Every producer has their own method of producing cannabis concentrates and some are certainly better than others. In order to get the high quality, terpene rich concentrates that have become the hallmark of BOSM Labs, we have developed our own five-point method for ensuring that our terpenes are protected at every stage of the extraction process, guaranteeing the best flavor for all of our customers.
Let’s take a closer look at the process.
Step 1: Gentle Harvest
Any good cannabis concentrate first and foremost relies on great starting product handled by skilled gardeners. To achieve this, at BOSM Labs we work with growers to ensure that they are harvesting their plants in accordance with our strict quality control standards so that the before the plant is even in our hands, we know that is being treated properly.

Step 2: Cryopreservation
What differentiates Live Resin from other forms of cannabis concentrate is that it is frozen immediately following harvest. This process stops the metabolic processes of the plant and prevents the degradation of plant material, and most specifically to our process terpenes. To do this, we use liquid nitrogen to flash freeze the whole plant at temperatures as low as -80 C. Since the freezing takes place at the site of harvest, we then use an Ultra-Cold freezer truck to transport the plant back to our lab where it is stored under similarly cold conditions until it is time for processing.
Step 3: Cryogenic Grinding
When it is time to prepare the plant product for processing, we begin by cryo-milling the whole plant that was frozen and delivered by the growers. This process involves simultaneously reducing all plant particles to equal size in a custom-built miller and freezing this plant particles uniformly with liquid nitrogen. This process ensures the solvent will be evenly distributed throughout plant material to capture all possible cannabinoids and terpenes that are present. Once the material is cryo-milled, it is ready for socking and extractions using our state-of- the-art ETS Modular Extraction Platform.
Step 4: Delicate Purge
One of the most common mistakes that people make when extracting is to rush the purging process with ovens that are set to high. This costly mistake ruins the terpene profile of the concentrate as they burn off. Instead, we set out ovens low enough that only the solvents will burn off while the terpenes are preserved. This process can take upwards of five days, but we feel that patience is rewarded with an exceptional product that properly represents the plant it came from.
Step 5: Protective Environment
The final aspect of the Five Point Terpene Protection Plan ensures the product is stored in a way that what comes out of the package the same as what came out of the ovens. Often Live Resin is stored at room temperature which can cause terpenes to evaporate as the concentrates wait to be sent to stores.
Instead, we store and package our entire line of products in a temperature controlled room with minimal human interaction to limit any variables that might degrade the taste and aroma until it is sent out to our customers.
