500ml to 440ml?
Edit: the 440 on the right, is the last of a can that I bought in a four pack. The 500 on the left, is one of three I bought as singles.
Packaged Guinness comes in 440 milliliters. Single cans of Guinness come in 500 mL.
Apparently, that’s how Guinness does it here in Canada.
And apparently, I lazily avoided any attempt to research or apply any level of critical thinking before posting.
While I agree with the general sentiment, these are both standard sizes for Guinness and the 440ml 4 packs and 8 packs have been around for well over 20 years. Here in Canada, the 440ml are available in the multi packs while the 500ml are sold as individual cans. I’ve seen the same in the states. I think OP just saw the smaller volume can next to the slightly bigger one and jumped on the shrinkflation hate train without checking.
