What Is Bubble Hash Rosin?
Bubble hash rosin is a premium solventless concentrate made by pressing bubble hash under heat and pressure to extract rosin, a rich and potent oil. Since bubble hash is a highly refined concentrate, the rosin extracted is purer and more flavorful than rosin pressed directly from a flower.
The nice thing about bubble hash rosin is that it combines two of the best concentrates in the market. It captures the purity and potency of bubble hash while offering the smooth dabbable texture of rosin.
As a result, you can expect less plant matter and more trichomes, a stronger flavor, and smoother dabs.
How Bubble Hash Rosin Is Made
Bubble hash rosin is made by pressing the bubble hash with a pair of heated plates for a certain amount of time. When heat and pressure are applied, the rosin oozes out, dripping onto your collecting plate or paper.
Pressing bubble hash into rosin is an art. The process requires a careful balance of heat, pressure, and filtration to extract the most cannabinoid- and terpene-rich rosin while leaving behind unwanted plant materials.
Rosin extraction uses the principle of phase transition, where the right combination of heat and pressure allows the plant material to release cannabinoid and terpene-rich oils.
Micron Matters
One important element in extracting rosin from bubble hash is the micron size used for the bag filter. This determines how much plant material is filtered, which affects purity, consistency, and yield.
To help you understand which micron bag works best, here's a quick guide:
- 15 – 37µm: Best used for pressing high-quality, full-melt hash and produces the purest, terpene-rich rosin, while sacrificing yield.
- 37 – 90µm: A balance between purity and yield that works best for various grades of bubble hash.
- 90 – 120µm: Produces more yields, but may also have plant materials in the rosin.
Hash Rosin Pressing Parameters
The grade of your bubble hash determines the optimal micron, temperature, and press time. Use this reference when dialing in your press settings. For a deeper breakdown of how each variable affects output, see the rosin yield optimization guide.
Equipment You Need
Beyond the washing machine that produces your bubble hash, three pieces of pressing equipment have the biggest impact on rosin quality and yield:
- Rosin press (minimum 4-ton for hash): A dedicated press gives you precise temperature control and even platen pressure. Browse rosin presses to find the right tonnage for your batch size.
- Rosin filter bags (25-90µ for hash): Micron rating is the single biggest lever for purity versus yield. Stock a range of sizes from rosin filter bags so you can match the bag to the hash grade.
- Pre-press mold: A tight puck eliminates air gaps and prevents blowouts, especially with drier hash. Pre-press molds pay for themselves quickly in reduced waste and cleaner rosin.
Tools Needed for Pressing Bubble Hash
Before pressing bubble hash into rosin, you need a reliable way to extract the hash itself. Bubble hash washing machines like the Bubble Magic 5-Gallon Washing Machine (or the 20-Gallon version for larger batches) simplify the process by efficiently separating trichomes from plant material using ice water agitation. With the right micron filter bags, this machine allows you to extract high-quality resin in just 15 minutes.
The core component for extracting rosin is a rosin press, which applies heat and pressure to extract the rosin from bubble hash. There are different types of rosin presses in the market today, so let's look at your options:
Small-Scale Personal Use
For those starting out, a hair straightener can work for pressing small amounts but lacks the precision needed to extract efficiently. If you have a shop press, you can make your own rosin press using a pair of heating plates.
If you don't mind spending a little, you can opt for personal rosin presses like the Ju1ceBox.
Mid to Large-Scale Pressing
For production purposes, a manual or hydraulic press works fine when pressing bubble hash in ounces.
If you want more power and efficiency, a pneumatic or electric rosin press allows you to maximize each press. A 20-ton pneumatic or electric press is best for high-volume production.
Aside from the rosin press, you will also need:
- Rosin Bags
- Parchment Paper
- Cold plates or metal collection tools
- Vacuum-sealed glass jars
How to Press Bubble Hash into Rosin
Bubble hash rosin needs the right balance of heat, pressure, and filtration to get the best results.
1. Choose Micron Rating
To start pressing bubble hash, choose your micron rating based on your desired output. If you are unsure about which micron rating you need, experiment with different micron bags to see which gets the best result.
2. Load the Micron Bag
Fill the micron bag with bubble hash, up until 75% full, and half an inch thick. Distribute the bubble hash evenly inside the bag to ensure an even press. Consider using a double bag to prevent blowouts.
- If the hash is sticky or clumpy, gently form it into a small puck before inserting it into the bag.
- You can use a pre-press mold to keep the bubble hash compact and eliminate any air gaps.
- Lightly warm the mold using a heated press plate before pre-pressing.
3. Fold Parchment Paper
The next step is to fold the parchment paper using the directional flow method to ensure that the rosin flows away from the heat source. Place the micron bag with bubble hash inside the fold of the parchment paper and center it between the rosin press plates.
- Consider pre-heating by lightly applying pressure for a couple of seconds then releasing.
- Repeat this process several times until trichomes start melting.
4. Begin Bubble Hash Rosin Extraction
Once the trichomes start melting, you can begin the extraction with a low amount of pressure, then gradually increase it. Refer to the pressing parameters table above for recommended temperature and time ranges by hash grade. For tips on maximizing your output, the rosin yield optimization guide covers advanced techniques in detail.
5. Collect the Rosin
To collect the rosin, place the parchment paper on a cold plate to cool the rosin. Use a dab tool or rosin collection tool to scrape the rosin from the parchment paper. Transfer the rosin into a glass jar to cure and store in a cool, dark place to preserve terpenes.
Storage and Curing Bubble Hash Rosin
Proper curing and storage are crucial to preserve the flavor, potency, and stability of bubble hash rosin. Often, bubble hash is a product of fresh plant material, hence the need to cure it, like cannabis buds. Curing allows you to refine the texture, flavor, and cannabinoid profile for a premium quality product.
There are two ways of curing bubble hash rosin:
Jar Tech Method
The Jar Tech Method takes around 24-72 hours to cure the bubble hash. This works best for softer, sauce-like rosin. To use the Jar Tech Method:
- Place fresh-pressed rosin in a sealed glass jar while still warm.
- Store in a warm, dark area at around 85-100°F.
- Open the jar daily to "burp" it, releasing unwanted gases.
Cold Curing
Cold curing takes more time and can last as long as two weeks, but prolongs the shelf life of your bubble hash rosin. This works best for thicker rosin. To use the Cold Curing Method:
- Place rosin in a sealed glass jar immediately after pressing.
- Store in a cool, dark place at 50-60°F.
- After a few days, open and stir the rosin gently to encourage nucleation.
Conclusion
Bubble hash rosin is one of the purest, most flavorful, and potent solventless cannabis concentrates. From the detaching of trichome heads to the pressing to extract rosin, bubble hash rosin maintains the solventless characteristic, offering stronger flavors and potency.
