We only had time for one winery that day so we chose Groot Constantia, the oldest winery in all of South Africa, dating back to 1685. It has cellar tours, wine tastings, two on-site restaurants and a historical museum as well. Groot Constantia is known for the high-quality red wines it produces, including Shiraz, Merlot and blended red Gouverneurs Reserve. Best part is it's right in Cape Town. Just take the red bus tour and it drops you off right at the door. Adjacent to the winery route is the famous Kirstenbosch National Botanical Gardens. What a lovely day of exploring wineries and gardens. Cheers!
