I used the AK 47 mild extract recipe with dry yeast and added green apples to the 60 minute boil. Like the taste and aroma but I was curious if there was a way to just increase ABV? It was a low 3.0%. Thanks for the help.
You could use table sugar. However, that beer is a Mild and it might not taste "great" if you increase the ABV. Milds aren't meant to have alcohol flavor, but are easy drinking beers that you can have a few of and still function.
But table sugar should do the trick. Just add the amount desired, boiled in a pint or so, cooled and added to the fermenter.
