Tannins
Fisetinidin can compose tannins.[1] The polymers are then called profisetinidin (Porter, 1992).[2]

gollark: The potatOS development model is to make something which kind of works and then to tack on extra bits without ever working out architecture but to periodically throw half of it out and redo it.
gollark: You could use the potatOS development model.
gollark: REAL PROGRAMMERS use assembly!!!
