I have tried Gremlins, Grants, CLS, and Big Willies. By far my favorite is Grants, but Gremlins is very good as well even though it is quite different. Gremlins is a little sweeter and less eggy for me, but grants is very complex I can definitely taste the egg..which is something I want to taste in a custard.
Big willies just isn't doing it for me. It has been steeping for 2 weeks and is still a bit on the clear side. Should it be getting darker? Maybe I just haven't let it steep long enough, but the shipping is is amazing and Willie is great to deal with.
CLS is ok, but not as flavorful as the other three. But again, he is a great person to do business with.
Just so you all know vapourart.com has some GVC, just ordered 100ml.
