What Is The Difference Between Solvent And Solventless Concentrates?
The single most important distinction in the concentrate category is solvent versus solventless extraction. Solvent extraction uses butane, propane, ethanol, or supercritical CO2 to dissolve cannabinoids and terpenes out of the plant material, then evaporates the solvent off, leaving the concentrated extract behind. The process requires post-extraction purging to drive residual solvent levels below action limits and the COA confirms that purge. Solventless extraction uses only mechanical force, water, ice, heat, and pressure to separate the trichomes (the resinous structures that hold the cannabinoid and terpene fraction) from the plant material. No solvent is ever introduced, no purge is needed, and the residual-solvent question does not exist.
Solventless concentrates command a price premium because the process is more labor-intensive and the yield per pound of input biomass is lower. Olio's Straw Jelly Cold Cure Rosin 1g at 63.71 percent, Pump Up The Jam Cold Cure Live Rosin 1g at 66.34 percent, and Jelly Roller Cold Cure Live Rosin 1g at 60.71 percent run cold-cure live rosin, the most labor-intensive solventless format on our shelf. Umamii's Cold Cure Live Rosin Private Reserve Strawberry Guava 1g at 77.6 percent sits at the upper end of cold-cure pricing. Circle Hill's Live Rosin Dulce De Uva 2g at 75.89 percent runs the larger-format premium tier. Hudson Cannabis's Full Moon Solventless Hash Coin 1g at 56.96 percent represents the ice-water hash format from the Hudson Valley.
Solvent extraction produces concentrates with lower per-gram cost and often higher cannabinoid percentages because the solvent extracts more efficiently than mechanical separation. MFNY's Sour Diesel Live Resin Badder 1g at 63.45 percent runs hydrocarbon (butane or propane) live-resin extraction. Blotter's Diamond Powder 1g at 91 percent runs the diamond-recovery process described below. #HASH's Budder line, GG#4 at 63.53 percent, Angie at 72.38 percent, Papaya Juice at 78.95 percent, Sour Fuel at 75.44 percent, Cookie Kush at 75.78 percent, and the Crumble line including Purple Sunset at 78.43 percent and Burnout Cookies at 81.23 percent, all run butane-hash-oil (BHO) extraction with the consistency varied by post-extraction processing temperature and agitation.
What Is The Full Concentrate Taxonomy You Will Find In A New York Dispensary?
Hash, also called hashish, is the oldest concentrate format and the simplest. Trichomes, the resinous glands on cannabis flower, are separated from the plant material and pressed into a sticky resin or solid block. Three methods produce hash. Dry-sift uses mechanical sieving through screens. Ice-water hash washes trichomes in ice water and collects them through micron-graded bubble bags. Traditional charas is hand-rolled fresh-plant resin (rare in NYS retail because the production method does not scale into licensed operations easily). NYS retail hash sits typically in the 40 to 65 percent total cannabinoid range with full terpene preservation. Hudson Cannabis's Hash Coin is the current ice-water hash on the Chelsea shelf.
Rosin is solventless extract made by applying heat and pressure to cannabis flower, kief, or hash. Live rosin specifically refers to rosin pressed from ice-water hash that was made from flash-frozen cannabis. The flash-freeze preserves volatile terpenes that the standard drying and curing process degrades. Live rosin is the most labor-intensive solventless format, the highest terpene preservation, and the highest-end concentrate available in licensed retail. Cold-cure rosin is rosin that has been allowed to cure at low temperature, which transforms the texture into a stable, easy-to-handle consistency. Cold-cure live rosin (Olio's Pump Up The Jam, Umamii's Private Reserve Strawberry Guava) sits at the premium end of the solventless tier.
Live resin is solvent-extracted concentrate from flash-frozen cannabis using butane or propane in a closed-loop hydrocarbon extraction system. Live resin preserves terpenes well, better than cured-resin extraction, though not as cleanly as solventless live rosin. The residual-solvent question is addressed by the COA, and NYS regulation requires that residual solvents fall below specific parts-per-million action limits to clear retail. Live resin sits in the 60 to 90 percent cannabinoid range. MFNY's Sour Diesel Live Resin Badder is the current Chelsea example.
