Popularly called “Chico,” West Coast Ale I is a reliable, versatile and popular neutral foundation for displays of malts and hops. Often used as a house strain, it is highly attenuative and moderately flocculent. And it ferments crisp and clean with light citrus notes under 66° F (19° C). Also try DIPA (OYL-052) or British I (OYL-006) to highlight hops more, or West Coast II (OYL-009) and Scottish Ale (OYL-015) for malt displays.

  • Strain Type:Ales
  • Flocculation: Medium-Low
  • Attenuation: 73-80%
  • Temperature Range: 60–73° F (16–23° C)
  • Alcohol Tolerance: 11%

    Bag arrived with a little swelling (not unusual for chico strains), and kept cool till use. Warmed for 4 hours, pitched at 65F and I had bubbles in the airlock within 12 hours. No starter needed < 1.070 OG.
