Riedel Restaurant Drink Specific Double Rocks Tumbler
The Riedel Restaurant Bar Drink Specific Double Rocks Tumbler (0417/07) was added to the Drink Specific collection in 2022, answering a specific demand from bars and restaurants: a larger rocks format designed to handle a double measure, large-format ice, and the full build of a serious spirit-forward cocktail in a single, well-proportioned glass. At 370ml with an 83mm opening and a low, stable 102mm profile, it provides everything the Old Fashioned, Negroni, Boulevardier, and their contemporary variations require, without the glass looking sparse at a 60ml pour.
The design's standout feature is the oar: a thicker section moulded into the lower portion of the glass wall. Pouring spirit to the top of this oar shape delivers exactly 60ml, a standard double measure, with no jigger needed. For a bartender building an Old Fashioned directly in the glass, the oar line means the base spirit is always consistent, the build process loses a step, and the drink never looks under-poured when the ice goes in. It is an elegant, practical solution to one of the most common customer perception problems in cocktail service: the sense, created by large ice displacing liquid, that too little has been poured. The glass is part of the Riedel Drink Specific collection, developed in collaboration with mixologist Zane Harris, known for his work at Dutch Kills, Maison Premiere, and Rob Roy, and based on the traditional serves for 7 cocktail classics: the Old Fashioned, Manhattan, Daiquiri, Sour, Peasant, Buck, and Julep. Machine-made in lead-free crystal and certified for 1,500 commercial dishwasher cycles, it is sold in sets of 12 for professional bar and restaurant use.
Key features of the Riedel Drink Specific Double Rocks Tumbler:
- Built for large-format ice: Designed specifically to accommodate large ice cubes and spheres, the increasingly standard ice format at serious cocktail bars, allowing both to sit correctly in the glass without forcing the build into an awkward proportion
- Integrated 60ml oar fill line: The thicker oar design near the base of the glass marks an exact 60ml double measure. Pouring to the top of the oar delivers the correct spirit volume without a jigger, streamlining the build and eliminating the visual impression of an under-poured drink when large ice is added
- 370ml double-measure capacity: More volume than the standard Drink Specific Rocks glass, providing room for a double spirit, modifiers, large ice, and a garnish in a correctly proportioned glass
- Zane Harris collaboration: Part of the Drink Specific Glassware collection developed with spirits specialist Zane Harris, applying the same design rigour to cocktail glasses that Riedel has applied to wine glasses for decades
- Covers the Old Fashioned family and beyond: The correct glass for Old Fashioned, Negroni, Boulevardier, Mezcal Negroni, Paper Plane, Jungle Bird, Mai Tai, and any spirit-forward cocktail built or served over large ice
- Lead-free crystal construction: Machine-made with clarity and weight consistent with Riedel's premium barware standard
- 1,500-cycle dishwasher certification: EN 12875-1/2 certified, suited to the demands of high-volume bar service
- Set of 12, trade-only: Bar-format case quantity for professional operations, available exclusively to trade
This glass is the natural choice for any bar or restaurant with a serious cocktail programme, particularly those with an established large-format ice operation. It works within the Drink Specific range alongside the standard Rocks, Highball, Nick and Nora, Sour, and Fizz glasses, covering the full canon of classic and contemporary cocktail service from a single coherent collection.
What Bar and Restaurant Professionals Ask About This Glass
How does the oar fill line actually work in service?
The oar is a thicker section of glass moulded into the lower part of the wall. It creates a visible and tactile reference point that a bartender can see and feel during a build. Pouring spirit until it reaches the top of the oar delivers 60ml without measuring separately. For a busy bar building ten Old Fashioneds during a service rush, removing the jigger step from the base spirit pour is a meaningful efficiency gain. The precision is also consistent glass to glass across the entire set of 12, so the measure is reliable regardless of which glass in the set is being used.
Why does ice displacement matter and how does this glass address it?
When a large ice cube is placed in a glass after the spirit has been poured, it displaces liquid upward and makes the drink appear fuller than it was. Conversely, when a large ice block is placed in an undersized glass first and the spirit poured over it, the liquid level can look low even at the correct measure, creating a customer perception of being under-served. The Double Rocks addresses this at the design stage: its 370ml capacity is calibrated so that a 60ml spirit pour to the oar line, plus the volume of a large ice block and any modifiers, produces a drink that looks correctly and generously filled. The oar line establishes the spirit measure before ice goes in, so the bartender and the customer both have a consistent reference point.
Do we need both the standard Rocks Glass and the Double Rocks?
