Others argue that filtration effectively removes haze without any appreciable effect on beer flavor. Check out the Clarifier Summary Chart below for a more complete list.
When brewing a show beer to be judged in a homebrew competition or served at a wedding by those who are less understanding or forgiving than your fellow homebrewers, filtration could become not just desirable, but essential.
If you choose to filter your beer, know that small-scale filtering systems are available, but they require that you keg and force carbonate your beer.
However, theory and practice are two different things. Filters can effectively remove particles of any size from beer, but as you move to ever-finer filters, the risk of stripping away flavor increases.
Filter fineness is expressed in terms of microns—one micron is one-millionth of a meter or 0. Yeast cells are relatively large, ranging from about three to 20 microns in size. By contrast, even the largest proteins and polyphenols are smaller than a yeast cell, and the smallest are more than 1, times smaller at 0. Homebrewers typically use filters sized at 5, 1, and 0. You can also filter out bacteria before they become a problem.
Bacteria are relatively large, ranging from about 0. Remember, we drink with our eyes first. Want to enjoy exclusive access to member-only content and more?

Suspended particles and yeast will drop out of suspension as the beer is chilled. Of course chilling down a fermenter will require refrigeration so unless you have a fridge to ferment your home brews in cold crashing may not be possible.
Cold crashing in this way also helps to prevent chill haze later on after the beer has been bottled. The answer to this question is no. Unless there is a microbial haze caused by bacteria, the taste is going to be the same whether the beer is hazy or clear. The fact is though, brewers have to add finings, cold crash fermenters and manipulate the beer by filtering it to get it clear.
It could be argued that some of these measures remove flavour, so is it worth it? A lot of what you taste is affected by the way something looks, if you prefer clear then try some of the method above.
Thanks Neil, very interesting article. I learnt something new in the first paragraph. Glad you found the article interesting. In the UK most pubs will only sell crystal clear cask beer.

This basically means altering the recipe to use less protein-heavy malt grains or adjuncts and to use fining and cold crashing to force compounds to drop out of suspension in your beer. The popularity of these types of beer has risen recently for a few reasons.
Another reason why cloudy beers are popular with homebrewers is that they help hide a few basic mistakes that we are all or were guilty of in the beginning. The types of yeast that are usually used for these types of beers are low-flocculation. There are 3 categories of flocculation levels high, medium, and low.
The low one used for cloudy beer usually does not start to start to flocculate before 15 days. Most wild yeasts you find fall into this category. The one issue with them is that they are hard to filter. However, there are many more strains which you can find out there which will give you a lovely cloudy finish.
So the jury may be out on whether it adds or subtracts from the drinking experience. If the beer has been bottled conditioned, that sediment is more than likely the dormant yeast. In other beers it is not meant to be there. You can read more about how to move your beer from the fermenter to the bottling bucket in my article here.
It also occurs with a bad grain bed and sparging process from the mash turn to the brew kettle pre-boil in all-grain brewing. To avoid this from happening altogether, consider switching to BIAB brewing see my article here. Also, from movement, sometimes if the beer has settled in the bottle and then gets shaken around cloudiness can appear. This will happen if you are pouring it into a glass from the bottle.
Since you have happened upon this page about drinking your homebrew, I assume that you have a passion for brewing. It is a great hobby and you want to get better at it so you and everyone can enjoy your beer. The only way to do this is to know what you did wrong or where you can improve is to take notes. Take notes from the start to when you are drinking your beer, so you can research ways to improve it. This is especially true if you make the same beer several times, which is advisable to hone your skills.
If it turns out differently each time, you can use your brewing notes to figure out the cause. Hey, I'm Phil. I'm passionate about all things beer.
I love making it, drinking it and best all, learning about it! A hydrometer is perhaps THE most important piece of brewing kit you'll ever own, yet some homebrewers never even use them.
