Let’s get started!

Introduction to Grape Farming in Kenya

The history of grape cultivation in Kenya dates back to the early 20th century when European settlers introduced the crop. 

In the past few decades, people have been growing grapes on a large scale. Local and export markets are driving this increase.

Grapes are a high crop value – they boost farmer’s income. 

Its high demand in wine tourism and local wine production presents an opportunity for Kenyan farmers to tap into new markets.

Global demand for grapes and grape-related products has been on the rise. 

Wine consumption is increasing globally. There’s also a growing market for table grapes and raisins.

Parts of the Rift Valley (such as Naivasha and Nakuru), some areas in Eastern Kenya (like Makueni), and pockets in Central Kenya are ideal for grape farming in Kenya.

These regions provide a warm, dry climate in which grapes thrive.

Varieties of Grapes Grown in Kenya

There are several varieties of grapes. So make sure to choose the right variety.

Let’s explore the different varieties available.

Wine grapes

• Cabernet Sauvignon: This red wine grape variety has adapted well to Kenyan conditions. It produces full-bodied wines that have rich flavors of blackcurrant and cedar.
• Chardonnay: A versatile white wine grape that has shown good results in cooler Kenyan highlands. It produces wines that have flavors ranging from crisp apple to tropical fruit.

These wine grape varieties adapt well to Kenya’s climate and soil conditions, especially in higher altitude areas with cooler nights.

Table grapes

• Thompson seedless: This popular green seedless variety has a sweet flavor and crisp texture.
• Red globe: A large, seeded red grape with a mild flavor. Its impressive size and appearance make it popular in local and export markets.

Table grape varieties are chosen based on sweetness, whether they’re seedless or seeded, and market tastes.

Raisin grapes

• Sultana: It is also known as Thompson seedless. This variety is good for raisin production because of its high sugar content and lack of seeds.

When buying varieties, consider your local climate, soil conditions, and target market likes. 

It’s often a good strategy to start with a mix of varieties to spread your risk and meet different market requirements.

Ecological Requirements for Grape Farming

Let’s explore the ecological requirements for grape farming.

Climate

Grapes grow well in warm, and dry climates. The ideal temperature range is between 15°C and 35°C. 

They are tolerant to hot and dry conditions. However, they are sensitive to frost.  Frost damages young shoots and flowers. 

Regions in Kenya with distinct dry seasons are often ideal for grape cultivation.

Soil

Grapes grow well in well-drained loamy or sandy soils. The ideal pH range is between 5.5 and 7.0 – slightly acidic to neutral. 

They can tolerate a range of soil types.  However, they grow well in soils with good drainage and moderate fertility.

Rainfall

Grapes need about 500-700mm of rainfall annually. However, they need a dry period before harvest – to concentrate sugars in the fruit. 

Supplementary irrigation is necessary in areas with less rainfall or poor distribution, especially during fruit development.

Altitude

Grapes in Kenya can be grown at altitudes ranging from 500 to 1500 meters above sea level. 

Higher altitudes can provide the cooler nights that some wine grape varieties like to develop complex flavors.

Sunlight

Grapes need full sunlight for proper growth and fruit development. Adequate sunlight is important for photosynthesis. 

Sunlight influences sugar content and flavor development in the grapes.

Propagation and Planting

Grapes can be propagated through several methods. However, vegetative propagation is the most common for commercial production.

Let’s explore all the methods.

Propagation methods

Cuttings

This is the most common method. Hardwood cuttings are taken from dormant vines in winter, planted in a nursery, and allowed to root before transplanting them to the field.

Grafting

It is often used to combine desirable fruiting varieties with disease-resistant rootstocks. This method is used in areas prone to soil-borne diseases.

Seed propagation

It is rarely used commercially because of its genetic variability and the long time it takes for seed-propagated vines to bear fruit.

Land preparation

• Clear the land of weeds and debris
• Conduct soil tests and amend the soil as necessary
• Prepare rows for planting, typically 2.5-3m apart

The best time to plant grapevines in Kenya is typically at the beginning of the rainy season (March-April or October-November). 

You take advantage of natural rainfall for establishment.

