Simple Syrup, Sour Mix and Super Juice: Bar Ingredients from Bulk Powders

Behind every fast, consistent cocktail program there is a prep list: simple syrup, sour mix, citrus stock. The bars that run these programs profitably have quietly moved away from squeezing cases of limes every afternoon and toward gram-scale recipes built on bulk powders — granulated sugar, citric acid, malic acid and a few functional ingredients. This guide covers the three workhorses of modern bar prep: simple syrup (1:1 and 2:1), the super juice technique that stretches citrus roughly eightfold, and a house sour mix built from syrup and acids. All dosages are given in grams and presented as classic starting points — weigh, taste, and adjust to your program.

Simple Syrup: The Foundation (1:1 and 2:1)

Simple syrup is nothing more than granulated sugar dissolved in water, but the ratio you choose changes sweetness, texture and shelf life.

1:1 simple syrup

  • Recipe: 500 g sugar + 500 g (500 ml) water. Stir off heat or warm gently until clear — do not boil, which evaporates water and drifts your ratio.
  • Yield: about 810 ml of syrup at roughly 50 Brix equivalent by weight.
  • Character: lighter body, easy to pour and to substitute 1:1 for fresh syrup in most spec sheets.
  • Shelf life: about 2 to 4 weeks refrigerated in a sanitized bottle.

2:1 rich syrup

  • Recipe: 1,000 g sugar + 500 g water. The high sugar concentration lowers water activity, which is why rich syrup keeps longer.
  • Character: more viscosity and mouthfeel per millilitre; you use roughly two thirds the volume of a 1:1 syrup for the same sweetness.
  • Shelf life: commonly 1 to 3 months refrigerated.

Pro tip: weigh both the sugar and the water. Volume measurements of sugar vary with crystal size and packing; a scale is the only way two bartenders on two shifts make the same syrup.

Super Juice: Stretching Citrus About 8x

The super juice technique has spread through cocktail bars worldwide because it attacks the two biggest problems with fresh citrus: cost and waste. Instead of juicing limes and discarding the peels, super juice extracts flavour from the peels with food-grade acids, then rebuilds the juice with water. The classic method runs like this:

The general technique

  • Peel the limes. Remove the zest with a peeler, avoiding as much white pith as possible. Weigh the peels — everything scales from this number.
  • Make an oleo citrate. Toss the peels with citric acid and malic acid. A classic starting point for lime is 66 g citric acid + 33 g malic acid per 100 g of peels. Let the mixture sit 60 to 90 minutes: the acids draw the aromatic oils out of the peels, just as sugar does in a traditional oleo saccharum.
  • Add water and juice. Blend the oleo citrate with about 1,500 g of water per 100 g of peels, then add the fresh juice squeezed from the peeled limes. Blend briefly and fine-strain.

The result tastes remarkably close to fresh lime juice, with a yield of roughly 8 times what the same fruit gives when juiced alone. For lemon super juice, the classic starting point shifts the acid blend toward citric — around 90 g citric acid + 10 g malic acid per 100 g of peels — because lemons are naturally dominated by citric acid, while limes carry more of the malic character.

Why it works

Most of a citrus fruit's aroma lives in the peel oils, not the juice. Fresh juice supplies acidity plus a little aroma; super juice supplies the same acidity from powdered acids and pulls far more aroma from the peels you would otherwise throw out. Two practical advantages for a bar:

  • Stability: fresh lime juice degrades noticeably within hours; super juice typically holds its profile for one to two weeks refrigerated.
  • Cost control: when lime prices spike, an 8x yield changes the economics of every margarita and daiquiri on the menu.

