Science of Winemaking I - Oenochem


Credits: 5
Clock Hours per Quarter: 60

Lecture Hours:40    Lab Hours:20


Description
This is an advanced enology course open only to students enrolled in the Enology and Viticulture program. The purpose of this course is for students to learn the fundamental biochemistry needed for the winemaking process. Topics include the metric system, concentrations, mineral ions, molecules, equilibria, acid-based chemistry, and oxidation-reduction reactions. Online homework, two laboratory activities, and two open-note exams required. Prerequisites: Completion of EV 102 with a grade of C or higher and/or Director permission.

Intended Learning Outcomes
  • Differentiate mass from moles.
  • Perform metric conversions.
  • Perform density and concentration calculations, including percent by mass and volume, proof, molarity, and normality.
  • Recognize and name mineral ions and simple organic compounds.
  • Recognize line drawings of the major organoleptic functional groups appearing in wine, including the major organic acids.
  • Apply the pH scale and neutralization reactions to the fermentation process.
  • Differentiate amino acids, proteins, and enzymes.
  • Differentiate alcohols, simple sugars, and complex carbohydrates.
  • Describe the anaerobic glycolytic pathway that yeast uses to produce ethanol.

  • Course Topics
  • Chemical nomenclature.
  • Periodic Table.
  • Mass and moles.
  • Density, specific gravity, Brix, Baume, Oechale scales.
  • Percent by mass and volume, proof, molarity and normality.
  • Ions and molecules.
  • Organic line drawings.
  • Hydrophilic versus hydrophobic compounds.
  • Functional groups for taste and olfaction.
  • Reversibility and oxidation-reduction reactions.
  • The pH scale and acid-base reactions.
  • Organic acids, conjugate bases, and buffers.
  • Amino acids, proteins, and pectinase.
  • Simple versus complex carbohydrates.
  • Aerobic versus anaerobic fermentations.
  • Enology as one of many possible fermentations.
