Is Tea Less Acidic Than Coffee? What’s in Your Cup?

There is a wave of people giving up coffee in favor of teas like green tea and black tea. Have you ever wondered if tea is less acidic than coffee?  We know that coffee and tea can stain our teeth and keep us awake, but what do these beverages do to our stomachs and tooth enamel? And which one is better in the long run?

Green tea and black teas are usually less acidic than coffee.  However, there are types of tea that are more acidic than coffee. This includes rosehip tea, most bottled iced teas, and fruit teas. 

There are other factors that matter when talking about the acidity of tea and coffee. The source of the tea and coffee matters when it comes to acidity, almost as much as the type of tea or coffee.

The nutrients that are in the soil as well as what the plants are treated with play a role. Not to mention that the damage done to your teeth and stomach varies with each type. 

Which Teas Are The Most Acidic?

The type of tea matters when talking about acid levels. Quite often, coffee has a fairly consistent acidity and pH level. But tea is a different story. Tea has many types and varieties that people enjoy drinking. Tea is also sourced from all over the world. 

The least acidic of the teas, typically, is green tea, followed closely by chamomile tea. Even though green tea is less acidic, it actually has as much caffeine as coffee, while chamomile has no caffeine and low acidity. 

The most common tea, black tea, is low on the acid scale and has moderate caffeine. Black tea has slightly less acid than coffee, so if you tend to have heartburn, you might opt for a cup of English Breakfast tea, rather than a mug of coffee. 

If you are concerned about the acidity of coffee and have switched to tea, it is important to make sure that you have not just switched to a type of tea that has a high acid level, because it might actually be more acidic than coffee.

How Do You Measure Acid Levels in Tea?

Acidity is determined by the pH scale.   The pH scale ranges from 0 (very acidic) to 14 (very basic or alkaline).  Water is right in the middle with a pH of 7.0 and is considered neutral.  

So, a drink that would be considered acidic would have a pH of less than 7.0. The lower the pH, the more acidic.  Most teas are mildly acidic, but some research shows that certain teas, especially bottled iced tea, may have a pH as low as 3, which is considered strongly acidic.

In general, most herbal teas that aren’t fruit based are lower in acid.

Since most fruit is naturally acidic, most fruit teas will be higher on the acid chart.

How to Lower the Acidity of Your Tea

If you’re concerned about the acidity of your tea there are several things you can do:

  • Cut down the brewing time
  • Dilute brewed tea with water, milk, or cream
  • Choose a tea with a higher pH level, like green tea, chamomile or mint
  • Don’t add lemon or other citrus flavorings

How to Lower the Acidity of Your Coffee

There are factors that play into making the coffee less acidic. If you are trying to make sure that your morning brew has the least side effects, then try out these tips. 

Low Elevation Beans

Coffee beans that were grown at lower elevations have naturally lower acidity. This has to do with soil nutrients. Finding out the elevation of the plants will have to do with the country of origin. Mountainous growing regions will have higher growth elevations. 

Dark Roast

The longer a bean is roasted, the lower the acidity of the coffee and the lower the caffeine. While a blonde roast may be smoother, it is actually more acidic. 

Cold Brew

Cold-brew is a popular choice right now. It is easy to make at home and is less acidic than a traditional brew. Cold brews are a great way to start your morning or to have a low acid afternoon pick me up.

Add Salt

If you are trying to lower the acidity of your morning cup of coffee, you can add some salt to the grounds before you brew. Just a little bit will go a long way, and you won’t have salty coffee. This is a coffee hack that anyone can try today. 

Egg Shells

Another brewing hack to lower the acidity of your coffee is to brew with eggshells. The eggshells are high in calcium, and that cuts acidity. The key is to make sure you have rinsed the shells well to make sure all of the egg is gone. 

How Acidic Tea & Coffee Affect Acid Reflux

People that already suffer from different conditions that cause acid reflux typically stay away from tea and coffee because they are too acidic. But do they have to? When it comes to tea, while it has caffeine and certain levels of acidity, it is actually much better for heartburn sufferers than coffee. 

However, it isn’t because of the acid levels or caffeine. Even though coffee has a stimulant in it, it is also a type of muscle relaxer. There is a muscle between the stomach and the esophagus, and when it relaxes, it allows the stomach acid to move back up the esophagus, causing heartburn. 

Some people say the reason coffee causes heartburn is because of the acid or even the caffeine, but that isn’t the case. Even decaf has been known to cause heartburn in some people.

Does Acid in Tea and Coffee Affect Bone Density?

Another aspect of consuming acidic beverages such as tea and coffee is the concern for bone density. It isn’t clear if it has to do with the acid levels of coffee or something else, but typically those that drink coffee often will have lower bone density than tea drinkers. 

This seems to be the case even though some teas are higher in acidity than coffee. If you have a history of bone loss in your family or other risk factors, then you may want to stick with a low acid tea. 

Ask your doctor which teas are the safest for you to drink or avoid if you have bone density problems.  

Are Coffee and Tea Harmful to Teeth?

The truth about your teeth when it comes to coffee and tea is more complicated than some people think. Your teeth do stain because of the color of the beverages but how it affects your enamel is the bigger issue. 

Tea has a wider range of pigments than coffee does. Coffee is just black or dark brown, while tea carries varied pigments. Because of the pigments and the acid, tea may harm your enamel faster than coffee will. 

Coffee might stain your tea faster, but that is just because it is darker, typically than coffee. One way that you can combat this damage without giving up tea and coffee is to drink your beverage through a straw. 

Worried About Your Teeth? Don’t Do This

Did you know that there are certain ways of drinking tea and coffee that can harm your tea more than others? These methods tend to let the drink linger in the mouth and around the teeth, increasing the time your teeth are exposed to the acid. 

Swishing Tea or Coffee

Swishing tea or coffee around in your mouth like mouthwash is not a good way to protect your enamel from the acid. It is just the opposite. This will bathe your teeth in the acid and pigments that will can damage the enamel. 

Holding Tea or Coffee in Your Mouth

While those who love coffee and tea may want to savor the beverage for a little bit longer, it is not wise to hold the tea or coffee in their mouths. As with swishing the liquid around in your mouth, your teeth are being exposed to the acid for a long period. This will further weaken the teeth as well as stain them. 

Brushing Immediately After Drinking Tea or Coffee

No one likes coffee breath, but did you know it is bad for your teeth to brush right after coffee or tea? Because these beverages are acidic, some more so than others, if you brush right after, you will remove some of the newly weakened enamel. 

The Good News:  There’s Always a Low Acid Choice with Tea

While it is true that some types of tea are more acidic than others, there are many choices like green tea, chamomile, and mint tea that are low on the pH scale.

Even if you must have that super strong cup of black tea or coffee, there are things you can do to lower the acidity levels. 

Thankfully, there’s no reason to give up that morning caffeine unless you just want to.
