Is Beer Low FODMAP? What You Should Know Before You Crack One Open

Surprisingly, yes—some beer is low FODMAP in moderation. But not all beers are created equal, and how much you drink really matters.

Let’s break it down.

First, a Word About FODMAPs and Alcohol

Before we get into beer specifically, it helps to know how alcohol interacts with FODMAPs.

Alcohol itself isn’t a FODMAP, but many alcoholic drinks contain FODMAP ingredients, like fructose (in certain cocktails and ciders) or polyols (in some artificial sweeteners). Also, alcohol can irritate the gut, which means even low FODMAP drinks might not sit well for everyone.

So, while a drink may be low FODMAP, it doesn’t always mean it’s symptom-free for every person with IBS.

So, Is Beer Low FODMAP?

Yes—in small amounts, beer is considered low FODMAP. According to Monash University, a serving of 1 can or bottle (375ml) of regular beer is generally low FODMAP, even though it's made from barley or wheat.

Here’s why: During the brewing process, most of the FODMAPs (especially fructans) are broken down, making the final product lower in FODMAPs than the raw ingredients.

However, this only applies to traditional beer with moderate alcohol content. Stronger beers or flavored varieties may contain added high FODMAP ingredients like fruit juice, honey, or sweeteners—so always check the label.

What About Gluten in Beer?

Here’s where things get tricky. Beer is not gluten-free unless it’s specifically labeled as such. That’s fine if you’re only avoiding FODMAPs and not sensitive to gluten. But if you have celiac disease or non-celiac gluten sensitivity, you’ll want to avoid regular beer entirely—even if it’s low FODMAP.

Low FODMAP ≠ Gluten-free

If you need both, look for gluten-free beers made from rice, sorghum, or corn, but still check ingredients to ensure no high FODMAP additives are included.

Beer Types to Be Careful With

Some types of beer may be more likely to cause issues—even if technically low FODMAP:

⚠️ High-alcohol beers (like double IPAs or strong ales) – Alcohol can irritate the gut
⚠️ Fruit-infused beers – May contain high FODMAP fruits or juices
⚠️ Sweet or spiced beers – Added ingredients could include honey or high-FODMAP flavorings
⚠️ Craft beers – Some experimental brews contain unusual or undisclosed ingredients

Stick to simple, unflavored lagers or pilsners when in doubt.

Tips for Enjoying Beer on a Low FODMAP Diet

• Limit to one 375ml bottle or can per sitting
• Avoid beer on an empty stomach—pair with a low FODMAP meal
• Skip flavored or spiced varieties with questionable ingredients
• Watch how your body reacts—alcohol affects everyone differently
• If you’re sensitive to gluten, stick to certified gluten-free beers

Final Thoughts: Can You Drink Beer on a Low FODMAP Diet?

Yes—moderate servings of regular beer are low FODMAP. Just watch your portion size, avoid added high FODMAP ingredients, and be mindful of how alcohol affects your gut overall.

If you tolerate it well, there’s no reason you can’t enjoy an occasional cold beer—even while managing IBS.
