Final answer:
True, the base wines for Armagnac typically have less acid and more alcohol than those used for Cognac due to the warmer climate in the Armagnac region resulting in higher sugar levels and lower acidity in the grapes.
Step-by-step explanation:
The statement that the base wines for Armagnac have less acid and more alcohol than base wines used for Cognac due to the warmer climate of the Armagnac region is true. The warmer climate of the Armagnac region generally results in grapes that achieve higher sugar levels before harvest, which then translates into higher potential alcohol content in the resulting base wine. However, a warmer climate can also lead to less acidity in the grapes, as cooler growing conditions are typically associated with higher levels of acidity in wine grapes.
