So, I was checking the gravity of my Imperial Rye PA, Billy Rye Cyrus, with my wine thief, and afterwards, realized that I'd only used 1 tsp of Iodophor, instead of the two I usually use. I thought I was measuring in teaspoons, but I'd grabbed the 1/2 teaspoon, instead. This was right before transferring it to the secondary to dry hop. The gravity was right where I wanted it, and was at 9% ABV. Should I be worried? I'm hoping that it being so alcoholic will nullify my stupid mistake.
