The newest black magick is exactly what you would expect 4 roses black magick to taste like - on par with all other recent black magick barrel iterations.
Zangy is pretty awesome. Even though its a little higher in alcohol than black magick, it doesnt taste any more boozy than BM. I felt it was a little less sweet than BM and had more layers of barrel character.
Unbarreled black magick is the hero noone seems to talk about. I love its smokiness and would kill to take some of that home in a future barrel room release.
Havent tried the quad yet
Edit... and I basically just repeated what
