King Louis Strain Review: Effects, THC & OG Kush Genetics

Few strain names carry as much old-school weight as this one. In this King Louis strain review, we look at where King Louis (also sold as King Louis XIII) comes from, what it smells and tastes like, how it hits, and who should reach for it — so you can decide if this dense, trichome-heavy indica belongs in your next order.

King Louis Strain Genetics

King Louis XIII is widely regarded as a phenotype selection out of the OG Kush family line. Exact breeder records for older OG Kush-derived cuts like this are notoriously murky — much of the West Coast OG lineage was passed around informally in the 1990s and 2000s before anyone was tracking pedigrees — but King Louis is consistently described as OG Kush royalty: dense, resinous, and unmistakably kush in structure and smell. That heritage is exactly what shows up in the jar, from the tight bud structure to the heavy trichome coating.

Aroma & Flavour

Break apart a bud of King Louis and you’re greeted with sharp pine and damp earth up front, backed by a deeper, almost peppery kush funk. There’s a subtle sweetness underneath if you look for it, but this is fundamentally a savoury, old-school strain profile rather than a fruity or dessert-forward one. On the exhale, expect a heavy, resinous kush flavour that lingers — a flavour that OG Kush fans will recognize instantly.

Terpene Profile

King Louis leans on a terpene profile dominated by myrcene and caryophyllene, which explains both the peppery earthiness and the heavy, sedating body feel. A touch of limonene rounds out the pine-citrus edge you get on the inhale.

Effects: What to Expect

King Louis is built for nighttime. The onset is relatively quick for an indica — within a few minutes you’ll feel a gentle mental fog settle in, followed by a wave of physical relaxation that spreads from the head down through the body. This isn’t a strain that leaves room for productivity; it’s designed to switch your brain off and get you comfortable. Expect:

• A quick, noticeable mental unwind in the first 5-10 minutes
• Heavy-eyed, full-body relaxation that deepens over the session
• A strong sedative pull well-suited to the couch or the bed
• Minimal cerebral stimulation — this is a body strain, not a head strain

Typical THC Range

As an AAA-grade indica, King Louis generally tests in the 18-24% THC range. That’s a solid, dependable potency for an OG-lineage strain, strong enough to deliver real sedation without requiring an oversized dose.

Who King Louis Is For

King Louis is best suited to:

• Experienced indica consumers who already know they respond well to heavy, OG-style genetics
• Insomnia and sleep support — this is very much an end-of-day, lights-out strain
• Chronic tension or discomfort where a strong, full-body relaxant is the goal
• OG Kush fans looking for a classic pine-and-earth profile over sweeter, dessert-style flower

Because King Louis hits fast and heavy, it’s not the best pick for a daytime session or anything that requires focus afterward. Clear your evening, keep the lights low, and let the strain do what it was bred to do.

How to Enjoy It

A dry pipe or bowl lets the pine-and-kush aroma come through clearly, while a joint offers a slower burn if you want to stretch the session out. Given how strong the sedation can get, pace your sessions — a small bowl an hour before bed goes a long way with King Louis.
