WLP001

WLP001, also known as California Ale Yeast, is a widely used yeast strain in homebrewing and commercial brewing. It is a strain of Saccharomyces cerevisiae, the common yeast species used for brewing ales. WLP001 is renowned for its clean fermentation profile, producing a balanced and neutral ale flavor. It is characterized by its ability to ferment well at a range of temperatures, typically between 65-75°F (18-24°C).

This yeast strain is known for its reliable flocculation, meaning it settles out of suspension readily after fermentation, contributing to clear beer. Its attenuation, the degree to which it ferments sugars, is moderate, leaving a subtle sweetness in the finished beer. WLP001 is versatile and can be used in a wide variety of ale styles, including pale ales, IPAs, blond ales, and even some lagers if fermented at the cooler end of its range. Its lack of strong or distinctive yeast-derived flavors allows the malt and hop characteristics of the beer to shine through. It is often recommended for beginners due to its forgiving nature and consistent performance. The strain is commercially available from White Labs and is a staple in many brewers' yeast collections.
