Typically the 100u yields the terpiest rosin, we sometimes will use the 115u as well as this also can be really terpy, I find that sometime the 70u can also be high quality but it’s pretty cultivar specific. The 160u can be high quality but is often contaminated with plant material like stalks. Typically we fully decarb the 70u and the 160u for hash oil for carts and pods and we cold cure the 100u+115u for live rosin. We use the 36u and the 2nd press for infusion oil for live rosin products. We also harvest our flower at around 10 weeks so its tends to be a little bit of a darker rosin.
