Frequently Asked Questions
What temperature should I ferment GV12 at?
The ideal fermentation temperature for GV12 is 18–22°C. Fermenting below 15°C will slow or stall fermentation. Above 24°C can produce fruity esters and fusel alcohols. A stable temperature within the ideal range produces the cleanest, best-tasting results. See our fermentation temperature guide.
How long does GV12 take to ferment?
At 18–22°C, primary fermentation is typically complete in 7–10 days. Always confirm with a hydrometer — two identical gravity readings 24 hours apart means fermentation is complete. Don't rush it; leaving the beer on yeast an extra few days improves clarity and flavour.
Can I use GV12 instead of the yeast included with my beer kit?
Yes — GV12 is an excellent upgrade over most kit yeasts. Kit yeasts are often basic strains chosen for reliability over flavour. GV12 produces a cleaner, more flavourful fermentation and is particularly recommended for Coopers, Muntons, Woodforde's and St Peters kits.
Does GV12 work for all ale styles?
GV12 is very versatile and works well across most British and American ale styles — pale ales, IPAs, bitters, stouts, porters, amber ales and golden ales. For Belgian, wheat, or highly specialised styles, a specific strain would give more authentic results.
Do I need to rehydrate GV12 before pitching?
You can sprinkle GV12 directly onto the wort surface (dry pitching) or rehydrate it first in warm water (30–35°C) for 15 minutes before adding. Rehydrating improves yeast viability slightly and is recommended for higher-gravity beers above 1.060 OG.
