Can someone please setting a argument between me and my best friend

So a little back ground, my best friend has worked as a brewer of beer and hard seltzer for about 5 years. He is a moderate drinker and often goes to bars/breweries to drink. I am the occasional drinker, have no knowledge when it comes to brewing beer.

So it is currently Dec 2025 and we live in the south. Around April 2025, he and I went to a brewery and he bought a couple of 4 packs of hard seltzer and at the end of the night he left one of those 4 packs in the hatch of my car. Well I found it last week, was going to dispose of it but according to him, it is still good and he wants to drink it. So I want to state this upfront, for the last 8 month that hard seltzer has been unrefrigerated, in a HOT car ( the summers here can get to 100 or above), not covered so exposed to the sunlight, and probably shaken up some because I drive a lot. Is it still good?

Also sidebar this is on my best friend, there is nothing on earth that will have me drinking that. He really wants to drinking it because he claims it is still good.
