Taste & Aroma



Terpene profile
Myrcene, Pinene dominant

Emerald Mountain Legacy presents Oil Spill, a superb cannabis hybrid that combines two legendary varieties of cult status in Cali’s Emerald Triangle: XXX OG and Royal Kush.

The XXX OG has a wonderful pedigree, coming from OG Kush and Chemdog, and Mandelbrot’s Royal Kush is arguably the finest strain he ever created. It’s still amongst Cali’s most sought-after strains today.

Expect strong, vigorous plants with crystalline layers of glistening trichomes. Oil Spill has a mind-blowing potency that is not recommended for novices and an incredible terpene profile that showcases the powerful fuel and rubber notes with fruity undertones. A very special strain.

Emerald Mountain Legacy is dedicated to preserving and continuing the work of Mack Anderson, better known as Mandelbrot or Ras Truth, who is renowned for bringing diesel fuel genetics to Northern California’s Emerald Triangle. After distributing the first clones of OG Kush and Sour Diesel in Humboldt County, Mandelbrot developed his own cultivars that became so widely propagated they are now esteemed as the foundation for the Emerald Triangle’s world-famous gasoline-scented high-grade. EML’s rare and exclusive genetics continue to be popular and feature strong resin production, high yields and astonishing terpene profiles.
