A wellness shot for cannabis consumers who needed something more than water and patience.
How PMG developed a cannabis recovery beverage from scratch, evolved it into a more functional shot format, and replaced the standard preservative stack with a clean-label natural preservation system that survived 18-month shelf life testing.
A category gap created by a fast-changing market.
As legal cannabis markets expanded across the United States — recreational, medical, and the rapidly evolving hemp-derived cannabinoid landscape — consumer behavior shifted faster than the product categories serving those consumers. More people were trying cannabis products for the first time. More existing consumers were trying higher-potency formats. The same predictable thing happened that has happened with every consumer category: a meaningful percentage of people were having stronger experiences than they intended.
The cultural response was practical advice. Drink water. Eat something. Wait it out. Some of it worked. None of it was a product.
Our client — an emerging wellness brand with a sharp read on the cannabis consumer demographic — came to PMG with a specific observation: there was a clear consumer need for a functional product that could help someone feel more grounded when their cannabis experience had become more intense than they wanted, and no one in the market was making one that was clean-label, evidence-grounded, and consumer-friendly.
The brief: develop a functional beverage that delivered ingredients with established mechanisms for promoting clarity and balance, tasted good enough for daily use, and could sit on a shelf for 18 months without preservatives the brand's clean-label consumers would reject.
The formulation problem under the marketing problem.
The functional ingredient selection was the manageable part — black pepper extract, certain terpenes, L-theanine, specific B vitamins, ginger. Building a complementary stack of these ingredients into a single beverage formulation was challenging but achievable.
The harder problem was preservation. Functional beverages typically rely on potassium sorbate, sodium benzoate, citric acid as a pH adjuster, and sometimes EDTA. This system works — but the consumer demographic for this product reads those preservatives as a deal-breaker. The client wanted to launch into clean-beauty-adjacent retail channels and DTC. The preservatives would have failed retailer compliance lists and triggered consumer rejection. But removing them without an alternative would have collapsed shelf life to 30 days under refrigeration — operationally impossible for a retail product.
We needed a preservation system that achieved 18-month ambient shelf life using only consumer-recognizable, label-friendly ingredients, without affecting flavor, meeting FDA (Food and Drug Administration) requirements, and passing microbial challenge testing.
A natural preservation system built around hurdle technology.
Our R&D team worked through a multi-stage development process over approximately five months. The approach we landed on used "hurdle technology" — a food science principle that achieves preservation through the combination of multiple smaller barriers rather than a single dominant preservative.
The specific system combined: naturally derived organic acids at carefully calibrated concentrations to achieve target pH without the harsh mouthfeel of standard citric acid systems; specific botanical extracts with documented antimicrobial properties that doubled as supporting functional ingredients; controlled water activity through the beverage's natural sweetener and ingredient density; and oxygen-scavenging packaging that extended shelf life without requiring additional in-product preservatives.
None of these elements alone would have achieved the required shelf life. Together, they created a preservation system that met every requirement — performance, label-friendliness, flavor integrity, and regulatory compliance.
An 18-month ambient shelf life. A clean label. And a reformulation into a more concentrated shot format.
The original formula was developed as a 4-oz beverage. During stability testing and consumer feedback, the client identified an opportunity: a 2-oz shot format delivered the same ingredient dose with better portability, better retail shelf economics, and a consumption format more aligned with how the target consumer would actually use the product.
PMG reformulated from the beverage format to the shot format while preserving the natural preservation system. The shot format passed 18-month accelerated and real-time stability testing, passed microbial challenge testing to USP 51, and launched in both DTC and specialty retail channels.
What this case study demonstrates about PMG's capabilities.
- Natural preservation system formulation — a technically demanding capability not every contract manufacturer brings
- Beverage R&D across format evolution — from concept to 4-oz beverage to 2-oz shot, same manufacturing relationship throughout
- Clean-label requirement navigation — meeting aggressive label standards without sacrificing product stability
- Regulatory compliance in a complex category — cannabis-adjacent wellness operates in a category where a single wrong claim creates real exposure
