. Practicum sites throughout the state are listed on the VESTA website. New ones can be added if the student finds a willing and eligible vineyard.
. Some courses have a minimum age requirement.
. Further information on VESTA can be found on the website

Program Outcomes

. Examine grape samples to ascertain sweetness and acidity of crop, and determine harvest time based off of this information.
. Select yeasts for fermentation and barrels for aging.
. Communicate with vineyard manager regarding crop load, harvest time, and other issues related to crop quality.
. Correct sugar and acid levels of must and wine if necessary.
. Oversee primary fermentation by punching down the grape skin cap, regulating fermentation temperature and the amount of time the skins are in contact with the must, and initiating malolactic fermentation.
. Supervise workers in crushing and pressing processes, or perform those duties themselves.
. Supervise cellar operations during secondary fermentation with tasks such as aging, topping off barrels, and clearing wine of fermentation residue.
. Direct and coordinate blending and bottling of wine, or perform those duties themselves.

Requirements for Program Entry

. Completed application.
. High school transcript or equivalent. (For a list of equivalents, go to
. Students should have mastered basic math skills. For a description of basic math, see the Basic Education section of this catalog.
. As a requirement for program entry, an Academic Skills Assessment (Compass) with appropriate benchmark scores is necessary. Program Benchmarks are Algebra: 45; Reading: 70; Writing Skills: 74. Students not meeting these benchmarks or the equivalent will be required to establish an individualized academic plan. Students may have the opportunity to enroll in selected program core courses while completing their individualized plan. Upon completion of the plan, students will be eligible for all program courses. However, higher test scores will lead to greater success in core program courses.
