The Craft of Extraction: Like Beer Making, It’s All About Control

Any brewmaster from the more than 7,000 U.S. craft breweries will tell you one of two things: That their art is a science, or that their science is an art. The answer might depend upon the brewer’s individual approach, but a combination of experience, process, precise measurement and intuition is exactly what’s required to create great beer. In a very similar way, the cannabis industry has its own version of the brewmaster: Extraction technicians.

A cannabis extraction technician deploys knowledge from multiple science disciplines to apply industrial solvents, heat and pressure to plant matter through a variety of methods with the aim to chemically extract pure compounds. Extraction techs use their passion for the cannabis and hemp plants, combined with chemistry, physics, phytobiology and chemical engineering to help create a result that’s not quite art, but not quite completely science. By manipulating plant materials, pressure, heat and other variables, the extraction technician crafts the building block for what will become an edible, tincture or extract.

Similarly, brewmasters use their knowledge of multiple science disciplines like chemistry and microbiology, as well as different brewing processes and a variety of ingredients to develop creative recipes that result in consistent, interesting beers. The brewmaster’s work is both science and art, as well. And they also manipulate plant materials, pressure, heat and other variables to achieve their desired results.

“I would certainly consider brewing to be an art and a science, but it takes a very disciplined approach to create consistent, yet ever evolving beers for today’s craft market,” says Marshall Ligare, PhD. Research Scientist at John I. Haas, a leading supplier of hops, hop products and brewing innovations. “We work to ensure brewers can create something different with every new beer, as well as something that helps create an experience as well as a feeling.”

In both brewing and extraction, the art comes in the subjective experience of the craftsman and his or her ability to curate the infinite possibilities inherent in each process. However, both are a science in their requirement of establishing production methodologies that guarantee a consistent, reliable product experience every time to win customer loyalty (and regulatory compliance). In the same way hops determine recipes for beer flavors, the cannabis plant determines extraction recipes, especially considering the role that terpenoids play in the quality, flavor and effects of the end product.

The development of new and appealing cannabis products is beginning to mimic the vast variety of craft beers now found all over the world. In the same way beer connoisseurs seek out the perfect stout, lager or IPA, discriminating cannabis consumers now search for that gem of a single-origin, specialty-strain vaporizer oil or irresistible dab extract.

“I see an exciting new day for quality-focused, craft extraction that tells a story, not only of where the cannabis plant might have been grown and how, but also the care that was taken in the processing of that strain into smokable or edible oil,” says John Lynch, Founder of TradeCraft. “Imagine the impact in the marketplace when product-makers figure out how to do seasonal one-offs where engaged connoisseurs are willing to pay a premium for the art behind limited releases.”

In either process, you’re essentially creating art with science. Each process works with different strains. Each is concerned with chemical and flavor profiles. Each has its own challenges. In both worlds, quality depends upon consistency. You’re creating art, but you need to replicate that art over and over – which can only occur with strict control of the process. Brewmasters seek control of things like yeast quantity and health, oxygen input, wort nutritional status and temperature, among other things. In their pursuit, extraction technicians seek to control temperature, pressure and flow rate–as well as all the ways these variables interact with each other. What enables this control in both efforts is the equipment used to achieve results.

“A modern brewhouse is very much like a scientific laboratory,” Ligare says. “Brewers treat their setup with the same care and attention a scientist gives to their lab equipment, and are equally concerned with precision, cleanliness and the purity of the result. With each new beer, they want to develop a process that can be controlled and replicated.”

The key to creating a precise process is to use instrument-grade extraction machinery that performs to specifications – and allows you to repeat the process again and again. The value of using high-quality instrumentation to manage and monitor either the brewing or extraction process cannot be overstated. Although it seems counterintuitive, this is where the “craft” comes into play for both brewing and cannabis extraction. Precise instrumentation is what allows the brewer or extraction “artist” to manipulate and monitor the conditions required to meet recipe standards. Along with the quality of the ingredients (hops, cannabis, hemp, etc.), the quality of the equipment utilized to create the product is one critical element impacting the end result. “Imagine the impact in the marketplace when product-makers figure out how to do seasonal one-offs where engaged connoisseurs are willing to pay a premium for the art behind limited releases.”

In cannabis extraction, a second crucial decision is determining which solvent is the best solution for the recipe you’re using and the end result you’re hoping to achieve. This decision is a part of the “craft” of extraction, and determined according to a combination of criteria. There’s no question that each solvent has a business case it serves best, and there is ongoing debate about which approach is best. But overwhelmingly, the solvent that best serves the most business needs is CO2 due to its inherent versatility and ability to have its density tuned to target specific compounds.

“Control is what makes or breaks any craft product,” says Karen Devereux, Vice President of Northeast Kingdom Hemp. “We’re based in Vermont and love how Vermont is known for its quality craft beer, cheese and maple syrup. We wanted to bring that craft approach to hemp extraction, and everyone knows that any craft endeavor is focused on the details and getting them right again and again. You can’t do that without controlling every aspect of the process.”

Greater control of the process can also open up worlds of discovery. The inherent “tunability” of CO₂ enables the extraction technician to target specific compounds, enhancing the potential for experimentation and even whimsy. This can lead to entirely new products much in the way a brewer can control his process to create new, interesting beers.

American portrait photographer Richard Avedon famously declared that art is “about control,” describing the artistic process as “the encounter between control and the uncontrollable.” The same can be said for beer making and cannabis extraction. The more precisely you can control variables, the more options you’ll have for yourself and your customers. The more choices you’ll have with regard to different recipes and products. And the more loyalty you’ll ultimately generate among fans of your products.

