Stroll off the beaten track of a mountainside or valley vineyard in the Western Cape winelands of South Africa and step into wild, straggly vegetation of every shape and size. Brushing through these bushes releases many scents: heady dried herbs, wildflowers, pungent spice and more.\r\n\r\nThis is fynbos, the Afrikaans word meaning fine-leaved plants. Fynbos is composed of around 8,500 species from several key families\u2014Restionaceae, Proteaceae, Ericaceae, Rutaceae and Iridaceae\u2014many endemic to and part of the Cape Floristic Region, or the Cape Floral Kingdom.\r\n\r\nUNESCO added the Cape Floral Region to its World Heritage List in 2004, citing it as one of the world\u2019s greatest centers of terrestrial biodiversity.\r\n\r\n\r\n\r\nFynbos vegetation thrives in poor soils under tough climatic conditions and the Cape\u2019s hot, dry summers. Many types of plants from the fynbos biome can be found in close proximity to vineyards in the Cape Winelands, and can potentially influence a wine\u2019s aromas or flavors due to the spread organic materials like plant oils or pollen.\r\n\r\nThe earthy melange of herbal and floral fragrances that fynbos offers can brings to mind Syrah, Grenache and Mourv\u00e8dre, alone or blended. While these varieties may be often associated with the Rh\u00f4ne Valley, they are also widely grown in the Cape.\r\n\r\nThe South African red wines of today promote an expressive aromatic range of fynbos influence. The aromas can be quite intense. After rain, the scents are fresher and purer, with the expression of petrichor\u2014an earthy smell produced after rain falls on dry soil\u2014elevating aromatic complexity.\r\n\r\n\r\n\r\nThe composite nature of the fynbos plants generally makes it difficult to isolate any one aroma. Buchu, one of many species in the genus Agathosma, meaning \u201cgood fragrance,\u201d is an exception. It is highly aromatic, resembling a peppery note often found in Syrah (the peppery taste in Syrah comes from rotundone, a sesquiterpene).\r\n\r\nThe perception of \u201csavoriness\u201d in a wine, led by tones of herbs and spices, may also be augmented by fynbos characteristics.\r\n\r\nRichard Kershaw, MW, produces namesake wines that include Syrah grown in Elgin, a cool-climate region. He believes there are several climatic factors that create the elegant, medium-weight expression the area is known for.\r\n\r\n\u201cThe end result is a translucent wine of medium-dark color, the accent on red fruit with black cherries but also vibrant spice, more savory than sweet,\u201d says Kershaw.\r\n\r\nIn warmer areas like the Swartland, spicy, peppery notes can still show intensity, but are often deeper and partnered with more forward fruit characteristics.\r\n\r\nFloral scents can also be apparent, especially in Rh\u00f4ne-style red blends, redolent of wild rosemary or lavender.\r\n\r\n\r\n\r\nOverall, given the breadth of different species of fynbos, it\u2019s easy to see why the many varied scents it encompasses could make for a confusing wine tasting note.\r\n\r\nBut even if fynbos can\u2019t be defined as expressly reminiscent of a particular or familiar smell, its warm-hearted wildness should remind you of the attractively generous wines of South Africa\u2019s Cape Winelands, and the natural beauty that surrounds it.
