Climate

Tulbagh is situated 120km north east of Cape Town and 90 km east of the Atlantic coast in a Mediterranean climate area. Cold winters with rain and snow, and warm dry summers with plenty of wind. The valley is surrounded by mountains, resulting in cool nights.

The water retention properties of shale are very low. This naturally restricts vine growth resulting in small concentrated berries and bunches. Another excellent property of shale is that the wine produced has a low ph which allows for long ageing of our wines. Our low potential shale soils produce on average between 6 and 7 tons per hectare.

Cabernet Franc, Cabernet Sauvignon, Merlot, Pinotage and Shiraz.

In 2010, ten years after our first harvest, we removed all Cabernet Franc, Cabernet Sauvignon and Merlot so as to concentrate on the cultivars best suited to our farm : Chenin Blanc, Pinotage and Shiraz. A very good decision.

Soil

The entire farm consists of vertical shale soils, also known as schist. This soil type has typically 300mm of topsoil and then deep vertical shale.

Vineyards

Our first plantings were in 1997. After extensive soil tests, discussions and planning, we decides to plant many cultivars to see which siuted our farm best. White wines included Chenin Blanc, Chardonnay, Sauvignon Blanc and Viognier. Red vines planted were :

Plantings

Each block is around one hectare. Rootstocks used are Righter 99 - drought resistent with  low growth. Row direction is mostly east to west thus following the sun. Row width is 2.5 mt, and vine spacing is from 0.8 to 1.0 mt. Plant density is from 3600 to 4400 vines per hectare. We use two trellis systems - open Perold trellis (producing very fruity grapes) and extended bush vine (producing fully concentrated grapes).

The start of the growing season begins in spring around the first week of september at budburst. This is when we at Rijk's start to "grow wine" and the new shoots begin their journey towards the sun. The management of the canopy is the most important aspect in our endeavour to produce  quality grapes. Farm manager Martin Human and his 15 permanent workers spend every day in the vineyards - thinning, removing unwanted shoots, removing leaves in the bunch zone, opening up the canopy to light and sun. This also allows for healthy, disease free vines and creates a canopy microclimate perfect for the production of low yielding grapes.




A basic summary of the growing season programme we follow to produce optimum quality grapes :







Mid november

Fruit set and then Pea size

This is when the bunches begin to form.

Remove unwanted leaves in bunch zone. If leaves are removed to late this will result in sunburn to bunches. Little or no irrigation to reduce growth and berry size.

Canopy management and how we "grow wine"

Our permanent people

One week before harvest

Quality control of bunches - remove any bunches that have not ripened evenly.

Check sugar, acid and ph level, taste berry flavours, check pip colour. Winemaker Pierre will then decide when to harvest

1st week september - Budburst

When the buds start swelling and the first shoots appear - normal irrigation.

3rd week september 10cm shoot growth

Spacing between shoots thinned to 150 mm apart. Thinning to 2 shoots per spur. This is critical as it sets the spacing and growth of shoots for the whole growing season. Full irrigation applied

3rd week october - Flowering

Vines must be strong and healthy with sufficient soil moisture

End December - Veraison

Colour starts showing in the berries. Shoots with less than 12 leaves - remove bunches as they will not ripen well. Bunch counts are then done on each block to determine tonnage expected. If yield will be to high, bunches are removed. Target is 5 tons per hectare.

Night harvest - Last week january till mid march

The moment we have waited for. The time, effort and attention to detail of each block will now pay off. All harvesting is done at night to get bunches to the cellar as cool as possible to retain freshness and flavours.

Post Harvest

After working so hard to produce quality bunches, we reward the vines with a good irrigation and small amount of fertilizer.


Pruning - mid july

Prune back to 2 buds per shoot - this is critical as how you prune will determine the amount of shoots and therefore the quality and yield for the next vintage.
