I have tasted the apple mint brew and I must say, it is highly unusual. Almost impossible to describe. Tastes more like a strong wine or even like sour liquor. I will call it the sour apple blend. It's very unusual and curious how it tastes as it ages.
I have an aggressive chocolate mint plant. It wants to take over every inch of land. I wonder how it'd taste as a brew. What are you using as a base for your herb type beers?
