Good Afternoon! I'm new to this forum, and its so full of great info I wanted to thank everyone! With the costs of commercial juice skyrocketing at my local vape shots, I've been researching the DIY kits and finally ordered a starter kit to try it out. I decided to start easy and ordered premixed base. 30/70 at 3mg, which is what I was vaping in the commercial stuff I've been using. I made my first batch, starting at a small 10 mils. The flavor used was a simple berry blend included in the kit, at 10%. I'm noticing an unpleasant after taste that is hard to describe. Bitter, like the crappy tobacco flavors I've found in low end commercial stuff. I've also noticed this aftertaste in "pastry" style flavors before (churro, apple pie, etc...) I understand that some people enjoy this, but I really do not. My question is, where is this flavor originating from, and how can I get rid of it? Is it the nic base? I tend to think not, because my 30/70 berry flavor commercial juice I like doesn't have it. Or did I do something? not mix it well enough or not let it steep long enough? Any help is appreciated. Thanks!
