CLOUDY BEER: Beer in glass appears hazy, not clear:
Frozen or nearly frozen beer. Your beer may be suffering from Chill Haze. (NOTE: Chill haze happens when a beer is chilled below 35°F and polyphenols like tannins, are cross-linked through weak interactions such as hydrogen bonds to create larger particles. These polyphenols come mostly from your grain bill, but they also come from your hops. Often mistaken for yeast, this haze is temporary and doesn’t affect the flavor. Chill haze completely redissolves as the temperature rises and the bonds break up.)
Beer that has been un-refrigerated for long periods of time
Dirty faucet, beer line, and/or keg coupler
Your kegged beer has settled and excess hop material, dead yeast, or other beer adjuncts have accumulated at the bottom of the keg where the dip tube pulls your beverage. Subsequent pours should be clearer if this is the case.
FALSE HEAD: Large soap-like bubbles, head dissolves very quickly:
Dry glassware. Pro-tip: You can ‘wet’ your glass or rinse it with cold water before pouring.
Improper pour. Try pouring at a 45-degree angle in your glass.
