Is Whiskey Acidic

Is whiskey acidic? Whiskeys, like other alcoholic beverages and distilled spirits, can have an aggressive burning sensation when taken. And when we think about it, you might think it must be very sour, similar to lemonade or any other sour refreshment.

But is whiskey acidic? 

The team spent many hours gathering all the information we can provide for you. 

All About Whiskey and Acidity 

Whiskey is a kind of distilled beverage that is from grains. The fermented grains are being distilled, and then it is mixed with water. The fermented grains that contain enzymes will break down into starches down to sugars when cooked.  

Whiskey Distillation Process

Whiskeys are the result of the fermentation and aging process, by that it releases chemicals with some acidic properties. Also, since whiskey is composed of ethanol and water, alcohol plays a huge role in contributing acid to whiskey.

Is Whiskey Acidic or Basic? 

We’ve heard about a lot of people asking about whether whiskey is acidic. As whiskey is primarily consisted up of water and ethanol, it does not appear to be acidic. But this is deceptive because it implies that whiskey is pure water and ethanol, which isn’t. Barley, for example, has a lower pH of roughly 5.6, while barley mash has a lower pH of 5 to 5.5.

A study states that before being matured, whiskey’s acid level ranges from 4.4 to 5.1. It only indicates that whiskey is truly acidic. 

Factors That May Affect Its Acidity Level

Factors That May Affect Its Acidity Level


During aging, wood barrels are extracting Carboxylic. It can also be produced by yeast during fermentation. This means that, as long as the whiskey is aging inside the barrel,  it will also keep producing carboxylic acid, which triggers the ph level of the whiskey. 

According to a study of Bourbon and Whiskey, before being matured, whiskey had pH levels covering from 4.4 to 5.1. After 48 months, the pH levels ranged from 4.0 to 4.45. These pH levels indicate that an old whiskey is more acidic as it ages. It has a slightly higher level than black coffee but is lower than lemon juices.

Whiskey Decanters

It’s usual to see a bar table with a bunch of decanters filled with other alcohols like Bourbon. Usually, decanters are used for wine to allow the liquor or beverage to breathe. This process can unleash the wine’s aromas while also altering the drink’s flavor profile.

But decanters do not affect the flavor and taste profile of the whiskey. While the whiskey may breathe slightly, it’ll not taste different than it did straight from the bottle. But, how much whiskey will it really take to get you drunk?


The wine barrels that were made from European oak give acidic notes to the liquid-like orange and lime. By this, the normal scale of acid of the drink may increase quite a bit, somehow.

In terms of whiskey flavor profiles, sweet, fruity, spicy, oaky, or smoky are used to describe the whiskey’s profile. And these flavors came from the oak casks that were used during their maturation. 


When producing whiskey, the spirit is being matured in wooden barrels before bottling. Oak barrels specifically are used in Bourbon. Upon aging in barrels, the acidity may increase due to its oxidation. 

Whiskey Bottle Production Process

However, once the whiskey is bottled, the aging process stops in the liquid, and with this, the development of acid also stops.

Specific brands of whiskey have significant variances in acidity levels. Here’s a summary of a few famous whiskeys

The range of pH levels does not vary dramatically between brands or ages of whisky. 


Which is less acidic, beer or whiskey?

Whiskey is less acidic than beer. It is because of the fermentation process, as well as the inclusion of sugars and wheat.

Wheat is the most acidic ingredient in beer. Lagers have a pH range of 4.0 to 5.0, while the Belgian beers are 3.5. So is whiskey healthier than beer then?

Which is less acidic, whiskey or wine? 

Whiskeys are less acidic than wines because they contain sugar and yeast. The sugar is what raises its acid level. White wines with a high glucose level have around 3.0. The pH of light-bodied whites is 3.1, whereas the pH of other red wines is 3.5. But what’s the best whiskey for a Whiskey Sour?

Is cider more acidic than whiskey? 

Yes, ciders are more acidic compared to whiskeys. The pH level of cider juice is usually between 0.3 and 0.5. The lower a substance’s pH level is, the more acidic it is. A pH level greater than 7 renders the liquid basic or alkaline.

Is whiskey acidic or alkaline?

Whiskey is acidic. The pH of whiskey typically falls within the acidic range, contributing to its distinct taste profile.

Does whiskey cause acidity?

Whiskey can contribute to acidity in the stomach, potentially triggering acid reflux or heartburn in some individuals. However, the impact varies among people, and moderation is key.

Is vodka acidic or alkaline?

Vodka is typically considered neutral, falling close to the middle of the pH scale. It is neither highly acidic nor alkaline.

Is scotch acidic or alkaline?

Scotch, like other whiskies, is acidic. Its pH level contributes to the overall flavor profile, and it may have similar effects on acidity as other types of whiskey.

Is beer acidic?

Beer is mildly acidic. It generally falls on the acidic side of the pH scale, but the acidity levels are relatively low compared to some other alcoholic beverages.

Which whiskey is less acidic?

The acidity of whiskey can vary among different brands and types, but specific information on the acidity of various whiskies may not be readily available. Generally, personal taste preferences and individual reactions to different whiskies should guide choices.

What alcohol is the least acidic?

Vodka is often considered one of the least acidic alcoholic beverages. Its neutral flavor profile is accompanied by a pH level close to neutral on the scale.

Which is more acidic, whiskey or beer?

Whiskey is generally more acidic than beer. While beer is mildly acidic, the acidity level in whiskey tends to be higher due to its production process and composition.

Is vodka more acidic than whiskey?

No, vodka is not more acidic than whiskey. Vodka is typically neutral, with a pH close to neutral on the scale, while whiskey tends to be more acidic.

Which alcoholic drink is most acidic?

Among commonly consumed alcoholic beverages, wines and some spirits, particularly whiskies, tend to be more acidic. However, the acidity level varies among different types and brands.

Is whiskey OK for acid reflux?

For some individuals, whiskey may trigger acid reflux or worsen symptoms due to its acidic nature. It is advisable for those with acid reflux issues to consume alcoholic beverages in moderation and be aware of personal triggers.

What alcohol is OK for acid reflux?

Individuals with acid reflux may find that low-acid options, such as vodka or gin, are more tolerable. However, reactions can vary, and moderation is essential.

Does Jack Daniels have acid?

Yes, Jack Daniels, like other whiskies, has an acidic nature. The pH level contributes to its overall flavor and can potentially impact individuals sensitive to acidity.

Is coffee acidic?

Yes, coffee is acidic. The natural acids present in coffee contribute to its characteristic taste. However, the acidity level can vary among different coffee beans and brewing methods.

Is coffee an alkaline or acid?

Coffee is generally acidic, but some coffee enthusiasts aim to reduce acidity by choosing specific bean varieties or using brewing methods that result in a less acidic cup.

Which alcohol does not cause acidity?

While individual reactions vary, spirits like vodka or gin, which are generally neutral and low in acidity, may be better tolerated by individuals prone to acidity issues. However, moderation is crucial.

So, Is Whiskey Acidic? 

The answer is yes. However, it is not as acidic as other alcohols or drinks such as beer and wine. Since most whiskeys are composed of ethanol (drinkable alcohol) and water, their pH scale is neutral. Although in some cases, acids react differently with other compounds, causing corrosive reactions. [1] 

This pH level in whiskey can rise during the maturing procedure and can be affected by other factors such as coloring and flavorings.
