Built For Real Life: Tritan is genuinely shatter-resistant, which is the whole point of the Resort collection, but it's still worth treating it as you would any decent tumbler rather than kitchen plasticware. Avoid abrasive scourers or scouring powders, which can dull the clear finish over time, and steer clear of extreme heat (an oven, a hob, or boiling water poured directly in). Used sensibly, that's the only care it asks for: no delicate handling, no special drying ritual, just a glass that's happy to live outdoors.

What Customers Ask About RIEDEL Resort Double Rocks

Tritan™ from Eastman is a copolyester material engineered to be crystal-clear and shatter-resistant. Unlike lead-free crystal, it won't chip or shatter if knocked against a hard surface, which is why RIEDEL uses it for the Resort collection rather than the crystal it uses elsewhere. It doesn't have quite the same brilliance or weight as crystal in the hand, but it's close enough visually that most people won't clock the difference from across a table, and the durability trade-off is the entire reason this collection exists.

It's a subtle line built into the glass at the 60ml (2oz) mark, giving you a consistent reference point for a standard spirit measure without needing a separate jigger. It's useful for building an Old Fashioned or a simple spirit serve accurately, and just as useful behind a home bar as it is in a professional setting where consistent pours matter.

Yes. The solid, stable base is designed to support muddling herbs, fruit or sugar directly in the glass, which is standard practice for cocktails like an Old Fashioned or a Caipirinha-style short drink. The wide opening also gives a muddler room to work without splashing.

That's what the Resort collection is built for. Tritan's shatter resistance makes it a sensible choice anywhere traditional glassware carries too much risk: poolside, on a terrace, on a boat, or in a spa setting where broken glass is a genuine hazard. It keeps the clarity and proportions of proper glassware without that risk.

Yes, deliberately so. The wide opening and generous 411ml capacity are sized to comfortably fit large-format ice cubes or spheres, which melt more slowly than smaller cubes. That means your drink chills and dilutes gradually rather than flooding with meltwater in the first few minutes, which matters for a spirit-forward serve where you want the flavour to hold up.

From Drink Specific Glassware to Resort

Riedel's Drink Specific Glassware series, developed with bartender Zane Harris, started from a simple premise: that most cocktail glassware is generic, when the drinks it serves are not. Harris, known for his bartending work at venues including Dutch Kills, Maison Premiere and Rob Roy, worked with Riedel to design six shapes around how classic cocktails are actually built and served, with ice as the starting point for each design decision.

The Double Rocks glass was one of those shapes, sized and proportioned for spirits and short cocktails served over substantial ice. RIEDEL Resort takes that proven shape and reproduces it in Tritan rather than crystal, extending the same design thinking to settings where crystal glassware simply isn't practical. The proportions, the drink marker and the wide opening are unchanged. What's different is the material underneath them.

That distinction matters if you already own the crystal Drink Specific Glassware Double Rocks: this isn't a replacement for it, but a companion for situations where you wouldn't want to risk the crystal version in the first place.

Why Shape Matters for Spirits and Cocktails Over Ice

A rocks glass has a straightforward job: hold a spirit or short cocktail, accommodate ice without the drink flooding with meltwater too quickly, and stay stable if the drink is built or muddled in the glass itself. Get the proportions wrong and any of those can fail - too narrow, and there's no room for a proper ice cube; too shallow, and the drink warms and dilutes faster than intended; too light a base, and muddling becomes a hazard rather than a technique.

The Double Rocks shape addresses all three directly. The 411ml capacity and wide 83mm opening give large ice cubes room to sit without crowding the spirit, which slows dilution and keeps the drink cold for longer. The solid base provides the stability needed to muddle fruit, herbs or sugar without the glass tipping or sliding. The integrated drink marker means the measure is consistent whether you're behind a home bar or serving a group.

None of that changes when the material changes from crystal to Tritan. The shape does the work regardless of what it's made from, which is why RIEDEL Resort could carry the Drink Specific Glassware proportions across into a material built for durability rather than starting from scratch.

Care & Use Instructions

Dishwasher Care: The Resort Double Rocks tumbler is dishwasher safe, which is one of the main reasons it suits busy outdoor entertaining. As with any glassware, check placement in the dishwasher so pieces don't knock against other items or the spray arm during the cycle. A normal cycle is fine; there's no need for the delicate handling crystal stemware requires.

