Objectives:

At the conclusion of this course, the student should be able to:

1. Understand basic principles of viticulture to make harvest decisions and effectively discuss vineyard practices with viticulturalists.

2. Identify, describe, and make educated choices about each step in the winemaking process.

3. Describe the basic chemistry of important wine components including acids, sugar, alcohol, phenolic compounds, sulfur dioxide and flavor compounds.

4. Compare and contrast the microbes that impact wine, including yeast, malolactic bacteria, and spoilage organisms.

5. Develop a plan to produce a premium wine.

6. Perform wine lab assays used in small to medium-size wineries, and evaluate results.
