Fermentis Safale S–04 is a robust English ale yeast known for its fast fermentation and ability to produce well–balanced ales. It is ideal for crafting beers with a rich, malty character and excellent clarity, making it a favorite for traditional English styles such as bitters, stouts, and porters. The yeast produces minimal diacetyl, ensuring a clean and crisp final product.

This yeast strain settles rapidly, forming a compact sediment at the bottom of the fermenter, which simplifies beer clarification. Its fermentation profile enhances fruity esters and subtle flavors, characteristic of classic British ales. The 11.5 g packet is perfectly portioned for homebrewers, offering consistent results with every batch.

Whether you’re brewing a classic English ale or experimenting with malt–forward recipes, Safale S–04 provides versatility and reliability, elevating the quality of your homebrew.
