Different yeast strains contain different enzyme compositions. STA1 positive strains can excrete glucoamylase, freeing glucose and causing hyper-attenuation. While beneficial to Brut IPA, Saison, or low-cal lager, it can lead to over-carbonation and possibly even exploding containers in products with high finishing gravities.
So, which enzyme is right for you? Odds are several can help. When moving through the daily brewing procedures, it is wise to analyze every opportunity for improvement. Look at raw materials to identify any potential headaches before you mash, and include a product like Ondea® Pro to boost mashing potential. Beyond simply unlocking and converting starch, it also releases Free Amino Nitrogen (FAN), an essential component for healthy fermentations. Ondea® Pro can be used in malted barley beers, however the real advantage is the ability to directly convert raw, un-malted barley and other ingredients.
To reduce concerns of poor extraction and improve lautering, consider the use of Ultraflo® Max. Degrading cell wall material like b-glucans and arabinoxylans will lower viscosity and improve physical extraction, particularly in recipes containing large quantities of flaked wheat or rolled oats. Keep that in mind for your next “hazy” IPA!
Another specialty product gaining traction is Attenuzyme® Pro, an enzyme complex that de-branches amylopectin and amylose by way of glucoamylase and pullulanase. Supplementing with Attenuzyme® Pro can decrease mash times while creating a consistent mash composition. Influencing the wort composition will help tailor the fermentation profile, providing more or less esterification, among other subtleties. The “more-complete” breakdown from Attenuzyme® Pro is essential for extremely high attenuating styles, like low-calorie lager, or Brut IPA.
Before you start milling the next batch, take a moment to walk through the process. Are you planning to use all the tools at your disposal? With just a bit of mental effort, you may be able to save on physical labor, raw materials, and time. Couple that with increased output and you’ve got a win-win!
