The Scientific Brewer Series
Discover how one sulfur compound could be ruining your beer - and how the Quantum Series eliminates it for good. This white paper reveals the science behind DMTS, the "cabbage bomb" of brewing, and how to stop it before it starts. Better flavor, more consistency, zero compromise.

What is DMTS?
DMTS is a volatile sulfur compound (VSC) that gives off a "rotten cabbage" or overcooked vegetable aroma.
It has an extremely low flavor threshold, so even trace amounts can ruin a beer's flavor.

Why is DMTS a Problem in Brewing?
It can form naturally during hop processing or be introduced during cold-side additions like dry hopping.
Many hop extracts created with CO2 extraction, steam distillation, or other high-heat methods concentrate DMTS rather than eliminate it.
Once beer is cooled post-fermentation, there is no natural mechanism to remove or volatilize DMTS, so it lingers.

What Makes Quantum Different?
Quantum Series extracts are engineered to be free of DMTS and other sulfur-based off-notes.
Abstrax uses proprietary low-temperature extraction methods that selectively include desirable compounds while excluding DMTS.
The Abstrax process preserves desirable thiols (like 3S4MP and 4MMP) that add tropical and citrus notes without the vegetal byproducts.

Study and Testing
Abstrax conducted a chemical and sensory comparison between its Quantum Series and two leading commercial hop extracts
A blind sensory panel confirmed that only the Quantum sample avoided sulfur off-notes while maintaining bright, clean hop character.
