Oxygen is the brewer’s worst enemy. It can turn a bright, explosive IPA into a dark, cardboard‑tasting drink in just a few weeks. While traditional solutions help, Stop Redox completely changes the game. It is the ultimate solution for anyone who wants a beer that stays fresh, bright, and aromatic month after month.
1. Why is Stop Redox a revolution?
Unlike traditional antioxidants that are often added too late (at bottling), Stop Redox acts right from the beginning of the process. It is a complex blend of antioxidants and reducing agents that hunts down dissolved oxygen before it can damage your raw materials:
- Aroma protection: It captures free radicals that “eat” hop essential oils and terpenes.
- Color stability: It prevents premature browning (melanoidin formation) in pale beers such as NEIPAs or Pilsners.
- Long‑lasting action: Its formulation allows it to continue protecting the beer even once packaged in bottles or kegs.
2. A tiny dose for maximum impact
The effectiveness of Stop Redox lies in its extreme concentration. While other products require large amounts, only a tiny quantity is enough to secure your batch:
- Dosage: Only 2 to 4 grams per 100 liters of wort (about 0.5 g for a standard 20 L batch).
- Ideal timing: Add it directly to the mash water for full preventive protection.
