I am fairly new to vaping, but tried a couple of suppliers concentrates, did nothing for me, now due to the info on this forum, got capella custard and choc fudge brownie. I do not know how I didnt drink it straight from the bottle when I smelled them, thet have a rich rich aroma. Now after keep smelling it for a week while it steeped, I have tried them today, I will never buy another concentrate other than Capella. I have been in heaven with the flavours, they do as they say on the bottle, its a damn good custard, and a fabulous choc fudge brownie. Used 15% for my mix. Thank you Capella.
