Why does tap beer give me a headache?

In this short article, we will provide an answer to the question “Why does tap beer give me a headache?” and the information on having beer safely.

Why does tap beer give me a headache?

Tap beer gives headaches because alcoholic beverages contain the chemical component Ethanol, which is responsible for the headaches you get after drinking a lot of beer. So, just to be clear, beer, like all alcoholic beverages, includes alcohol. While some beers contain as little as 3% alcohol by volume, most include at least 5% of the alcohol content.

When consumed in excess, congeners, a group of molecules other than ethanol, can also cause headaches or hangover symptoms.

What causes ethanol to cause headaches? 

So, when you drink beer or any other alcoholic beverage, you run the risk of getting a headache from the ethanol.


The initial vasodilator effect of ethanol is a good place to start. Because it’s a vasodilator, it widens your blood vessels by relaxing the smooth muscles within them, making it easier for blood to flow through. It is also possible that this vasodilation is causing headaches in certain people.


Second, ethanol is a typical diuretic, meaning that it increases the amount of water that is excreted from the body in the urine. The kidneys are now flushing out more than just water from the body; they’re also flushing out salts, nutrients, and minerals. Because of this, drinking a lot of beer can dehydrate you and cause a chemical imbalance in your body, which can lead to excruciating headaches.

Tap beer and bottled beer each have their advantages and disadvantages. Explain?

Beers that are poured from a tap or draught are known as tap beers or draught beers, respectively. Bottle beers are the ones that are stored in cans or bottles, contrary to popular belief. Some people prefer the flavor of tap beer, while others prefer the taste of bottled beer.

It is more difficult for UV light from the sun to permeate a keg or barrel of tap beer than it is for beer stored in glass bottles, which makes them more vulnerable.

There is no comparison between the cleanliness of bottled beer and the cleanliness of tap beer.

When it comes to portability, bottled beers have the upper hand over tap beers because the former can be brought anywhere, whilst the latter is extremely difficult to transport.

To make beer, what chemical processes are involved?

Chemically, beer contains vanillic acid and other phenolic acids 4-hydroxyphenyl-acetic acid, p-coumaric acid, syringic, sinapic, and ferulic acid.

More of the free compounds of phenolic acids can be found in alkaline hydrolysis tests, but the majority of the phenolic acids remain in their bound forms. 8-prenylnaringenin, a powerful phytoestrogen, is found in the beer brewed with it.

Malted barley contains the condensed tannins prodelphinidin B3, B9, and C2 that are used to make beer.

Brews contain a variety of aromatic higher alcohols, including tryptophol, tyrosol, and phenyl ethanol, which can be detected in small amounts. The Saccharomyces cerevisiae yeast produces these as a byproduct of the alcoholic fermentation process.

Any tips for drinking beer?

Following are the few most important tips to keep in mind if you drink beer:

  • Drinking beer has its own set of considerations.
  • Do not exceed your tolerance for alcohol by drinking more than you can handle.
  • Observe how clean your wine glasses or tap are before you begin to drink from them.
