Sorry for the delay guys, been a crazy week at work! ok to answer your questions @kamophlaj, I used the grenadine, lemon, lemonade and strawberry that they've specifically developed for vapiong. I believe the site your on with the organic, extract and with or without diacetyl is not for vaping, at least it wasn't when I placed my order. Then their vaping site went down due to American FDA regulations and I haven't seen anything since. I agree with bigbluenose, email them and let them steer you. Err on the side of caution when using Capella super sweet, less is more. I went from 1 percent to 1 percent per 30 ml. Hope this helps!
Thanks @japhia42, I did contact them a d this was their reply for future reference.
"For vaping, most customers prefer to use our extracts as they are based in ethyl alcohol and will mix well with your PG or VG. What we refer to as our concentrates are very different than most other concentrates and will not work for vaping. All extracts are available without diacetyl. To view our selection of extracts without diacetyl, please check out the following link: https://www.naturesflavors.com/218-flavor-extract-without-diacetyl"
Thanks for the feedback and help.
