Inside the Lab: How Every Batch Gets Tested

Potency, pesticides, heavy metals, microbials. The pass-or-no-ship process.

Inside the Lab: How Every Batch Gets Tested

"Lab-tested" is on every cannabis package in California. It also means almost nothing if the brand pays the lab. Sauce uses independent state-licensed labs, and we don't ship product until the COA passes — every batch, every time.

Here's exactly what gets tested, what we look for, and what fails the batch.

The five tests every batch passes

California regulation requires testing on five categories. We hold to those plus our internal stricter thresholds.

1. Potency — THC, CBD, minor cannabinoids

Every batch gets HPLC-tested (high-performance liquid chromatography) to measure exact concentrations of THC, CBD, CBG, CBN, and THCa. The number on your packaging is the number from this test. We don't round up. We don't average across batches. State regulation allows ±10% variance from what's printed; we hold ourselves to ±5%.

2. Pesticides

California regulates 66 pesticide compounds across two tiers. Tier 1 (myclobutanil, chlorpyrifos, others) must be undetectable. Tier 2 (most others) must be below thresholds measured in parts per billion. The lab uses LC-MS/MS and GC-MS/MS to detect at extremely low concentrations.

Our internal rule: any detection in Tier 1 fails the batch. Period. No remediation, no re-extraction. The batch gets destroyed.

3. Heavy metals

Cannabis is a hyperaccumulator — it pulls heavy metals out of soil and concentrates them in the flower. We test for lead, arsenic, cadmium, and mercury via ICP-MS (inductively coupled plasma mass spectrometry). Sauce uses only licensed cultivators with verified soil and water sources, but every batch still gets heavy-metal screened. Trust, then verify.

4. Microbials

Mold, yeast, salmonella, E. coli, aspergillus. The lab cultures samples on agar and uses qPCR for fast pathogen detection. A failed microbial test is the most common reason a cannabis batch gets destroyed industry-wide. It's also the reason "factory direct" counterfeits are dangerous — they skip this entirely.

5. Residual solvents

For our concentrate-based products (Sauce Essentials live resin, Sauce ONE pods), we test for residual solvents from the extraction process: butane, propane, ethanol, acetone, hexane, and 23 others. Threshold is 1 ppm for most. Our products consistently come back at <0.1 ppm — effectively undetectable.

What a real COA looks like

A Certificate of Analysis (COA) is the document the lab issues for each batch. It contains:

Our COA library lets you look up any batch number and see the full lab report. Transparency is our anti-counterfeit policy — and it's a good filter for any cannabis brand. If they can't show you the COA, walk.

Why we publish them

Most cannabis brands keep COAs private or hand them over only when asked. We publish every one. Two reasons:

  1. If we're going to ask you to trust the verifier code on your package, you should be able to verify the lab work behind it.
  2. Public COAs make counterfeiting harder. If a fake claims to be a Sauce batch, you can pull our COA for that batch number and see the difference immediately.
Verify your batch. Got a Sauce product in front of you? Pull the batch number off the package and search the COA library. Or use the verifier for the fastest authenticity check.

The bigger picture

"Lab tested" is the floor in regulated cannabis, not the ceiling. The point isn't whether a brand tests — it's whether they test rigorously, publish honestly, and destroy batches when they fail. We do all three. That's the Sauce standard.