Consumer Education: Transparency is King

Making Cannabis Transparent: The Future of the Industry is Information and Data

The last decade has been marked by great strides in the cannabis industry, as public awareness surrounding the health benefits of marijuana-infused products has spread and products have become increasingly well researched and scientifically advanced. Despite this significant progress, however, cannabis legislation and regulations continue to vary widely between states, ultimately contributing to a lack of clarity within the industry.

This issue was at the forefront of the DispensaryNext Conference and Expo agenda held in Denver a few weeks ago. During the expo’s Consumer Safety and Education discussion, a panel of industry leaders including Kevin Gallagher, director of compliance and government affairs at Craft Concentrates and executive director of the Cannabis Business Alliance (CBA); Eileen Konieczny, registered nurse and president of the American Cannabis Nurses Association; Kevin Staunton, director of business development at RM3 labs; and moderator David Kotler, a partner at Cohen Kotler P.A., highlighted a number of important issues for cannabis patients and adult-use consumers, as well as what’s next for physicians, testing labs and dispensaries across the industry. A number of common themes resonated in their discussion of opportunities and challenges, ultimately pointing to a need for increased research and data, and most notably, a growing demand for transparency industry-wide.

Medical practitioners and dispensary technicians need qualified and legitimate information.

Konieczny opened by stressing that the industry must stop calling dispensary sales associates “budtenders.” “I prefer the term ‘dispensary technician.’ These are knowledgeable people who are on the front lines, helping patients understand the products available to them. They deserve a title to reflect that our industry and their knowledge is much more than ‘bud,’” says Konieczny.

These are knowledgeable people who are on the front lines, helping patients understand the products available to them. The most prominent information gaps in the industry lie at the level of dispensary technicians and medical practitioners. The ideal scenario for patients who are looking to use cannabis as medicine is that their medical practitioner is educated about the endocannabinoid system and that the products are available locally so that a treatment plan can be developed based on their needs. But the reality is that many patients enter their local dispensary without much knowledge or support at all, relying on the professionalism of the dispensary staff to help them navigate the dizzying array of products.

Putting the patient’s safety and success first, it is imperative that everyone involved has the proper data and information to make the best choices. However, dispensary technicians should be extremely careful to avoid making health or benefit claims. As Gallagher noted, “It is not only illegal, but also unethical to make medical claims as a dispenser. There is a difference between a claim and a personal experience. A dispenser can tell their customer that a certain strain helped them personally, but they cannot tell the customer that the strain will cure their specific ailment.”

The industry needs transparency.

New cannabis consumers may have a certain degree of misunderstanding of the products they are consuming and unfortunately, manufacturers do not offer a high level of transparency in disclosing ingredients, thereby preventing these customers from becoming better informed.

While educating the public is essential, educating the industry is of equal importance.Furthermore, labels often contain small barely legible type, along with confusing and unnecessary content. According to Gallagher, the labels need to be simpler. “Products are overloaded with redundant, confusing language that most consumers don’t understand. This turns them off—especially if they’re inexperienced in this realm,” says Gallagher. When customers who are new to cannabis find products off-putting, it hurts not only the industry, but also their own health. Ill-informed consumers may have trouble understanding how cannabis can help them, and therefore they can miss the benefits it provides.

While these issues are prevalent, there are many ways they can be resolved—with transparency at the core.

Research is critical and paramount.

For cultivators or manufacturers, research and data hold the key to attracting new consumers. By providing details about what is in a product and implementing certifications to show the product is contaminant-free, manufacturers are able to provide transparency and offer differentiation.

During the panel, Konieczny pointed out another common mistake that many manufacturers make—not sharing test results. “Not many are posting their test results, and yet this is one of the leading avenues that can increase revenue,” says Konieczny. “Most people just want to feel well again, so providing test results adds a layer of legitimacy for patients who are wary to try a new product.”

With all of this in mind, it is perhaps most important to consider the way that this information is conveyed. Facts and research are useless if they are not accessible to consumers, who may not comprehend complex data. “We need to present information in plain language, keeping it clear and simple to understand,” expressed Konieczny. The simpler the delivery, the better it will be understood and knowledge is a very powerful tool for patients, consumers and the bottom line.

Educating the educators.

While educating the public is essential, educating the industry is of equal importance. For instance, thoroughly training dispensary technicians to ask the correct questions and identify first-time users will ensure consumer safety while avoiding improper use.

The industry as a whole depends on transparencyEducating professionals on better product labeling is another critical way that the industry is working to improve itself. There has recently been a push at the manufacturing level for standardization in product labeling, as establishing a clear standard can aid customers in successfully using cannabis. “In working groups with Colorado’s MED (Marijuana Enforcement Division), we aim to standardize specific product categories, remove irrelevant names, and harmonize medical and retail labeling regulations,” says Gallagher. “Ultimately, we want to consolidate language and make it more transparent in promoting public health and safety so that it can be easily read and understood.”

All panelists agreed transparency is paramount for the future of the cannabis industry and for growing a brand. Using lab data can provide value, setting a brand apart and building loyalty among consumers looking for someone they can trust.

“Transparency is king,” Gallagher urges. “The more we educate consumers and professionals, the more clarity we will see at all levels, ultimately minimizing risk and creating greater demand among those consumers. The industry as a whole depends on transparency.”
