Lewis Bag & Mallet
A canvas bag and wooden mallet for making crushed ice. Essential for Mint Juleps, Swizzles, and Tiki cocktails that require snow-cone consistency.

How to use
- Fill the bag and close it tightly Place the desired amount of ice cubes (standard cubes or half-cubes) into the Lewis bag and fold or close the bag opening tightly. A linen Lewis bag should be damp but not soaking — brief wetting before use prevents the bag from absorbing too much liquid from the ice.
- Strike firmly and evenly Lay the filled Lewis bag on a sturdy, flat surface (a bar mat or heavy cutting board). Strike the bag firmly and evenly with the flat face of the mallet, working across the bag in overlapping strikes to break down all ice pieces uniformly. Ten to fifteen firm strikes produces the snow-cone consistency required for Juleps and Swizzles.
- Check consistency before using Open the bag and check that no large ice chunks remain — even one unbroken cube creates an uneven pack around a Julep cup. Pour crushed ice directly from the bag into the glass and mound it above the rim for the classic Julep presentation.
Frequently Asked Questions
Why does a Mint Julep require crushed ice?
Crushed ice is essential to the Mint Julep for two functional reasons: thermal and textural. A dense pack of fine crushed ice creates maximum surface area contact between the ice and the bourbon, chilling the drink to near-freezing temperatures and producing the characteristic frost that forms on the outside of a traditional silver or pewter Julep cup. The fine ice also dilutes the spirit more rapidly, producing a very cold, lightly diluted drink that is sipped slowly over time as the ice gradually melts. This specific temperature, dilution rate, and serving vessel combination define the Julep as distinct from any other spirit-over-ice format.
What is a Lewis bag and why is linen used?
A Lewis bag (also called a Lewis Bag, named for the bar supply company that popularized it) is a heavy canvas or linen bag designed specifically for making crushed ice. Linen is used because it is durable enough to withstand repeated mallet strikes, thick enough to prevent ice shards from puncturing through, and absorbent enough to keep the ice slightly damp without becoming waterlogged. The absorption property is important: a damp linen bag wicks away the melt water from crushed ice, keeping the finished product dry and airy rather than wet and clumped. This produces the snow-like texture preferred for Juleps and Swizzles.
What cocktails require crushed ice specifically?
Crushed ice is the signature serving medium for several classic cocktails that are defined by their association with this texture. The Mint Julep (bourbon, mint, sugar, crushed ice in a silver cup) is the most famous. The Swizzle (rum, lime, falernum, crushed ice, swizzle-stick agitation) depends on crushed ice for the cracking cold temperature achieved by Swizzle technique. Tiki cocktails like the Zombie and the Painkiller are traditionally served over crushed ice. The Queen's Park Swizzle, the Caipirinha (often made with crushed ice), and Mojitos in the Cuban tradition all specify or benefit from crushed ice.
Can I make crushed ice without a Lewis bag?
Several alternatives exist but each has trade-offs. A heavy-duty zip-lock bag inside a clean towel can be struck with a rolling pin for small quantities. Some high-powered blenders can produce crushed ice, though results are less uniform and very wet. Commercial ice crushers (electric or hand-crank) produce consistent crushed ice but require a dedicated appliance. A Lewis bag and wooden mallet is the most efficient manual method and produces the driest, most evenly crushed ice because the linen absorbs excess moisture. For professional Julep service, the Lewis bag is the standard.
How do you make a proper Mint Julep with crushed ice?
Combine 4–6 mint leaves with 15ml simple syrup (or 1 teaspoon sugar) in a Julep cup and gently press the mint against the side of the cup — do not muddle aggressively. Add 60ml bourbon (high-rye bourbons like Woodford Reserve or Bulleit are traditional) and fill the cup three-quarters with freshly made crushed ice. Stir with a bar spoon, pulling upward from the bottom to integrate and add more crushed ice until the cup is mounded above the rim. Garnish generously with a mint bouquet inserted near the drinking lip so the aroma rises with each sip. The exterior of a proper Julep cup should frost immediately.
About
The Lewis bag and mallet are tools rooted in the physical geography of American cocktail history, specifically the culture of the American South where crushed ice became essential to its most celebrated cocktail. The Mint Julep, with origins documented in the early 19th century as a morning restorative among Virginia planters and tavern keepers, demanded a specific form of ice — fine, almost snow-like in texture, densely packed — that could only be produced by manually breaking large ice blocks down through repeated striking. The Lewis bag method was a refinement of this necessity, providing a contained crushing surface that produced more uniform results than striking ice on a bar top.
The specific choice of canvas or linen as the bag material reflects practical knowledge developed through bar practice. Unlike plastic or rubber bags, linen actively wicks away the melt water that accumulates when ice is crushed, keeping the finished product dry and loose rather than wet and matted. This moisture management is the difference between crushed ice that flows freely into a Julep cup and packs around the mint with airy density, and crushed ice that clumps in wet masses that settle unevenly and melt too quickly. The linen absorbs the water phase while retaining the ice phase — a simple physical separation that produces a better cocktail ingredient.
In the broader context of Tiki culture, where crushed ice is the foundation of both flavor dilution and visual presentation, the Lewis bag became a standard piece of mise en place behind bars committed to the idiom. Jeff Berry, whose research into original Tiki recipes helped drive the category's revival, notes that Don Beach's original Zombie and other landmark Tiki cocktails were designed around the specific temperature, dilution, and texture of properly made crushed ice — a parameter as important to the recipe as the spirit ratios themselves.