Budder, shatter, wax, crumble, and badder are variations on BHO consistencies, the visual texture varies but the underlying extraction is butane or propane. Budder is whipped to a buttery consistency. Shatter is left to cool flat, producing a glass-like brittle texture. Wax is opaque and creamy. Crumble is dry and granular. Badder sits between budder and wax. The consistency reflects post-extraction processing temperature and agitation, the cannabinoid content is similar across the variants (typically 70 to 85 percent). #HASH's budder and crumble lines on the Chelsea wall span this range.
THCa diamonds and diamond powder represent the most refined concentrate category. Crystallized THCa (tetrahydrocannabinolic acid, the acidic precursor to THC) is recovered from BHO or rosin extraction processes by allowing the extract to crystallize over time under controlled conditions. The crystals are nearly pure THCa, 90 percent plus by weight. When heated during consumption, the THCa decarboxylates into active THC. Diamonds are typically sold suspended in a terpene-rich "sauce," and the combination is called "diamonds and sauce." Blotter's Diamond Powder 1g at 91 percent is the in-stock pure-diamond format.
What Equipment Do You Need To Consume Concentrates?
Most concentrates require a dab rig, a specialized water pipe with a quartz, ceramic, or titanium "nail" or "banger" that is heated and then loaded with concentrate, which vaporizes off the heated surface. The user inhales the vapor through the water pipe's water-filtered mouthpiece. Electronic dab rigs (e-rigs) are battery-powered alternatives that control nail temperature electronically, removing the torch-and-timer step from the dabbing process. Puffco's Peak Pro is the dominant e-rig in the consumer market and the model most concentrate customers ask about at the counter.
A concentrate vape cartridge, dab-style with thicker concentrate viscosity, bridges the cart and dab-rig categories for users who want concentrate-tier potency without the rig setup. Live rosin cartridges (Ayrloom's Cereal Milk live rosin cart, for example, sits in our vape case rather than the concentrate case but contains the same source material as the rosin jars) deliver the solventless live rosin experience in a metered single-pull format. For customers who want to try a concentrate-tier extract without the rig investment, the cartridge is the path.
Dab tools (also called dabbers) are small metal or quartz utensils for transferring concentrate from the jar to the heated nail. Carb caps regulate airflow over the heated surface for more efficient vaporization. Terp pearls (small spherical inserts that sit inside the banger) increase surface contact between the concentrate and the heated nail. We sell the accessory tier at both counters.
What Temperature Should You Dab At?
Dab temperature is the single most consequential variable in the concentrate experience after dose size. Low-temperature dabs, in the 450 to 550 degrees Fahrenheit range (232 to 288 degrees Celsius), preserve terpenes, produce smaller vapor cloud, smoother flavor, and a more nuanced effect. The terpene profile you paid the premium for in a live rosin lands on the palate. High-temperature dabs (650 degrees Fahrenheit plus) produce bigger cloud, harsher draw, faster cannabinoid extraction, but burn off the delicate terpenes and increase respiratory irritation.
For live rosin and live resin, the low-temperature setting is the recommendation, the entire point of paying the premium for terpene preservation is to taste the terpenes. For older concentrates that have lost some terpene fraction, or for distillate-based concentrate products with botanical-terpene reblends, higher temperatures may be appropriate. The Puffco Peak Pro's "Standard" preset (520 degrees Fahrenheit) sits in the low-temp window. The "Boost" preset (565 degrees Fahrenheit) sits at the upper edge of terpene-preserving range. The "High" preset (600 degrees Fahrenheit) crosses into terpene-degradation territory for premium solventless product.
How Does A Concentrate Dose Compare To A Joint?
