London Fog
Unknown × Unknown
London Fog is an indica-dominant cannabis cultivar recognized for its distinctive aroma and flavor, reminiscent of the creamy Earl Grey tea beverage. It is characterized by dense, resinous flowers and a balanced yet potent effect profile, making it a popular choice among connoisseurs.
Appearance
London Fog typically presents with medium-sized colas that feature compact calyxes and significant resin coverage, giving them a frosted appearance. The buds display colors ranging from lime to deep green, often with violet hues, complemented by bright orange or copper pistils. The structure is generally indica-leaning, with moderate spacing between nodes and robust branching.
The flowers are dense and can appear rounded or chunky due to swollen bracts. Even after drying and curing, the high trichome density results in a tacky texture. Despite their size, the top colas can be quite heavy, contributing to substantial yields in well-managed cultivation environments.
Aroma & Flavor
The aroma of London Fog is a complex bouquet that mirrors its namesake beverage, featuring notes of citrus, particularly bergamot, intertwined with soft floral scents like lavender. Underlying these top notes is a sweet, creamy base, often with subtle hints of vanilla and baking spice. Upon grinding, these aromas intensify, releasing a bright, zesty citrus and floral fragrance that is both inviting and distinct.
On the palate, London Fog delivers a bright, citrus-forward inhale, often described as bergamot and orange, followed by gentle lavender notes. The experience evolves into a softer, creamier mid-palate with impressions of vanilla and light pastry. The exhale is typically smooth and sweet, with a lingering floral quality and a mild peppery warmth, especially when properly cured.
Effects
London Fog is known to produce a balanced yet potent high, often described as calming and relaxing. The effects tend to be more indica-leaning, promoting a sense of tranquility and ease without being overly sedating. This makes it suitable for unwinding and de-stressing.
Terpenes & Cannabinoids
The terpene profile of London Fog is commonly led by limonene, contributing citrus notes, and linalool, responsible for floral and lavender aromas. Beta-caryophyllene often adds a warm, spicy undertone, while humulene and bisabolol can contribute herbal and creamy characteristics, respectively. Some phenotypes may also exhibit faint minty or eucalyptus notes.
Contemporary batches of London Fog typically exhibit high THC levels, frequently ranging from 18% to 26%, with some exceptional phenotypes potentially exceeding this. Total cannabinoid content generally falls between 20% and 30% when minor cannabinoids are accounted for.
Growing
London Fog is considered a boutique cultivar, and its cultivation requires attention to detail, particularly regarding airflow in the later stages of flowering due to its dense bud structure. Growers should aim for a patient dry and a slow cure, typically involving 10-14 days of drying followed by 3-6 weeks of jar curing, to preserve its delicate aromatic compounds and ensure a smooth smoke.
The plant structure is generally hybrid-indica leaning, with moderate internodal spacing and robust lateral branching. It is known for producing dense, trichome-heavy flowers that contribute to its appealing bag appeal and above-average yields when grown under optimal conditions. Maintaining proper humidity levels is crucial to prevent issues associated with dense flower clusters.
Origins & Lineage
The exact genetic lineage of London Fog is not publicly documented, with many growers listing it as proprietary or unknown. However, its sensory profile and morphology suggest potential ancestry within the dessert-cookie and sherbet families, possibly crossed with a floral-leaning strain. Hypotheses include crosses involving Gelato, Sunset Sherbet, or London Pound Cake, often with a lavender-scented cultivar.
The cultivar emerged in North American boutique dispensaries and private circles in the late 2010s and early 2020s, coinciding with a trend towards dessert-forward genetics. Its name and flavor profile, evoking Earl Grey tea with milk and vanilla, have contributed to its popularity and word-of-mouth growth. It is often appreciated for its bag appeal, characterized by dense, frosty flowers and a distinctive aroma.
