The Corks in My Drawer
What it takes to give up a belief you enjoyed holding.
I keep the corks. Douro, Montalcino, Etna, a dozen others in a kitchen drawer with the twine and the batteries. My wife thinks the drawer is ridiculous. The drawer is a record of about fifteen years of choosing where to go based on what grows there.
I’m also a physician who studies substance use, which means I spent those same fifteen years reading the alcohol literature. I watched the heart-healthy wine story fall apart in slow motion, and I kept buying wine the entire time. The interesting part is not the science. The interesting part is the lag.
The story I inherited
In 1992, two French researchers published a paper in The Lancet naming the French Paradox: relatively low coronary disease in a country eating plenty of saturated fat. They pointed at wine. Morley Safer had already carried the idea into American living rooms on 60 Minutes in November 1991, and red wine sales in the US rose 39 percent the following year. If you were an adult in the 1990s, you absorbed this whether or not you ever read a study.
The mechanism arrived next. Resveratrol, a compound in grape skins, got credited with the effect and became one of the most studied molecules in nutrition. The arithmetic never worked. A glass of red delivers under two milligrams of resveratrol. Trials showing any effect used 100 to 500 milligrams a day. One dose-response analysis calculated you’d need roughly 111 glasses daily to reach the level studied for cancer prevention.
The founding laboratory result also came apart. In 2005, researchers showed resveratrol’s apparent activation of the longevity enzyme SIRT1 depended on a fluorescent tag attached to the test molecule. Use the natural substrate and the effect disappears. A 2025 review of eleven randomized trials found no change in human SIRT1 after supplementation at all. And one of the most prolific authors on resveratrol and heart protection, at the University of Connecticut, was found by investigators to have fabricated and falsified data across numerous papers, which triggered a wave of retractions.
Then the epidemiology went. The wine was never the problem. The comparison group was. A German cohort found 90.6 percent of people counted as abstainers were former drinkers, many of whom had quit because they were already sick. Line those people up against healthy moderate drinkers and wine looks protective without wine doing anything. When one team reanalyzed 87 studies correcting for this, the mortality benefit slid from a relative risk of 0.86 to 0.97, which is another way of saying the benefit vanished.
Why the belief held on
I knew about the sick-quitter critique years before I changed anything about how I talked or drank. Four things kept the belief alive in me.
The claim granted permission. Nearly all health advice asks you to give something up. This one handed something back. We scrutinize findings that demand sacrifice and wave through findings that license what we already do, and the asymmetry runs below conscious reasoning. I can tell you exactly which alcohol papers I read closely and which I skimmed, and the pattern is not flattering.
The belief was attached to identity. Wine, for me, means travel and long dinners and knowing why Etna tastes like ash. Question the health claim and you brush against a self-concept. People defend identity-linked beliefs more stubbornly than ordinary ones and experience corrections as personal insult.
The story had machinery inside. A molecule, an enzyme, a pathway. A causal story feels more true than a bare correlation, even when the machinery explains nothing. Resveratrol made the French Paradox feel mechanistic rather than anecdotal, and the feeling survived long after the mechanism died.
And the belief had social confirmation everywhere. Sommeliers repeated the claim. Physicians repeated the claim. My own father repeated the claim while pouring. Repetition by trusted people produces the same subjective certainty as evidence does, and the two are indistinguishable from the inside.
The country moved before I did
Gallup has asked Americans since 2001 whether moderate drinking harms health. In 2001, 27 percent said yes. In 2026, half do. That shift is one of the larger reversals in public health opinion in my lifetime, and most of the movement happened in the last four years.
Young adults got there first. Half of Americans aged 18 to 35 reported drinking in Gallup’s 2025 survey, down from 59 percent in 2023. They came up after the 60 Minutes era and never received the permission the rest of us absorbed, which turns out to be an advantage. Nothing to unlearn.
What stays genuinely open
Wine drunk slowly, with food, spread across a week, might carry a small real benefit. A July 2026 analysis of two Spanish cohorts found lower mortality with moderate wine inside a Mediterranean diet, and the authors flagged that their analyses least vulnerable to the abstainer problem missed statistical significance. A Spanish trial is now randomizing 10,000 drinkers aged 50 to 75 to abstain or continue, the first real experiment in a field built almost entirely on observation. I’m not holding my breath, and I’m not pretending the question is closed either.
What changed for me
I still drink wine. I stopped calling wine healthy, out loud and in my head. The distinction does real work, because “heart-healthy” was an argument for the second glass and “I enjoy this” makes no argument at all. The second glass now has to justify itself on its own terms, and sometimes the second glass doesn’t.
If you want the transferable version: notice which studies you read carefully. Notice which ones you accept in a sentence. The gap between those two habits is where a comfortable belief hides, and the gap is invisible from the inside unless you go looking for it deliberately.
The drawer is still full. I added one in June.
