Description
A dozen cans at 25mg each, five calories, no sugar. A grapefruit CBD seltzer is one serving per can with the figure stated for the whole container, which is the format’s main virtue and the reason it does not need the arithmetic a concentrated shot needs. Every production run is lab tested and the sheet is posted on this page rather than available on request.
What is in a can of grapefruit cbd seltzer
The per can figure, the pack total and the serving count. Twelve cans at 25mg is 300 mg across the pack.

- Count: 12 cans. Pack total: 300 mg
- Calories: five a can. Sugar: none

- Emulsifier: named on the ingredient list
- Price: $48 a twelve pack, with the price per milligram printed under it
Five calories in a grapefruit cbd seltzer, and where they come from
From the flavour and the sweetener rather than sugar, and the panel names which sweetener it is. A grapefruit CBD seltzer at five calories is close to carbonated water with a flavour in it, which is the whole proposition. Grapefruit is also one of the few flavours that works without sugar, because the bitterness is part of the fruit rather than something being covered up, and a sugar free version tastes more like grapefruit than a sweetened one does.
How a cannabinoid gets into carbonated water
By emulsification. Cannabidiol is an oil and does not dissolve in water, so it is broken into very small droplets with gum acacia, a modified starch or a polysorbate, and the emulsifier is named on the can. Droplet size decides whether the liquid stays clear and whether anything separates on standing. Carbonation adds a second problem, since an emulsion in a pressurised can has a shorter stable life than the same emulsion flat, which is why the best before date on a grapefruit CBD seltzer is nearer than the one on a tincture.
Why a grapefruit cbd seltzer prints the per can figure
Serving size is where the drinks aisle gets slippery. A 2 ounce shot at 100 mg across four servings is 25 mg a quarter bottle and the front label only shouts the 100. The drinks range prints container total, serving total and serving count on every listing, then the per milligram price underneath all three, so a can and a bottle of drops can be compared on the same basis.
Twelve cans, and what the pack costs
Forty eight dollars across 300 mg is sixteen cents a milligram, which makes a twelve pack of seltzer among the most expensive cannabinoid on this site by that measure. You are paying for twelve filled and pressurised aluminium cans rather than one glass bottle, which is a real cost and a real convenience. The figure is printed under the price regardless, including here where it argues for a tincture, and the reasoning is in why price per milligram beats the price on the bottle.
Testing every production run
Every production run of this grapefruit CBD seltzer is assayed by a laboratory outside this business: cannabinoid content per can, pesticides, heavy metals, residual solvents and microbials. Per can assay rather than a batch average is the figure that matters on a filled beverage, because fill accuracy varies down a line. Runs measuring below their printed milligrams are withdrawn and the failing certificate stays published, which is explained in why we publish the batch that failed.
What the published work covers
Pharmacokinetics, and not much on beverages specifically. Published studies report that cannabidiol taken with fat reaches higher blood levels than cannabidiol taken fasted, by several fold in some reports, and that droplet size in an emulsion affects absorption. A can of seltzer contains no fat at all, which is a straightforward statement about the formulation rather than a criticism of it. Head to head human data on specific commercial drinks is scarce. Those sentences describe the state of the evidence, and the regulator’s position on cannabidiol in food and drink is published at fda.gov.
Best before dates are on every can. Chill before opening and store the pack out of the sun. The certificate for the run currently shipping is linked here and filed by lot number.

Solid. Slightly gritty when mixed but dissolves if you wait.
