Can Grapeseed oil be considered edible after it has passed the expiry date?
It has a decent glass bottle, and airtight cap? It wasn't in bright light for two years, and doesn't look like it has polymerized deposits or smell rancid? As a polyunsaturated oil, grape seed is susceptible to oxidation/polymerization/rancidity. If it hasn't done any of these things, by the evidence of your senses, it should still be OK.
