Just got a bad batch of AF grape myself. Luckily I got some Tangiers White Grape too
Just hate the 'harsh' buzz ish it gives. But eh. Well worth it.
The AF Grape was unfixable. Acclimation. Switching bowls, etc. Never a problem with my phunnel/vortex/ccns though. Or my foil. So its obviously the shisha. Nothing fixes it ;(. Oh well. Only like 11 bucks
