CellarScience® Slayer 800 | High-Gravity Nutrient for 18-20% Alcohol Ferments

Fermenting a sugar wash to 20% ABV demands precision, not brute force. At this level, osmotic pressure, ethanol toxicity, and nutrient exhaustion push yeast to their absolute limits. Conventional high-output nutrients rely on aggressive nitrogen overloads that drive speed at the cost of flavor, producing the harsh, chemical off-notes familiar to high-gravity makers.

Slayer 800 was engineered to defeat that problem, enabling rapid, stable, and neutral fermentations that finish strong, clean, and predictable. Precisely calibrated for washes targeting 18 to 20% ABV, its nutrient ratio is expertly tuned to balance nitrogen availability, osmotic stress, and overall yeast health.

The Science Behind the Clean

Every component in Slayer 800 serves a precise biochemical purpose:

• Dual-Phase Nitrogen System: Combines rapid inorganic nitrogen for early growth with a measured organic fraction that sustains amino-acid synthesis deep into fermentation. This prevents nutrient collapse while minimizing fusel and sulfur formation.

• Buffered Mineral Stability: A robust mineral-based buffering system moderates acidification and preserves yeast metabolic efficiency.

• Micronutrient Reinforcement: Supported by bioavailable zinc, magnesium, and an optimized vitamin complex, Slayer 800 reinforces cell-wall integrity and alcohol-dehydrogenase activity—the critical pathways that allow yeast to survive and thrive at extreme gravities.

The result is a wash that ferments completely without the off-flavors or volatility typical of over-stimulated nutrient blends.

Versatility & Compatibility

• Remarkably Neutral Base: The purity of a Slayer 800 fermentation yields a clean canvas. It can serve directly as a 20% alcohol base or be diluted into a lower-strength seltzer base without introducing residual yeast or flavor carryover.

• Broad Strain Compatibility: Compatible with a wide range of distiller’s and specialty yeast strains, Slayer 800 delivers complete, stable finishes from small-batch runs to large-scale production.

Key Features

• High-gravity specialization: Tuned specifically for 18–20% sugar-wash fermentations.

• Neutral, clean profile: Suppresses fusel, sulfur, and solvent-like off-compounds.

• Science-driven formulation: Developed through extensive trials for maximum speed and purity.

Dosage & Packaging

• Batch Sizes: Available in convenient pre-measured packs (25 g for 2 gallons; 63 g for 5 gallons) as well as 1-lb and 5-lb bulk options.

• Commercial Rate: For large batches, the recommended dosage rate is 12.5 g per gallon or 13.7 oz per bbl.
