Featured on Gordon Ramsay’s Food Stars

Judges tested BOĆE side-by-side and observed a noticeable difference.

What Happened In Peri's Pitch

When BOĆE appeared on Gordon Ramsay’s Food Stars, the judges were openly skeptical, much like many first-time customers encountering the idea for the first time. Rather than relying on explanations or claims, BOĆE was tested the same way people use it at home: by comparing the same drink side-by-side.

After placing one glass on the coaster and tasting again a few minutes later, the judges noticed a clear difference in flavor. The drink tasted smoother and more balanced, without anything added, filtered, or changed in the glass itself.

That moment of quiet surprise mirrored what many customers describe — not a dramatic transformation, but a noticeable improvement that’s easiest to appreciate when you try it for yourself.

International patented drink enhancement technology

Works with any beverage, hot or cold, in any type of container.

Independently lab tested to improve beverage taste

Backed by Independent Testing

What was tested, what changed, and what it means for taste.

You don’t need to understand the science to enjoy the result.

Why Drinks Can Taste Harsh

A sharp wine, burning whiskey, or bitter coffee isn’t poor craftsmanship.

These harsh notes are often caused by naturally occurring compounds created during fermentation, distillation, and oxidation. Over time, they can dull aroma, add bite, and leave a rough finish on the palate.

What Independent Labs Observed

  • Measurable reductions in compounds commonly associated with harshness
  • Changes detected after as little as 5 minutes
  • Results aligned with how customers describe smoother taste

What This Means When You Take a Sip

When these harsh compounds are reduced, drinks tend to taste smoother, cleaner, and more balanced.

Many people describe less burn in spirits, softer edges in wine, and reduced bitterness in coffee — without anything being added to the drink itself.

Frequently asked questions

Does BOĆE really work, or is it just a placebo?

BOĆE Coasters are backed by over 30 years of research from Dr. Drew Karp and independently tested by AAR Labs. Lab results show up to a 40% reduction in fusel alcohols — the compounds that cause burn, bitterness, and harsh aftertastes. The difference is noticeable in blind taste tests, which is why thousands of customers trust BOĆE to elevate their daily drinks.

What makes BOĆE different from other drink gadgets or filters?

Unlike chemical additives, drops, or aerators, BOĆE uses patented quantum light technology that never comes into direct contact with your beverage. There’s nothing to add, nothing to replace, and nothing that alters alcohol content. The result is smoother, cleaner taste with zero compromise — and the coaster itself is infinitely reusable.

Will it work for me even if I usually don’t notice subtle flavor changes?

Yes. Many customers report that BOĆE makes harsh spirits easier to sip, takes the edge off black coffee, and makes budget wine taste like a higher-priced bottle. Even if you don’t consider yourself a “super taster,” the difference is often obvious in side-by-side comparisons. That’s why we encourage the “BOĆE Challenge” — taste a drink with and without the coaster, and let your palate decide.

How do I know it’s safe to use?

BOĆE Coasters are made from 100% food-safe, dishwasher-safe acrylic and use light-based frequencies only. There are no chemicals, additives, or moving parts, and nothing enters your beverage. The technology is designed to be safe, clean, and durable for a lifetime of use.

What if I’m not satisfied with the results?

We stand behind BOĆE with a 30-day money-back guarantee. If you don’t notice a difference in your drinks, simply return it with no questions asked. Thousands of customers have made BOĆE part of their daily routine, but we want you to feel confident trying it risk-free.
