Mandela effect question...am I hallucinating a drop in alcohol percentage for Coopers Sparkling that has since been reversed?

When I first started drinking in 2003, I remember it being noticeably higher percentage than most beers. Then at some point (2010s?) It dropped to be in line with other mainstream beers, in the 4s

Had a bottle tonight at my friend's house and it was 5.8%. Another friend was certain that it's always been similarly strong.

Am I losing the plot, or was it a lot lower for a good while?

Edit: Huh, there ya go. I was sure they'd dropped it down to be the same as green for a while, but I've got that wrong. Thanks for all the answers everyone šŸ™
