Berry Shatter in Grenache
Grenache have shed flowers which were not fertilised to form berries. This ‘shatter’ of bunches has been seen across all vineyard areas. This 'shatter' can look like the vines have been burned. (c) James Hook
Shatter can be due to a number of factors including wind, high temperatures, water stress & nutrition. In many vineyards it may be a combination of several of these factors.
