Why did my lime liqueur turn cloudy after adding juice or syrup?

Expanded Explanation

Cloudiness usually comes from citrus oils meeting water (from juice or thin syrup), which forms an emulsion. It’s common and not dangerous, but it changes appearance and sometimes texture. To reduce it, keep your zest infusion separate, strain it clear, then add sugar syrup slowly while stirring.

If you want to add juice, do it in tiny increments and expect haze—lime juice contains solids and pectin. You can clarify by cold‑crashing and decanting, or by filtering through fine paper after a few days of rest. Another trick is using citric acid for brightness instead of juice; it adds “lime-like” snap without introducing pulp.

Common mistakes are adding warm syrup (shocks oils), using very low ABV, and shaking the bottle hard. Flavor impact stays great even when cloudy, so decide if clarity matters for your bottle style. Store refrigerated if you used juice; it preserves freshness and slows oxidation.
