- Source Notes:
- November 2019, Vol. 25, No. 7 page 17. First off, use high-quality, fresh ingredients with an emphasis on UK-based malts and hops if possible. Consider Crisp, Thomas Fawcett, and/or Simpsons as your maltsters of choice. Next, focus on your fermentation. Ensure your pitch is appropriately sized and healthy; the easiest way is to either repitch yeast from a previous batch of beer or create a starter in whatever way you're most comfortable. This yeast strain has been known to struggle to attenuate to this extent, so be sure to provide and ideal environment with proper temperature control to ensure a strong fermentation. Finally, focus on water chemistry for a malt-forward beer. To this end, ensure you have at least 40 ppm of calcium in the brewing water but more importantly your ratio of chloride-to-sulfate should be in the range of 1:1 to 2:1. With great base ingredients that are well-attenuated and flavored appropriately with the right amount of ions, you should have no trouble brewing an amazing Scottish 90/-.
- Notes:
- Bring 6.5 gallons of water to roughly 150F. Steep all the specialty malts 15 minutes before removing and draining. Add the extract, while stirring, before heating to a boil. Boil for 60 minutes, adding hops at the indicated times left in the boil. At 15 minutes left in boil, you may want to add either Irish moss or Whirfloc as fining agents. After the boil, add the whirlpool hops indicated and whirlpool for 15 minutes before rapidly chilling the wort to 66F. Pitch yeast and aerate the wort. Maintain fermentation temperature of 68F for this beer. Once the primary fermentation is complete, and the beer has settled, bottle or keg the beer and carbonate to approximately 2.5 volumes.
