Koltz is a small winery located in the cooler Blewitt Springs sub-region of McLaren Vale. The winery is on our own vineyard and we make our wine using very traditional methods. Hand picking, small open fermenters, hand plunging, extended maceration and basket pressing are utilized to produce hand crafted wines.

Winemaker Mark Day has worked in McLaren Vale for nearly 25 years and has also spent 9 vintages working in Europe, particularly in Italy. This experience has naturally influenced our wine making and we try and produce wines which are Australian in nature  with Italian influences.

In particular Koltz Wines have been influenced by the great amarones of Valpolicella. These wines are made by drying the grape for several months before crushing to increase complexity and to produce wines which are layered and packed with flavour. We use shiraz from our Blewitt Springs vineyard to make wines which reflect this style.

Our top wines are estate wines, grown and made on our property at Blewitt Springs. They are made in very small volumes with a hands on approach and a passion for what we are trying to achieve.

To further express our love of italian varietals we have planted 2 acres of sangiovese and sagrantino at Balhannah in the Adelaide Hills to produce our cool climate wines under the Eccolo label.
