Plain water is the safest, most reliable drink for people with GERD. It dilutes stomach acid, helps clear acid from the esophagus, and has no ingredients that trigger reflux. But water isn’t your only option. Several other beverages work well, and knowing which ones to avoid matters just as much as knowing what’s safe.
Water and Alkaline Water
Still water at any temperature is your baseline. It won’t irritate the esophagus, it helps wash acid back down into the stomach, and you can drink it freely throughout the day. If you want an extra edge, alkaline water with a pH of 8.8 can help neutralize pepsin, the digestive enzyme that damages esophageal tissue when it travels upward during reflux. Regular tap water typically has a pH around 7, which is neutral. The difference isn’t dramatic for most people, but if you deal with frequent throat irritation or a chronic cough from reflux, alkaline water may offer some additional relief.
Herbal Teas That Help
Caffeine-free herbal teas are a good choice. Ginger tea is a standout because ginger has natural anti-inflammatory properties and has long been used to settle the stomach. Chamomile tea is another mild, low-acid option that many people with GERD tolerate well. Licorice root tea (specifically the deglycyrrhizinated form, often labeled DGL) is sometimes recommended for its soothing effect on the stomach lining.
The key word here is caffeine-free. Regular black tea, green tea, and anything with caffeine can relax the valve between your stomach and esophagus, making reflux more likely. If you’re a tea drinker, swap to herbal varieties and see if your symptoms improve.
Low-Acid Fruit and Vegetable Juices
Not all juices are off-limits. The problem juices are citrus: orange, grapefruit, lemon, and tomato juice are all highly acidic and commonly trigger symptoms. But several alternatives sit much higher on the pH scale and are generally well tolerated.
Pear juice has a pH around 4.0 to 4.5, making it one of the milder fruit juices. Watermelon juice is even gentler, with a pH between 5.2 and 5.6. Both are naturally sweet without the acidity that irritates the esophagus. Aloe vera juice (in small amounts) is another option some people find soothing, though its taste is an acquired one.
Vegetable juices made from carrots, cucumbers, celery, or beets tend to be low in acid and high in water content. Carrot juice in particular has a mild, slightly sweet flavor that works well on its own or blended with other low-acid vegetables. Just avoid adding tomato or citrus to any blend.
Milk: Fat Content Matters
Milk has a complicated relationship with GERD. A cold glass of milk can feel soothing going down because it temporarily coats the esophagus and buffers stomach acid. But whole milk and other high-fat dairy can slow stomach emptying and increase pressure on the lower esophageal sphincter, which ultimately makes reflux worse. If you want milk, stick to skim or low-fat versions. Plant-based milks like almond, oat, or soy milk (unsweetened) are also reasonable alternatives, as they tend to be lower in fat and less likely to provoke symptoms.
Why Carbonation Is Risky
Carbonated drinks are a common trigger, and the reason is mechanical. The carbon dioxide gas expands in your stomach, causing distension. That stretch can trigger transient relaxations of the lower esophageal sphincter, the muscle that’s supposed to keep stomach contents from flowing back up. Studies have found that carbonated beverages significantly reduce pressure in this sphincter compared to flat drinks, increasing the frequency of reflux episodes.
This applies to all carbonated drinks: soda, sparkling water, seltzer, and sparkling cider. Even plain sparkling water with no added acid or sugar can cause problems through the gas alone. If you love the fizz, try letting your sparkling water go partially flat before drinking, or switch to still water entirely and see how your symptoms respond.
Coffee and Caffeinated Drinks
Coffee is one of the most frequently reported GERD triggers. Caffeine relaxes the lower esophageal sphincter, and coffee is also naturally acidic. Both factors work against you. Some people tolerate cold brew better than hot coffee because the brewing process produces a less acidic drink, but caffeine is still present. Decaf coffee removes one variable but not the acidity, so it’s worth testing your own response rather than assuming it’s safe.
Energy drinks combine caffeine with carbonation and often citric acid, making them a triple threat. If you need a caffeine source, small amounts of low-acid coffee or a mild caffeinated tea may be more manageable than soda or energy drinks, though reducing caffeine overall is the most effective move.
Alcohol and GERD
If you drink alcohol, what you choose matters. Beer and wine are strong stimulants of stomach acid production. Research from the Mayo Clinic found that beer stimulates acid secretion at a level equal to the stomach’s maximum output. Wine has a similar effect. Both are relatively low in alcohol concentration, and it turns out that low ethanol concentrations (under 5%) are what drive acid production most aggressively.
Higher-proof spirits like whisky, gin, and cognac do not stimulate gastric acid secretion or the release of gastrin (the hormone that triggers acid production). That doesn’t make them harmless for reflux, since alcohol in any form can relax the esophageal sphincter. But if you’re going to drink occasionally, a small amount of a higher-proof spirit mixed with a non-carbonated, non-citrus mixer is likely a better choice than a glass of wine or a beer.
When and How Much You Drink
Timing matters nearly as much as what’s in your glass. Drinking large volumes of any liquid with meals increases stomach distension, which raises the odds of reflux. Sipping smaller amounts during meals and drinking most of your fluids between meals can help. Avoid gulping large glasses of anything right before lying down. A good rule is to stop eating and drinking, especially anything acidic or caffeinated, at least three hours before bed. Nocturnal reflux tends to be more damaging because gravity isn’t helping keep acid in your stomach, and you’re less likely to notice symptoms until the irritation has already happened.
If you wake up with a sore throat, hoarse voice, or bitter taste in the morning, your evening drink habits are a good place to start making changes. Even shifting your last beverage of the day an hour earlier can make a noticeable difference.
