My first duty station was in England in the late 90's. Shortly after I arrived there, some of the guys took me to a Belgian themed pub in Cambridge called the Hogshead and introduced me many English and Belgian beers one of which was Hoegaarden. I swear the stuff was magical back then and they must have changed the recipe. It had its own glorious tower, separate from all the others. I even ended up working at that pub part part time for a few months. When I started, I had to watch a training video specifically about how to pour a perfect pint of Hoegaarden.
Now, it doesn't taste anything like I remember it. I rarely, if ever drink that or any Belgian Wit. Still, I'm TimmyWit on HBT since she was my first.
Great story! Thanks for sharing. If you want my opinion, I don't think it's the recipe that has changed. (I think its a couple hundred years old!) It's your expanded tasting experiences. I have found the exact same thing to have happened. I mentioned Salvator in the OP. When I first tried it it seemed to be the nectar of the Gods. But I hadn't bought it in several years, and during that time I discovered many various styles that I had not tried before tasting Salvator, like sours, and imperial stouts, and I also became obsessed with anything and everything hoppy. So a few months ago I grabbed a sixer of Salvator, and surprisingly, was somewhat disappointed when I drank one. Still a very good dopplebock, but due to the evolution of my tastes, no longer anywhere close to a top 5 or 10 beer ever. In fact, a local micro brewery serves a dopplebock that I think is better!
