It seems to be a test brew of malic acid + four-stage brewing.
The aroma is slightly apple-like.
The taste is apple-like, muscat-like sourness and sweetness.
The aftertaste is sweet and sour like muscat and refreshing, which is my favorite taste 😋.
I think the acidity mellows out after a few days.
Unfortunately, I can't remember those sweet and sour days like the endorsement says too long ago😅.
