The best drinks during acid reflux are plain water, low-fat or plant-based milks, ginger tea, and low-acid vegetable juices. What you avoid matters just as much as what you choose, and even the amount you drink at one time can make a noticeable difference in how you feel.
Water Is the Simplest Option
Plain water dilutes stomach acid and helps clear it from the esophagus. It’s the safest, most reliable choice during a flare-up. Room temperature or slightly warm water tends to work best. Very cold beverages can trigger esophageal spasms in some people, which makes the discomfort worse.
Alkaline water, with a pH of 8.8 or higher, offers an extra benefit. During reflux episodes, a digestive enzyme called pepsin can get lodged in the tissues of the esophagus, where it continues damaging the lining even after the acid itself is gone. Alkaline water at that pH level helps neutralize pepsin’s effects, giving the tissue a chance to recover. You can find bottled alkaline water in most grocery stores, or make it at home with pH drops.
Low-Fat and Plant-Based Milks
Milk often feels soothing going down, but the type of milk matters. Whole milk contains enough fat to relax the muscular valve between your stomach and esophagus (called the lower esophageal sphincter), which actually lets more acid escape upward. It also slows stomach emptying, keeping acid in contact with sensitive tissue longer.
Skim milk is a better option. Its calcium and protein content can help neutralize stomach acid and may even improve the tone of that valve over time. It contains less than 0.5 grams of fat per serving, which avoids the valve-relaxing problem of full-fat dairy.
Unsweetened almond milk is another strong choice. It has a naturally alkaline pH of about 8.4, compared to cow’s milk at 6.8, so it does more to counteract acidity in the esophagus. Other plant-based milks like oat or coconut can work too, as long as they’re unsweetened and low in fat. Avoid flavored or sweetened versions, which can increase acid production.
Ginger Tea and Other Herbal Teas
Ginger has a long track record as a digestive aid, and ginger tea is one of the most popular home remedies for reflux symptoms. The research on exactly how ginger works in the stomach is mixed. Some studies show it can speed up gastric emptying in certain patients, which reduces the window for acid to splash upward. Clinical trials have used doses ranging from 250 mg to 1 gram per day, with no added benefit from going higher. A thumb-sized piece of fresh ginger steeped in hot water for 10 minutes falls comfortably in that range.
Chamomile tea is another option worth trying. It has mild anti-inflammatory properties and, unlike peppermint tea, doesn’t relax the esophageal valve. Peppermint tea is one to skip entirely during reflux, as it can make symptoms worse. Licorice root tea (specifically the “deglycyrrhizinated” or DGL variety) is sometimes recommended for coating and protecting the esophageal lining, though the evidence is more anecdotal than clinical.
One important note on all teas: let them cool to a comfortable drinking temperature. Very hot liquids can irritate an already inflamed esophagus and potentially trigger spasms.
Low-Acid Juices
Citrus juice, tomato juice, and most fruit juices are highly acidic and will almost certainly make your symptoms worse. But several vegetable-based juices have a much higher pH and can be gentle on the esophagus. Good options include carrot juice, cabbage juice, and freshly made juices from beets, watermelon, spinach, cucumber, or pear.
Aloe vera juice deserves a special mention. In one clinical trial, patients who added aloe vera to their treatment regimen experienced significantly greater symptom improvement than those on standard medication alone. By the end of six weeks, nearly 72% of the aloe vera group had their symptom scores drop below the threshold for clinical concern. No side effects were reported. Look for inner-leaf aloe vera juice with no added sugars or citric acid, and start with small amounts (a few tablespoons) to see how you tolerate it.
Drinks to Avoid
Coffee, both regular and decaf, stimulates acid production and relaxes the esophageal valve. Carbonated drinks introduce gas into the stomach, increasing pressure and making reflux more likely. Alcohol, particularly red wine, is a well-documented trigger. Citrus juices, lemonade, energy drinks, and sweetened sodas are all highly acidic.
If you’re not ready to give up coffee entirely, cold brew tends to be less acidic than hot-brewed coffee. Drinking it with a splash of low-fat milk can help buffer the acidity further. But during an active flare-up, it’s best to avoid it altogether.
How Much You Drink Matters Too
It’s not just about what’s in your glass. The volume you drink in one sitting has a direct effect on reflux. A study comparing meal sizes in reflux patients found that consuming 600 mL (about 20 ounces) of liquid at a time produced significantly more reflux episodes and nearly double the total acid exposure compared to drinking 300 mL (about 10 ounces) spread across more frequent sittings. The larger volume stretched the upper portion of the stomach more, creating greater pressure against the esophageal valve.
The practical takeaway: sip smaller amounts throughout the day rather than gulping large glasses with meals. If you’re eating a full meal, keep your drink to about 10 ounces and finish the rest between meals. This simple habit change can reduce reflux episodes without changing what you’re drinking at all.
Putting It Together
During an active flare-up, your best immediate options are room-temperature water (alkaline if you have it), unsweetened almond milk, or a mild ginger tea that’s cooled slightly. For ongoing management, work low-acid vegetable juices and aloe vera juice into your routine, keep portion sizes small, and minimize coffee, alcohol, and carbonated drinks. The combination of choosing the right beverages and controlling how much you drink at once gives you two separate levers to pull, and using both together tends to produce the most noticeable relief.