Handwashing: Warm water with mild washing-up liquid and a soft cloth or sponge is all this tumbler needs. Avoid abrasive scourers, scouring powders or harsh chemical cleaners, which can scratch or dull Tritan's clear finish over time even though they won't break it. Rinse and dry with a normal tea towel or leave to air dry.

Heat: Tritan is not designed for direct high heat. Keep it away from the oven, hob, or boiling water poured straight in, and don't leave it in direct contact with a hot surface. Normal outdoor sun exposure and dishwasher cycles are well within what it's built for.

Storage: The Resort collection's tumbler shapes are designed to stack, so they store compactly in a cupboard or bar area without needing the vertical space crystal stemware demands. Make sure pieces are dry before stacking to avoid any moisture being trapped between them.

Use with Ice and Muddling: The wide opening and solid base are built for exactly the use this glass is intended for - large ice cubes, muddled fruit or herbs, and a proper spirit measure. There's no special care needed here beyond common sense: a muddler used with reasonable force is fine, but there's no need to lean on it as though the glass were fragile.

It's genuinely crystal-clear rather than the cloudy or slightly tinted look you get from most plastic drinkware, which is why RIEDEL chose it for the Resort collection instead of a cheaper alternative. It doesn't carry quite the same brilliance or weight as lead-free crystal in the hand, but at a glance on a table or poolside it reads as proper glassware.

The Resort Double Rocks tumblers come in RIEDEL's branded gift box, suitable for gifting as they are. They make a practical present for anyone with a pool, a boat, or a garden bar who wants proper cocktail glassware without the breakage risk.

Yes, RIEDEL Resort is part of Riedel's ongoing range. Machine production ensures new tumblers will match your existing pair in size and shape, so you can build up a set for larger gatherings.

The shape and proportions are the same, since RIEDEL Resort is built on the original Zane Harris-designed Double Rocks shape. The difference is entirely material: the original Drink Specific Glassware version is crystal, with the brilliance and weight that implies but also the breakage risk; the Resort version is Tritan, near enough as clear but genuinely shatter-resistant. Choose crystal for the dining table or a formal bar, and Resort for anywhere that risk isn't worth taking - poolside, outdoors, or on a boat.

A generic rocks glass is sized by convention rather than by design. The Double Rocks shape was built specifically around how large-format ice behaves, how much room a spirit or short cocktail needs to be built and muddled in the glass, and where a drink marker is genuinely useful rather than decorative. Those choices carry over from the original Drink Specific Glassware design, which is the part a generic tumbler doesn't replicate even if it looks similar.

With normal use and dishwasher cycles, no. Like any clear material, repeated contact with abrasive scourers, scouring powder or very harsh detergents can eventually dull the surface, so a soft cloth or sponge is the sensible choice for handwashing. Treated reasonably, it holds its clarity well.

RIEDEL typically packages its tumblers in pairs to ensure consistent quality and matching, and presents them together in a single gift box. A pair covers a couple for everyday use or gifting, and you can buy multiple pairs if you need more for entertaining.

The Design Thinking Behind Drink Specific Glassware

Zane Harris's starting point for the Drink Specific Glassware series was that ice, not the spirit itself, has the greatest influence on how a glass should be shaped, since it's present in nearly every classic cocktail and spirit serve. That's a different design brief from wine glassware, where aromatics and swirl room drive the shape. For a rocks glass, the questions are how much ice it needs to hold, how the drinker's hand interacts with the bowl, and how stable the glass is for muddling or stirring.

The Double Rocks shape answers those questions with a wide 83mm opening that fits large-format ice comfortably, a 411ml capacity that leaves room for the ice plus mixers or garnish without crowding, and a solid base built to take the pressure of muddling. The integrated 60ml drink marker adds a practical reference point that a plain tumbler doesn't offer.

RIEDEL Resort carries that same thinking into Tritan, proving the design works independently of the material it's made from. Whether you're building an Old Fashioned at a proper bar or by a pool, the same proportions do the same job - it's just the risk of breakage that changes.
