Yeast SAFBREW S-33 Ref: YEASSAFS33 Ingredients: Yeast (Saccharomyces cerevisiae), rehydrating agent Properties: A very popular general purpose yeast, displaying both very robust conservation properties and consistent performance. This yeast produces superb flavour profiles and is used for the production of a varied range of top fermented special beers (Belgian type wheat beers, Trappist, etc.). Sedimentation: medium. Final gravity: high. Also recommended for bottle-conditioning of beers. Excellent performance in beers with alcohol contents of up to 7.5% v/v but can ferment up to 11.5% v/v. Dosage: 50 g/hl to 80 g/hl in primary fermentation. 2.5 g/hl to 5.0 g/hl in bottle-conditioning. Pitching instructions: Re-hydrate the dry yeast into yeast cream in a stirred vessel prior to pitching. Sprinkle the dry yeast in 10 times its own weight of sterile water or wort at 27C ± 3C. Once the expected weight of dry yeast is reconstituted into cream by this method (this takes about 15 to 30 minutes), maintain a gentle stirring for another 30 minutes. Then pitch the resultant cream into the fermentation vessel. Alternatively, pitch dry yeast directly in the fermentation vessel providing the temperature of the wort is above 20C. Progressively sprinkle the dry yeast into the wort ensuring the yeast covers all the surface of wort available in order to avoid clumps. Leave for 30 minutes and then mix the wort e.g. using aeration. Fermentation temperature: Recommended fermentation temperature: 15C – 24C. Packaging: 500 x 10g nitrogen-flushed sachets in cardboard box. 20 x 500g vacuum-packed sachets in cardboard box. 1 x 10 kg vacuum-packed sachets in cardboard box. Storage: Store in cool (< 10C), dry conditions. Opened sachets must be sealed and stored at 4C and used within 7 days of opening. Do not use soft or damaged sachets. Shelf life: Refer to best before end date on sachets. 24 months from production date under recommended storage conditions. Typical analysis: % dry weight: 94,5 - 96,5 Viable cells at packaging: > 6 x 109/gramme Total bacteria*: < 5/ml Acetic acid bacteria*:*: < 1/ml Lactobacillus*: < 1/ml Pediococcus*: < 1/ml Wild yeast non Saccharomyces*: < 1/ml Pathogenic micro-organisms: in accordance with regulation *when dry yeast is pitched at 100 g/hl i.e. > 6 x 106 viable cells /ml Important notice: Please note that any change to a fermentation process may alter the final product quality. We therefore advise that fermentation trials are carried out prior to using our yeast commercially.
