled this brew, so I opened one. The carbonation level is about perfect. The flavors are still a bit "harsh" but definitely drinkable. I'm going to age it and test one/week to see what is optimal. The only comparison I have is making wine- and I know from experience that freshly bottled wine is "harsh" compared to letting it age, so I'm going to assume the same for the stout. I broke my low-scale alcohol meter so I don't know what the final ABV is, but based on the unscientific "buzz meter" in my head, it is close to 11.
Brew on
