We get this question and concern quite often and we totally understand.
However, we have not changed the recipe of Oberon nor do we have plans to do so.
Sensory memory can be a little tricky. Often, and especially with Oberon, what you were doing the last time you enjoyed that beer will influence your taste. For a lot of people, enjoying Oberon is as much about the experience as it is about the beer (sun, warm temperatures, backyard BBQs, etc.).
Anything you were eating or drinking either before or during can also influence your taste. Or if you have or have not been drinking other hoppy beers recently, that too can also influence your taste buds as your palate can become sensitive to hops.
It’s kind of like hot sauce, the more you use it, the less intense it can become. Or vice versa. And it is entirely possible your palate has changed over time – especially with so many other craft beer options out there.
