Gluten is a protein found in wheat, rye and barley that those with celiac disease or an intolerance to gluten must be careful to avoid.
Though wine is naturally gluten-free, winemakers may use processes that add gluten to the finished product.
This article explains how wine is made and factors that may affect its gluten-free status.
Made From Gluten-Free Ingredients
1. Crushing and pressing. This extracts the juice from the grapes. When making white wine, the juice is quickly separated from the grape skins to avoid color and flavor transfer. When making red wine, color and flavor are desirable.
2. Fermentation. Yeast, which is gluten-free, converts juice sugars to alcohol. Sparkling wine undergoes a second fermentation process to make it bubbly. Fortified wine like sherry contains distilled alcohol, which is also gluten-free.
3. Clarification. This makes wine clear rather than cloudy. The most common method to achieve this is fining, which involves using another substance to bind and remove unwanted elements. Various fining agents can be used.
4. Aging and storage. Wine may be aged in stainless steel tanks, oak barrels, or other containers before bottling it. Stabilizing agents and preservatives, including sulfur dioxide, may be added but are typically gluten-free.
While wine ingredients are gluten-free, contamination with gluten may be possible during processing and storage.
Wine is made from grapes and sometimes other fruits, which are naturally gluten-free. However, there are concerns about the potential for gluten contamination during processing and storage.
Possible Contamination During Fining
Fining is a process that removes unwanted elements, such as proteins, plant compounds and yeast, to ensure wine is clear rather than cloudy and smells and tastes good (1).
Fining agents bind to unwanted elements, which then drop to the bottom of the wine and can easily be filtered out.
Gluten itself can be used for fining, but it's rare. When used as a fining agent, gluten largely remains behind as sediment at the bottom of the storage container when the wine is filtered and transferred to bottles.
Studies suggest that the remaining gluten after fining falls below 20 parts per million (ppm) or 0.002% — the limit set by the Food and Drug Administration (FDA) for labeling items gluten-free (5, 6, 7, 8).
However, a small subset of people with celiac disease is sensitive to trace amounts of gluten below 20 ppm. If you fall into this category, ask the winery what they use for fining or purchase certified gluten-free brands (9, 10).
Most wine sold in the U.S. is regulated by the Alcohol and Tobacco Tax and Trade Bureau (TTB). Varieties that contain less than 7% alcohol by volume are regulated by the FDA (11).
The TTB only allows gluten-free labeling if no ingredients containing gluten are used and care is taken to avoid cross-contamination with gluten during alcohol production (12).
Common fining agents include egg, milk and fish proteins, as well as bentonite clay. Occasionally gluten is used for fining, and tiny amounts may remain after filtering.
Possible Contamination During Aging and Storage
Wine can be held in various types of containers during aging and storage, though stainless steel has become one of the most popular (1).
An older, less common practice is to store it in oak barrels and seal the top with a small amount of wheat paste — which contains gluten. Still, the risk of significant contamination from this is low.
For example, when the Gluten Free Watchdog agency measured gluten concentrations in two different wines that had been aged in wheat-paste sealed barrels, they contained less than 10 ppm of gluten — much less than the FDA limit for gluten-free items.
It's now more common to seal the barrels with paraffin wax. However, to be certain what a winery uses for their sealant, contact them.
Wine can be held in various types of containers during aging, though stainless steel is one of the most popular. Less frequently, it's stored in oak barrels sealed with wheat paste, but gluten contamination from this method is usually minimal.
Wine Coolers May Contain Gluten
Wine cooler drinks first gained popularity in the 1980s. In the past, they were made with a small percentage of wine mixed with fruit juice, a carbonated beverage, and sugar. They were generally gluten-free.
However, after a major tax increase on wine in the U.S. in 1991, most wine coolers were reformulated as sweet, fruity malt beverages. Malt is made from barley, a gluten-containing grain (13).
These fruity drinks are labeled malt coolers or malt beverages but could be mistaken for wine coolers. These beverages contain gluten and should be avoided by those with celiac disease or gluten intolerance (14).
Fruity drinks called wine coolers have largely been reformulated as malt coolers made from barley, a gluten-containing grain. You should avoid malt beverages on a gluten-free diet.
