The Koltz Shiraz is the first of the estate grown wines and comes from a small block of shiraz at Blewitt Springs. It is produced in small volumes and is open fermented and basket pressed. Portions of this wine undergo extended maceration for up to 50 days, depending on the season and grape maturity.
Once pressed it is aged in French oak barrels for 16 to 20 months. Approximately 30% of the barrels are new and the others one and two years old.
Blewitt Springs is generally 2 to 4 weeks later than most of McLaren Vale and this combined with the sandy soils over ironstone produce distinctive wines.
Tatsing notes: Typically, these Koltz Shiraz show aromas of blueberries and earth and are elegant with velvety tannins and good length. Extended maceration contributes to the complexity of Koltz Shiraz and the aim with this wine is to produce a wine which reflects both the vineyard site and the philosophy.
