Yes, I ripped through a 15ml bottle quickly. It's very good. Why? I've been playing with it for a while, but I think this last version will need to steep to allow the graham cracker get it's full flavor. Not pulling your chain here, just trying to help and get some feedback because my taste buds are not like yours and vice verse. As a matter of fact I'm wondering if I may be light on the graham cracker at this point.
Have you been DIYing for a while? Make sure your specific on the ml and check your dropper to confirm if your using drops. I use a 35 drops per ml when using a Capellas Vanilla Custard bottle (for example). I guess maybe I feel like I'm trying to defend myself with your question but maybe I'm reading to deep into it with this... Sorry if so.......
Are all the other flavors 20 drops per ml except the vanilla custard?