Other Reasons You May Feel Unwell
If you avoid gluten and have experienced headaches, digestive upset or other symptoms after drinking wine, reasons other than gluten contamination may be to blame:
- Expanding blood vessels. Drinking alcohol causes blood vessels to expand, which stretches the nerve fibers wrapped around them. When this happens in your brain, it can trigger headaches (15).
- Inflammation. Alcohol may increase gut inflammation, particularly in people with inflammatory bowel diseases (IBD), including Crohn's disease and ulcerative colitis. Some people with celiac disease also have IBD (16, 17, 18).
- Histamine and tyramine. Some people are sensitive to these byproducts of fermentation, which may trigger headaches and digestive upset. Red wine may contain up to 200 times more histamine than white wine (15, 19, 20, 21).
- Tannins. Wine contains certain plant compounds, including tannins and other flavonoids, that may trigger headaches. Red wine typically contains more than 20 times the flavonoids of white wine (15, 22).
- Sulfites. These may be added as a preservative to both red and white wines but must be declared on the label if totaling 10 ppm or more. Sulfites are compounds that can trigger asthma and possibly headaches (1, 22, 23).
- Allergens. Some fining agents come from allergens like milk, eggs, and fish. It's unlikely that enough remains to cause a reaction, but processing varies. Wine labels don't have to disclose allergens like foods do (1, 24, 25, 26).
Wine contains many compounds other than gluten that can trigger headaches and digestive system upset in sensitive individuals.
The Bottom Line
Wine is naturally gluten-free, but some practices — including using gluten during the fining process and aging it in oak barrels sealed with wheat paste — may add tiny amounts of gluten.
If you're sensitive to traces of gluten, ask the winery how their products are made or purchase certified gluten-free varieties.

The patient in the case report (let's call him Tom) was 54 and in good health. For two days in May, he felt unwell and was too weak to get out of bed. When his family finally brought him to the hospital, doctors found that he had a fever and signs of a severe infection, or sepsis. He tested positive for SARS-CoV-2, the virus that causes COVID-19 infection. In addition to symptoms of COVID-19, he was also too weak to move his legs.
When a neurologist examined him, Tom was diagnosed with Guillain-Barre Syndrome, an autoimmune disease that causes abnormal sensation and weakness due to delays in sending signals through the nerves. Usually reversible, in severe cases it can cause prolonged paralysis involving breathing muscles, require ventilator support and sometimes leave permanent neurological deficits. Early recognition by expert neurologists is key to proper treatment.
We are neurologists specializing in intensive care and leading studies related to neurological complications from COVID-19. Given the occurrence of Guillain-Barre Syndrome in prior pandemics with other corona viruses like SARS and MERS, we are investigating a possible link between Guillain-Barre Syndrome and COVID-19 and tracking published reports to see if there is any link between Guillain-Barre Syndrome and COVID-19.
Some patients may not seek timely medical care for neurological symptoms like prolonged headache, vision loss and new muscle weakness due to fear of getting exposed to virus in the emergency setting. People need to know that medical facilities have taken full precautions to protect patients. Seeking timely medical evaluation for neurological symptoms can help treat many of these diseases.
What Is Guillain-Barre Syndrome?
Guillain-Barre syndrome occurs when the body's own immune system attacks and injures the nerves outside of the spinal cord or brain – the peripheral nervous system. Most commonly, the injury involves the protective sheath, or myelin, that wraps nerves and is essential to nerve function.
Without the myelin sheath, signals that go through a nerve are slowed or lost, which causes the nerve to malfunction.
To diagnose Guillain-Barre Syndrome, neurologists perform a detailed neurological exam. Due to the nerve injury, patients often may have loss of reflexes on examination. Doctors often need to perform a lumbar puncture, otherwise known as spinal tap, to sample spinal fluid and look for signs of inflammation and abnormal antibodies.
Studies have shown that giving patients an infusion of antibodies derived from donated blood or plasma exchange – a process that cleans patients' blood of harmful antibodies - can speed up recovery. A very small subset of patients may need these therapies long-term.
