The operations at Teusner are focused on exceptional wines, by being very selective about the quality of grapes, grown to old, well maintained vineyards. The sources are predominantly family and close friends. Parcels that are recognized for their suitability to barrel age are held back, as individual components, for a year before assembling. Grenache and Mataro are picked off some stately old vineyards in Ebenezer. Shiraz hails from younger but mature vines at Williamstown. Components are treated to several days of cold soak, followed by ferments peaking at 28C. Upon completion, batches are filled to a selection of seasoned oak puncheons and hogsheads for a year's maturation.
