Fermentis | Safcider™ Ac-4 | Dry Cider Yeast

As a home brewer or professional beverage maker, you understand the importance of using high-quality yeast to produce exceptional cider. That's why Fermentis, a renowned name in the industry, offers Safcider™ AC-4, a dry cider yeast designed to deliver outstanding results. This premium yeast strain is specifically formulated to produce fresh and crisp cider with an intensely fresh aromatic profile, characterized by notes of apple and floral hints. The resulting cider boasts a crisp mouthfeel, perfectly balanced to enhance the overall structure of the beverage.

What sets Safcider™ AC-4 apart from other cider yeast strains is its ability to thrive in a wide range of fermentation conditions, making it an ideal choice for both sweet and dry ciders. Its excellent settlement strength ensures a reliable fermentation process, even in challenging environments. Additionally, this yeast strain is sensitive to killer phenotype, allowing it to coexist peacefully with other microorganisms in the fermentation tank.

One of the key benefits of using Safcider™ AC-4 is its broad fermentation temperature spectrum, ranging from 10°C to 30°C (50°F to 86°F). This versatility makes it suitable for a wide range of cider production scenarios. Furthermore, this yeast strain has low nitrogen requirements, making it a practical choice for brewers who want to minimize their input costs.

In terms of technical characteristics, Safcider™ AC-4 exhibits fast kinetics, allowing it to quickly ferment sugars and produce a high-quality cider. Its ability to assimilate fructose efficiently ensures a smooth fermentation process, while its low malic acid consumption (less than 0.4 g/L) helps preserve the natural characteristics of the apples used. As a medium producer of 2-phenylethanol and isoamyl acetate, this yeast strain contributes to the cider's complexity and aroma. Finally, its high production of ethyl (fruity) esters adds a delightful fruity flavor to the finished cider.

To ensure optimal results, Fermentis recommends using Safcider™ AC-4 at a dosage of 10 to 20 g/hl for the first fermentation and 30 to 40 g/hl for the prise de mousse stage. For direct inoculation, simply pour the yeast onto the surface of at least 10 times its weight of must, gently stir to avoid breaking clumps, and transfer the mixture into the tank via a pumping over with aeration. Alternatively, you can rehydrate the yeast by mixing it with 10 times its weight of tap water at room temperature, wait for 20 minutes, and then transfer it to the tank.

With a shelf life of 4 years from the production date, Safcider™ AC-4 is a reliable and consistent choice for cider makers who demand the best results. Whether you're a seasoned brewer or an enthusiast, this dry cider yeast is the perfect addition to your toolkit. With its exceptional performance, ease of use, and versatility, Safcider™ AC-4 is the go-to choice for producing world-class cider.
