“So actually, an older apple in a grocery store can be eight months to a year and a half old.”

The claim, plainly

Older apples sold in grocery stores can be eight months to a year and a half old.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

Published data from agricultural extension services (Washington State University, Cornell University), the USDA Agricultural Research Service, and industry associations (USApple) corroborate the assertion that older commercially sold apples can be 8 to 18 months old. Controlled Atmosphere (CA) storage regularly maintains 60% of the harvest for distribution across 8 to 12 months post-harvest. Furthermore, the use of Ultra-Low Oxygen (ULO) and 1-methylcyclopropene (1-MCP) ethylene inhibitors permits extended holding of firm apple cultivars for up to 14 to 18 months (a year and a half), validating the upper bound of the claimed range.

USApple data indicates 60% of the U.S. apple crop is stored in CA facilities and marketed across the 8 to 12 months following harvest.
USDA Agricultural Research Service notes that 1-MCP extends commercial storage condition by an additional 3 to 6 months beyond standard 10–12 month CA storage.
Postharvest engineering documentation confirms Ultra-Low Oxygen (ULO) and Dynamic Controlled Atmosphere (DCA) storage systems achieve viable holding periods of up to 12 to 18 months for firm apple cultivars.
