Learn to Manage or work in a vineyard
Do you want to start your own vineyard?
- Increase your knowledge of viticulture
- Study horticulture to provide you with a greater depth of knowledge in growing and managing plants and crops.
- A course designed for people working, or intending to work, in grape production.
- The course is structured in two parts - the core units provide a detailed foundation of studies in horticulture, and these are then followed by specialist stream units focusing on the production of grapes for wine, drying, or fresh fruit.
- In addition to assignments throughout the course, to pass the Certificate In Horticulture (Viticulture) students are to sit and pass two exams for the core studies and two for the stream. (Course fees do not include exam fees).
- Options to spread course payments over 4 instalments - the single payment is discounted over the instalment options, in addition, a 5% discount is given for the online study method option.
Course Content and Structure
Half of the course (the Core) provides a broad based foundation that is relevant to both growing grapes or growing any other type of plant. This broad foundation is important in two respects:
- It will give you a broader perspective on the world in which we grow grapes, helping you to appreciate different climates, different techniques, and the science that underpins all good horticulture.
- It will give you the capacity to adapt and earn an income from more than just growing grapes, if your interests or needs change throughout your career.
The second half of the course (the Stream), is squarely focused on growing grapes and other aspects of working in Viticulture. It gives you a very sound foundation for a business or employment in this industry.
The Core Units comprise fifteen lessons and are divided into the following sections:
- Introduction to Plants
- Plant Culture
- Soils and Nutrition
- Plant Identification and Use
- Pests, Diseases and Weeds
Core lessons are grouped into the following units.

What is a Grape?
Grapes belong to the Vitaceae family. Within this family, only the genus Vitis is of any great interest to viticulture, although four of the nine genera in this family yield grapes. The Vitis genus includes some 60 to 80 evergreen and deciduous shrubs, mainly of a climbing habit, supporting themselves by tendrils.
Almost all commonly cultivated grapevines belong to the species Vitis vinifera, although other species have some use in viticulture: for rootstocks, materials for hybridisation and, in some circumstances, for actual grape production. The commonly grown grape vine (Vitis vinifera – also known as the European Grape) originated from Asia Minor and has been carried with civilisation for thousands of years throughout history. Vitis vinifera was taken to Mexico by the Spaniards. English settlers took Old World grapes with them and planted them along the Atlantic seaboard.
These however failed due to the presence of the insect phylloxera, and fungus diseases like Black Rot, Downy Mildew and Powdery Mildew, as well as deleterious effect of low winter temperatures and hot humid summers.
Vitis vinifera requires a warm temperate climate, with minimum temperatures of -2°C while dormant,
-1°C at bud burst and -0.5°C when in full flower. The root system is deep, and as such can draw water from lower levels of the soil; hence the need for high rainfall or irrigation is only moderate. Effective irrigation methods in suitable climates can, however, improve quality and quantity of yields.
The vine does not tolerate wet soils in summer but will tolerate some wetness in winter.
When on a trellis it will tolerate wind reasonably well, but not strong gale force winds. Though sandy soils are preferred, grapes will tolerate most soils provided they are deep and well drained.
Some other grape species that are of significance to viticulture include:
- Vitis amurensis
- Vitis labrusca
- Vitis riparia
- Vitis rupestris
- Vitis berlandeieri
- Vitis aestivalis
- Vitis cinerea
- Vitis rotundifolia
The Genera Vitis and Muscadinia
Plants from both of these genera are called “grapes”. The world viticulture industry concentrates on growing cultivars of Vitis vinifera. Cultivars of other species from both genera are however grown for edible fruit in various parts of the world.
Vitis has forked tendrils, sheds its bark, has a diaphragm (continuous pith) at the nodes, and elongated clusters with berries that stick to the pedicels at maturity.
Muscadinia has tight bark that does not shed, simple tendrils that do not fork, nodes without a diaphragm, and small clusterlets with berries that detach as they mature.
Vitis vinifera also have intermittent tendrils, thin, smooth shiny leaves with 3, 5, or 7 lobes. The berry size varies.
Species used for grape production
Vitis vinifera cultivars produce over 90% of the world's grapes, whether as pure vinifera or hybridised. The most important grape species used in North America are:
- Vitis labrusca - Concord, Niagara
- Vitis aestivalis - Norton, Delaware
- Vitis vulpina - Elvira, Clinton
- Vitis rotundifolia - Scuppernong, Eden, Muscadine
- Vitis rupestris - Rupestris St. George
The Concord variety makes about 80% of the total American production. Many grape varieties have been crossbred between species and even other hybrids to produce improved characteristics of the fruit, growth habit or even disease resistance.
Root stocks that exhibit resistance to phylloxera have become invaluable in the industry. Some of the American species used as root stock that have resistance are Vitis riparia, Vitis berlandieri, Vitis rupestris, Vitis aestivalis, Vitis cordifolia, and Vitis monticola.
Rootstocks that exhibit resistance to nematodes are also important. These include from America: Vitis rotundifolia, Vitis champini, Vitis candicans, and Vitis long.
An International Industry
The wine industry is truly international, with different countries recognised for certain grape varieties and styles of wine, to others aiming for particular value areas of the consumer market. Factors such as location, climate, environment, and soils will determine what types of grape variety are most appropriate for the vineyard.
Studying the Certificate In Horticulture (Viticulture) will provide you with a solid introduction to the wine industry, developing your knowledge of different grape varieties, how to grow them, how to manage them, and what processes you need to follow for harvesting your crop. Allied to this will be the valuable horticultural knowledge that you have developed in the first part of this course. This place you in a better position when managing your crops, but also provides you with the knowledge to consider other crop options in the future should you need to.
Our Students Say
"[The course] gave me extra knowledge of the industry that I am currently working in. It covered all aspects of the industry. I liked the way you had to work through each lesson/category I received excellent feedback from my tutor. I enjoyed the viticulture course, it has given me extra knowledge that I will use."James McKelvey, Vineyard Manager, Viticulture course.
