White Labs Ferm Flask

White Labs Ferm Flask by Sabco Product Details

Maintaining vital yeast cultures is the key to a consistent and flawless fermentation. Contamination in the brewery, caused by bacteria, wild yeasts and other microbiological organisms is largely a results of poor yeast handling, storage, and transfers. Because this vessel is entirely enclosed and completely sanitary it provides a simple way to avoid contamination in the brewery and will prevent the spread of contaminants and beer spoilage organisms.

The inspiration for the White Labs Ferm Flask is the Carlsberg Flask and Emil Christian Hansen's creation of the first pure yeast culture in 1883. Just like the Carlsberg flask or the past, this yeast brink was developed specifically for aseptic yeast handling in the brewery, assuring a pure and physiologically fit pitching yeast. Produced in cooperation with Sabcokegs.com Ltd. we employ smooth and sanitary weld techniques throughout this vessel. In keeping with the Danish roots of the Carlsberg flask, Troels Prahl has modified the design of this flask to meet and surpass industry standards for yeast handling. This flask combines the ingenuity of Hansen with modern features demanded by breweries of all sizes.
