I don’t completely agree with you but I also don’t disagree. A strong, fruity IPA is my favorite type of beer. The “best” NEIPA’s are very unique and delicious, and expensive to buy and make. On the other hand I appreciate and love the taste, crispness, and refreshment of a true European beer. My wife and I went to Oktoberfest this year and I absolutely loved the German Festbier. It’s hard to compare the different styles and I can’t be biased.
I’m guessing that the beers were dryhopped in a keg, bottled off the keg since I didn’t see sediment in the bottles, generally kept cold, but for a few days stored warm allowing some fermentation to occur allowing the diacetyl to be created but not enough to clean up the diacetyl.
