Why Does Wine Make Me Sleepy the Ultimate Guide

Why Does Wine Make Me Sleepy? the Ultimate Guide

Wine is a popular drink, and if you enjoy drinking wine, you might sometimes wonder, “Why does wine make me sleepy?”

Because there’s melatonin in grapes, the primary ingredient of wines – especially red wine. 

The sleepiness you experience after drinking is caused by melatonin, a hormone that supports the maintenance of our circadian rhythm and sleep patterns.

Because it contains this hormone, we can infer that it has a sedative effect and makes you feel sleepy.

The Composition of Wine

In reality, wine contains 13 percent ethanol and 85% water. Other alcohols, leftover sugars, organic acids, phenolics, glycerol, sulfites, minerals, amino acids, and aromatics are some of the other substances that can be included in the remaining 3 percent of this composition.

The grapes themselves or the fermentation process are the sources of the majority of wine’s ingredients. Even though the additives are still in very small amounts, they are all added with care to maintain the 3% balance.

Wine contains 13 percent ethanol, which is produced during fermentation when yeast converts grape sugar to alcohol. Because yeast prefers glucose, some residual fructose that is produced during this process can be recognized as such.

Testing the sweetness of wine with a low sugar content may be dangerous because fructose is roughly 2.4 times sweeter than glucose.

Even though they make up just 3% of the total mixture, the components that make up this tiny portion are what give wine its special qualities. Of all the components that make up the three percent, glycerol takes up the most substantial space.

The viscosity of the wine is primarily caused by this component. The wine’s acidity or pH levels are caused by the organic acids that make up the remaining three percent. This component is used in the production of wine because grapes produce polyphenols as a defense mechanism and a signal that they are ready for consumption.

The levels of proteins and amino acids in wine grapes are also very high naturally. The presence of microorganisms, however, causes a significant depletion of these compounds during the fermentation process. As a result, they make up a relatively small portion of the three percent.

Wine and other alcoholic beverages are depressants that inhibit the functioning of our central nervous system (CNS).

The neurotransmitters of gamma amino butyric acid (GABA-A) will interact with these receptors to slow down neurons. And that’s when you start to feel at ease and sleepy.


Depending on the type of grapes used, each wine’s melatonin content may differ.

For instance, melatonin, which is primarily found in Italian red wines like Barolo and Barbaresco, was present in extremely high concentrations in the Nebbiolo grapes.

High levels of melatonin can be found in Merlot and Cabernet Sauvignon. However, red blend wines made from the Cabernet Franc grape have little melatonin in them.

Other (Possible) Effects

Hangover Headache

The high concentrations of tannins and phenolic flavonoid radicals in red wine are what cause the headache that comes with a hangover.

Red Wine Vs White Wine

Melatonin, which the brain also produces to promote sleep and support circadian rhythm and sleep cycles, is found in grape skins.

Crushed grapes, including grape skins, are used to make red wines. White wine is also produced from crushed grapes, but without the inclusion of the grape skins, which are eliminated prior to fermentation.

Therefore, it doesn’t have the same effect as red wines, which have higher melatonin levels than white wines, like Cabernet Sauvignon, which helps you sleep faster at night.

How to Drink Wine Without Being Sleepy?

While many people find that wine helps them regulate their body clock or get better-quality sleep, some people just want to drink without feeling sleepy afterwards.
