Never tried the original, but this fits the description: "This is a regal blend of pinot noir grape and blackcurrant". I thought I'd like it. It's pretty good. Certainly not your ordinary vape. You could drop it to 2.5% and 1.5% and still have good flavor, I think. It's special enough that you should try it!
I was actually just shopping for FA's versions of the flavors as you sent that message lol. Im PG sensitive so that's why I stick with NF. Will pick up a bottle of each flavor and give it a whirl though. If I dont' vape too much with PG I'll be ok.
Fortunately Flavour Art is strong, so it's only 5% total flavoring, so you could do a 5/95 PG/VG ratio - I think it's still strong enough even though it's max VG :)
Finally!!! I have spent much time and money with other flavors trying to recreate this. I ordered FA version of grape and black currant and followed your recipe exactly. This is about 95% possibly 100% exact match. I whipped up a batch and did a quick steep by putting in a hot water bath. I vaped 100's of ml's of the real Catherine the Grape and this is the real deal !! Thanks so much for posting this recipe.
