That is ridiculous. 60 minute doesn't taste at all offensive, and is pretty tame as far as IPAs go. The only way I can see somebody hating it is if they just plain hate hops, and therefore any style that is hop-focused. It's a bit too floral for it to be one of my favorites, and I do greatly prefer 90 minute, but it's hard to imagine that anybody who likes American craft beer can hate the 60 minute so much.
So I have to agree that something happened to the beer. Perhaps it was oxidized or lightstruck, but in any case it was almost definitely mishandled - likely the distributor or retailer, but possibly also the consumer and, least likely of all in this case, the brewery itself.
And this highlights how important it is to not just write off a beer entirely just because you had one bad bottle or glass. And also justifies the length some breweries go to in order to ensure their beer is handled and served to their standards, because many customers can easily be lost due to a single distributor or retailer not caring about preserving the integrity of the product and the quality that ends up reaching the consumer. Which of course causes many to conclude that the beer is just bad overall and making sure to avoid it in the future because they (think they) don't like it.
