Bitter beer face

Today I found out the hard way that Coke has a “best before” date. I noticed when I was pouring it in the cup, that it seemed like it wasn’t fizzing as much as usual. But the real distinction became apparent when I tasted it. Yuuuuuccckkk. I looked at the bottle, and it had expired on March 31. I thought that soda had a shelf life of at least 50 years. Nope. I’m going to have to dig through the stash and purge all of the old stuff.
