First Press Live Rosin is a mix-micron rosin concentrate. Whereas you’re smoking only 90u trichome heads in our Water Hash and Persy Rosin, our Live Rosin usually includes a full spectrum of water hash refined to dabbable oil. However, some of our 90u batches that do not meet our Persy qualification but still meet our quality standards are sold as Live Rosin. Rarely, you will also see a more affordable Second Press.
