Hey Kent,
Sorry about the oversight...I actually thought I answered you in an email, but I guess it wasnt you...There is no difference...When I first opened ALL my flavors were custom formulations...However some I cant duplicate exactly so I started carrying some of peoples favorites...If you notice the list of 20Ml bottles is dwindling away and thats because I am not filling any more 20Ml bottles...I am phasing out the 20Ml for 30Ml...So as a flavor dissapears from the 20ML size it re-appears in the 30...I hope that answers it for you...I am working on (among other things) a totally American Line of liquids...I have an American Company working on some flavors now for me...There are many flavors that alot of people like (RY4,555, etc) that I would like to carry in the American line, unfortunatley I just cant call up and order those flavorings YET!!!!! Thanks Kent for your interest in my products and your continued patronage...
