Wine Myth or Fact? The Ultimate Wine Knowledge Quiz

Wine is one of the most myth-laden beverages on earth. Over decades of winemaking and wine writing, Jesse and I have heard almost every misconception there is — from sulfites causing headaches to screw caps meaning cheap wine to red wine needing to breathe for an hour before you serve it. Some of these myths have a kernel of truth. Most don’t.

This quiz is different from our WSET practice series — it’s designed not to test your exam knowledge, but to challenge your wine intuitions. Each question presents a common wine belief and asks you whether it’s a myth or a fact backed by science, winemaking practice, or solid research.

You might be surprised by how many popular wine beliefs don’t hold up under scrutiny. Whether you’re a casual wine drinker who wants to drink smarter, a hospitality professional who wants to stop passing on bad advice, or a WSET student looking for a fun break from flashcards, this quiz will give you something to think about.

BONUS: WINE MYTH OR FACT?

A fun wine knowledge quiz to test your expertise. Not affiliated with WSET.

"Red wine should be served at room temperature." Myth or Fact? Myth — "Room temperature" was defined centuries ago when rooms were 15-18°C. Modern room temperature (22-24°C) is too warm for red wine. Fact — all red wines should be served at the temperature of a modern heated room. Myth — red wine should always be chilled like white wine. Fact — but only for full-bodied reds.

"Screw caps are a sign of cheap wine." Myth or Fact? Fact — premium wines always use cork. Myth — many premium producers worldwide use screw caps, especially for wines meant to be consumed young and fresh. Myth — screw caps are actually better than cork in every situation. Fact — screw caps don't allow any aging.

"Legs (tears) on the side of a glass indicate a better quality wine." Myth or Fact? Fact — more legs mean higher quality. Myth — legs are caused by alcohol and glycerol content (the Marangoni effect), not by quality. Myth — legs indicate the wine is spoiled. Fact — but only for red wines.

"Sulfites in wine cause headaches." Myth or Fact? Fact — sulfites are the primary cause of wine headaches. Myth — most wine headaches are caused by histamines, tannins, or simply drinking too much. Dried fruit has more sulfites than most wines. Myth — wine contains no sulfites. Fact — but only in red wine.

"You should let wine 'breathe' by opening the bottle." Myth or Fact? Fact — opening the bottle provides all the aeration wine needs. Myth — the small opening of a bottle neck exposes almost no wine to air. Decanting or pouring into a glass is far more effective. Myth — wine should never be exposed to air. Fact — but only for 30 minutes.

"Champagne should be opened with a loud pop." Myth or Fact? Fact — the pop means the wine is properly carbonated. Myth — a gentle hiss is the correct way to open Champagne. A loud pop wastes pressure and can spray wine. Myth — Champagne bottles don't actually pop. Fact — but only for celebrations.

"Wine always gets better with age." Myth or Fact? Fact — all wines improve with aging. Myth — the vast majority of wine (over 90%) is meant to be consumed within a few years of release. Myth — wine never improves with age. Fact — but only for reds.

"White wine with fish, red wine with meat." Myth or Fact? Fact — this rule should always be followed. Myth — while it's a useful starting point, many exceptions exist. A light Pinot Noir pairs beautifully with salmon; a rich Chardonnay works with chicken. Myth — the opposite is actually true. Fact — it applies to all fish and all meat.

"Expensive wine tastes better." Myth or Fact? Fact — price directly correlates with quality. Myth — price reflects production costs, rarity, and brand prestige. Blind tastings consistently show that even experts can't reliably rank wines by price. Myth — cheap wine is always better value. Fact — but only above $50.

"You can tell a wine's quality by the weight of the bottle." Myth or Fact? Fact — heavier bottles contain better wine. Myth — heavy bottles are a marketing choice, not a quality indicator. They increase shipping costs and environmental impact. Myth — lighter bottles are actually premium. Fact — heavy glass protects wine from light damage.

The Biggest Wine Myths — Busted

Here are a few of the most persistent wine myths we encounter, along with what the evidence actually says:

Myth: Sulfites cause red wine headaches. The evidence doesn’t support this. Dried apricots contain more sulfites than most wines. The more likely culprits are histamines, tannins, or simply alcohol — and drinking a big tannic red on an empty stomach while dehydrated. Most people who think they have a sulfite sensitivity don’t.

Myth: Screw caps mean the wine is cheap. This was true in the 1970s. It’s not true now. New Zealand Sauvignon Blanc and many of the finest wines from Australia, Austria, and Germany are sealed with screw caps because they’re better for preserving delicate aromatics. Top producers worldwide have made the switch.

Myth: Red wine should breathe for an hour before drinking. Pouring it into the glass and waiting ten minutes does most of the work. If a wine genuinely needs extended air exposure, decanting is far more effective than removing the cork and leaving the bottle on the counter.
