One of the biggest improvements in my brewing came when I learned about the importance of getting a good "cold break". A "cold break" is when you cool down the wort very quickly and precipitate proteins out of solution. Getting a good could break can be tricky, but good 'ole Wisconsin winters can really help cool down your beer. If a beer is cooled to pitching temps slowly, these protein will remain in suspension in the beer, causing it to look hazy when chilled. Chill haze is a cosmetic issue, not something you can taste or perceive other than visually, however many brewers like to have clear beer. Can you blame them?
