What type of beer would haze typically indicate a problem with?

Haze in beer is often associated with specific styles and brewing processes. In the case of Pilsners, which are typically known for their clarity and crispness, the presence of haze can indicate a problem. Pilsners are finely filtered and generally should have a clean appearance. If a Pilsner shows haze, it may suggest issues such as poor filtration, oxidation, or the presence of yeast or proteins that were not properly removed.

Conversely, styles like IPAs, stouts, and wheat beers can naturally exhibit haze without it necessarily being indicative of a flaw. IPAs may have haze due to dry hopping and the use of certain grains, stouts often have a darker, opaqueness due to their malt content, and wheat beers traditionally have a cloudy appearance because of the wheat and yeast used in their production. Thus, haze in a Pilsner is a clear red flag for quality concerns, whereas in other styles it is more acceptable or expected.
