D1 is the unit everything else in the Diploma stands on. Every D3 answer about why a Barossa Shiraz tastes the way it does is really a D1 answer about climate, canopy, and extraction wearing a regional costume.
These questions sit at Diploma depth: not what malolactic conversion is, but why a producer would block it in an aromatic white and encourage it in a barrel-fermented Chardonnay. Explanations on every answer.