The majority of Guillain-Barre Syndrome patients improve within a few weeks and eventually can make a full recovery. However, some patients with Guillain-Barre Syndrome have lingering symptoms including weakness and abnormal sensations in arms and/or legs; rarely patients may be bedridden or disabled long-term.
Guillain-Barre Syndrome and Pandemics
As the COVID-19 pandemic sweeps across the globe, many neurologic specialists have been on the lookout for potentially serious nervous system complications such as Guillain-Barre Syndrome.
Though Guillain-Barre Syndrome is rare, it is well known to emerge following bacterial infections, such as Campylobacter jejuni, a common cause of food poisoning, and a multitude of viral infections including the flu virus, Zika virus and other coronaviruses.
Studies showed an increase in Guillain-Barre Syndrome cases following the 2009 H1N1 flu pandemic, suggesting a possible connection. The presumed cause for this link is that the body's own immune response to fight the infection turns on itself and attacks the peripheral nerves. This is called an "autoimmune" condition. When a pandemic affects as many people as our current COVID-19 crisis, even a rare complication can become a significant public health problem. That is especially true for one that causes neurological dysfunction where the recovery takes a long time and may be incomplete.
Though there is clear clinical suspicion that COVID-19 can lead to Guillain-Barre Syndrome, many important questions remain. What are the chances that someone gets Guillain-Barre Syndrome during or following a COVID-19 infection? Does Guillain-Barre Syndrome happen more often in those who have been infected with COVID-19 compared to other types of infections, such as the flu?
The only way to get answers is through a prospective study where doctors perform systematic surveillance and collect data on a large group of patients. There are ongoing large research consortia hard at work to figure out answers to these questions.
Understanding the Association Between COVID-19 and Guillain-Barre Syndrome
While large research studies are underway, overall it appears that Guillain-Barre Syndrome is a rare but serious phenomenon possibly linked to COVID-19. Given that more than 10.7 million cases have been reported for COVID-19, there have been 10 reported cases of COVID-19 patients with Guillain-Barre Syndrome so far – only two reported cases in the U.S., five in Italy, two cases in Iran and one from Wuhan, China.
It is certainly possible that there are other cases that have not been reported. The Global Consortium Study of Neurological Dysfunctions in COVID-19 is actively underway to find out how often neurological problems like Guillain-Barre Syndrome is seen in hospitalized COVID-19 patients. Also, just because Guillain-Barre Syndrome occurs in a patient diagnosed with COVID-19, that does not imply that it was caused by the virus; this still may be a coincident occurrence. More research is needed to understand how the two events are related.
Due to the pandemic and infection-containment considerations, diagnostic tests, such as a nerve conduction study that used to be routine for patients with suspected Guillain-Barre Syndrome, are more difficult to do. In both U.S. cases, the initial diagnosis and treatment were all based on clinical examination by a neurological experts rather than any tests. Both patients survived but with significant residual weakness at the time these case reports came out, but that is not uncommon for Guillain-Barre Syndrome patients. The road to recovery may sometimes be long, but many patients can make a full recovery with time.
Though the reported cases of Guillain-Barre Syndrome so far all have severe symptoms, this is not uncommon in a pandemic situation where the less sick patients may stay home and not present for medical care for fear of being exposed to the virus. This, plus the limited COVID-19 testing capability across the U.S., may skew our current detection of Guillain-Barre Syndrome cases toward the sicker patients who have to go to a hospital. In general, the majority of Guillain-Barre Syndrome patients do recover, given enough time. We do not yet know whether this is true for COVID-19-related cases at this stage of the pandemic. We and colleagues around the world are working around the clock to find answers to these critical questions.

One of the initial reasons social distancing guidelines were put in place was to allow the healthcare system to adapt to a surge in patients since there was a critical shortage of beds, ventilators and personal protective equipment. In fact, masks that were designed for single-use were reused for an entire week in some hospitals.

Unity Task Forces formed by presumptive Democratic presidential nominee Joe Biden and Sen. Bernie Sanders unveiled sweeping party platform recommendations Wednesday that—while falling short of progressive ambitions in a number of areas, from climate to healthcare—were applauded as important steps toward a bold and just policy agenda that matches the severity of the moment.
