Red Star Premier Blanc, also known as Pasteur Blanc or UCD #595, is a versatile and robust strain of yeast commonly used in the production of white wines. This particular strain is not typically used in the production of sparkling wines or champagnes.
One of the key characteristics of Red Star Premier Blanc is its ability to tolerate sulfites, which are commonly used as a preservative in winemaking. This is an important quality, as it allows winemakers to use sulfites to protect their wines from spoilage without negatively impacting the yeast fermentation process.
In terms of fermentation, Red Star Premier Blanc is known for its moderate foaming properties, which can be beneficial in certain winemaking applications. The yeast is also able to perform well within a wide temperature range, typically between 59 and 86 degrees Fahrenheit. This flexibility allows winemakers to adapt their fermentation conditions to achieve the desired flavor and aroma profiles in their white wines.
One notable characteristic of Red Star Premier Blanc is its ability to impart a pleasant yeasty flavor to the finished wine. This can add complexity and depth to the overall sensory experience of the wine, enhancing its overall appeal to consumers.
In my personal experience as a sommelier and brewer, I have found Red Star Premier Blanc to be a reliable and consistent yeast strain for white wine production. Its sulfite tolerance and versatile fermentation properties make it a popular choice among winemakers looking to create high-quality white wines with distinct flavors and aromas.
Red Star Premier Blanc is a highly regarded yeast strain in the winemaking community. Its all-purpose nature, vigorous fermentation properties, and ability to tolerate sulfites make it a valuable tool for winemakers looking to produce exceptional white wines.
