This is a Very High Gravity yeast built for high-alcohol scenarios up to ~20% ABV, with aggressive kinetics that keep moving when typical strains start to slow, stress, and produce off-flavors. Reaper is also comfortable running warm, and it’s right at home in real-world distilling temperatures. 75–95°F is a sweet spot for speed and cleanliness.\u003c\/p\u003e\r\n\u003cp\u003e\r\n\tAnd yes, it’s called Reaper for a reason.

Pair Reaper with CellarScience Slayer 800 to give the yeast the nutrition it needs to stay healthy under high-gravity and high-alcohol conditions. The combination helps Reaper ferment fast and steadily while keeping unwanted fermentation byproducts in check.\u003c\/p\u003e\r\n\u003cp\u003e\r\n\t\u003cstrong\u003eA Clean Base You Can Actually Use.

Ferment clean, dilute down to your target hard seltzer strength, carbonate, and flavor. The same high-gravity capability that makes Reaper useful for distillation makes it possible to produce a clean base efficiently and take it in several different directions.\u003c\/p\u003e\r\n\u003cp\u003e\r\n\t\u003cstrong\u003eDosage:\u003c\/strong\u003e\u003cbr\u003e\r\n\tOne 15-gram sachet treats approximately 5 gallons of wash.
