I recreated this concentrate as a humble attempt to clone RY4 Double (TPA). After several tests, the result is a nice RY4 interpretaton ,both in terms of the flavor profile and overall balance. A good alternative for anyone who wants to make their own clone concentrate.
Suggested diluition:
Start at 20% and increase the concentration if it is too weak. Decrease the concentration if it is too strong.

Example:
For 10 ml at 20%: use 2 ml of concentrate and 8 ml of base.

If you have the pure molecules, use these percentages:
Ethyl Maltol — 11.50%
Methyl Cyclopentenolone (Cyclotene) — 8.75%
Vanillin — 0.75%
Distilled Water - 1%
PG — 78.00%
Suggested dilution: try at 8-10%
Hope you Enjoy , Ugo 👋🏻 🇮🇹
