PRR-500BCE is a unique brewing yeast strain that was excavated from the Ramat Rahel archaeological site in Jerusalem, Israel. The strain has been identified as Persian, dating back to the 5th century BCE.

This yeast strain has been found to be a genetic relative of traditional Ethiopian Tej and therefor is particularly well-suited for mead fermentation, as it has a high alcohol tolerance and produces a wide range of esters. These esters are characterized by a strong red apple flavor and aroma, which can contribute to the unique character of your mead.

With its high attenuation degree and high flocculation, PRR-500BCE is an excellent choice for brewers looking to create a high-quality, flavorful and clear mead with consistent results. Whether you are a professional brewer or a home-brew enthusiast, this yeast strain can help you achieve the perfect balance of flavor and aroma in your mead.
