How to Juice Citrus and How Long Juice Lasts

Fresh citrus juice is the backbone of sours, lemonades and many mocktails, and it changes noticeably after it is squeezed. Lime juice in particular loses brightness within hours, while lemon holds up somewhat better. Knowing how to juice efficiently and how long juice stays good helps you plan for a party or a busy evening.

This guide covers selecting fruit, the tools that work best, how to get more juice from each piece, and realistic timelines for using fresh juice. It also covers food-safety basics for fresh-squeezed juice, which is not pasteurized.

Choosing citrus

Pick fruit that feels heavy for its size, with thin, smooth, slightly glossy skin and a little give when squeezed. Heavy fruit usually holds more juice. Very hard limes tend to be dry; very soft ones may be past their best.

On average, a lime yields about 20 to 30 ml (roughly 3/4 to 1 oz) of juice, a lemon about 30 to 45 ml (1 to 1½ oz), and an orange about 60 to 90 ml (2 to 3 oz). Yields vary with size and season, so buy a few extra.

Tools for juicing

Handheld citrus presses, sometimes called Mexican elbow presses, are fast and keep peel oil in check because the peel is not ground. Lever or countertop presses are best for large volumes. Reamers and electric reamers extract a lot of juice but can push bitter oils and pith into it if you press too hard.

For large batches, an electric citrus juicer with a reaming cone saves time; stop when you reach the pith to avoid bitterness.

• Elbow press: quick, clean juice, small batches
• Lever press: large batches, less hand strain
• Reamer: high yield, can add bitterness
• Electric juicer: high volume, watch for pith

Getting more juice from each fruit

Bring fruit to room temperature, since cold fruit gives less juice. Roll it firmly on the counter with your palm to break down the juice sacs. Cut limes and lemons in half crosswise, and for an elbow press place the cut side down, facing the holes, so the press turns the fruit inside out.

Microwaving fruit for 10 to 15 seconds can increase yield slightly, but it can also warm the juice; let it cool before using in drinks.

How long fresh juice lasts

Juice begins changing as soon as it is squeezed. Aromatic compounds evaporate and oxidize, and some bartenders find lime juice tastes best a few hours after juicing, once its sharpest edges soften slightly. After about a day, though, most citrus juice tastes flatter and sometimes bitter.

Store juice in a clean, sealed container in the refrigerator at 4°C (40°F) or below. Use lime juice the same day for the best flavor, lemon and grapefruit within a day or two, and orange within two to three days. Discard juice that smells fermented, fizzy or off.

Food safety for fresh juice

Fresh-squeezed, unpasteurized juice can contain harmful bacteria. For most healthy adults the risk is low when fruit is washed and juice is kept cold, but pasteurized juice is the safer choice for children, older adults, pregnant people and anyone with a weakened immune system.

Wash fruit under running water before cutting, even though you do not eat the peel, since a knife carries surface bacteria into the flesh. Keep juice refrigerated and do not leave it at room temperature for more than 2 hours, or 1 hour above 32°C (90°F).

Planning for a party

Estimate how many drinks need citrus and how much each uses. Juice limes no more than a few hours before guests arrive, and lemons up to the morning of the event. Store juice in squeeze bottles in the refrigerator or on ice for easy pouring.

Save a few whole fruits for garnishes, and peel twists before juicing if you need them, since peeling a juiced half is difficult.

Common questions

Can I freeze citrus juice?

Yes. Freeze it in ice cube trays and store the cubes in a sealed bag. Thawed juice is fine for cooking and many drinks, though it tastes less vivid than fresh.

Is bottled juice a good substitute?

It works in a pinch, but it tastes duller and sometimes cooked. Add a little fresh zest or adjust syrup to compensate.

Why does my lime juice taste bitter?

Pressing too hard or reaming into the pith releases bitter compounds and oils. Use a press, stop before the pith, and strain the juice.
