Brew authentic Irish ales and robust dark beers with Wyeast 1084 Irish Ale, a premium liquid yeast strain known for its clean attenuation, high alcohol tolerance, and versatile fermentation profile. This classic Irish strain performs exceptionally well in dark worts and high-gravity recipes, producing a dry, crisp finish at cooler temperatures or a richer, fruit-forward character when fermented warmer. Each Wyeast Activator™ pack contains approximately 100 billion cells, providing enough healthy yeast to ferment a standard 5-gallon batch under appropriate conditions. Wyeast 1084 is ideal for brewing Irish Stout, Irish Red Ale, Oatmeal Stout, Baltic Porter, Wee Heavy, and American Barleywine.
Wyeast 1084 delivers balanced fermentation that allows roasted malts, caramel, and specialty grains to take center stage without overwhelming ester production. Cooler fermentations produce a cleaner, drier beer with restrained fruitiness, while temperatures above 64°F (18°C) encourage more complex fruit esters that add depth to stronger ales. Its medium flocculation helps create balanced body while promoting good clarification during conditioning.
This liquid ale yeast features medium flocculation, 71–75% attenuation, and an alcohol tolerance of 12% ABV. It performs best between 62–72°F (17–22°C) and is packaged with approximately 100 billion cells for dependable fermentation performance and consistent brewing results. Its high alcohol tolerance makes it an excellent choice for both sessionable Irish ales and stronger specialty beers.
For best results, store refrigerated between 33–38°F and do not freeze. Pitch cold into well-oxygenated wort and ferment within the recommended temperature range. One Activator™ pack is suitable for many standard-strength 5-gallon batches, while a yeast starter is recommended for higher-gravity beers, older yeast packs, or whenever additional cell count is desired. Cooler fermentations produce a drier, crisper profile, while warmer temperatures develop additional fruity complexity.
Trusted by homebrewers and professional brewers alike, Wyeast 1084 Irish Ale delivers dependable fermentation, excellent alcohol tolerance, and the balanced character expected in classic Irish and high-gravity beer styles. Its healthy cell count, reliable performance, and versatile fermentation profile make it an outstanding choice for brewing flavorful stouts, Irish reds, porters, and strong ales with professional-quality results.
