 What is dried yeast?
Basically, certain strains of liquid yeast are dried under vacuum to produce a concentrated granular yeast product.
 Why should I use dry yeast?
- One packet is enough to inoculate 5 gallons of wort.
- Shelf life is measured in years.
- Less expensive than liquid yeast.
- Less susceptible to mishandling than liquid yeast.
- Can often be directly pitched by sprinkling on the cooled wort in the fermenter without rehydrating or making a starter.
- Less variety of strains
 Dry Yeast Strains
- Muntons Premium Gold Ale
- One of the best English Ale yeasts. Use 2 packs in 5 gallons of wort.
- Muntons Standard
- As the name implies, a good all-around general ale yeast.
- Danstar Belle Saison
- This fruity Belgian Saison yeast has high attenuation and high tolerance for alcohol. (Belle Saison Datasheet)
- Danstar BRY-97
- This American West Coast Ale yeast has high flocculation and a slightly estery profile. (BRY-97 Datasheet)
- Danstar Diamond Lager
- This German lager yeast is only available in 500 gram packages from the manufacturer. (Diamond Lager Datasheet)
- Danstar Nottingham Ale
- English strain noted for producing clear beers. The Nottingham strain was selected for its highly flocculant (precipitating) and relatively full attenuation (transforming sugar into alcohol) properties. It produces low concentrations of fruity and estery aromas and has been described as neutral for an ale yeast, allowing the full natural flavor of malt to develop. Good tolerance to low fermentation temperatures, 14°C (57°F), allow this strain to brew lager-style beer. Recommended 14° to 21°C (57° to 70°F) fermentation temperature range. (Nottingham Datasheet)
- Danstar Windsor English Ale
- This yeast strain is traditional for Brown Ales. Danstar Windsor ale yeast originates in England. This yeast produces a beer which is estery to both palate and nose with a slight fresh yeasty flavor. These are usually described as full-bodied, fruity English ales. Depending on the substrate, the Windsor demonstrates moderate attenuation which will leave a relatively high gravity (density). Recommended 17° to 21°C (64° to 70°F) fermentation temperature range. (Windsor Datasheet)
- Safale S-04
- Whitbread strain famous for its excellent attenuation and flavorful profile. (S-04 Datasheet)
- Safale T-58
- Estery, spicy & peppery flavors in wheats and speciality ales, very solid sediment. (T-58 Datasheet)
- SAF ALE US-05 (formerly US-56) American Ale (Chico Strain)

- This wheat beer yeast has low flocculation. Substitutes for WL3333 or WLP-380. (WB-06 Datasheet)
- Brewferm Lager
- Very clean lager yeast, delivering consistent neutral fermentation with little or no sulphur components and other undesirable by-products. Substitutes for WL2565 or WLP-003.

- This wide-temperature yeast was developed from traditional Champagne yeasts, but can be used in a wide variety of wines due to its neutral flavor. (EC-1118 Datasheet)
