Bitters Bottle
A bitters bottle is a small glass bottle, 9cl or 20cl in Urban Bar’s own bitters bottles, with a dasher top that lets out a few drops at a time. You decant bitters into it from the maker's bottle so that every dash comes out the same size. It serves any drink measured in dashes, including the Old Fashioned, the Bamboo and the Pink Gin.
About the Bitters Bottle
A Dash Is a Measurement
A dash is roughly 0.6 to 0.9ml, a little under a fifth of a teaspoon, and the dasher top is what makes it repeatable. The insert lets out a few drops per flick and no more.
Bitters are seasoning, so small errors show. The three dashes in a Bamboo come to about 2.5% of the drink: small enough to vanish in a careless pour, and strong enough to show when doubled.
The Maker's Bottle Pours Unevenly
Shop bottles of bitters have restrictor tops of their own, and how much leaves them depends on the angle and how hard you shake. Decanting into dasher bottles gives you one action for every bitters on the rail.
It also lets you label clearly. Aromatic and orange bitters look alike through brown glass, and a wrong pick is easy in a hurry.
One Sharp Flick Per Dash
Turn the bottle fully upside down over the glass and flick it down once, stopping hard. The stop does the work; a slow tilt dribbles.
Fill to the shoulder only. With the neck full, the insert floods and the first dash comes out as a stream.
Count aloud while you learn. Two dashes into a mixing glass looks like nothing, and the urge to add more is how a drink ends up over-bittered.
Tinted Glass and a Tight Insert
Light fades bitters, so amber or cobalt glass is the safer choice on an open shelf; clear glass is fine in a cupboard. A tight insert matters more than the shape of the bottle.

| Option | What comes out | Best for | Drawback |

| Dasher bottle | A dash of roughly 0.6 to 0.9ml (our measure) | Everyday bitters on the rail | Needs decanting and labelling |
| Maker's own bottle | A variable dash, set by the shake | Occasional use | Harder to repeat exactly |

| Atomiser | A fine mist | Scenting a glass or the top of a drink | Too little for a recipe dash |
In our experience bitters at full strength keep for years. The aroma goes first, so a bottle that smells faint has faded rather than spoiled.
Using the Bitters Bottle
Usage
Holding Angostura, orange bitters, Peychaud's or a house tincture on the rail, ready to dash one-handed. A firm dash from a dasher top is roughly 0.6 to 0.9ml, which is what our recipes mean by a dash.
Pro Tip
Label the base as well as the side. Caps get swapped, and three brown bitters in matching bottles look the same until you taste them.
Professional Tips
- Turn it fully upside down and give one sharp flick for each dash.
- Fill to the shoulder, not the neck, or the insert floods.
- Label the side and the base. Most bitters are brown.
- Keep it out of direct sunlight, which fades the aroma.
Alternatives
Budget Alternative
A plain glass bottle with a push-in plastic dasher insert does the whole job. An emptied maker's bottle, rinsed and refilled with the same bitters, works too.
Premium Option
A heavy cut-glass Japanese-style dasher with a metal insert. The money buys weight on the rail and a steadier dash; the drink tastes the same.
