The 2023 growing season in South Africa was a tale of two vintages. For producers in the Swartland and northern wine-producing regions, and for those with early-ripening varieties, 2023 offered fantastic ripening conditions – it was relatively cool during the year, without heat spikes. But as I drove through the Western Cape last month during my weeklong stay in South Africa, it was hard to ignore the giant scars on the mountains towering over the country's winegrowing valleys.
These were a reminder of the catastrophic floods and landslides that came at the end of months of heavy rainfall that started in February that year. The continuous rains were a disaster for varieties like cabernet sauvignon in later-ripening areas.
“It was the first year as a winemaker that I saw botrytis in cabernet [sauvignon] in South Africa,” said Boekenhoutskloof winemaker Gottfried Mocke, who described 2023 as “two vintages in two months.”
A later-ripening portion of cabernet grapes at Boekenhoutskloof was picked after 300 millimeters of rain fell in a single weekend. To avoid dilution in the final wine, they took off 30 percent of juice from the tanks before fermentation - a method known as saignee, which is used to concentrate flavors, color or tannin in the final red wine, or to draw off light-colored juice from red grapes to make rosé. Most 2023 cabernet sauvignon-led reds haven’t been released yet, so we’ll have to wait for next year’s tastings to find out if the quality is there, likely at lower quantities.
