COLD CURE ROSIN Peachy Hash & Co.’s Cold-Cure Rosin Badders pop with flavor. Curing the fresh pressed rosin for a number of days before whipping and stirring the final texture creates a homogenous and shelf-stable style of hash rosin. Our cold-cures carry a wet & gleaming look from the transparent terpenes gleaming on the surface. This style of rosin should be kept cold, but will not undergo significant changes at room temperature.
