Despite the official opinion of the Beer Search Party blog of anti-hard seltzer, I have tasted various options including the White Claw (which should be avoided) and even recently had a nice one from Wild Basin aka Oskar Blues with a melon/herb flavor profile.
If you had told me that seltzer would still be a thing in 2021 with practically every brewery having one on offer, I would have choked a bit on my predictions. I do think (now) that they are probably going to hang around for a few more years before completely fizzling out but it will be only because the market got overheated vs the customer base.
The final nail in the seltzer coffin will come from a new drink of the summer of ‘21 or ‘22 whichever will steal thunder and the bubbles will fade.
