Please help me prove my douche bag brother-in-law wrong!!!? - whole pickle bag

So I was throwing some cucumbers, which expired in February this year. But my idiot brother-in practically called me stupid and said, "That's cucumbers. Brines are" over and over again as if I were willing to take an idiot to almost 10 months earlier. Please someone tell me how long unopened

No wonder why our whole family hates him ....
