All About Rosin Jar Tech
From the Experts
What is Rosin Jar Tech?
Rosin jar tech, at its most basic description, is using a sealed jar to cure rosin. Curing rosin is the act of applying temperature and pressure differences or agitating the product to change the consistency, terpene (flavor) profile, and cannabinoid content. That’s right, you can change how your rosin tastes and the high it gives by curing.
How you cure is a personal choice and perfecting it will take some time and practice. As we mentioned, “Jar Tech” refers to using a sealed jar to cure your rosin. You can cure in a cold, room temperature, or hot environment. What temperature you cure at, how long you cure, and when you whip it up, is all up to you. These decisions will change the look, taste, and effects of your end product. We asked some experts in the field to give us some insight into their Jar Tech knowledge. Now we will get into how to cure using Jar Tech and why rosin-pressers use Jar Tech to cure.
How to Cure Using Rosin Jar Tech
To cure rosin using rosin jar tech, first, you will need rosin to cure, a sealable jar to cure in, a temperature controlled environment (hot, cold, room temperature, your choice), and a dab tool to stir (whip) the rosin (optional).
First, press your hash rosin or flower rosin as you normally would. Some people like to drip the rosin straight from the press into the jar. This can be accomplished by folding the parchment paper on the press to direct the flow of rosin coming from the press. You can also choose to collect the rosin from the parchment then put it into the jar. Once the press is finished, immediately seal the jar. It is important to keep the jar sealed to prevent certain terpenes from degrading.
Next, you can get creative with the cure. You can place the jar in either a hot, cold, or room temperature environment. Generally, the colder the environment, the longer a cure may take. There are no set temperatures to define “hot, cold, and room temperature”, but generally, ‘cold’ refers to about 50℉, ‘room temperature’ about 55℉ – 70℉, and ‘hot’ anywhere from 90℉ – 225℉.
How long you cure can be anywhere from 30 minutes to 14 days or more. Dan Lennon of Rocky Mountain Melts throws his sealed jars in the oven at 225℉ for about 30 minutes to an hour. Then he lets it sit on a heat pad for 14+ days. His goal is to produce a jam-like consistency.
Cold cures usually result in a more badder-like consistency. During the cure, terpenes may begin to separate from the rosin. These “terp puddles”, when mixed back into the rosin, can really change the flavor (for better or for worse). Heated cures may result in a more saucey consistency. It can also produce THCA diamonds separated from the terpenes. This may be referred to as “diamond mining”.
Each strain will yield different results when cured. GMO cold cure rosin can look, taste, and feel entirely different from GMO rosin with a heated cure. Drew Grissom of Kaya Farms in Southern California suggested taking an extra step and perfecting both a cold and a heated cure for a specific strain then mixing them together in your own ratio. All of the personal choices in a cure can leave you with a unique product that no one else has.
After the cure, many whip the rosin with your dab tool. Grissom states that “the main idea is that the post whip consistency is consistent throughout the entire jar”. When you whip, you are mixing back in the separated terpenes. How many times you whip and low long you work the product is up to you. Bryan Tornay of Heritage Hash Co. whips the product 2-3 times to achieve the consistency he wants.
Summary: How to Rosin Jar Tech
To cure your rosin using rosin jar tech you will need:
- Rosin to cure
- Sealable container (glass, stainless-steel, silicone)
- Temperature controlled environment (cold, room temperature, hot)
- Dab tool
The steps to cure rosin using jar tech are:
- Press flower or hash rosin
- Can drip the rosin straight from the rosin plates into a jar by folding the parchment paper to direct the flow of the rosin
- Can collect rosin from the parchment paper then place into the jar
- Seal the jar IMMEDIATELY
- Place the sealed jar in either a cold, room temperature, or hot environment
- Allow the rosin to sit in the jar until you see the desired results
- Cold cures and room temperature cure usually result in a more badder-like consistency with terpenes separating and forming puddles
- Hot cures may result in more sauce-like consistencies that may appear a bit grainy from the formation of THCA diamonds
- The cure can last anywhere from 30 minutes to 2 weeks
- (Optional) Use a dab tool to whip the rosin, creating a homogeneous consistency
Why Cure Using Rosin Jar Tech
So, why wait the extra time to cure your rosin when you could just smoke it fresh off the press? Well, no one is stopping you! Fresh press rosin is still rosin. Rosin pressing is an art form and a very personal experience; everyone presses in their own way. It makes sense that some people like to perfect their product to their standards by taking the extra steps to cure the rosin.
Dan from Rocky Mountain Melts prefers to cure rosin because it “brings out the terpene profile”. Drew from Kaya Farms prefers the consistency of cured rosin to fresh press and states the smoke is “usually smoother”. Bryan of Heritage Hash Co. cures his rosin because fresh press is too inconsistent with terpenes. One hit may be more or less flavorful than the next. By whipping the rosin after a cure to homogenize it, the terpenes and cannabinoids are consistent throughout the entire product. For this reason, if Bryan does use fresh press rosin, he carefully mixes it together then spreads it out into a sheet in hopes this will come close to homogenizing the product.
How you press your rosin and if/how you cure it is entirely up to you. Finding what works best for your likes will take some time and practice, but that is all part of the fun. The rosin community is filled with knowledgeable individuals like Dan, Drew, and Bryan who are more than happy to share tips and tricks. So, don’t be scared to ask for help!
