Why “Curing” Kills Terpenes: The Myth of Cannabis Aging
For decades, growers were told that letting cannabis “cure” would make it smoother, richer, and more flavorful—just like a fine wine.
The truth? Cannabis doesn’t vintage. It decays.

I learned this the hard way. Years ago, I set aside harvest after harvest, confident that time would polish the aroma and intensify the flavor. When I finally opened those jars, everything smelled flat—some even turned to hay. The top notes were gone, and what was left was a faint, heavy myrcene funk.
That’s when I realized the entire idea of “curing for better flavor” is a myth built on misunderstanding chemistry.
here are the so-called vaunted Grove bags...

What We Thought Curing Did
Old-school guides described curing as a slow process where moisture “equalizes” and terpenes “develop.”
Growers would jar up flower at 62–65% RH and crack the lids daily for weeks, believing this mellowed chlorophyll and improved taste.
In reality, all that oxygen exchange just accelerates oxidation, evaporation, and chemical degradation.
Wine ages through reduction and controlled polymerization—reactions that only occur in liquid under near-anaerobic conditions. Cannabis, being dry plant matter, has no buffer system. Once air enters the container, the plant’s own enzymes and trace oxygen start dismantling what makes it special.
What Actually Happens Inside the Jar 🤔
Monoterpenes Escape First.
Light molecules like limonene and pinene evaporate within days once internal humidity drops below 60%
Oxidation Follows. Oxygen converts remaining terpenes into aldehydes and terpenoids—the “grassy” or “hay” smell every grower knows.
Chlorophyll and Sugars Break Down.
These release volatile compounds that overpower aroma and create harsh taste.
Permeable Materials Make It Worse.
Even “airtight” jars, Grove bags, and FoodSaver films slowly breathe oxygen.
The result? Crunchy buds, faded color, and lifeless aroma—no matter how good the seal looks.
My Experiments That Proved it :
Rotisserie Chicken Test – Cooked chicken sealed in a DMS™ jar stayed fresh for days while control samples in plastic tupperware turned slimy. Proof that a true vacuum environment preserves texture and moisture even in perishable food. Cats wont eat meat that had started to spoil. This was half a breast chopped. Its more evidence the seal on jar matters.
Grove Bag Storage – 808 Corn B hidden in a drawer came out 2 yeaes later as pure myrcene mint funk with a strange aftertaste.
Partial oxygen exposure caused slow fermentation and terpene imbalance.
FoodSaver “Vacuum” Bags – Crunchy buds inside inflated pouches; trapped CO₂ and leaked oxygen destroyed structure and scent.
Each test led to the same conclusion: permeability is the root cause of terpene loss.
Why Cannabis Doesn’t “Vintage” Like Wine
If curing really improved cannabis, older jars would smell deeper and more complex.
Instead, they flatten out.
Wine ages because trace oxygen interacts with acids and tannins in a buffered liquid.
Cannabis dries out and oxidizes because there’s no liquid phase or chemical buffer.
In short: wine evolves, cannabis erodes.
The Real Path: Depletion and Preservation
True quality comes from proper finishing, not aging.
That means:
- Deplete nutrients before harvest so no residual chlorophyll or salts linger.
- Dry only to the short monoterpene window—when outer fibers flex but don’t snap.
- Seal immediately in a zero-permeability environment (DMS™ jar or 10 mil food-grade Mylar).
Once sealed, chemistry freezes in place. Terpenes stay balanced, moisture stable, and color true.
That’s not curing—it’s preservation
here is your final piece of the evidence
The Truth About “Curing”
I just tried this sealed low-permeability bag, and the results are undeniable. The difference is night and day.
In standard storage—rubber-gasket jars, Mason lids, or latch-tops—oxygen seeps through micro-pores in the gasket and threads. Over time, that slow air exchange strips the top layer of volatile terpenes, flattening aroma and dulling potency.
It doesn’t matter if you use humidity packs or oxygen absorbers—the problem starts at the seal. Impermeability is everything.
This bag shows what no oxygen exchange actually looks like: no cure and no loss. The volatile compounds remain intact, bursting with raw pinene and bright character.
Here’s the truth:
Terpenes in their most active, natural state aren’t meant to be “smooth.” What people call smoothness is really oxidation—the dissipation of flavor over time. “Curing” doesn’t enhance cannabis; it breaks it down.
I’ve lost more harvests than I can count to that myth—stored in jars and grove bags, believing they were improving. They weren’t.
What survived are the field tests that proved what works: sealed negative-pressure storage that halts oxygen infiltration entirely.
That’s why DMS™ storage exists—to stop the chemical decay others mistake for progress.
The question is simple:
Do you keep following the old dogma—or break from it and preserve the truth?
Closing :
I lost too many harvests chasing the curing myth.
Now I know: the best cannabis isn’t aged—it’s protected.
When the last trace of oxygen is gone, time finally stops working against you.
That’s the difference between “stored flower” and preserved flower—and why DMS™ exists.
