Quality & Lab Testing
Every batch. Every test. Every COA.
We third-party lab test every batch we ship and publish the results here. If a number isn't on the COA, we don't print it on the box.
A lot of rosin sold online has never been tested by anyone. No COA, no batch ID, no real lab. Just a clean website and a story about craft.
That isn't how we do this.
Every Mindful Reserve batch goes to a licensed California cannabis testing lab before it leaves our facility. The lab tests against the full state-mandated panel, prints a Certificate of Analysis, and that COA is what we publish below. The label on your unit matches the lab report — down to the batch ID, the test date, and the lab’s license number.
The Panel
What every batch is tested for
Nine independent screens, one report. Each panel below is run on every released batch.
Cannabinoid Potency
Total THC, CBD, CBG, CBN, and minor cannabinoids by HPLC. The label number on the box matches the COA — never the other way around.
Terpene Profile
Full terpene panel by GC-MS so you can see why one batch tastes like pine and another like citrus. Strain-specific batches are documented, never blended.
Pesticides
Screening against the full California Bureau of Cannabis Control Category I and II pesticide list. Action limits, not just detection.
Residual Solvents
Tested even though our process uses none. Solventless means solventless — the COA proves it instead of asking you to take our word for it.
Heavy Metals
Lead, arsenic, cadmium, mercury. Cannabis is a hyper-accumulator — what was in the soil ends up in the plant. We test, then we know.
Microbials
Total yeast & mold, total coliforms, E. coli, and Salmonella per CA limits. Required for any compliant flower or extract; we publish results either way.
Mycotoxins
Aflatoxins B1, B2, G1, G2 and Ochratoxin A. The contamination most commonly missed by gray-market processors.
Water Activity & Moisture
Indicators of microbial-growth risk over a product’s shelf life. Quietly important for a fresh-frozen rosin program.
Foreign Material
Visual & microscopic inspection for hair, insect parts, mold, or anything else that doesn’t belong in your cart.
The Process
How our live rosin is made
Our 0.5g disposable is filled with 100% solventless live rosin — ice-water hash pressed into rosin using only heat and pressure. There are no chemical solvents at any stage. There never were.
- 1
Fresh-frozen flower
Harvested at peak terpene expression and frozen immediately. The plant never sees a drying room. This is the difference between live rosin and cured rosin — and it’s why our terpene profile reads the way it does.
- 2
Ice-water hash
Trichomes are separated from the plant material with cold water, ice, and gentle agitation. No solvents, no chemicals, no shortcuts. The result is hash — a concentrated mass of intact resin glands.
- 3
Rosin press
The hash is pressed between heated plates under controlled pressure. Heat and pressure only. What flows out is rosin: full-spectrum, terpene-rich, single-cultivar, ready to fill.
- 4
Ceramic-coil disposable, USB-C rechargeable
Rosin is loaded into a ceramic-coil all-in-one, USB-C rechargeable so you finish the unit instead of throwing it away half-charged. Child-resistant, CA-compliant, recyclable hardware. No cutting agents, no botanical terpenes added back, no MCT, no PG, no VG.
What you won't find here
The cannabis cart category is full of additives, blends, and shortcuts that quietly take over once a brand starts optimizing for margin. None of these are in our product. Ever.
- ×Cutting agents (no MCT, no PG, no VG, no Vitamin E acetate — ever)
- ×Botanical or synthetic terpenes added back after extraction
- ×Distillate blends or rosin‑and‑distillate hybrids sold as “rosin”
- ×Artificial flavoring
- ×Solvent extraction (no butane, no propane, no CO₂, no ethanol)
- ×Strain blending across the disposable line — every batch is a single cultivar
A Quick Primer
How to read a COA
Whether you're looking at one of ours or anyone else's, here's what should be on it.
1. A real, named lab with a license number
If the COA doesn't name a licensed testing facility, it isn't a COA. California labs are licensed by the Department of Cannabis Control — the license number should be printed on the report.
2. The batch ID matches the unit
The batch ID on the COA should match the batch ID printed on the box and the unit itself. If they don't match, the COA is for a different batch — and you have no idea what's actually in your hand.
3. A date — and it should be recent
The test date matters. Old reports get reused on relabeled batches. If the COA is more than ~12 months old for a flower-derived product, ask why.
4. All required panels, not just potency
Many gray-market reports show only the cannabinoid potency line. A real CA-compliant COA covers pesticides, residual solvents, heavy metals, microbials, mycotoxins, water activity, and foreign material. If those panels aren't there, the product hasn't cleared CA compliance.
5. “Pass” / “Fail” printed in plain English
A compliant COA tells you whether the batch passed or failed each panel. If you can’t find that on the report, you’re looking at a screening document — not a release decision.
Our COAs
Released batches
Every batch we ship is listed here with its lab, test date, and a link to the full Certificate of Analysis. Nothing redacted, nothing summarized.
First-batch COAs coming soon
Our first commercial batch is in final testing. The COA will be posted here the moment it clears, and every batch from then on will follow it.
If you're a buyer or researcher who needs the current COA before launch, request it directly at info@mindfulreserve.com.
Where to find Mindful Reserve
Right now, just one shop — The Pocket Dispensary in Sacramento. We’d rather be on a small number of right shelves than a big number of wrong ones.
