What is the kit. I did a Northern Brewer Nut brown extract kit as one of my first few brews. I was reading reviews and lots of folks added various things to bump up the ABV. I followed the recipe with no additions and it turned out well.
Just wondering if you are tempted to make additions based on reviewers or something else. For most of the big vendors I would imagine a fair amount of thought goes into their kit recipes. Perhaps I am naive in this regard.
If it is a tried and true recipe from a big vendor I would leave it as is. Try it and if you want to make changes brew it again. Without a baseline sample it's hard to know what to do.
If you have already tried the base recipe you can disregard this rambling post of mine.