A 0.1g dab of 80 percent THC live rosin delivers approximately 80mg of THC into the lungs in a single inhalation. A 0.5g pre-roll of 22 percent THC flower delivers approximately 110mg of THC into the lungs across a 15-minute burn time spread over 8 to 12 puffs. The concentrate delivers comparable cannabinoid load in a single deep inhalation versus the flower's distributed dose curve.
This concentration is why the format is for experienced users and why a misjudged dab is the fastest route to overstimulation in adult-use cannabis. The per-hit dose is dramatically higher than flower or carts, and the timing window between "took the dab" and "feeling the full effect" is essentially zero, you do not get the 60-to-90-minute warning system an edible provides. For a first concentrate session, a rice-grain-sized dab (approximately 0.025g) at low temperature (450 to 500 degrees Fahrenheit) is the appropriate starting size. Scale up only after a first session has produced a known baseline.
Why Does Cold-Cure Rosin Cost More Than Standard Rosin?
Cold-cure live rosin requires the rosin press output to cure under controlled cold conditions for 24 to 72 hours after pressing, during which the texture transforms into a stable, easier-to-handle consistency and the terpene profile re-integrates with the cannabinoid fraction. The cold-cure step adds time and storage cost to the production cycle. The result is a concentrate that doses more easily on a dab tool, holds shape at room temperature, and tastes more cohesive than fresh-press rosin that has not had time to cure. Olio's Cold Cure Live Rosin line and Umamii's Cold Cure Live Rosin Private Reserve sit in this premium-cured tier.
Frequently Asked Questions
What is the strongest concentrate you carry?
Blotter's Diamond Powder 1g at 91 percent total cannabinoid content sits at the top of the Chelsea concentrate case. #HASH's Crumble Burnout Cookies at 81.23 percent and Crumble Purple Sunset at 78.43 percent represent the BHO crumble tier. Umamii's Cold Cure Live Rosin Private Reserve Strawberry Guava at 77.6 percent and #HASH's Papaya Juice Budder at 78.95 percent represent the top of the live rosin and budder tiers.
Do I need a dab rig to use concentrates?
For most concentrates, yes. Electronic dab rigs (e-rigs) like the Puffco Peak Pro are an easier alternative with electronic temperature control. Concentrate vape cartridges are a no-equipment alternative that delivers concentrate-tier potency in a metered single-pull format.
What is the difference between live rosin and live resin?
Live rosin is solventless, made by pressing ice-water hash from flash-frozen cannabis under heat and pressure. Live resin is solvent-extracted from flash-frozen cannabis using butane or propane in a closed-loop hydrocarbon system. Both start from flash-frozen material to preserve terpenes. Live rosin is more expensive and carries no residual-solvent question.
How much concentrate equals a joint?
A 0.1g dab of 80 percent THC live rosin delivers approximately 80mg of THC in a single inhalation, comparable to the total cannabinoid load of a 0.5g 22 percent THC pre-roll spread across a 15-minute burn time. The concentrate delivers the dose in a single hit rather than across a distributed session.
What is the safest concentrate for a first-time user?
A rice-grain-sized dab (approximately 0.025g) of a quality live rosin or ice-water hash at low temperature (450 to 500 degrees Fahrenheit). Alternatively, a concentrate vape cartridge, which delivers concentrate-tier potency in a metered single-pull format without the rig setup or the dose-judgment risk of free-form dabbing.
Are concentrates tested for residual solvents?
Yes. NYS regulation requires residual-solvent testing on every solvent-extracted concentrate, action limits are set per OCM standards (typically parts-per-million for butane, propane, ethanol, hexane). Solventless concentrates (rosin, ice-water hash, cold-cure rosin) have no residual solvent by extraction design and the COA confirms the solventless attestation.
What is cold-cure live rosin and why does it cost more?
Cold-cure live rosin is rosin pressed from ice-water hash made from flash-frozen cannabis, then cured under controlled cold conditions for 24 to 72 hours after pressing. The cure step adds time and storage cost and produces a more stable, terpene-cohesive concentrate. Olio and Umamii's cold-cure lines sit at the premium tier on the Chelsea shelf.
