Is tea acidic?

Yes — but only mildly. Most brewed teas sit in the mildly acidic range, roughly pH 5 to 6.5, where 7 is neutral. That is a long way from the things people actually worry about. Your stomach's own acid is far stronger (around pH 1.5 to 3.5), and everyday drinks like soda, fruit juice and even coffee are all more acidic than a typical cup of tea. So while tea is not perfectly neutral, it is one of the gentler things you can drink.

The pH of different teas

"Tea" is not one number — acidity shifts with the leaf and with what you add:

• Black tea — the most acidic of the common teas, usually around pH 5, roughly on par with a mild coffee.
• Green tea and oolong — generally a touch less acidic than black, with lighter oolongs sitting in between.
• Herbal and fruit infusions — these vary the most. Gentle herbals like chamomile and peppermint are often close to neutral, while hibiscus and fruit blends can be noticeably more acidic.
• With lemon — a squeeze of lemon makes any cup distinctly more acidic; lemon juice itself is strongly acidic.
• With milk — adding milk raises the pH, making the cup less acidic and gentler on teeth.

Does tea's acidity actually matter?

For most people, tea's mild acidity is nothing to lose sleep over. Two situations are worth a mention — with the reminder that this is general information, not medical advice:

• Teeth. Any acidic drink can, over time, soften tooth enamel. Sipping tea slowly all day gives acid far more contact time than enjoying a cup in one sitting. Adding milk and rinsing with water afterwards both help.
• Acid reflux and sensitive stomachs. Strongly brewed black tea, and its caffeine, can be a trigger for some people. Lighter brews, green or herbal teas, and not drinking on an empty stomach usually make it easier.

How to brew a less acidic cup

• Reach for green or herbal over a strong black tea when you want something gentler.
• Don't over-steep — a shorter brew pulls out less, for a milder, smoother cup.
• Add a splash of milk — it lifts the pH and softens the acidity.
• Go easy on lemon if your stomach or teeth are sensitive.
• Enjoy it in a sitting rather than nursing one cup all morning — kinder to your teeth.

Common questions

Is green tea acidic?

Only mildly, and usually a little less than black tea. Many herbal infusions are gentler still, sitting closer to neutral.

Is tea bad for acid reflux?

For some people, strongly brewed black tea and its caffeine can trigger reflux. Lighter brews, green or herbal teas, and not drinking on an empty stomach usually help, but if reflux is ongoing, check with a doctor.

Does adding milk reduce tea's acidity?

Yes. Milk raises the pH of the cup, making it less acidic and gentler on tooth enamel.

Which tea is the least acidic?

Many herbal infusions like chamomile and peppermint are closest to neutral. Among true teas, green is generally gentler than black.
