I feel your pain. The old CashCap was my addiction for about 6 months during 2009... the aroma, the flavor!
THEN they changed the recipe (or their supplier, who knows) right before I put in a huge order. It wasn't even close (and had an odd red color). I sent all the CashCrap back. Later they put a disclaimer on their website that it wasn't the same (though never did admit on ECF that it was different). Don't know about today's version (Curtis' Coffee) but can't imagine it is even close and may just be the red 2nd version stuff renamed (anyone??). I refused to
buy anything from them after the odd way they handled the change in recipe.
I also have about 2 ml left of the original honey/milky/cinnamon/coffee goodness it and I should just grab a nice drink and vape it up and enjoy the last of it (and then weep a little)!
Wish I knew a recipe and I hope someone comes up with one.
However, for a very close liquid that is already made: A good
vaping bud (and also former CashCap addict) found that the Espresso from Backwoods Brew is CashCap like awesome (I haven't tried it yet, but I'd trust her taste as she's tried every coffee or cappuccino flavor out there). She just told me about it the other day. Maybe give a small bottle a try? I plan to soon.
