About 7 years ago I had this great tasting beer that kind of tasted like sourdough pretzels . I would like to buy this beer again but can’t remember the name.
Sounds like a farmhouse ale:
Go to a well-stocked store, buy one six-pack of each style of beer they have, and keep going until you rediscover the lost brew or find something else you like.
Can you remember anything else about it? Color? Label?
Where did you have it? Any idea if it was local or imported?
Sourdough pretzels is unfortunately not much to go on. Best you can probably hope for is to describe it in more detail and we can recommend something similar.
