New Live Rosin Drops

The Alchemy live rosin shelf currently includes the following drops, with the menu refreshing as new lots arrive:

Mfused single-cultivar live rosin grams. Single-cultivar live rosin in 1 g format from multiple cultivars. Each lot specifies the source cultivar and the resulting terpene profile. Featured cultivars rotate weekly.

Mfused live rosin cartridges. Solventless live rosin in 0.5 g and 1 g cartridge formats, compatible with standard 510-thread batteries. Cultivar-specific terpene profiles preserved through the pressing and cartridge-fill process.

Mfused live rosin disposable vapes. Solventless live rosin in single-use disposable vape pens. 0.3 g and 0.5 g formats.

Mfused live rosin gummies. Solventless live rosin infused into gummy edibles. 5 mg and 10 mg THC per piece, available in 5-piece and 10-piece packs.

Rotating small-batch live rosin from other licensed processors. Additional 1 g live rosin jars from rotating NYS-licensed solventless processors. Cultivar-specific terpene profiles.

Live rosin can be consumed several ways:

Dabbing. A small amount (typically a rice-grain-sized dose for a starter) is heated on a dab nail or e-rig and the vapor is inhaled. This is the most flavor-forward consumption method.

Vape cartridge. Live rosin cartridges screw onto a standard 510-thread battery and are consumed through the battery's button or draw activation.

Disposable vape. Single-use pens require no battery or cartridge swap. Inhale to activate.

Flower top-coat. A small amount of live rosin applied to a packed bowl or rolled into a joint adds potency and flavor to flower consumption.

Edible. Live rosin gummies provide an edible format for solventless concentrate.

Live rosin is significantly more potent per volume than flower. A typical live rosin cartridge tests at 60 to 85 percent total cannabinoids. A typical pre-roll flower tests at 18 to 30 percent THC. The per-puff dose from a live rosin product is roughly 2 to 4 times higher than the per-puff dose from flower.

Recommendations for live rosin newcomers:

Start with a single small inhale. Wait 5 minutes to assess effect before taking a second inhale.

Use the lowest-rated of the cartridge or disposable formats to gauge personal response.

Avoid combining first-time live rosin consumption with alcohol or other substances.

Hydrate during and after consumption.

For dab rig consumption, start with a rice-grain-sized amount.

Solventless production is more labor-intensive and lower-yielding than hydrocarbon extraction. Producing 1 g of live rosin requires significantly more starting flower than producing 1 g of live resin or wax. The yield ratio favors solvent-based methods.

The Alchemy live rosin price points typically range:

1 g live rosin jar: $60 to $100, depending on cultivar and processor.

0.5 g live rosin cartridge: $45 to $70.

1 g live rosin cartridge: $80 to $110.

Live rosin gummies (10-piece, 100 mg total): $25 to $40.

The price premium reflects the production cost and the preservation of the full terpene profile.

The current live rosin drops feature cultivars across the indica, sativa, and hybrid spectrum. Specific cultivars rotate weekly based on processor pipeline.

Recent cultivars on the shelf include phenotypes of Wedding Cake, Zkittlez, Apples and Bananas, and seasonal small-batch cultivars from NYS craft cultivators. The cultivar shifts as new lots arrive and existing lots sell through.

The live rosin section of thealchemy.nyc updates in real time as new lots arrive. Loyalty members at Silver tier and above receive 24 to 48 hour advance notice of premium small-batch drops by email.

Customers can also stop into Chelsea or Flatiron and ask the budtender what is fresh on the live rosin shelf this week.

A premium concentrate without a credible COA is not premium. NYS adult-use compliance requires every retail product to ship with a Certificate of Analysis from an ISO-17025 accredited laboratory. For live rosin specifically, the COA pages worth your attention are the cannabinoid profile, the terpene profile, the residual solvent screen, the pesticide screen, the heavy metal screen, and the microbial screen.

On the cannabinoid profile, look for total THC and total CBD plus the minor cannabinoids (CBG, CBN, CBC). A clean live rosin pull typically shows 65 to 80 percent total THC with a meaningful CBG (often 1 to 3 percent) and a small CBN reading. On the terpene profile, look for total terpenes ideally above 4 percent. Anything above 6 percent is exceptional. Common dominant terpenes in current Alchemy drops include beta-myrcene, limonene, linalool, beta-caryophyllene, alpha-pinene, terpinolene, and humulene. The residual solvent screen on a solventless rosin should read non-detect across the board (since solvents are not used in production); any detection above the action limit indicates contamination from upstream handling and should never reach the retail shelf. Pesticide and heavy metal screens follow the NYS Cannabis Control Board action limits published by OCM. The microbial screen tests for aerobic bacteria, yeast, mold, salmonella, E. coli, and Aspergillus.

A budtender at either Alchemy location will pull up the COA on the in-store iPad for any live rosin product before you purchase. If a COA is missing, expired, or fails any screen, the product does not ship.

The most common question at the concentrate counter is whether live rosin is "better" than live resin. The honest answer is that it is different, not strictly better, and the right answer depends on the customer.

