A pleasant aftertaste in beer is a matter of recipe design, brewing technique, and raw materials. Water chemistry is particularly important; trace metals in brewing water can lead to metallic aftertastes, and carbonate waters can give hop bitterness a lingering harshness. Improper sparging of the mash will release excess tannins, giving beer an astringent aftertaste.
Even the lightest of beers should possess an aftertaste, and it is up to the brewer to create impressions that beckon rather than repel. See also bitterness , sparging , umami , and water.
Garrett Oliver. If it is caused by aceto bacteria, then there is nothing to be done about it. Keep the fruit flies away from the fermentor next time. Diacetyl Diacetyl is most often described as a butter or butterscotch flavor.
Smell an unpopped bag of butter flavor microwave popcorn for a good example. It is desired to a degree in many ales, but in some styles mainly lagers and circumstances it is unwanted and may even take on rancid overtones.
Diacetyl can be the result of the normal fermentation process or the result of a bacterial infection. Diacetyl is produced early in the fermentation cycle by the yeast and is gradually reassimilated towards the end of the fermentation.
A brew that experiences a long lag time due to weak yeast or insufficient aeration will produce a lot of diacetyl before the main fermentation begins. In this case there is often more diacetyl than the yeast can consume at the end of fermentation and it can dominate the flavor of the beer. DMS is produced in the wort during the boil by the reduction of another compound, S-methyl-methionine SMM , which is itself produced during malting.
When a malt is roasted or toasted, the SMM is reduced beforehand and does not manifest as DMS in the wort, which explains why it is more prevalent in pale lagers. In other styles, DMS is a common off-flavor, and can be caused by poor brewing practices or bacterial infections. DMS is continuously produced in the wort while it is hot and is usually removed by vaporization during the boil. If the wort is cooled slowly these compounds will not be removed from the wort and will dissolve back in.
Thus it is important to not completely cover the brewpot during the boil or allow condensate to drip back into the pot from the lid. The wort should also be cooled quickly after the boil, either by immersing in an ice bath or using a wort chiller. When caused by bacterial infection, DMS has a more rancid character, more liked cooked cabbage than corn.
It is usually the result of poor sanitation. Repitching the yeast from an infected batch of beer will perpetuate the problem. Esters are produced by the yeast and different yeast strains will produce different amounts and types.
In general, higher fermentation temperatures produce more esters. Next batch, contrive to lower the fermentation temperature by a few degrees.
Grassy Flavors reminiscent of chlorophyll and fresh cut grass occasionally occur and are most often linked to poorly stored ingredients. Poorly stored malt can pick up moisture and develop musty smells.
Aldehydes can form in old malt and can contribute green grass flavors. Hops are another source of these green flavors. If the hops are poorly stored or not properly dried prior to storage, the chlorophyll compounds will become evident in the beer. These flavors are more evident in all-grain beers due to poor grain crushing or sparging practices.
If the grain husks are shredded during crushing by the use of a Corona grain mill for instance, these husk flavors are more likely to be extracted during the sparge. Follow the same procedures recommended to prevent astringency to correct the problem. Grainy flavors can also be contributed by highly toasted malts.
Hello, my name is Simon. Together with a group of writers I write about brewing beer and making wine. We all share a passion for the great things in life, such as making stuff from scratch.

What Does Beer Taste Like? Knowing this, I decided to study more about the taste of beer. What is The Taste of Beer?
Sweet Because beers are made with sugary substances such as yeast, which are then fermented into alcohol, many boast sweet flavors depending on the extent to which other substances are added and the brewing process that is used. Sour Many beers are also sour, largely due to the strains of yeast that are added and the addition of acid to the beer once the initial fermentation and brewing processes have been completed.
Fruity Several beers are also fruity. Does Beer Taste Good? The truth is that beer is an acquired taste. Is Beer Sweet or Savoury? Because yeast involves sugars, the substance adds a sugary flavor to beer. In some cases, hops are added to provide a more sophisticated and balanced flavor to a beer. It is barley that yeast pulls on to produce carbon dioxide and alcohol. German Pilsner German Pilsners are perfect options for those looking for more malty beers.
Amber American Lager Amber American lagers such as the Samuel Adams Boston Lager and the Yuengling Lager are produced with both light and medium hop flavors and a surprisingly smooth taste. These beers tend to have a higher sugar content and a darker color. Due to their sweetness and maltiness, Vienna lagers have only a mild hop flavor. English Brown Ale Another dark ale with a caramel scent, English brown ales such as the popular Newcastle Brown Ale are known for their strong nutty flavor and rich maltiness.
American Pale Ale In contrast to some of the darker beers above, American pale ales such as Smuttynose Shoals Pale Ale boast rich hop flavors and a light brownish color. Craft Beer From a Keg When compared to bottled or canned beer, craft beer from a keg, also called draft beer, tends to taste fresher and crisper.
Popcorn Strangely, some old beer can even taste like popcorn. Conclusion Rich, creamy, malty, sweet, sour, and bitter. Keep this guide in mind when you take your first sip—and cheers! How Long Does a Keg Last? Can You Still Drink It?
