if you're into mixing your own juices, ive literally just mixed up a 5ml tester of capella's vanilla custard to test as a base line and been comparing to my GVC in my other dripper. its got the definite creaminess of gvc but lacks the sweetness, hopefully with a few drops of Ethyl maltol it should be a good GVC substitute for when Grant is out of stock. will mix up and find the right balance this week.