Planting Techniques

• Dig holes about 40cm deep and wide
• Place the young vine in the hole at the same depth it was growing in the nursery
• Fill the hole with soil, firming gently around the roots
• Water thoroughly after planting

Young vines require careful management in the nursery – proper watering, protection from pests, and gradual exposure to sunlight (hardening off) before transplanting to the field.

Grape Vineyard Management

Let’s explore effective vineyard management strategies.

Watering and irrigation

Although established grapevines are somewhat drought-tolerant, they need consistent moisture during fruit development. 

Drip irrigation is ideal – it provides water directly to the root zone. This reduces water waste and the risk of fungal diseases.

Fertilization

Grapes benefit from regular moderate fertilization. However, over-fertilization can lead to excessive vegetative growth instead of fruit production. 

A balanced NPK fertilizer can be applied annually. Nevertheless, additional nitrogen can be provided during the growing.

Pruning

Annual pruning is important in grape production. It helps maintain vine shape, controls growth, improves air circulation, and enhances fruit quality. 

Different pruning techniques are used for wine grapes – cane pruning, spur pruning, and table grapes.

Training systems

Grapevines need support to grow properly. Common training systems.

• T-trellis: Suitable for table grapes. It ensures good sunlight exposure and ease of harvesting
• Vertical shoot positioning (VSP): Often used for wine grapes. It promotes full-leaf and fruit exposure

Weed control

Keep the area around grapevines weed-free especially in the first few years of growth. 

Mulching is an effective way to suppress weeds. It also conserves moisture and adds organic matter to the soil.

Pest and disease management

The common pests are grape phylloxera and spider mites and major diseases are powdery mildew and downy mildew. 

Implement an Integrated Pest Management (IPM) approach – combine cultural, biological, and chemical control methods to fight pests.

Flowering and Fruit Development

Proper flowering and fruit development are important. They ensure a good grape harvest.

Let’s explore everything involved in flowering and fruit development.

Flowering period

Grapevines in Kenya typically flower about 2-3 months after bud break. The timing varies depending on the variety and local climate conditions.

Pollination

Grapevines are self-pollinating. The wind plays an important role in pollen distribution. Although bees and other insects visit grape flowers, they’re not essential for pollination.

Fruit thinning

For table grapes, fruit thinning is often necessary. It improves the size and quality of the remaining grapes. 

This involves removing some grape clusters or parts of clusters shortly after the fruit set.

Fruit maturity and ripening

Factors influencing fruit ripening are temperature, water availability, and sunlight exposure. 

Signs of mature grapes

• Color change (variety dependent)
• Softening of the berry
• Increase in sugar content (measurable with a refractometer)

Harvesting Grapes

Let’s explore what is involved in harvesting.

Harvest maturity

The timing of harvest depends on the grape variety and its intended use.

• Wine grapes: They are harvested based on sugar content, acidity, and flavor profile
• Table grapes: They are harvested when fully colored and sweet, but still firm
• Raisin grapes: Left on the vine longer to increase sugar content before harvesting

Harvesting techniques

Grapes are typically harvested by hand to avoid damage. Farmers use clean, sharp scissors or secateurs to cut the grape clusters from the vine.

Post-harvest handling.

1. Handle grapes gently to avoid bruising
2. Sort grapes based on quality, removing any damaged or diseased fruits
3. For table grapes, cool quickly to remove field heat and maintain freshness

Packaging and transport

Pack grapes in shallow, ventilated containers to prevent crushing. Use modified atmosphere packaging for long-distance transport to extend shelf life.

Processing Grapes

Processing grapes can add value to your crop.

Let’s explore the possibilities.

Wine production

The winemaking process involves several steps.

1. Crushing and destemming the grapes
2. Fermentation (with skin contact for red wines, without for most white wines)
3. Pressing to separate juice from skins
4. Aging in tanks or barrels
5. Bottling

Juice production

To produce grape juice

1. Crush and press the grapes
2. Heat the juice to pasteurize it
3. Filter and bottle the juice

Raisin production

1. Harvest grapes at peak sugar content
2. Dry grapes in the sun or dehydrators
3. Process and package the dried grapes

Value Addition

Other grape products like grape seed oil or vinegar can provide additional income streams.
