Beer Sediment: To Drink Or Not?

Sediment in beer is a common occurrence, especially in homebrews and craft beers, and sometimes it's even part of the style. Sediment is composed of yeast and protein particles that clump together and settle at the bottom of the beer or turn into floaties. While it may be aesthetically unpleasing, it is safe to consume and is not usually a negative trait. In fact, it is expected in many beer styles, such as German Hefeweizen, New England IPA, and Belgian beers, which are unfiltered. However, if the beer is old, the sediment may indicate that the beer is past its prime and the taste may be affected. To avoid ingesting sediment, it is recommended to store the beer upright and gently pour the beer, leaving the sediment undisturbed at the bottom of the bottle or can.

Sediment in beer is made of yeast and protein particles

Sediment in beer is primarily composed of yeast and protein particles. These particles are a result of the brewing process.

Bottle conditioning is a process where a small amount of active yeast and simple sugars are added to the bottle before sealing it off. This allows the beer to naturally carbonate and increase the ABV (Alcohol By Volume). After the fermentation is complete, yeast cells clump together and drop to the bottom, forming a thin cake. When the bottle is agitated, these particles are thrown back into the suspension and we see these sediments.

Aged beers are also bottle-conditioned and have yeast in suspension to ferment out any complex sugars present in the bottle. High-gravity beer styles such as barley wines, imperial stouts, and barrel-aged beers are ideal for cellaring and are dosed with yeast at the time of packaging.

In some styles, such as German Hefeweizen, Belgian Witbier, American Wheat, and Hazy New England IPA, beers are naturally cloudy post-fermentation and are traditionally served unfiltered. Unfiltered IPAs when dry-hopped have a lot of polyphenols from hops, which bond with proteins, creating a 'chill haze'.

Sediment is harmless and is even a good source of vitamin B. It is safe to consume and is acceptable in many beer styles. However, it is not recommended for those with a yeast allergy, as it may cause dizziness and breathing difficulties.

Sediment is safe to consume and can be beneficial to flavour

Sediment in beer is composed of yeast and protein particles that clump together and settle at the bottom of the bottle or turn into floaties. Sediment occurs when breweries choose not to filter or pasteurise their beer before bottling or kegging, or when it comes from bottle conditioning. Bottle conditioning is when sugar or wort (unfermented beer) is added to beer with live yeast. The yeast consumes the sugar, continuing the fermentation process and creating carbon dioxide, keeping the beer fresh for longer.

Sediment is perfectly safe to consume and can even be beneficial to the flavour of the beer. Many beers, such as Hefeweizens, are meant to have a nice dose of yeast mixed into the beer to complete the flavour profile. Yeast in some beer styles also enhances the visual appearance. Sediment is also rich in B vitamins, especially B12 and B9, which are good for humans.

However, some people find that the taste of the beer is cleaner and better without the sediment. If you want to avoid sediment in your beer, you can store the beer upright and let the sediment sink to the bottom. When it's time to serve, gently pour around two-thirds of the beer into a glass, then carefully tilt the bottle toward the glass, pouring the rest of the liquid until you see the sediment near the lip of the bottle. You'll lose about a sip of beer, but your drink will be clearer.

Sediment can be avoided by storing the beer upright

Sediment in beer is usually composed of yeast and protein particles that result from the brewing process. Sediment is not a negative trait and is even considered desirable in many beer styles. It is also safe to consume, even if it is the result of bacterial contamination. However, if the sediment looks like dandruff, the beer is likely too old and should be avoided.

Bottle conditioning can cause sediment

Bottle conditioning is a process where a small amount of active yeast and simple sugars are added to a bottle of beer before sealing it. In some cases, bottles are packaged while they are actively fermenting. Either way, this process allows the beer to naturally carbonate, and it can also increase the ABV (Alcohol By Volume).

The amount of sediment in bottle-conditioned beers can be minimised by using a high flocculating yeast, which sticks to the bottom of the bottle and forms a hard crust. Another technique is to cold crash the beer before bottling, which helps drop out suspended particles. Additionally, storing and serving the beer upright allows the sediment to settle at the bottom of the bottle, making it easier to avoid when pouring.

While sediment in bottle-conditioned beers is mostly unavoidable, it is not a negative trait and is perfectly safe to consume. In fact, drinking the beer with the sediment can provide an appreciation for the brewer's intended experience.

Sediment can indicate an old beer

Sediment in beer can indicate that the beer is old and should be avoided. While beer sediment is usually harmless and safe to consume, old beer sediment resembles dandruff and should be avoided at all costs.

Beers that are not suitable for ageing can turn stale, musty, and oxidised. The hop character fades away, and the protein particles clump together. This results in floaters that look like tiny snowflakes or similarly shaped flakes.

To avoid sediment in fresh beer, store the beer upright and let the sediment sink to the bottom. When serving, gently pour about two-thirds of the beer into a glass. Then, carefully tilt the bottle toward the glass, continuing to pour until you see the sediment near the lip of the bottle.

If you want to avoid sediment altogether, commercial beers that are force-carbonated are free from any sediment.
