RH Mulberry Florentine probably goes down in history as one of the best blended flavours ever produced. I have been in the fortunate position to have the original replicated which wasnt cheap and reproduced just for me as a bespoke order. Its a combination of 3 different alcohols together with smells of summer fruits which totally enchants you. Other ingredients added are N butyric and low level fruit palatant, nothing else is needed!! 
Its basd on a High Alcohol High leakage which is the same principles as my Esters and PB1's which are both devasting to say the least. Produced in a subtle washed out yellow.
