What is Hash?

Hash, or hashish, is a highly potent cannabis concentrate derived from the plant's trichomes, the tiny, hair-like structures found on its surface, through mechanical means. Revered for its medicinal and spiritual benefits for centuries, hash traces its roots back to ancient Central Asia and the Indian subcontinent.

The properties of hash can vary greatly, influenced by factors such as the cannabis strain and extraction method employed. These variations affect attributes like color, texture, flavor, and potency, resulting in products that range from crumbly and dry to sticky and pliable. Notable types of hash include finger hash, powdery kief, and hand-rolled bricks, each offering a unique experience for cannabis enthusiasts.

What is Hash Made Of, & How is Hash Made?

Hash can be produced using a range of methods, but the general idea is to extract the trichomes from the surface of the plant. Depending on the method used, this process can be as simple as separating the trichomes by hand or as complex as using chemical solvents to extract the resin. While the fundamental principles of hash-making have remained the same for centuries, advances in technology and new techniques have led to various methods for producing high-quality hash. In the following section, we will explore some of the most popular ways of making hash.

  • Dry sift/sieving: Dry sift hash is produced by separating resin glands from cannabis flowers using mesh screens. By agitating the flowers against the screen, the dried glands break off and the trichomes pass through. The result is a powdery substance that can be mixed into a joint or pressed into traditional hash or rosin.
  • Ice water extraction: This method creates ice water hash, also known as bubble hash. Cannabis buds are immersed in ice water, which freezes the trichomes. Agitation then breaks off the trichomes, which are filtered through mesh bags. The collected resin is dried and transformed into full melt, or six-star hash, suitable for dabbing with a vapor rig. Lower-quality products may be pressed into rosin.
  • Hand-rubbed: As the oldest and most prevalent technique for making hash, hand-rubbing involves rubbing cannabis plants to gather the trichomes.
  • Solvent-based extraction: This extraction method uses chemicals to isolate trichomes from the rest of the cannabis plant. A popular approach is butane extraction, which yields butane hash oil by soaking plant material in butane and purging it after the extraction process is complete.
Most popular ways to consume hash: smoking, vaping, edibles

There are many ways to consume hash, and the method you choose ultimately depends on your personal preference. Some of the most popular methods for enjoying hash are:

  • Smoking: You can smoke hash in a bong or a pipe or simply roll it up in a joint along with cannabis flower.
  • Vaping: Vaporizers provide a smoother experience by heating hash without combustion, releasing its active compounds in a less harsh form.
  • Edibles: For a different and potentially longer-lasting experience, infuse hash into butter or oil and then use it in various recipes, such as brownies, cookies, or even savory dishes.

What is Rosin?

Introduced in the early 2010s, rosin emerged as an innovative method for producing cannabis concentrates. While hash has a lengthy historical background, rosin was devised as a solvent-free alternative. Made by applying heat and pressure to cannabis flowers or other forms of cannabis such as kief and hash, it has gained popularity in recent years as a cleaner and purer product.

Similar to hash, rosin’s properties can be influenced by the cannabis strain it is created from and its extraction methods. These elements contribute to a diverse array of product outcomes, from glass-like shatter to smooth, buttery consistencies. Among the notable types of rosin are live rosin and solventless hash rosin.

As we've mentioned, rosin production relies on the use of heat and pressure. Now, let's explore the various types of rosin, their manufacturing techniques, and distinct features.

  • Flower rosin: Flower rosin is made by pressing high-quality, well-cured cannabis buds using heat and pressure. As it is derived directly from cannabis flowers, flower rosin retains the unique flavors and terpene profiles of the strain used. It is often less potent than other types of rosin due to the lower concentration of trichomes in comparison to kief or hash.
  • Kief rosin: Kief rosin is produced by pressing sifted trichomes or kief collected from the cannabis plant. It typically offers a more potent product due to the higher concentration of trichomes. It generally has a cleaner flavor profile than flower rosin as well, as it contains less plant material.
  • Hash rosin: Hash rosin is derived by pressing compressed trichomes or hash using heat and pressure. It combines the traditional appeal of hash with the modern, solvent-free extraction method. Hash rosin typically has a higher potency than flower rosin and a more refined flavor profile, as it is made from concentrated trichomes with minimal plant material.
  • Live rosin: Live rosin is a premium type of rosin extracted from fresh, frozen cannabis plants that are immediately processed after harvest. This process preserves the plant's full range of cannabinoids and terpenes, resulting in a concentrate that retains the unique flavors, aromas, and effects of the cannabis strain to the fullest.
Most popular ways to consume rosin: smoking, dabbing, vaping, edibles

Rosin is a versatile cannabis concentrate that can be consumed in a variety of ways. Each method offers a unique experience in terms of flavor, intensity, and duration of effects. Some popular ways to consume rosin include:

  • Smoking: Like hash, rosin can be smoked in a bong or pipe. It can also be spread thin onto rolling paper and consumed in the form of a joint.
  • Dabbing: Dabbing is one of the most popular methods for consuming rosin. Using an e-rig or dab rig specifically designed for concentrates, place a small amount of rosin on the heated nail or banger. Inhale the vapor for a potent and flavorful experience.
  • Vaping: Rosin can be used in vape pens or other vaporizers compatible with concentrates.
  • Edibles: After heating the rosin to activate its cannabinoids, it can be used in a range of recipes.
