Read about the same grape variety in two different countries.
In Italy, Ugni Blanc is called Trebbiano Toscano. Do not lump together multiple varieties under just the term Trebbiano; always use the full name including Toscano. Knowing these synonyms allows you to directly compare French and Italian materials from a common starting point.
Wine is made before distillation.
Cognac is a spirit made by distilling wine from white grapes. The BNIC lists white grapes with low sugar and high acidity as the raw materials. Separating the alcoholic strength of the finished spirit from that of the pre-distillation wine clarifies why acidity and sugar levels in the raw materials are important.
Read according to the intended usage.
Simply knowing 'Ugni Blanc is used' does not tell you whether the bottle contains white wine or Cognac. The grape variety is the raw material, distillation is the subsequent process. First, identify what kind of product it is: if it's white wine, follow fermentation and aging; if it's Cognac, go through to distillation and aging.

What is the Italian name for Ugni Blanc?
The corresponding variety is Trebbiano Toscano. Treating all names containing 'Trebbiano' as the same variety can result in confusing sources. When comparing across countries, confirm individual variety names instead of shortened common names.
What qualities are required of the white varieties used to make Cognac?
The BNIC explains that white varieties with low sugar and high acidity are used as base material for distillation. This concerns requirements for the raw material before distillation. Do not apply the final alcohol content of Cognac products as if it were the characteristic of the grapes or the wine immediately after fermentation.
If the grape variety is Ugni Blanc, is it always Cognac?
The grape variety name indicates the raw material, which is different information from the product name Cognac. Whether or not the white wine is distilled after making it divides the processes. In comparison, first note the grape variety in common, then check the order of fermentation, distillation, and maturation.
