Super Juice Calculator

Super juice is the most consequential bar prep innovation of the last decade. The premise is simple: most of a lime's flavor lives in its peel oils, not its juice. Capture both — peel oil and juice — using a buffered citric-malic acid solution as the carrier, and you produce a citrus liquid that tastes more like the fruit than fresh juice does, yields 3–4× the volume from the same fruit count, and holds for two weeks instead of twenty-four hours.

1. Peel. Use a Y-peeler. Take wide strips of the colored zest only — avoid the white pith, which contributes bitterness without flavor. Weigh exactly to spec.
2. Combine peel, acid, water. In a sanitized container, combine the peel, the acid blend (citric only for lemon, citric + malic for lime and grapefruit), and the distilled water. Stir until the acid dissolves fully.
3. Macerate. Seal and refrigerate for 4 hours minimum, 12 hours ideal. Do not skip this step. The acid solution extracts peel oils slowly; rushing this stage costs you ~40% of the flavor.
4. Juice. While the peel macerates, juice the same fruit (now peeled) using your standard procedure. The yield will be lower than from un-peeled fruit (~25% vs. ~32%), which is already accounted for in the build sheet.
5. Combine and strain. Strain the peel-acid macerate through a fine chinois, pressing the peels to extract every drop. Combine with the fresh juice. Adjust to final volume with additional juice or filtered water if needed.
6. Label and chill. Time-stamp, date, batch number. Refrigerate at 38°F. Shelf life is approximately 14 days, but taste at day 10 — pH stability does not equal flavor stability.

Substitution ratio: 1:1 with fresh juice. Super juice is engineered to read identically to fresh-pressed juice in equal volume. A daiquiri specced with 0.75 oz fresh lime juice should use 0.75 oz lime super juice. Do not adjust the spec.

Do not heat. The peel oils are volatile. Any heat above 80°F during preparation will drive them off and you will lose the entire flavor advantage over fresh juice. This is a cold-process recipe.

pH matters more than you think. Target pH 2.2 for lime super juice. If you measure higher (less acidic), the shelf life shortens dramatically and you risk microbial growth. A calibrated pH meter is not optional for super juice production — it is the difference between a 14-day product and a 5-day product.

Where it fails. Super juice is not a magic substitute. It will not perform identically in clarified cocktails (no proteins to clarify), in ice cream applications, or in anything garnish-dependent. For Margarita salt rims, Daiquiri service, or any high-volume sour application: ideal. For show-pieces with floated juice: stick with fresh.
