Review of RY4 Double Flavor-TFA:

Great flavor ! I'm new to diy so I haven't mixed but 6/8 simple recipes yet but so far Tfa's RY4 Double has been my best flavor so far after a 2 week steep . I only bought 10 ml to try and mixed it at 15% solo it was good at 15% . So that took like 4.5 mills of my 10 mill bottle so I mixed the next 30 mill bottle with the rest at 20% waiting on it to finish steeping . And am fixing to order more larger bottle this time . But excellent flavor so far think I'll add some cream to my next batch .
