What is the best final ABV % to aim for vodka & cranberry for: served chilled? served chilled over rocks? For straight serve, I used Ocean Spray brand with 95% neutral grain spirit to yield 15% ABV and it tasted decent. It didn't taste too strong, but alcohol can be tasted. It didn't have a chance to sit long thanks to other people, but the ABV should be high enough to halt microbial activity so it would last a few months without rotting in the fridge. I like the idea of making a gallon or so in advance, so I don't have to prepare it every time and I want it to taste the same every time.
