Knappstein has been the most conspicuous name in the development of Clare Valley wine since 1895. Originally established by Tim Knappstein as Enterprise Wines, the low yielding Enterprise Vineyard yields some of the region's finest Cabernet Sauvignon, exhibiting bold concentration of flavour, distinctive mint eucalypt flavours, fine, velvety tannins and striking acidity, as derived from the iron rich soils and limestone geology. Replanted in 1969, the calibre and typicity of Enterprise Vineyard has shone consistently throughout the years.

Mostly Cabernet Sauvignon with smaller components Merlot and Cabernet Franc, sourced from the estate's Yertabulti, Enterprise and Ackland vineyards. A couple of carefully selected growers from a little further north in the Clare Valley also contribute grapes. The diverse range of vineyards enhances the rich textures. The wine was made with minimal intervention to preserve fruit purity. Vinified in a combination of static potter and open fermenters for over a fortnight, with gentle extraction of flavours and texture through pumping over and hand plunging four times daily. The skins are then pressed and the wine allowed to settle before transfer to a selection of fine oak barrels for ageing.