House Sour Mix: Syrup Plus Acids

If super juice is a citrus replacement, sour mix is a complete cocktail component: sweetness and acidity balanced in one bottle. Commercial sour mixes are widely disliked for tasting flat and artificial — but a house version made from real sugar and food-grade acids is a different product entirely. A classic starting point for one litre:

Ingredient Amount Role
Water 660 g (660 ml) Base
Granulated sugar 330 g Sweetness and body
Citric acid 25 g Sharp, lemon-lime acidity
Malic acid 8 g Rounder, green-apple acidity

Dissolve the sugar in the water first, then whisk in the acids. This lands near the sweet-tart balance of a classic shaken sour; from there, adjust the citric-to-malic ratio to taste. More malic reads riper and juicier; more citric reads brighter and sharper. Some programs add a small pinch of salt (0.5 to 1 g per litre) to lift perceived flavour.

For a version closer to fresh sour mix, replace part of the water with super juice or fresh citrus — the acid powders then act as reinforcement rather than the sole acid source.

Foam Without Egg White

Sours traditionally get their silky cap from egg white, but raw egg brings allergen, storage and vegan-menu problems. Bars solve this several ways: aquafaba, commercial foamers, or a hydrocolloid route using xanthan gum. Xanthan does not foam on its own the way protein does, but at very low doses it thickens the liquid enough to stabilize the bubbles created by a hard dry-shake, producing a finer, longer-lasting foam and a rounder mouthfeel.

  • Starting dose: 0.5 to 1 g of xanthan gum per litre of sour mix (0.05 to 0.1%). At this level it stabilizes texture without turning the mix slimy.
  • Dispersion tip: xanthan clumps in plain water. Pre-blend it with 10x its weight of sugar before whisking in, or shear it in with an immersion blender.
  • Technique: dry-shake (no ice), then shake with ice as usual. The foam sets as you strain.

Extending Shelf Life: Small Preservative Doses

Refrigeration and sanitized bottles are the first line of defence for any syrup or mix. When a program needs batched product to survive a full week of service — or to be distributed across multiple venues — small doses of standard beverage preservatives are the classic answer.

  • Sodium benzoate: a typical beverage-industry starting point is 0.2 to 0.5 g per litre (200 to 500 ppm). Benzoate is only effective in acidic products — below roughly pH 4.5, which sour mix and super juice easily satisfy.
  • Potassium sorbate: also dosed around 0.2 to 0.5 g per litre; it targets yeasts and moulds and is often paired with benzoate for broader coverage.
  • Combined use: many formulators split the dose — for example 0.25 g of each per litre — rather than maxing out a single preservative.

Weigh preservatives on a 0.01 g scale, dissolve them fully, and verify that your usage complies with the food additive regulations applicable to your product and jurisdiction. Preservatives extend life; they do not replace clean bottles, refrigeration and dated labels.

Quick Reference: Gram Dosages at a Glance

Preparation Starting-point formula
Simple syrup 1:1 500 g sugar + 500 g water
Rich syrup 2:1 1,000 g sugar + 500 g water
Lime super juice Per 100 g peels: 66 g citric + 33 g malic + 1,500 g water + juice of the limes
Lemon super juice Per 100 g peels: 90 g citric + 10 g malic + 1,500 g water + juice of the lemons
Sour mix (1 L) 660 g water + 330 g sugar + 25 g citric + 8 g malic
Foam stabilizer 0.5–1 g xanthan gum per litre
Preservation 0.2–0.5 g/L sodium benzoate and/or potassium sorbate (pH < 4.5)

Every figure above is a classic starting point, not a spec sheet. Batch small, taste against your house standards, and lock in your own numbers.

Why Buy These Ingredients in Bulk

A busy bar goes through kilograms of sugar and hundreds of grams of acids every month. Buying citric acid in tiny retail jars can cost several times the per-kilogram bulk price, and the powders themselves — citric acid, malic acid, benzoate, sorbate, xanthan — are shelf-stable for years when kept dry and sealed. LiquidShop supplies all of these as food-grade ingredients in bulk by the kilogram, at B2B pricing, shipped across Canada. Stock your prep station once and batch with confidence:

With a scale, six powders and the formulas above, your bar can produce syrup, citrus and sour mix that are cheaper, more consistent and far less wasteful than the case-of-limes routine — every single shift.
