LorAnn's has a butterscotch flavoring. No idea how good it is to DIY it as it sits. Most people add ethyl maltol and even some Sucralose (get a free sample here:
EZ-Sweetz® Free Sample ) to the flavorings when doing DIY, check out that portion of the forum for more info. on making LorAnn's and other flavorings good). Also, Capella's may have a butterscotch flavoring.
Check out FreedomSmokeUSA, (Tucson) since their butterscotch and Hopscotch flavoring (from FlavourArt, Italy) and mixed liquids have gotten some fans talking about it. I have some butterrum from a few companies and it is pretty tasty (very butterscotch like).
Also, there was someone on the classifieds selling FSU liquid that had hopscotch and some others. Might see if it is left.
