Hash rosin and live rosin are both solventless, but they start with different materials. Hash rosin comes from pressed hash (usually dry sift or bubble hash), while live rosin comes straight from fresh-frozen flower. Live rosin has a brighter, fresher flavor, while hash rosin tends to be deeper and more earthy. At Binoid, we use fresh-frozen flower to make sure our rosin is terpene-rich and vibrant.
