So much of the flower rosin pressing process is trial and error. We can give you all of the tips and tricks in the world, but at the end of the day, you really just have to play around with your Rosinbomb until you find a process and end product that work for you. Because so many people enjoy so many different kinds of concentrate, there is never going to be one “right” way to extract rosin.
One of the main components of your process is temperature, and the level of heat at which you set your machine can greatly affect the yield and consistency of your rosin. While heat and pressure are what turns those precious trichomes into rich oily rosin, this isn’t a panini press and we don’t want grill marks.
There are some benefits to cold pressing, and if you’re looking for a thicker, more budder-like consistency to your rosin, setting your Rosinbomb somewhere between 150 and 180 degrees Fahrenheit will likely get you the results you seek. Remember, though, that the lower the temperature, the lower the yield. With lower temperatures, you’ll achieve the highest level of terpene retention, ensuring your rosin is packed with flavor, there just won’t be as much of it in the end. As you increase your temperature setting, you’ll see more rosin ooze out the sides of the plates, with a more liquidy oil texture. Higher temperatures will net you more rosin but you need to be careful not to go too high or you’ll burn out your source material and your rosin will be void of the valuable terpenes we want to preserve. The sweet spot for shatter-like rosin that maintains significant flavor is around 195 to 205 degrees Fahrenheit. Anything in the 210 to 220 degree range will probably give you your highest yield, but you may not be happy with the results once you dab it.
Aside from temperature, the timing is also key to this process. If you’re cold-pressing, you can leave your plates pressed down for longer without worrying about burning terpenes. If you’re pressing at sub-170 degrees, feel free to time your press around 3 to 5 minutes, lowering the amount of time as you raise your temperatures.
Personally, I like mixing it up with temperature and time and consistency. Sometimes, I’ll start out with lower temperature and more time, producing a thicker rosin, then I’ll press the same pack again at a higher temperature for about 60 seconds to squeeze out any remaining oil. There will be two different looking oils on your parchment paper when you pull it from the Rosinbomb, but I like to mix them up on the dab tool and see how it all tastes together.
Take notes as you go so you can really dial in your process and fine tune it to reach your desired end result.