What are "diamonds and sauce"?
THCa diamonds are crystallized cannabinoid precursor (the acidic form that converts to active THC when heated) recovered from BHO or rosin extraction. The diamonds are typically packaged with a terpene-rich liquid "sauce" surrounding them. The combination delivers very high cannabinoid potency with terpene-driven character.
What is a "Hash Coin"?
Hudson Cannabis's Full Moon Solventless Hash Coin is a 1g pressed-hash format produced by ice-water trichome separation and pressing into a coin-shaped puck. The format is functionally hashish, the coin shape is the brand's presentation. Tests at 56.96 percent on the current lot.
Do you sell concentrates by the half-gram?
Some SKUs ship in 0.5g formats and most in 1g. Circle Hill's Live Rosin Dulce De Uva ships in 2g. The format size depends on the cultivator and the production batch.
Can a concentrate vape cart replace a dab rig?
Functionally, for most consumption occasions, yes. The cartridge delivers concentrate-tier potency in a metered single-pull format without the rig, torch, or temperature-judgment step. The trade-off is less dose flexibility per hit and slightly less terpene presence than a low-temperature dab of premium live rosin.
Is solventless concentrate safer than solvent-extracted concentrate?
Both are safe when produced under NYS regulation, the COA confirms residual solvent levels below action limits for solvent-extracted product. Solventless concentrates avoid the residual-solvent question entirely because no solvent is ever introduced. For customers who specifically want to remove that variable from the equation, solventless is the answer.

Cannabis Edibles At The Alchemy, Dosed To The Milligram, Onset In 60 To 90 Minutes, Peak Around Two Hours
The single most common mistake with edibles is impatience. A 10mg gummy taken at 7:00 PM does not hit at 7:15. It hits between 7:45 and 8:30, peaks somewhere between 8:30 and 9:30, and tapers across the following 3 to 6 hours. The customer who takes a second 10mg piece at 7:30 because "the first one didn't work" is the customer who ends up uncomfortably high at 9:00 PM. This is the conversation our counter team has more often than any other, and we will have it with you too. There is no judgment in it. The timing is counterintuitive coming from any other consumption format, and the cost of overshooting is hours of discomfort, not minutes.

Cannabis Vapes At The Alchemy, Live Rosin, Live Resin, Distillate, And Disposables, Every Cart Tested For Vitamin E Acetate
The 2019 EVALI outbreak, the lung-injury cluster that hospitalized 2,807 patients across all 50 states and killed 68 according to CDC tracking, was traced overwhelmingly to vitamin E acetate cutting agents in unlicensed THC vape cartridges. That outbreak reshaped how every licensed cannabis market handles vape safety testing. New York's MRTA framework, operationalized through OCM regulation, requires every cartridge sold in licensed adult-use retail to pass a Certificate of Analysis that explicitly tests for vitamin E acetate, residual solvents (butane, propane, ethanol, hexane), heavy metals (lead, cadmium, arsenic, mercury), pesticide residue across the OCM banned list, microbial contamination, and cannabinoid potency. The testing is performed by NYS-approved third-party laboratories independent of the manufacturer, and the COA is QR-accessible on every package on the Alchemy shelf.
pre rolls nyc
Pre-Rolls At The Alchemy, Single Joints, Multi-Packs, Infused, And Hash-Holes Across NYS Craft Producers
A pre-rolled joint is the simplest cannabis purchase in a licensed dispensary, ready to smoke, portable, no grinder, no paper, no roll. It is also the most consumption-occasion-flexible format on our shelf. A single 0.5g pre-roll fits in a coat pocket and works for a walk along the High Line. A 5-pack of 0.35g mini pre-rolls splits across an evening with friends. A 1g infused pre-roll, a joint laced with hash, kief, or concentrate, is a stronger experience for the experienced regular. A hash-hole, a joint with a center core of pressed hash, sits at the most potent end of the pre-roll category. We carry the full range across roughly 30 pre-roll SKUs from 14 New York State licensed craft producers on the current menu.
