This study evaluated how storage duration and packaging affect the phenolic composition and sensory quality of Corbella EVOO. Oils were analyzed at production and after 6 and 12 months of storage in two types of packaging: bag-in-box; stainless steel containers with a nitrogen headspace. UPLC-MS/MS profiling quantified 23 phenolic compounds, predominantly secoiridoids such as oleuropein and ligstroside aglycones. Oleuropein aglycone increased over time, whereas ligstroside aglycone peaked mid-storage before declining, likely converting to oleocanthal. Lignans and flavonoids degraded during storage, although luteolin increased, potentially due to glucoside hydrolysis. Bag-in-box packaging better preserved phenolic content than stainless steel. A sensory analysis corroborated the chemical findings, with oils stored in stainless steel showing greater reductions in pungency and astringency. A Pearson correlation linked bitterness with oleuropein aglycone (r = 0.44) and oleacein (r = 0.66), pungency with oleocanthal (r = 0.81), and astringency with oleacein (r = 0.86) and oleocanthal (r = 0.71). These findings highlight the importance of packaging in preserving the phenolic composition responsible for the sensory qualities of EVOO over time.
