I've made this, followed Ken Schramm's recipe to the letter. The juice I used was fresh pressed from the orchard & was pure MacIntosh juice, very high in malic acid. Even though the FG was 1.010, it doesn't taste sweet at all. Next time I'll do a MLF to soften it it up a bit, or use different juice. In order to drink what I have of this, I heat it in a pan on the stove & add a couple teaspoons of sugar (white or brown) and a cinnamon stick. Don't let it boil or the alcohol will evaporate, just hot enough to pour into a mug & enjoy a nice hot toddy on a winter day. And to answer your question, yes, it WILL mellow a bit with time. Regards, GF.
