Color and Cannabis Concentrate Quality

What’s a cannabis concentrate?

Cannabis concentrates are highly condensed components of the cannabis plant.  A quality concentrate contains only desired components like THC, CBD, and terpenes, while lesser quality concentrates also contain undesired components like fats, waxes, foreign contaminants, and excess residual solvents.  The myriad of textures, colors, aromas, and quality identifiers became overwhelming and confusing, so I set out to break down the basics of this mysterious concentrate magic mumbo-jumbo for us amateurs.

I will discuss the basics about concentrates and reference articles that articulate those points far better than I can, so please follow the links and check out the articles for a comprehensive understanding of this post.

What’s the best form/texture for a concentrate?

If you’re not clear on the various forms concentrates take, their textures, and the processes used to make them, ‘What Are Cannabis Concentrates A Guide to Extraction Techniques’, is a helpful guide (except for off-the-mark comments on alcohol extraction).

It’s easy to get overwhelmed by the different concentrates, but they’re all quite similar.  Ryan, from Steep Hill Labs, makes some excellent points in this Leafly article, ‘What Does Good BHO Look Like Dabbing and Hash Oil Myths Part One’.  First, a concentrate’s physical form is no indicator of quality but simply a preference in process or handling.  Ryan says, “The biggest misconception that most people have is there’s some chain of hierarchy in how your oil, concentrate, wax and shatter ends up looking.  The difference could be as simple as a few molecules of H2O, that’s it.” Somewhere along the way, people bought into the “If it ain’t shatter, it don’t matter” mantra, but as we now know, the only part of that saying that’s correct is the latter half, “It don’t matter.”  Sap, pull-n-snap, shatter, wax, budder, crystals, or whatever, let’s go.

What’s the best color?

Concentrates vary in color from blazing yellow to absolute black.  The darkest concentrates are made for ingesting orally, making suppositories, or used topically. Anything green or black is not suitable as quality smoking material.  For smoking, desired colors range from yellow to dark brown and clarity from clear to barely opaque.  I have seen many self-proclaimed extract professionals dismiss concentrates from afar simply by observing the color.  This is not only silly but just not possible.  Ryan also makes a good point in the Leafly article concerning how a concentrate’s clarity can be misleading.  Quite often, a clear color can indicate a lack of proper purging, while proper purging can and does darken a concentrate, making it more opaque than clear.  This is especially the case with alcohol extraction.  He points out, “[Steep Hill Labs] has done over 10,000 tests, and when we test these concentrates, it’s more likely that clear shatter is going to have higher parts-per-million residual solvents.  That doesn’t mean there’s not clear shatter that doesn’t come out with zero PPMs, it just means that more times than not, (clearer) shatter will have higher parts per million.”

Another article by Green Soma, “How to Shop for Marijuana Oil” (scroll down past mid-page), goes on to explain, “There are many dark brown oils, which are properly extracted, aromatic, with wonderful effects. Conversely, there are plenty of lighter gold oils which are actually improperly extracted with bad solvent, and which do not produce the best psychotropic or other affects. Don’t take color as the best indicator.”

So, what does color tell us?  The truth is, very little on its own.  Color is affected by many factors, from growing through harvest all the way to a concentrate’s final purge.  A significant influence is how long after harvest the cannabis was extracted.  Fresh trichomes, like in live resin and fresh frozen, will inevitably extract with a much lighter color.  However, suppose the cannabis used in a live resin was not grown well, and the trichomes didn’t mature well. In that case, it will still be very light in color and pretty in appearance, while a darker concentrate produced from material grown and cured by a master will be darker and vastly superior quality.  Furthermore, if the lighter live resin wasn’t purged well, it would be even lighter; if the darker extract was perfectly purged, it would be even darker.  Just like everything, color is not a reliable indicator of what’s on the inside.

So how do I discern ‘Quality’ for my personal use?

Hands down, the best way to control quality is to grow, harvest, and extract yourself. Then, you can be certain of what‘s in your final concentrate. Unfortunately, most of us don’t have that kind of time or talent, so we have to exercise caution in our purchasing decisions.  When purchasing concentrates, you can’t be positive about the original material’s origin, but you should always ask the question and demand a solid answer.  If the answers aren’t forthcoming or satisfactory, don’t buy.

If you’re comfortable with the origin of the cannabis used in the concentrate’s production, then an initial visual inspection should confirm three things.  First, no foreign object contamination is incorporated from an unclean work area.  Second, the color of the concentrate is reasonably consistent throughout the sample.  Swirling of considerably inconsistent color is sometimes called “poop-soup,” indicating poor butane purging.  Third, there shouldn’t be any green or black coloration for smoking/vaping concentrates.

