Quick history, I don't bottle often. I did for my first year or so as par for the course when I got into brewing. I almost always keg, with the exception of the occasional demand for my seasonal brews. Never really had/have any issues. Like most, I boil said 5 oz corn sugar in 2 cups of water for a 5 gallon batch no matter the style, let cool, pour into a bottling bucket, rack from fermenter etc. Nothing special, especially considering I've done it quite a few times haha! I recently did a Chinook smash IPA, nothing exotic or fancy. Pulled a sample right before bottling and was great, no issues as anticipated. During transfer to the bottling bucket it got a little O2 in the beginning because the hose clamp was a little loose, but nothing crazy (oxidiation possible, but doubtful considering I used to siphon and always ended up pumping way too much O2 without issue.) Here's the crazy issue......after about 10 days in the bottle for conditioning, I threw one in the fridge this morning for assumed happy consumption this evening. Yikes! Being that it was a heavily hopped and dry hopped beer I've done before, of course my expectation at first sniff was hoptastic. It smelled like a seltzer water with sugar and to my ultimate chagrin, tasted like it. It was next to awful (sad face.) After considering breaking the glass in my hand with anger, I stepped back and asked, what the F$&K!? Any one that's been around for years experienced this? Carbonation was expected to be too much as I only ended up bottling 4 gal instead of 5. Got it. In my experience though, even that wouldn't cause the beer to be anything but over carbonated which is slightly was. No malt or hop taste at all, and this particular beer is extremely flavorful! Guess I'm just scratching my head on this!
