    Strisselspalt

    French variety related to Hallertauer.

  • 1 tsp Irish Moss - (omitted from calculations)

    Irish Moss

    A dried red-brown marine algae. Fining agent to remove large proteins. Negatively charged polymer attracts positively charged protein-tannin complexes (extracted from grain husks and hops) during the boil. This action is aided by the clumping of proteins in the boiling process. Irish moss settles to the bottom of the brew kettle with spent hops and hot break material at the end of the boil.

  • Fermentis S-23 Saflager S-23

    Fermentis S-23 Saflager S-23

    This bottom fermenting yeast is originating from the VLB (Berlin) in Germany and is known under the code RH. The strain is used by Western European commercial breweries and has been reported to produce lagers with some fruity and estery notes. Sedimentation: high. Final gravity: medium. 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 23C ± 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.

Good beer with 1 years of aging

This recipe has turned out very good with 1 years of aging. It has one several awards over the past year, but it took about a year to finally mature.
