A variety of white wine grape used for making champagne and other wines.
A wine made from the Chardonnay grape. Chardonnay (pronounced: [ʃaʁ.dɔ.nɛ]) is a green-skinned grape variety used to make white wine. It originated in the Burgundy wine region of eastern France, but is now grown wherever wine is produced, from England to New Zealand. For new and developing wine regions, growing Chardonnay is seen as a “rite of passage” and an easy entry into the international wine market.[1]
