Water is the safest and simplest drink for GERD, and herbal teas, plant-based milks, and low-acid juices round out a short list of reliably gentle options. The trickier part is knowing which popular beverages quietly make reflux worse, sometimes through mechanisms that have nothing to do with acidity.
Why Beverages Matter for Reflux
GERD symptoms flare when stomach acid escapes upward through the lower esophageal sphincter (LES), the muscular valve between your esophagus and stomach. Some drinks relax that valve, letting acid slip through. Others ramp up acid production in the stomach itself. A few do both. Choosing the right beverages is one of the simplest daily changes you can make because you’re probably drinking something every hour or two.
The Best Options
Plain and Alkaline Water
Regular water dilutes stomach acid without triggering more of it. It’s pH-neutral, caffeine-free, and won’t relax the LES. If you want an extra edge, alkaline water with a pH of 8.8 permanently deactivates pepsin, the stomach enzyme responsible for much of the burning damage in reflux. A lab study published in the Annals of Otology, Rhinology, and Laryngology found that pH 8.8 water irreversibly shut down human pepsin and buffered hydrochloric acid far better than conventional water. That doesn’t mean you need to buy specialty water every day, but keeping some on hand for flare-ups is reasonable.
Temperature matters more than most people realize. Research on esophageal motility shows that warm and hot liquids reduce resting pressure in the LES and help it relax normally, while cold drinks increase LES pressure and can prolong esophageal contractions. Sipping warm or room-temperature water is gentler on a sensitive esophagus than ice water.
Herbal Teas
Ginger, chamomile, and licorice root teas are the three most commonly recommended herbal options. Ginger supports faster gastric emptying, meaning food moves from your stomach into your small intestine more quickly. Once that happens, the stomach no longer needs to churn out acid to digest it, which reduces the chance of acid washing back up. Ginger also has mild anti-inflammatory properties that can soothe irritation already present in the esophagus. To make ginger tea, steep fresh peeled ginger in boiling water for about 15 minutes and sip it in small amounts.
Chamomile tea is naturally caffeine-free and has a calming effect on the digestive tract. Licorice root tea (specifically the deglycyrrhizinated form, often labeled DGL) coats the esophageal lining. One important exception: peppermint tea relaxes the LES and is a known reflux trigger, so skip it despite its reputation as a digestive aid.
Plant-Based Milks
Soy milk and almond milk are both alkaline-forming in the body, making them solid choices. Oat milk and cashew milk are actually acid-forming, so they’re not as ideal, though many people tolerate them fine. Coconut milk depends on how it’s processed: fresh coconut is alkaline-forming, while dried or heavily processed coconut milk tends to be acid-forming.
Dairy milk is more complicated than it seems. It has a near-neutral pH of about 6.7 to 6.9, and the fat temporarily coats the esophagus, which can feel soothing in the moment. But milk stimulates the stomach to produce more acid afterward, often making symptoms worse within 30 to 60 minutes. If you prefer dairy, low-fat or skim versions cause less rebound acid production than whole milk.
Low-Acid Juices
Not all juice is off-limits. The key is choosing varieties with naturally higher pH levels. Good options include carrot juice, aloe vera juice, cabbage juice, and fresh juices made from beets, watermelon, spinach, cucumber, or pear. These sit well above the acidity threshold that irritates an already-inflamed esophagus. Coconut water is another gentle choice with a mild flavor and low acidity.
Smoothies
Blending low-acid fruits like bananas, melons, and pears with a plant-based milk gives you a filling drink that won’t provoke reflux. Avoid adding citrus, tomato, or chocolate to the mix. A handful of spinach or a slice of fresh ginger blends in without changing the taste much and adds the benefits mentioned above.
What to Avoid and Why
Coffee
Coffee is one of the strongest stimulants of gastric acid production. Caffeine relaxes the LES, but it’s not the only problem. Coffee contains phenolic acids, including chlorogenic acid and caffeic acid, that independently boost stomach acid and weaken the valve. Switching to decaf helps significantly. One study found that decaffeinated coffee reduced the time acid spent in the esophagus from 17.9% down to 3.1% compared to regular coffee. That’s a dramatic difference, though decaf still contains those phenolic acids in smaller amounts, so it may not be completely symptom-free for everyone.
Alcohol
Alcohol both loosens the LES and directly irritates the esophageal lining. The American College of Gastroenterology lists it as a clear trigger and recommends stopping alcohol consumption entirely for people with active GERD. Beer and wine tend to be worse than spirits because of their higher volume and carbonation (in beer’s case), but no form of alcohol is truly safe for reflux.
Carbonated Drinks
Soda, sparkling water, and seltzer all introduce gas into the stomach, causing it to stretch. That distension triggers transient relaxations of the LES, brief openings that let acid escape upward. Studies have found that carbonated beverages significantly reduce LES pressure compared to flat drinks and can acutely lower the pH inside the esophagus. Even plain sparkling water carries this risk, so if you love fizz, it’s worth testing whether flat water improves your symptoms.
Citrus and Tomato Juice
Orange juice, grapefruit juice, lemonade, and tomato juice are highly acidic, with pH values often between 2.0 and 4.0. Apple juice falls in the 3.35 to 4.0 range, which is acidic enough to irritate a damaged esophageal lining. These juices don’t just add acid to the stomach; they can directly burn tissue that’s already inflamed from repeated reflux episodes.
Chocolate-Based and Mint Drinks
Hot chocolate, chocolate milk, and peppermint tea all relax the LES. Cocoa is also a potent stimulant of gastric acid production. Mint-flavored drinks, including some commercial iced teas, carry the same risk even in small amounts.
Practical Drinking Habits
What you drink matters, but how and when you drink it also shapes your symptoms. Sipping smaller amounts throughout the day puts less pressure on the stomach than gulping a large glass at once. A full stomach pushes acid toward the LES, so drinking large volumes with meals can be worse than the same volume spread across the day.
Timing around bedtime is especially important. Finishing your last drink at least two to three hours before lying down gives your stomach time to empty. If you need something closer to bed, a small amount of warm chamomile or ginger tea is a better bet than a full glass of milk or juice.
Keeping a simple log of what you drink and when symptoms appear can reveal personal triggers that don’t match general advice. Some people tolerate small amounts of decaf coffee with no issues, while others find even chamomile tea problematic. GERD triggers vary enough from person to person that your own data is the most useful guide after you’ve eliminated the major offenders.
