Jigger Pour
Jigger pour is the bartending technique of using a jigger measuring tool to accurately portion liquid ingredients when making cocktails, typically measuring 1.5 oz on one side and 1 oz on the other.
Jigger pour is the bartending technique of using a jigger—a double-sided measuring tool—to accurately measure liquid ingredients when making cocktails. This method ensures consistent drink quality and precise alcohol portions, making it the gold standard in professional bars.
How Jigger Pouring Works
Bartenders hold the jigger between their index and middle fingers, position it over the mixing vessel, and pour until liquid forms a meniscus (convex surface tension curve) at the rim. A standard jigger measures 1.5 oz on one side (the “jigger” measurement) and 1 oz on the other (the “pony” side). The hourglass shape with two conical cups joined at the base allows bartenders to flip the tool and measure different volumes without reaching for multiple devices.
Professional bartenders fill the jigger completely to the rim for accuracy. The meniscus should be slightly above the edge due to surface tension—this indicates a full, precise pour. Underfilling by even a quarter-ounce affects drink balance and gives customers less alcohol than they’re paying for.
Jigger Pour vs Free Pour
Free pour relies on counting and speed pourers to estimate measurements without tools. While free pouring looks impressive and speeds up service during rushes, it’s inconsistent and leads to overpouring that cuts into profits. Bar managers calculate that a bartender who overpours by just 1/4 oz per drink can cost a venue thousands in lost revenue monthly.
High-volume bars often mandate jigger use specifically to prevent this waste. The few extra seconds per drink pay for themselves in controlled portions and predictable inventory. Craft cocktail bars use jiggers exclusively because recipes with multiple spirits, liqueurs, and modifiers require precision to achieve the intended flavor profile.
Types of Jiggers
Classic bell jiggers have a wide cone shape and are the most common in American bars. Japanese-style jiggers are tall and narrow with measurement lines inside, offering better precision for complex recipes. Thimble or pub jiggers have a squat design that fits easily in apron pockets. Measuring cup-style jiggers look like miniature beakers with multiple measurement markings.
Jigger sizes range from 0.5 oz to 2.5 oz depending on the bar’s needs. Always verify your jigger’s actual measurements—some vintage or imported jiggers use different standards. A bartender at a new station should test jigger volumes by pouring into a marked shot glass to confirm accuracy before service starts.
Origin of the Term
The name “jigger” likely comes from the Royal British Navy, either referencing the jiggermast (smallest mast on a ship, suggesting a small measurement) or naval slang for sailors’ daily rum rations. Cornelius Dungan of Chicago patented the double-sided design in 1893, but the measuring practice predates his patent. Another theory suggests American bartenders shortened “thingamajig” to “jigger” when referring to the small measuring device, though this has less historical support.
Common Uses
Bartenders use jigger pour technique throughout service to measure spirits, liqueurs, juices, and syrups for cocktails. Bar managers require jigger use during training periods to teach proper proportions, and many establishments mandate it during all shifts to control costs. Craft cocktail bars rely on jiggers for recipes with multiple modifiers where precision affects the final taste. High-volume venues use jiggers specifically during inventory-sensitive periods or when training new staff to prevent overpouring waste.
