Barossa workshop demonstrates old-vine Grenache renewal and shoot thinning

A Barossa Valley workshop demonstrated how old Grenache vines are reworked, WineTitles reports. The Barossa Viticulture Technical Group event took participants through three vineyard blocks with Tom Bartholomaeus and Torbreck Vintners’ Nigel Blieschke. At a block reworked in 2020, shoot thinning had been used to control vine density, prevent clumping and improve airflow.
