GI Exercise: What does a larger regional name indicate? — Points for comparison
Read geography, grape resources, and production processes separately.

Composition ratio in each region
Assessment
Single designation applies when each component accounts for at least 85%.

FIELD NOTE 01
Use Barossa as an example
Barossa is a zone, and both Barossa Valley and Eden Valley are regions within it. When only 'Barossa' is stated, you can't determine which region or what proportions were used. Distinguish between what can be known from the label and what requires additional documentation.
FIELD NOTE 02
A narrow name is not everything.
There are wines that represent a specific region in detail, and wines that create a style from ingredients sourced from multiple regions. The extent of a GI's area by itself does not equate to a quality ranking. To understand blends that cross regional lines, you need to read the actual blend composition and labeling rules.
FIELD NOTE 03
Evaluate a hypothetical blend
If a wine is 90% Shiraz, 95% vintage year on the label, and 80% from Eden Valley, then by the basic 85% single-item rule, the variety and vintage year conditions are met, but the single-origin Eden requirement is not. Before speculating about other geographical indications, check the source of the remaining 20% and the multiple indication rules that apply.
A single-varietal GI indication for Eden Valley does not generally reach 85%. Judge variety, vintage, and region individually.
PAUSE & REFLECT
Check your understanding.
If a wine is 90% Shiraz, 95% the labeled vintage, and 80% from Eden Valley, can all three be shown on the label?

A single-varietal GI indication for Eden Valley does not generally reach 85%. Judge variety, vintage, and region individually.
