Our complete CBG lineup: 4 products and the research behind them
The short version:
- We just launched four CBG products: two coffees (150mg and 300mg CBG+CBD) and two water-soluble tinctures (300mg and 900mg).
- The tinctures use a water-soluble formula that mixes into drinks and has almost no taste.
- If your first bag or bottle isn't right for you, email us within 30 days of delivery for a full refund. No need to send it back.
CBG has gone from a cannabinoid almost nobody could buy to the most interesting thing happening in functional coffee. We've spent the last stretch reformulating and testing so we could launch a CBG line we'd actually stand behind. Here's everything we shipped, the research behind it, and how to pick the right one.
What we launched
Four products, two formats. The coffees are for people who want CBG built into a morning ritual they already have. The tinctures are for people who want to add CBG to anything, or who want CBG without the coffee.
Colombia CBG Coffee, 150mg CBG + 150mg CBD
Our entry-strength CBG coffee. Single-origin Colombian beans infused with 150mg of cannabigerol and 150mg of cannabidiol per 12oz bag, 6.25mg of each per 8oz cup. If you already drink CBD coffee and you're CBG-curious, this is where to start. The CBG is flavor-neutral at this dose, so it tastes like the clean Colombian you already know.
Black Label, 300mg CBG + 300mg CBD
The double-strength version. Same Colombian base, twice the cannabinoids: 300mg CBG and 300mg CBD per bag, 12.5mg of each per 8oz cup. Black Label is for daily drinkers who treat CBG coffee as a functional part of the routine and want a dose that lands. Two cups gets you to 25mg of CBG, a little above the 20mg used in the only published human trial on CBG (more on that below).
CBG Water-Soluble Tincture, 300mg
A near-flavorless CBG liquid you drop into anything: water, coffee, juice, a smoothie. The 300mg bottle is the right starting size for most people and the easiest way to add CBG to a coffee you already love without switching beans.
CBG Water-Soluble Tincture, 900mg
The high-strength tincture. Same water-soluble formula, three times the CBG, better value per milligram. The 900mg bottle is for experienced users who already know their dose.
What CBG actually is
CBG is short for cannabigerol. It's called the "mother cannabinoid" because it's the precursor the plant uses to build most other cannabinoids, including CBD and THC, as it grows. By the time hemp is mature, most of its CBG has already converted into other compounds. Typical hemp ends up with about 1% CBG. That's why CBG used to be almost impossible to buy at a real dose, and why CBG coffee is still rare. Producing it takes hemp specifically bred to hold its CBG, harvested before the conversion finishes.
CBG is non-intoxicating. It won't make you high. Our extract is broad-spectrum and contains no detectable THC per our published lab results.
What the research says, and what it doesn't
We're going to be straight with you, because this is exactly where most CBG marketing falls apart. CBG research is real but young. Here's the honest state of it.
The one human trial. The strongest evidence we have is a 2024 single-dose human trial published in Scientific Reports. Participants took a single 20mg dose of hemp-derived CBG. Compared with placebo, the researchers recorded lower self-reported anxiety and stress scores within hours and better scores on a verbal memory task, with no intoxication and no cognitive slowing. Those are that study's findings on isolated CBG, not claims about our coffee or our tinctures. It's the first peer-reviewed human study on CBG specifically, and it's part of why we waited to launch this line.
The preclinical pile. A 2025 review in Frontiers in Pharmacology collects the laboratory work on CBG, including the markers the authors describe around inflammation and oxidative stress, platelet aggregation, and insulin sensitivity. Every one of those results is preclinical, meaning cells and animals rather than people, and none of it describes what a cup of coffee does.
The sleep protocol. A decentralized trial run through the VA system dosed veterans 25mg CBG daily, then 50mg, tracking sleep and biometrics. The protocol is public.
What's still coming. Active human trials at Washington State University (acute physiological effects) and the University of Arkansas (ADHD indicators) are due to report within the year.
The honest summary: one solid human study, a stack of promising preclinical work, and more trials in flight. Anyone selling you certainty about CBG right now is overselling. We'd rather earn the order by being the brand that tells you where the line is.
Why two of these are water-soluble
This is the part we're most proud of.
Cannabinoids are fat-soluble by nature. Your body is about 70% water. Those two facts don't get along. It's why a standard CBG or CBD oil tincture, taken under the tongue, only delivers somewhere between 6% and 19% of its dose into your bloodstream in published pharmacokinetic studies. The rest gets broken down before it does anything. You're paying for milligrams you never absorb.
Water-soluble formulation fixes the mismatch. A 2024 review in Pharmaceutics lays out the nano-emulsion approach: shrink the cannabinoid into particles small enough to disperse in water, and absorption jumps. The numbers from human and clinical work:
- In the Hobbs et al. human study, a water-soluble formulation reached peak blood levels of 2.82 ng/mL versus 0.65 ng/mL for an oil version at the same 30mg dose. Same milligrams, more than four times the peak exposure.
- A clinical study of a water-soluble formulation called Purzorb measured 86% average bioavailability across more than 150 patients, with over half the dose in the bloodstream within 15 minutes.
The honest caveat, again: most of these rigorous absorption studies were done on CBD, not CBG. The molecules are close enough that the formulation principle carries over, but a published head-to-head on CBG-specific bioavailability doesn't exist yet. We expect it within a couple of years and we'll update our pages when it lands.
The practical result: our water-soluble tinctures blend evenly into coffee, water or smoothies, where an oil tincture would separate.
The taste problem nobody talks about
Oil tinctures taste like hemp. Grassy, earthy, a little bitter. That's because the cannabinoid rides in carrier oil that brings the plant's flavor compounds along for the trip. Our water-soluble formula isolates the cannabinoid and emulsifies it into a near-neutral base. A few drops in water, coffee, or juice, and you taste the drink, not the hemp.
For the tinctures, near-zero taste is the whole point. For the coffees, it's different, you want some character there, because the coffee is the experience. Two formats, two jobs.

Frequently asked questions
Does Buddha Beans CBG contain THC?
No. Our CBG coffee and CBG tincture use broad-spectrum hemp extract with the THC removed. They contain no THC detected in third-party lab tests. Batch results are on our certificate of analysis page. State rules on CBD in food vary.
Will CBG make me high?
No. CBG is non-intoxicating, and all four products have no detectable THC.
What's the difference between CBG and CBD?
They're different cannabinoids with different profiles. CBG is the precursor that CBD and others are made from in the plant. They're not interchangeable, and CBG isn't simply "stronger CBD." Our coffees include both so you get the pair together.
Why is water-soluble better than an oil tincture?
Absorption and taste. Oil tinctures absorb poorly in a water-based body (6% to 19% in studies) and carry a hemp flavor. Water-soluble formulas mix into drinks and are nearly flavorless.
How much CBG should I take?
Start low and adjust. The one human trial on CBG used 20mg. Our 150mg coffee is about 6.25mg per 8oz cup, Black Label about 12.5mg. With tinctures, start with a small dose and wait 15 to 30 minutes.
Will any of this show up on a drug test?
Our broad-spectrum extract is formulated with no detectable THC, but no hemp product can guarantee a drug-test result. If you're tested, talk to your provider before using any hemp product.
Can I put the tincture in hot coffee?
Yes. It dissolves in hot or cold liquids without separating, and cannabinoids are stable at drinking temperatures.