"We've moved the needle a lot, especially on environmental justice and upping Biden's ambition," said Sunrise Movement co-founder and executive director Varshini Prakash, a member of the Biden-Sanders Climate Task Force. "But there's still more work to do to push Democrats to act at the scale of the climate crisis."
The climate panel—co-chaired by Rep. Alexandria Ocasio-Cortez (D-N.Y.) and former Secretary of State John Kerry—recommended that the Democratic Party commit to "eliminating carbon pollution from power plants by 2035," massively expanding investments in clean energy sources, and "achieving net-zero greenhouse gas emissions for all new buildings by 2030."
In a series of tweets Wednesday night, Ocasio-Cortez—the lead sponsor of the House Green New Deal resolution—noted that the Climate Task Force "shaved 15 years off Biden's previous target for 100% clean energy."
"Of course, like in any collaborative effort, there are areas of negotiation and compromise," said the New York Democrat. "But I do believe that the Climate Task Force effort meaningfully and substantively improved Biden's positions."
Today the 6 Biden-Sanders Unity Task Forces are unveiling final language. The Climate Task Force accomplished a gr… https://t.co/gz3broq2qe— Alexandria Ocasio-Cortez (@Alexandria Ocasio-Cortez)1594240617.0
The 110 pages of policy recommendations from the six eight-person Unity Task Forces on education, the economy, criminal justice, immigration, climate change, and healthcare are aimed at shaping negotiations over the 2020 Democratic platform at the party's convention next month.
Sanders said that while the "end result isn't what I or my supporters would've written alone, the task forces have created a good policy blueprint that will move this country in a much-needed progressive direction and substantially improve the lives of working families throughout our country."
"I look forward to working with Vice President Biden to help him win this campaign," the Vermont senator added, "and to move this country forward toward economic, racial, social, and environmental justice."
Biden, for his part, applauded the task forces "for helping build a bold, transformative platform for our party and for our country."
"I am deeply grateful to Bernie Sanders for working with us to unite our party and deliver real, lasting change for generations to come," said the former vice president.
On the life-or-death matter of reforming America's dysfunctional private health insurance system—a subject on which Sanders and Biden clashed repeatedly throughout the Democratic primary process—the Unity Task Force affirmed healthcare as "a right" but did not embrace Medicare for All, the signature policy plank of the Vermont senator's presidential bid.
Instead, the panel recommended building on the Affordable Care Act by establishing a public option, investing in community health centers, and lowering prescription drug costs by allowing the federal government to negotiate prices. The task force also endorsed making all Covid-19 testing, treatments, and potential vaccines free and expanding Medicaid for the duration of the pandemic.
"It has always been a crisis that tens of millions of Americans have no or inadequate health insurance—but in a pandemic, it's potentially catastrophic for public health," the task force wrote.
Dr. Abdul El-Sayed, a former Michigan gubernatorial candidate and Sanders-appointed member of the Healthcare Task Force, said that despite major disagreements, the panel "came to recommendations that will yield one of the most progressive Democratic campaign platforms in history—though we have further yet to go."
We rein in #pharma's greed by: 1) Allowing Medicare to FINALLY negotiate Rx drugs FOR ALL AMERICANS 2) Using Rx d… https://t.co/6k9iUCLMp7— Abdul El-Sayed (@Abdul El-Sayed)1594238411.0
Observers and advocacy groups also applauded the Unity Task Forces for recommending the creation of a postal banking system, endorsing a ban on for-profit charter schools, ending the use of private prisons, and imposing a 100-day moratorium on deportations "while conducting a full-scale study on current practices to develop recommendations for transforming enforcement policies and practices at ICE and CBP."
Marisa Franco, director of immigrant rights group Mijente, said in a statement that "going into these task force negotiations, we knew we were going to have to push Biden past his comfort zone, both to reconcile with past offenses and to carve a new path forward."
"That is exactly what we did, unapologetically," said Franco, a member of the Immigration Task Force. "For years, Mijente, along with the broader immigrant rights movement, has fought to reshape the narrative around immigration towards racial justice and to focus these very demands. We expect Biden and the Democratic Party to implement them in their entirety."
"There is no going back," Franco added. "Not an inch, not a step. We must only move forward from here."