That depends on how your cocktail menu is structured. The standard Rocks glass (283ml) is designed for single builds and short doubles in a compact format that fits comfortably in one hand. The Double Rocks (370ml) is the right choice when the build requires more volume: a double measure of spirit, significant modifiers, and large ice together. If your Old Fashioned is a serious, specified-spirit double at 60ml with a large cube, the Double Rocks is the correct glass and the standard Rocks will look cramped. If you also serve compact, lower-spirit builds over smaller ice, stocking both shapes makes sense. Many cocktail programmes use the Double Rocks as their primary rocks format and reserve the standard Rocks for specific shorter builds.
What is the Drink Specific collection and who is Zane Harris?
The Riedel Drink Specific Glassware collection was developed in collaboration with Zane Harris, a US spirits specialist and mixologist who has worked at some of North America's most respected cocktail bars: Dutch Kills in New York, Maison Premiere in Brooklyn, and Rob Roy in Seattle. Harris approached Riedel with the argument that cocktails deserved the same glass-design precision that wine had received for decades, with specific attention to size, shape, volume, and ice capacity. The collection launched in 2018 with six shapes and expanded with the Double Rocks in 2022. Each glass is based on the traditional serves for 7 cocktail classics: the Old Fashioned, Manhattan, Daiquiri, Sour, Peasant, Buck, and Julep, covering thousands of cocktails across those seven families.
How many dishwasher cycles are these glasses certified for?
The Drink Specific Double Rocks Tumbler is certified to EN 12875-1/2 standards for 1,500 commercial dishwasher cycles with no visible deterioration, corresponding to 10+ years of normal bar or restaurant service life.
The Large Ice Problem: Why the Double Rocks Exists
Large-format ice has moved from novelty to standard in serious cocktail bars over the past decade. The reasons are well understood: a single large cube or sphere melts more slowly than a glass full of smaller cubes, dilutes the drink more predictably, and looks significantly more considered than a handful of crushed ice or commercial cubes. For an Old Fashioned or a Negroni, large ice is no longer a premium differentiator — it is an expectation in any bar that takes its cocktail programme seriously.
The problem that large ice creates for glassware is one of proportion and perception. A standard rocks glass sized for small ice looks cramped with a large cube and risks looking under-poured even when the measure is correct. The alternative, an oversized glass with too much empty space around the ice, looks equally wrong. The Double Rocks was designed to solve this specific problem: it is sized so that a 60ml double measure, a large cube, and any modifiers and garnish fill the glass to a proportion that reads as generous and considered.
The oar fill line is the operational completion of that design logic. Zane Harris's insight that ice displacement creates one of bar service's most common customer dissatisfaction moments — the perception of being under-poured — is addressed not just by the glass dimensions but by building the measure directly into the glass. The bartender pours to the oar. The ice goes in. The drink looks correct. The customer perceives a well-made, generously served cocktail. That chain of design decisions from fill line to glass volume to ice accommodation represents exactly the kind of holistic thinking that the Drink Specific collection was built around.
For operations that want their cocktail programme to communicate the same level of consideration that a varietal wine glass communicates for a wine list, the Drink Specific range, and the Double Rocks specifically, is the clearest available statement of intent.
Specifications
Care & Use Instructions
Commercial Dishwasher Use: Certified for 1,500 commercial dishwasher cycles under EN 12875-1/2. The 83mm diameter and 102mm height make this one of the most compact and stable glasses in the Drink Specific range in the dishwasher rack. Use standard commercial cycles with professional-grade detergent. Remove promptly and allow to air dry. The oar section at the base can collect water; ensure glasses are fully dry before service to avoid dilution of the first pour.
Building a Drink in the Glass: For Old Fashioned and similar built cocktails, the standard sequence is spirit to the oar mark (60ml), sugar and bitters as required, then ice. Add the large cube after the liquid components so that ice displacement brings the drink to the correct final level. For stirred cocktails such as a Negroni intended to be served in the glass, stir over ice in a separate mixing glass and strain over a fresh large cube in the Double Rocks.
Ice Guidance: The 83mm diameter accommodates standard 5x5cm large cubes and most commercially produced 6cm cubes. Spheres of 5-6cm diameter fit correctly. Ice should be placed in the glass smoothly rather than dropped to avoid glass stress. Temper the glass if ice is being used directly from a freezer below -15°C by briefly rinsing with cold water before service.
Handling: The low, wide profile of the Double Rocks makes it one of the most stable glasses in bar service. Hold from the lower portion of the bowl. The compact 102mm height means it carries well on a tray even in sets of several glasses.
Storage: The compact dimensions make the Double Rocks highly space-efficient in storage and on the back bar. Store upright. The 83mm base fits standard commercial glass racks; the low profile means multiple rows can be stored in a standard-height rack shelf.
