Home Brew Yeast Guide — Which Yeast to Use and Why
Share
Which yeast should you use for home brewing?
For most UK ale kits, Gervin GV12 Ale Yeast is our top recommendation — a versatile, reliable top-fermenting yeast that produces clean, well-rounded results across pale ales, bitters, IPAs, and stouts. For stuck or sluggish fermentations, use Gervin GV7 Restart Yeast. See our home brew FAQ for common yeast troubleshooting questions.
What is the difference between ale yeast and lager yeast?
Ale yeasts are top-fermenting and work best at 18–24°C — they produce results more quickly and work at room temperature, making them the practical choice for most home brewers. Lager yeasts are bottom-fermenting and work best at 8–14°C, producing the clean, crisp character of commercial lagers but requiring cooler temperatures and longer conditioning times. Most home brew lager kits use ale-temperature yeast strains that produce a lager-like result without cold fermentation.
What are the best ale yeasts for home brewing?
For British ales, bitters, and stouts, Gervin GV12 Ale Yeast is an outstanding all-rounder. Young's Dried Active Yeast is a versatile 100g tub that covers both beer and low-alcohol wines — excellent value for regular brewers. Both are significant upgrades over the basic yeast included with most budget kits. For more on choosing the right yeast for your style, see our kit improvement guide.
What yeast should I use for wine making?
For home winemaking, dedicated wine yeasts produce far better results than bread or beer yeast. The Young's Dried Active Yeast handles standard wine kits well. For premium wine kits like Beaverdale or WineBuddy 30-bottle, use the yeast supplied with the kit — it's selected specifically for that grape concentrate. Add Yeast Nutrient for healthier fermentation in high-gravity or fruit wines.
What should I do if my fermentation has stopped early?
First check temperature — below 15°C will stall most yeasts. Warm the fermenter to 20–22°C and wait 48 hours. If gravity is still above the expected final gravity after rewarming, add Gervin GV7 Restart Yeast with a teaspoon of Yeast Nutrient.
