Sanctuary Peak Sauvignon Blanc 2017
Elgin’s climate is milder than the average Mediterranean climate. Snow occasionally covers the highest peaks. The “Black South-Easter” known for its gusting cold winds and rain showers is the result of strong summer south-easterly maritime winds blowing off the South Atlantic Ocean 12 kilometers away. This creates a cloud mantle across the Elgin valley, markedly lowering daytime temperatures. This cool climate ensures long, slow ripening of the grapes under ideal growing conditions, with the sugar, pH, acid and flavour compounds in balance to produce elegant and refined wines. Shannon Vineyards grapes ripen later than other Cape vineyards and are in perfect balance. Elgin is classified as Region II on the Winkler scale. Growing conditions on the north facing slopes are similar to Bordeaux and its south facing slopes similar to Burgundy.
The grapes are chilled to 3C. The bunches are sorted on a conveyor, destemmed and crushed. All transfers of grape must and juice in these early stages are attained using gravity. Selected parcels of the grapes undergo a period of skin contact, at 8C to encapture favourable skin avours. After a gentle pressing, the juice left to settle for a period of 72 hours at 2C. Fermentation in stainless steel tanks continues at 12oC until the wine is dry. The 11% blended Semillon is fermented on natural yeasts and matured for 3 months in 100% new French oak and bâtonnage (lees stirring) practised fortnightly.
The focus of this wine is based on a vineyard component arising from low yielding Table Mountain Sandstone soils. Using neutral yeasts, Shannon Sauvignon Blanc expresses very distinctive and concentrated primary fruit aromas of asparagus, citrus, and some capsicum in a minerally and inty style. The clay/shale soils however, provide the Sauvignon with avours on the riper side of the fruit spectrum and with more structure for a broader palate. The blending in of naturally fermented Semillon, matured on the lees, provides a fuller mouth feel and adds to the complexity of the wine. This wine was vini ed in a style that enhances the aging potential of Sauvignon Blanc.
