Fire OG, also sold as Fire OG Kush, is an indica-leaning hybrid made by crossing OG Kush with SFV OG Kush. It is known for a sharp lemon aroma over earthy, piney OG funk, red hairs that give it the name, and a reputation as one of the stronger OG strains. Its leading terpenes are myrcene, limonene and β-caryophyllene.

What is Fire OG?

Fire OG belongs to the OG Kush family, which traces back to OG Kush's first cultivation in Florida in the early 1990s. Both of its parents are OGs, so it is less a departure from the family than a concentrated version of it: the same fuel and spice character, with more lemon on top.

The name comes from the plant itself. Mature buds carry bright red hairs over a frosty coat of trichomes, and in good light they look like they are smoldering. Leafly's strain data describes it as a favorite with experienced consumers who have a high THC tolerance, and that matches how it is usually talked about: a strain people graduate to, not one they start with.

Fire OG lineage

Fire OG is a cross of two OGs, which is why the family traits come through so clearly.

Parents	OG Kush × SFV OG Kush
Descendants listed on Leafly	Animal Cookies, White Fire OG

OG Kush brings the fuel, skunk and spice the whole family is known for. SFV OG Kush comes out of California's San Fernando Valley OG line, and Leafly notes it is an Afghani-crossed relative of SFV OG, not the same strain. Fire OG keeps that family character, with the lemon pushed to the front. For the wider family, the best OG strains roundup covers the other names worth knowing.

Aroma and flavor

Leafly's data lists Fire OG's flavors as lemon, earthy, pine, woody and citrus, and the aroma is often compared to lemon furniture polish. That polished-lemon note is the first thing most people pick up, with the OG earth and pine underneath.

Our Native® Fire OG blend reads it in more detail. On the nose: cayenned carrots and smoked lemon heads giving way to kumquat and tangerine peel, with undertones of yuzu and quince paste. On the palate: pineapple leaves, wild thyme, dragon fruit and star fruit, finishing warm with sumac, sorrel, saffron and cinnamon bark.

Fire OG terpene profile

Fire OG's terpenes explain why it smells like a cleaner, brighter OG.

• Myrcene is the most common terpene in Leafly's data for the strain. It brings the earthy, musky, herbal base that all OGs share.
• Limonene is the lemon. It is the terpene behind the furniture-polish comparison and the bright top note.
• β-Caryophyllene adds peppery, woody spice, which reads as the fuel edge in the finish.

Smaller amounts of linalool and α-pinene also turn up. In our Native® Fire OG blend, limonene leads, followed by myrcene and β-caryophyllene, which puts the lemon-forward nose at the center of the profile. Terpene levels in flower vary from grow to grow, so a single lab result describes one batch, not the strain.

How people describe Fire OG

Consumer reviews on Leafly most often tag Fire OG as relaxed, tingly and euphoric, and Leafly describes its effects as potent and long lasting. With typical THC around 20%, it has a reputation as a strong strain, and most people treat it as an evening choice rather than something for the middle of the day.

That strength is part of its appeal for brands: Fire OG is a recognizable name that experienced consumers look for, and the lemon-fuel profile stands out on a shelf of earthier OGs.

Recreating Fire OG in a product

The Entour™ Native® Fire OG blend recreates the strain's lemon-led OG character without flower. The strain data card above shows its terpene order and the live price per mL at every size.

Typical starting rates from our application guides are 5 to 15% by weight in vape cartridges, where a bright limonene top note does a lot of the work on the first draw, 0.5 to 2% of the final product in edibles, 0.1 to 0.5% in beverages and 1 to 5% by weight in topicals. Test in your own base before scaling, since distillates and carrier oils change how a profile reads.

To compare it with other OGs, put it in a build-your-own sample pack next to OG Kush and SFV OG. If you are developing a product line, ask us about a custom formulation.
