Solventless concentrates are always popular among cannabis fans.
It offers pure flavor, without the need for chemicals to extract. Unlike concentrates that use solvents for extracting, products like dry sift and bubble hash rely on mechanical processes to separate the trichomes that hold the flavor and potency, resulting in a more natural product, without the harshness of plant materials.
Dry sift and bubble hash are popular and similar because they don’t use solvents to extract. However, there are differences between the two concentrates.
Of course, the question one might ask right now is, “Which is better?”
Let’s dive deeper into the characteristics of each concentrate.
What Is Dry Sift Hash?
Dry sift hash is a solventless concentrate made by mechanically separating trichomes from dried cannabis plant material using a series of fine-mesh screens. This process allows hash makers to collect the resin glands while leaving behind unwanted plant material.
Effective dry sifting relies on the different micron ratings of the screens used in sifting the plant material. As trichomes come in different sizes, the lower the micron rating, or the finer the screen is, the purer the trichomes collected.
Many growers and hash makers lean towards dry sifting because it maximizes the yield from any plant material, including trims. The sifted resin can be used for hand-pressed hash, sprinkled over flowers to boost potency, or pressed into rosin. Unlike bubble hash, dry sift doesn’t require drying time, making it accessible right after sifting.
Benefits of Dry Sift
Terpenes Preservation
Losses are minimized since dry sift doesn’t come in contact with water, resulting in flavorful hash.
Easier to Store
Since dry sift is dried or cured, having a lower moisture content reduces the risks of molds.
Simple Setup
You only need a set of mesh screens, making it a cost-efficient extraction method.

Problems with Dry Sift
Labor-Intensive Process
Requires time, patience, and a precise technique to achieve quality results.
Higher Risk of Contaminants
Plant material can easily mix into the final product if not carefully refined.
Additional Steps for Full-Melt Quality
Achieving full-melt potential requires extra refinement techniques.
Achieving Full Melt Quality

One challenge of dry sift hash is getting full-melt quality concentrates.But that doesn’t mean you can’t get full-melt quality. It is possible to use static tech, wherein static electricity purifies dry sift hash. An electrostatic charge separates the trichome heads from unwanted plant materials. Resin and plant contaminants have different charges, and static may be applied to refine the dry sift.
There are two safe ways to refine dry sift:
-
Stretch a sheet of parchment paper over a hard edge and sweep across the dry sift on a screen, attracting trichome heads away from the plant matter.
-
Lightly swirl the dry sift in a smooth, clean bowl, wherein the trichome heads will cling to the sides of the bowl due to static attraction.
For best results, static tech should be done in a cold environment, as cooler temperatures keep trichomes brittle and easier to separate, turning ordinary dry sift into full-melt quality.
What Is Bubble Hash?
Bubble hash is another type of solventless cannabis concentrate made using an ice water bath for extracting trichomes from the plant material. As trichomes are denser than water, they easily break apart from the plant material during extraction.
Extracting bubble hash involves:
-
Agitating cannabis material in ice water to allow the trichomes to snap from the plant material
-
Filtering the mixture using bubble bags to separate the trichomes by size.
-
Collecting and drying the hash by air or freeze drying to prevent mold.
Bubble hash is graded on a six-star rating system, with five- and six-star bubble hash being in the top tier, known for melting when heated. Likewise, the starting material for bubble hash is fresh frozen, unlike dry sift, which uses dried or cured plant material.
Benefits of Bubble Hash
Strong Flavor and Potency
Delivers rich terpene profiles and high potency, leaving minimal residue when dabbed.
Exceptional Purity
Water filtration effectively removes plant material, resulting in a cleaner concentrate.
Superior Full-Melt Potential
The multi-stage filtration system ensures a refined product that melts more completely when heated.

Cons of Bubble Hash
Requires Specialized Equipment
Needs bubble hash bags, an ice water bath, a collection container, and a controlled drying space.
Extended Drying Time
Must be thoroughly dried to prevent mold; freeze dryers speed up the process but add to costs.
Terpene Loss Risk
Overexposure to water can strip away valuable terpenes, affecting flavor and aroma.
While we have listed the differences between the two, when it comes to preparation, let’s look at the fine details of how dry sift and bubble hash differ.
Factor |
Dry Sift |
Bubble Hash |
Purity |
Can contain more contaminants unless well-refined using static tech. |
Generally purer due to water separation |
Yield |
Often lower unless done in bulk |
Higher yields but vary by technique |
Ease of Process |
Simple but time-consuming |
Requires more setup but faster results, but takes time to dry. |
Equipment Needed |

Dry Sift or Bubble Hash: Which one should you choose?
Dry sift and bubble hash lean towards different concentrate fans. They both have advantages and disadvantages, depending on the end-user’s preference.
Choose Dry Sift if you:
-
Want better terpene preservation and the most natural flavor profile.
-
Prefer a simple process that is ready to use after extraction.
-
don’t mind the extra work when refining to achieve full melt quality
-
Plan to use the sifted trichomes for sprinkling on flowers, pressing into rosin, or making hand-rolled hash.
Choose Bubble Hash If:
-
You want a more refined product after extraction
-
When processed correctly, you’re aiming for a higher-melting hash that can reach five- or six-star full-melt quality.
-
You don’t mind the extra equipment and drying time needed
-
You plan to press rosin and want better yields from your hash.
Final Thoughts
Both dry sift and bubble hash are great solventless extraction methods, each with its strengths. Ultimately, the best method depends on how you plan to enjoy the hash, which will be the deciding factor whether you need dry sift or bubble hash.
