Reduce saccharification time, break down starches in unmalted cereals, and increase attenuation with one simple product! Ultra-Ferm from White Labs is a highly concentrated liquid amyloglucosidase derived from a select strain of Aspergillus niger. Rather than acheiving 75 to 80% hydrolisis of present starches, as you would with traditional brewing methods, Ultra Ferm allows total hydrolisis of dextrins to fermentable glucose, from all types of starch.
UltraFerm WLN4100 makes for the perfect additive when brewing a Brut IPA or Champagne Beer by eliminating residual sugar, allowing you to acheive the dry flavor profile that is signature to the style. It can also be used for the production of low calorie and extra high-alcohol beers, as well as light or diatetic beers.
Add at the beginning of the mash-in. Ultra-Ferm optimal pH is between 3.5 and 5.5. Temperature should not exceed 140°F. Amyloglucosidase activity is completely destroyed when the wort is held at 185°F for 10 minutes.
We've experimented with adding this enzyme at different stages throughout the brewing process, and found that it isn't limited to the mash stage alone. When pitching Ultra Ferm alongside our yeast, we were able to achieve a final gravity of 1.000, with no negative effect on the finished beer. Great news for the extract brewers out there that want to produce an extra dry beer!
