The most fragile style in craft beer. Here's the freshness window for NEIPA / Hazy IPA, what makes it age the way it does, and where to find the best examples.
Reference specifications from the BJCP Beer Style Guidelines (2021 Edition), style 21C Hazy IPA:

NEIPAs derive their character from late-addition and dry-hopped aroma compounds — myrcene, linalool, geraniol, and various polyfunctional thiols. These molecules are extremely volatile and oxidize within weeks of packaging. Once oxygen breaches the can or oxidation reactions complete inside, you lose the bright tropical and citrus notes that define the style. The hazy mouthfeel also softens as the protein-polyphenol matrix that creates it slowly settles.
Keep cold from packaging to glass. Storage above 50°F dramatically accelerates degradation. Avoid any light exposure (the cans help). If you can't drink immediately, keep refrigerated and consume within 30 days. Never warm-cycle a NEIPA — heat-then-cold accelerates staling.
As soon as physically possible after canning. Most NEIPA-focused breweries (Tree House, Trillium, Other Half, Monkish) release cans within days of packaging and recommend drinking within 30 days. After 60 days, expect significant character loss.
These breweries either specialize in NEIPA or produce notable examples:
