Why Grow Grapes?
Grapes can be grown for the following uses:
These are grapes which are sold and used fresh. These varieties must look and taste good, and resist bruising or other damage when handled.
Preferred qualities are:
- large berries
- even-sized berries
- strong skin
- strong stems
- good shelf life
- seedless (in some markets)
- bunches which are neither loose nor dense (berries should not be too sparse, nor too tightly together)
Some varieties used as table grapes include Cardinal, Black Muscat, White Muscat, Waltham Cross, Purple Cornichon, Flame Seedless and Marroo Seedless.
These grapes are crushed and fermented to produce wine. Red or rosé wines are produced by fermenting after crushing while the grape skins are still present. For white wines, the skins are removed before fermentation. Some varieties have skins which add more colour to the wine, others less.
Grapes with high acid content and low sugar will produce dry wines. Grapes with high sugar and lower acid produce sweeter wines. The amount of acid and sugar in a grape depends upon the variety of grape, plant culture, and the stage at which it is picked.
Mechanically harvested wine grapes should have berries which detach easily from the stems and have thick skins which don't damage readily. Thin-skinned grapes must be harvested more carefully.
Varieties commonly used for high quality red wine include Cabernet Sauvignon, Cabernet Franc, Malbec, Merlot, Shiraz and Pinot Noir.
Pinot Noir is often used for rosé.
Varieties often used for quality white wine include Chardonnay, Semillon, Sauvignon Blanc and Gewurztraminer.
Virtually any grapes can be dried, but the varieties used commercially are generally seedless types which ripen fast and at a dry time of year. They must not get moist and split near to harvest. The texture should be soft, and the fruit shouldn't stick together too much in storage. Sultanas (a white seedless variety) are particularly valuable, producing large dried fruits. Raisins may be produced from a range of different varieties, often smaller fruits, including Thomson Seedless, Muscat of Alexandria and Black Corinth.
Unfermented grape juice has gained increased popularity in recent times. Processes (eg. pasteurisation) used to preserve the juice can have a detrimental effect on the flavour with some varieties of grape, while others are not dramatically altered. Several varieties may be blended to produce juice.
Seedless grapes are sometimes canned, either alone or with other fruit as fruit salad. Thompson Seedless is commonly used for this purpose in the USA.
The viticulture industry is diverse and an interesting profession to follow if you have a passion for grape growing and the wine industry in general. There are opportunities for people with sound knowledge and skills, not just for work in the industry (which is a great starting point) but also for those who would like to set up their own vineyard. This course will give you a great grounding - it also offers you the opportunity to tap into the skills and knowledge of your tutor if you already have a vineyard or would like to set one up. There is still room for niche growers and winemakers! So if you are ready to learn more - enrol and start turning your passion and dreams into reality.
