My oldest recipe is based on TFA Creme De Menthe. Couple of years back I reduced the amount of flavoring in most of my recipes. Mostly that worked out fine. But recently on an impulse I mixed a bottle of CdeM with the original %. Tried it today after a good steep and it blew my head off. It was like the menthol blast you get from disposables. I vaped it like that for many years.