Lastly, please rely on your nose. It’s the best quality analysis tool we amateurs have access to.  A full, clean aroma will be your best indication of quality processing performed well from beginning to end.  To illustrate how your eyes can be deceived while the nose is most reliable, I love this account of identifying the best concentrate in the above photo in The Weed Blog.  The darkest concentrate was by far the best quality of the four samples.  Further proof that there’s more than meets the eye when discerning concentrate quality for yourself!

FINALLY

The undeniable ultimate measure of quality is proximity.  If you’re the only one with smoke at the party, your shizzle is top quality!

  1. Thanks for the great articles. Do you know if an EU power version of the Source will be available soon? I remember hearing around Christmas?

    1. Hey Tom, thank you and I’m glad the post are bringing something to those that need it. For future product info I can’t tell you. I would suggest contacting the company

  2. An interesting article. What I am looking for is a way to make my products a more consistent lighter color, and maintaining (if not improving) the quality. While color is not a true mark of purity, potency or flavor, lighter extracts do appear to be favored by those consuming.

    I wonder, in CO2 extraction, which pressures/temperatures can be used fracture off the desired levels.

    Thank you for the article.

    1. Lighter colored extracts are favored like Victoria Secret Models are as well. The simple fact is for the most part they aren’t standard issue. People are enamored by the unicorn not understanding all the tricks people posting the yellow photos are using. The obvious good exception is live resin and fresh material with young peppy trichomes that come out screaming yellow gold. A lot of the other stuff is light due to illusion, trickery and often a total lack of purging. Look, smell, try that’s good enough for me…… Thanks for sharing your thoughts

      1. I am interested in MCT oil extracts using the Levo machine and a Magical Butter combo. Can we chat about this sometime?

      2. Quite honestly I’d say don’t waste your money. The MB is a soy milk maker rebranded as cannabis tool, and the mechanics of the LEVO make little sense for quality infusion technique. A slow cooker or double boiler will do you just as good and probably better. I’m obviously an extraction fan as well so maybe not the best person to ask

  4. Well… Newbie, errors physical body pains…. Well trail samples online two different orders ok…. One from Green Labs Cear like water/second order from CBD LABS, very greenish like grass….. I read your article. I like to think I’m not just dose ing glycerin. Any opinion would be hellllpfull. Thanks SLM. TRACY, CA.

  5. This is a great article and it needs to be made into a poster and hung in every dispensary and also beat into the heads of every middleman that wants to call himself a broker…

  6. Just got a vapor cartridge from friend from New York n it’s clear n very think .. just wanted to no if y’all seen it before thanks

    1. To do naturally the stain would have to have that colored attribute and seems to happen with some strains when grown outdoor. In the 70’s they had cherry oil that I believe was a result of a solvent and possibly Isomerization? I would have to dig into it.

      1. please do, that is exactly what im looking for my friend, I had that cherry oil several times in the late 70s, never to be seen again. Ive been researching and researching for over a year now, I have some ideas of landrace used, and a couple different recipes. And I do suspect an acid treatment (isomerization) was also used. But there is no way to confirm it.
        Not like I can ask the chemist that made it.

        it was without a doubt the very best oil ive ever experienced.
        delicious to smoke, clean white smoke, tasted like cherries, smelt like it taste when burnt.
        good euphoric buzz….bright red, not a rust color red, more like Chinese sweet n sour sauce red…this specific oil was a delight, and has never been seen again in over 30 years
        I wish to replicate it.

        It was mass produced and smuggled by a large ring.
        I have confirmed that it was in Tororonto (Can.) and NYC (US) at the same time frame
        This indicates a large ring, Im thinking BOEL
        So im also thinking it was made abroad, either afganistan, Pakistan or lebenon
        (following the hippie trail)….so im currently researching landraces of the era, native to those countries. Also central America too,

        So strains of yesteryear I think could be material used
        cherry bomb(terps), panama red, Lebanese red, PCK (red phenol)
        afgani and/or possible Turkish strains (red phenol)

        I do have some recipes, that call for a hydrochloric acid treatment, that supposedly
        give it a cherry type flavor, but coloring…??

        how do you get a bonified red in your extract, is the $64,000 question….

        any info, would be greatly appreciated.
        I am looking at buying one of those extract turbos, soon

        thank you so much
