Question 1
A guest asks why Terra Alta doesn't simply replant its old Garnacha Blanca vineyards with modern rootstocks to improve yield consistency. What is the tradeoff worth explaining?
A
The ancient vines' deep roots access subsoil moisture with a precision modern rootstock plantings cannot match, a natural drought management advantage that would be lost
B
Modern rootstocks are banned outright under Terra Alta's DO regulations
C
Old vines produce higher yields than young rootstock plantings, so replanting would reduce output
D
There is no meaningful difference; replanting would have no effect on drought tolerance
