Deltabrew® PURE

Brewing enzyme used to prevent haze formation in beer.

Product Specs

Acid-stable endo-exo protease developed from a non-GMO strain of Aspergillus niger to prevent haze formation caused by the association of proteins and phenolics during cold storage (“chill haze”). Helps increase shelf-life, improves clarity, and positively affects foam stability. Can be used to reduce or replace your traditional stabilizers for a more “natural” approach to stabilization.

        • Active at 0–20oC
        • Deactivated during pasteurization 62–75oC.*
        • Little to no affect on foam or flavor.
        • Non-GMO, vegan-friendly, and kosher.

                *Optimization of PUs (Pastuerization Units) needed to inactivate the enzyme recommended.

Application: Add at 1–4 mL/hL in cooler temperatures such as during fermentation, maturation, or later in the bright beer tank before bottling.

Packaging: 1 kg, 5 kg, 25 kg

Figure 1 — Deltabrew® Pure dosage-dependent stability** (according to MEBAK II and foam stability** (according to MEBAK II 2.18.4) of an unstabilized, unfiltered/cloudy beer. Stability of the beer increases linearly with the dosage. Addition of Deltabrew® Pure has no negative effect on foam stability.
