Copa Glass
The large-bowled stemmed glass the Spanish serve gin and tonic in, holding 600 to 700ml. It looks like an oversized wine glass because that is essentially what it is, and the shape does real work.
Alternatives
Budget Alternative
Large stemmed wine glasses (£4–6): workable, but lack the volume and balance of a true Copa.
Premium Option
Riedel Gin Set or Spiegelau Gin & Tonic Glass (£40–50 per pair): optimised bowl geometry, excellent balance, professional clarity.
Care & Maintenance
Care Instructions
- Hand wash or gentle glassware cycle only
- Dry immediately with a lint-free cloth
- Polish before service to remove water spots
- Store stem-up with adequate spacing
- Inspect stems regularly: size increases leverage and break risk
Expected Lifespan
- •Premium glass: 4–6 years with careful handling
- •Standard glass: 2–3 years in professional service
- •Budget glass: 12–18 months before stem or rim damage
Usage
Gin and tonic built Spanish style: a large bowl packed with cubed ice, a generous measure, tonic poured down a bar spoon and botanical garnish sitting in the headroom. Also spritzes and any long, aromatic, ice-heavy drink.
Copa de Balón
The full name is copa de balón, meaning balloon glass, and it came out of the Basque Country, where bartenders started serving gin and tonic in stemmed wine glasses in the early 2000s.
The style spread across Spain within a decade and became a national ritual: a huge bowl, a great deal of ice, a named gin chosen for its botanicals, and a garnish selected to match rather than a wedge of whatever lime was open.
It reached the UK around 2010 and is now the default in most decent bars, which is a rare case of a glassware change that improved the drink rather than the presentation.
Why the Bowl Helps
Three mechanisms, all of them real.
It holds more ice. A 650ml bowl takes a full load of cubes, and a large mass of ice melts far more slowly than a few cubes in a highball, so the drink dilutes less over twenty minutes rather than more, which is the opposite of what people assume from the size.
It gathers aroma. Gin is a botanical spirit and most of what you taste arrives through the nose; a wide bowl narrowing toward the rim concentrates juniper, citrus and whatever garnish is in there, exactly as it would concentrate a wine's.
And the stem keeps a hand off a drink that lives or dies on temperature.
Building One Properly
Chill the glass, then fill it to the top with cubed ice, not crushed, which dilutes too fast. Stir the ice briefly and pour off any meltwater.
Add 50ml of gin over the ice and stir once. Then pour the tonic slowly down the back of a bar spoon held against the ice, which breaks the fall and keeps most of the carbonation in the glass rather than in the air above it.
Garnish last, and choose for aroma: grapefruit peel and pink peppercorn with a citrus-forward gin, rosemary and lemon with something piney. The garnish sits in the headroom directly under the nose, which is the whole reason to bother.
Size and Buying
Between 600 and 700ml. Smaller than that and it is a wine glass; much larger and the drink looks lost in it and the glass becomes unwieldy.
Look for a wide bowl that tapers noticeably toward the rim, since a straight-sided balloon gathers nothing. A short, thick stem is better than a long delicate one, since these get carried full of ice and are heavy.
Plain glass, unetched and reasonably thin at the lip. They stack badly and the bowl is fragile in a crowded cupboard, so give them their own space rather than nesting them.
Pro Tip
For a balanced Gin & Tonic in a Copa, fill the glass completely with large ice cubes, add gin first, then tonic down a bar spoon. The full ice load keeps dilution in check while the wide bowl releases aroma with every sip.
What to Look For
- Generous bowl size: ice space is the function
- Thin, smooth rim: essential for comfortable sipping
- Long, balanced stem: prevents hand warmth
- Clear, distortion-free glass: visual appeal matters here
- Durable construction: these glasses are often overfilled
Common Mistakes to Avoid
- Under-icing: leads to fast dilution and flat flavours
- Over-garnishing: aromas become muddled
- Using small cubes: they melt too quickly in large bowls
- Over-stirring: kills freshness and lift
- Treating as a wine glass: the function is different
Professional Tips
- Fill it with ice completely. A half-load melts twice as fast.
- Pour the tonic down a bar spoon to keep the bubbles.
- Garnish for smell, not decoration. It sits under your nose.
- Hold the stem. The whole point is that it stays cold.

History & Context
The Copa glass originates from Spanish gin culture, where bartenders sought a vessel large enough to hold significant ice, botanicals, and citrus without overwhelming the spirit. The balloon shape allowed aromas to bloom while keeping drinks cold and visually impressive. As gin and tonic culture spread globally, the Copa became a symbol of modern, garnish-forward service. While often criticised for excess, when used properly it excels at presenting aromatic spirits in long, ice-heavy serves that evolve slowly over time.
Common Questions
What is a copa glass?
A large stemmed balloon glass of 600 to 700ml, the copa de balón, used across Spain for gin and tonic. It came out of the Basque Country in the early 2000s and reached the UK around 2010, where it is now standard in most decent bars.
Why do Spanish bars serve gin and tonic in balloon glasses?
Because the shape does three things: it holds a full load of ice, which dilutes more slowly than a few cubes; it gathers botanical aroma the way a wine glass does; and the stem keeps a warm hand off a drink built on being cold.
Does a copa actually make a gin and tonic better?
Yes, and measurably. More ice means less dilution over twenty minutes, and the tapering bowl concentrates juniper, citrus and garnish under the nose. Most of what you taste in a botanical spirit arrives through smell.
What size is a copa glass?
Between 600 and 700ml. Below that it is really a wine glass, and much above it the drink looks lost and the glass becomes awkward to carry with a full load of ice in it.
