Peach
Juice

One pound of peaches (approximately 454g) yields roughly 250–295ml in a cold press juicer — about 8.5–10 oz, or just under a standard glass. A masticating juicer produces a similar range: 250–295ml. Centrifugal juicers extract noticeably less from soft stone fruit — typically 180–235ml from the same pound.

Peaches are lower-yield than most fruits. Their high pulp content and soft flesh mean a meaningful portion of the juice stays trapped in the fiber, especially with centrifugal extraction. For accurate yield on any specific quantity, use the calculator.

About 4–6 medium peaches (roughly 500–600g with pits removed) will fill an 8 oz cup in a cold press or masticating juicer. Medium peaches weigh 130–175g each, and you'll lose roughly 10–12% to the pit.

Centrifugal juicers need more — plan on 6–8 medium peaches for the same cup. If you're working by weight rather than count, 450–550g of prepped, pit-free peach flesh is a reliable target per cup.

A 5 lb bag of peaches (approximately 2,268g) yields roughly 1,200–1,450ml in a cold press juicer — just over a quart, or about five 8 oz glasses. The same bag in a centrifugal juicer produces closer to 900–1,180ml.

Pit weight is a real factor here. Five pounds with pits is closer to 4.4 lbs of usable flesh — plan accordingly. For weekly batch juicing, one 5 lb bag typically covers 3–5 days at 8 oz per day in a cold press juicer.

Ripeness is the single biggest variable with peaches. Very ripe, soft peaches juice easily but can turn to foam or thick puree in high-speed juicers. Underripe peaches are firmer and yield better-defined juice, but less total volume. The sweet spot is peaches that are ripe but still slightly firm — fragrant at the stem end, with minor give when pressed.

Other factors: variety (white peaches are lower-sugar and often lower-yield than yellow), prep (pit removal, slicing into smaller pieces increases contact with extraction surfaces), and temperature (room-temp peaches extract better than cold). Skin-on juicing adds tannins but doesn't meaningfully change yield.

Yes, and peaches are one of the produce items where it matters most. Centrifugal juicers introduce significant oxidation via high-speed blades — peach juice is particularly vulnerable because its vitamin C content is modest to begin with (8.5mg per 100ml in a cold press juicer, potentially 20–30% lower from centrifugal).

Cold press and masticating juicers also retain more beta-carotene and the polyphenol compounds (chlorogenic acid, catechins) that give peach juice its antioxidant value. The nutrition figures on this page reflect cold press / masticating extraction. Centrifugal peach juice will have measurably lower antioxidant activity and slightly reduced vitamin C.

Moderate — about 13g of natural sugar per 100ml (roughly 31g per standard 8 oz cup), similar to apple juice. The sugars are primarily sucrose, glucose, and fructose from the peach's natural sweetness.

Peach juice has a moderate glycemic index, and because fiber is largely removed during juicing, blood sugar impact can be quicker than eating a whole peach. If you're monitoring sugar intake, peach juice is best consumed in smaller servings (4–6 oz) or blended with lower-sugar produce like cucumber or celery to moderate sweetness.

No — you can juice peaches skin-on, and the skin contributes antioxidants (particularly anthocyanins in yellow-skinned varieties). The peel adds a mild tannic note that balances the sweetness.

That said, peach skin is often treated with pesticides — if you're not using organic peaches, a thorough wash is essential. Heavily sprayed conventional peaches are worth peeling. Organic peaches: leave the skin on. Either way, always remove the pit before juicing — it contains amygdalin, a compound that can release small amounts of hydrogen cyanide.

Fresh peach juice is sweet, slightly floral, and mildly tart — significantly more aromatic than bottled peach juice. The flavor is closest to biting into a perfectly ripe yellow peach: bright, fruity, and slightly honeyed.

It pairs exceptionally well with ginger (the spice cuts the sweetness and extends the aroma), lemon or lime (adds brightness and preserves color), and cucumber (balances the sugar with a clean, neutral note). For green juice blends, peach softens the bitterness of kale or spinach without completely masking them. Among stone fruits, it blends naturally with mango and pear.

Cold press peach juice: 48–72 hours refrigerated, sealed in an airtight container. Peach juice oxidizes quickly — it will turn from golden-orange to brown within hours if exposed to air. Fill containers completely to minimize headspace and add a small squeeze of lemon juice to slow oxidation.

Centrifugal peach juice degrades faster — best consumed within 24 hours. For longer storage, peach juice freezes well (up to 3 months) and retains flavor better than most fruits when frozen.

Peach juice doesn't carry the specific carotenemia risk of carrot juice or the oxalate concern of beet juice, but large quantities add up in sugar quickly. A 16 oz serving delivers roughly 62g of sugar — comparable to several cans of soda. Daily intake above 8–12 oz is probably more than most people need from a single juice source.

The other consideration: peach skin contains sorbitol, a sugar alcohol that in large amounts can cause digestive discomfort in sensitive individuals. This is diluted significantly in juice, but highly concentrated fresh peach juice in large quantities may cause loose stools for people with IBS or fructose sensitivity.
