Not my favorite juice. My initial taste reaction was "WOW, so much grape and so sweet!", then the diet soda aftertaste swept in. I would compare it to Diet Nehi Soda. Sweet start and diet finish :( Any claim of butter was lost in the background from the obnoxiously sweet jelly taste and odd doughy taste (was that supposed to be the toast?). I've read other reviews where people claimed it a coil clogger, but that was not my experience at all. Seemed to be reasonable coil life, though I ended up vaping this at lower watts to minimize the diet soda aftertaste. Even then, I ended up tossing it after half the 100ml bottle.
--Overwhelmingly sweet, then nasty diet soda aftertaste.
--No detectable butter flavor.
--No toast flavor, though did get an odd 'doughy' taste in the background.
--Though a physically 'thick' juice, not just horrible on coil choking (at least in the under-100 watt range).
--If you're immune to or basically don't mind artificial sweetener aftertastes, this might be a good sweet juice for those that like such.
Reviewed using: SMOK Alien between 40-75 watts with Baby Beast T8 coil, Clieto EXO with 0.2 coil, Clieto 120, or Vaporesso Cascade with SMOK M2 0.16 coil in adapter.
