My first DIY batch was done today. Capella - Watermelon 17%, steeped for 3 days, 70/30, 24mgs. Is all OK, very easy to vape, but leaves just a touch of bitter quasi-fruity aftertaste, but this is likely merely subjective. The flavor is not strong at all, if anything a bit on the weak side, but that's OK. What suggestions do you have to address this slight bitterness that I could add? I have tried to add a couple TFA Ethyl Maltol drops, but that creates yet another taste and does not seem to make much difference other than to add a touch of sweetness. All my stuff is Capella. Any advices on this would be greatly appreciated.
