COURSE CONTENT

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

1. Demonstrate understanding of important steps in the process and science of red, white, sparkling and dessert winemaking.

2. Relate basic principles of wine chemistry and microbiology to the production of wine.

 

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.
