Course Contents

  1. Students will learn to use a basic titration kit to evaluate and adjust their brewing water ion content to appropriate levels for different styles of beer.
  2. Students will learn how to properly handle and operate a compound microscope.
  3. Students will learn how to calculate viable yeast counts and use this information to adjust brewing techniques.
  4. Students will grow bacteria and yeast using a variety of methods such as slant to slant transfer, slant to broth transfer and streak plate for isolation.
  5. Students will learn the basic processes for long term storage of bacteria and yeast in the -80 degree freezer.
