California's 2024 grape harvest has commenced earlier than expected due to a variable weather pattern, with some regions experiencing a shorter growing season. Despite the challenges, including late spring weather and reduced yields, the quality of the grapes is reportedly high. California, the fourth largest wine-producing region in the world, accounts for approximately 80% of the U.S. wine. The majority of California's wine is produced in sustainably certified vineyards, with over 65% of the state's approximately 610,000 acres of vineyards holding a sustainability program certificate.