Live resin uses hydrocarbon solvents (typically butane or propane) to strip cannabinoids and terpenes from fresh-frozen plant material. The resulting oil is then purged of residual solvents through vacuum-oven processing. A well-produced live resin passes the residual solvent screen at the parts-per-million level and carries an intense terpene profile because the solvent extraction is highly efficient at pulling volatile terpenes. The flavor is bright and the cannabinoid loading is high. The downside is the production process involves hydrocarbon solvents, which some customers prefer to avoid for personal or philosophical reasons.

Live rosin uses ice water, agitation, heat, and pressure. The starting material is fresh-frozen flower washed through progressively finer screens to isolate the trichome heads. The resulting ice-water hash is then pressed between heated plates to release the rosin oil. The result is a cannabinoid and terpene concentrate that has touched only water and pressure. The terpene profile is often described as more nuanced, with sweeter and rounder character than the bright top-note of solvent-extracted live resin. The cannabinoid loading typically runs slightly lower than the cleanest live resin, but the absence of any solvent residue is the selling point.

We carry both at The Alchemy. The Mfused team produces both rosin and resin and we stock the rosin line at premium price tiers and the resin line at a slightly lower tier. Customers who price-sensitive on a concentrate gravitate toward the live resin shelf; customers who prioritize the solventless story gravitate toward the rosin shelf. Neither answer is wrong.

Live rosin stores best in a sealed glass jar at refrigerator temperature (35 to 40 degrees Fahrenheit) for long-term storage of more than 60 days, or at room temperature in a cool dark drawer for short-term storage of less than 60 days. UV light and heat are the two primary degradation vectors. THC oxidizes to CBN under prolonged light or heat exposure, and the volatile terpene profile evaporates over time even in a sealed container.

The trade-off with cold storage is that cold rosin is harder to dose because the consistency stiffens. Most customers pull the jar from the fridge 10 to 15 minutes before use, allow it to come up to manageable temperature, dose what they need, and return the jar to cold storage. A well-stored live rosin jar retains its flavor profile for six to nine months. A poorly-stored jar (sun on a windowsill, room above 75 degrees, repeated open-and-close handling) degrades to noticeably duller flavor in four to eight weeks.

Cartridges and disposables are less storage-sensitive because the oil is sealed against air exposure inside the cartridge. Standard guidance is to store cartridges upright, at room temperature, away from direct heat. A cartridge stored on its side for long periods can develop a small air gap that affects the wick saturation and the draw quality.

A few patterns recur at our concentrate counter that may help readers self-identify.

The first is the flower-graduate. A customer who has been smoking flower for years walks in asking about concentrates because a friend showed them a dab rig and the flavor blew them away. The right product for this customer is a 1 g live rosin jar plus a small electronic dab device from our accessory selection. The flavor depth from a single low-temperature dab is the experience that converts flower-drinkers into rosin-drinkers, and the lower-temperature pull preserves the terpene profile that justifies the premium price.

The second is the convenience-led customer. They want potency without setup. The right product is a 0.5 g or 1 g live rosin cartridge plus a 510-thread battery. The Chelsea counter sees this customer most often around 5 pm on weekdays when commuters from Penn Station are walking three blocks to our location. The convenience pull works for an apartment after work without smell or rig setup.

The third is the edible customer who wants a cleaner experience than standard distillate gummies. The right product is the Mfused live rosin gummy line. The terpene preservation in a solventless edible produces a more characterful experience than the typical distillate-and-flavoring gummy, and customers who have plateaued on standard gummies often report a noticeable depth difference.

The fourth is the connoisseur. They know rosin. They know terpene profiles. They walk in asking what is fresh and the answer is usually the most recent small-batch drop. We try to keep at least one connoisseur-tier rosin on the shelf at any time.

A 1 g Mfused live rosin jar at Chelsea today prices at $80 pre-tax, lands at approximately $98 with NYS adult-use tax (13 percent) plus NYC sales tax. A small-batch 1 g jar at the same shelf prices at $95 pre-tax, lands at approximately $116 at the register. A 0.5 g Mfused live rosin cartridge prices at $55 pre-tax, lands at $67 at the register. A 1 g cartridge prices at $95 pre-tax, lands at $116 at the register. A 10-piece live rosin gummy package at 100 mg total prices at $35 pre-tax, lands at $43 at the register.

A reasonable first-visit rosin purchase is a single 0.5 g cartridge plus a 510-thread battery for total spend in the $80 to $100 range. A reasonable connoisseur purchase is a 1 g small-batch jar plus the customer's existing dab setup for total spend in the $115 to $130 range. A reasonable edibles-curious purchase is a 5-piece or 10-piece live rosin gummy package for total spend in the $20 to $45 range.

The NYS adult-use possession limit on concentrates is 24 grams, separate from the 3-ounce flower limit. A single transaction can fulfill the limit. Most customers buy far less. Concentrates must be transported in their original NYS-compliant child-resistant packaging and may not be consumed in public spaces, in vehicles, or in workplaces. Concentrate consumption by minors is prohibited. All Alchemy live rosin products ship in NYS-compliant packaging with full label information and COA QR codes.
