Big Sky Botanicals does not give any label info on milligrams of CBD per milliliter serving. However, if you divide their 750 mg (unspecified) bottle by 30, each 1 mL serving should contain 25 mg. Lab A found 26 mg of CBD, which is perfect for their 25 mg dose.

About the product

Big Sky Botanicals claims this is a full spectrum extract that is “rich in minor cannabinoids CBDA, CBN, CBG, CBC, Delta-8 THC, CBDV, THCV, and more.” Our lab tests confirmed a full-spectrum hemp extract containing CBD, THC, CBN, CBC, CBG, and CBDV. However, neither lab found CBDA, THCV, or Delta-8 THC.

The independent labs found that Big Sky Botanicals contained 15% - 30% more cannabinoids than suggested by their label. However, we tested this as total cannabinoids because the label was not specific. Lab A found 782 mg of CBD for this 750 mg (unspecified) bottle, which would be precise if we tested their unspecified milligrams as CBD.

Jeremy's Take

Big Sky Botanicals is a small farm in Whitefish, Montana. They're focused on organic hemp. However, they are not USDA organic certified and I can't confirm those claims. Although there's not much info on Big Sky Botanicals, they passed my company background check.


7.7 cents per milligram of CBD is decent for a cannabinoid-rich full spectrum. It's an even better deal if their claims of organic hemp rich in terpenes are valid. However, I didn't test for terpenes and I can't confirm that they're organic without a USDA organic cert.


Big Sky Botanicals claims this tincture features “a pleasant mint flavor.” I think it tastes earthy, pungent, bitter, thick, and has an odd flavor that I can’t explain. The hemp is emulsified in grape seed oil and hemp seed oil, which I’m ok with. The taste may have something to do with their organic hemp that is rich in beneficial terpenes, which can have harsh flavors. I wouldn't even be able to give this a taste score because I can't handle it, but taste is highly subjective.


A dose of over 25 mg of CBD per milliliter is potent. It also comes with decent amounts of CBC CBG and CBN. However, they specifically claim it’s rich in CBDa, THCV, and Delta-8 THC, which our labs did not find. Delta-8 can have similar effects as THC. This is an excellent full spectrum and there's no need to claim that it has cannabinoids that it doesn't. The label is also lacking information. It states 750 mg but doesn't specify total cannabinoids or CBD. The serving info has zero information about milligrams per dose, which is alarming.

*It's common to see CBD doses at 5 mg, 15 mg, 25 mg, and 50 mg for consumer products. Researchers use much larger doses (25 mg to 1500 mg of CBD). CBD dosing is highly individualized.


The blue bottle and dropper are lovely. However, the label does not specify CBD milligrams and doesn't even suggest a milligram per milliliter dose. A CBD company should not make it this hard to know how much CBD you’re getting per dropper.

Overall Thoughts

The price is ok, the tastes is terrible (in my subjective opinion), the label lacks serious information, and there are cannabinoids specifically claimed by Big Sky Botanicals that both our labs didn't find. However, it's still a good full spectrum with many cannabinoids.
