How to Can Peaches in Syrup in Canada

Canning peaches in syrup is the original way to extend the Niagara and Okanagan peach seasons through the winter. A jar of home-canned peach halves in light syrup is something between a dessert and a breakfast staple — and far better than anything from a supermarket can.

One thing to know before you start: bernardin.ca publishes no plain peaches-in-syrup recipe. Both peach recipes in their Fruit category are flavoured specialties. The section below says exactly what they do publish, and this page uses the one figure of theirs that covers plain halves.

Corrected 31 Aug 2026: this page no longer claims that bottled lemon juice is required for safe acidity, no longer states a pH for peaches, and no longer describes itself as the Bernardin method. Bernardin publishes no plain peaches-in-syrup recipe, and neither of their two peach recipes contains any acid at all — so a mandatory acid rule sat on this page under their name and was never theirs. The lemon juice is still suggested, now plainly as ours. The 1 L processing time this page used to publish had no Bernardin source of any kind and has been withdrawn rather than hedged; the 500 mL time stays because Bernardin publishes it for peach halves. No figure kept on this page is unsourced.

Corrected 19 September 2026: a brandied-peaches variation has been removed, along with the 2 tbsp of brandy per jar it specified and the two-month refrigerated window it gave. Both figures were ours and neither was attributed. The variation also told you to add the brandy before processing and then, one sentence later, not to water-bath can boozy peaches — and the reason it gave, that alcohol in heat processing is not Bernardin-tested, is contradicted by the recipe this page takes its 20 minutes from: Ginger Bourbon Peaches is a Bernardin boiling-water-canner recipe that contains bourbon. No spirit quantity and no refrigerated window are offered in their place.

What Bernardin actually publishes for peaches

Searching bernardin.ca’s Fruit category returns two peach recipes, and neither is a plain pack in syrup. Both are flavoured specialties. This matters because the times below are theirs and the rest of this page is ours:

Bernardin recipe	Jars	Cut	Processing time
One-of-a-kind Peaches	7 × 250 mL	Quartered	15 minutes
Ginger Bourbon Peaches	5 × 500 mL	Halves	20 minutes at up to 305 m

Both add a herb, spice or spirit per jar; both fill peaches to 2 cm and then top with syrup to 1 cm headspace; both use Fruit-Fresh for colour only, and Ginger Bourbon calls it optional outright.

Note on the One-of-a-kind time. Bernardin’s own page disagrees with itself — the summary header says 10 minutes and the directions say 15. We follow the directions, which is the site’s standing rule after a summary box led us to publish one chicken time where Bernardin publishes four.

What this page takes from them, and what it doesn’t. The 20 minutes below is Bernardin’s, for peach halves in 500 mL jars, from Ginger Bourbon Peaches — it is not “Bernardin’s peaches time,” because there is no such thing. Everything else here — the syrup table, the optional lemon juice, the variations — is ours.

Pick your peaches

Same rules as peach jam:

• Freestone (Redhaven, Loring, Cresthaven, Veteran, Reliance) — clingstones are too hard to halve cleanly
• Ripe but firm — soft peaches turn to mush; rock-hard peaches won’t develop full flavour
• Local Canadian — Niagara or Okanagan, picked within a week. Supermarket imports were picked underripe and never finished developing.

For 6 × 500 mL jars you need about 1.8 kg of peaches. Scale up in the same proportion for a bigger batch — about 3 kg (12-18 large peaches) is twice this recipe.

What you need

• 1.8 kg ripe Canadian freestone peaches
• Granulated sugar — amount depends on syrup level (see below)
• Water
• Optional: bottled lemon juice — ½ tbsp per 500 mL jar. Ours, not Bernardin’s; see the note above.
• Bernardin 500 mL jars (wide-mouth recommended for halved peaches — see the jar guide), fresh SNAP lids, bands
• Standard canning kit — jar lifter, headspace tool, funnel, water-bath canner, ladle, slotted spoon, paring knife (which canner to buy)
• Large bowl of ice water for blanching
• Optional: 1 tsp ascorbic acid powder dissolved in 4 cups cold water (a holding bath that prevents browning before processing)

Choose your syrup

Syrup	Sugar	Water	Sweetness profile
Extra-light	1.25 cups	5.75 cups	Barely sweet; lets fruit flavour dominate
Light	2.25 cups	5.25 cups	Mildly sweet; popular for breakfast use
Medium	3.25 cups	5 cups	The Canadian default — what most home recipes assume
Heavy	4.25 cups	4.25 cups	Dessert-level sweet; rarely used now
Water-packed	0	6 cups + 2 tbsp bottled lemon juice	No sugar; softer texture but safe
Juice-packed	Use unsweetened apple or white grape juice	—	Substitute fruit juice 1:1 for syrup; popular for sugar-restricted diets

The recipe in this article assumes medium syrup (3.25 cups sugar : 5 cups water), which yields about 7 cups. Make the full quantity and use what the jars take; leftover syrup keeps in the fridge.

Method

Step 1: Blanch and peel

1. Bring a large pot of water to a rolling boil.
2. Have a large bowl of ice water beside the stove.
3. Score a shallow X in the bottom of each peach.
4. Drop peaches in boiling water for 30-60 seconds.
5. Transfer immediately to ice water.
6. Slip skins off starting at the X.

Step 2: Halve and pit

1. Cut each peach in half along the natural seam.
2. Twist the halves apart — should separate cleanly on a freestone.
3. Remove the pit.
4. Optional: drop peach halves into the ascorbic-acid holding water as you work, to prevent browning. (Not strictly required if you work quickly.)

A 1.8 kg batch takes about 20 minutes to blanch, peel, and halve.

Step 3: Make the syrup

1. In a large pot combine sugar and water for your chosen syrup level (see the table).
2. Bring to a simmer over medium heat, stirring until sugar fully dissolves.
3. Keep hot at a low simmer until you’re ready to pack jars.

Step 4: Hot-pack the peaches

1. Drain the peach halves from the holding water if you used it.
2. Add peach halves to the simmering syrup. Heat 1-2 minutes until heated through — don’t boil long or they soften.
3. Have your water-bath canner simmering with enough water to cover jars by 2.5 cm.
4. Have hot jars ready, fresh SNAP lids on the counter.

Step 5: Pack the jars

1. If you are using it, add ½ tbsp bottled lemon juice to each 500 mL jar. This is our suggestion, not a Bernardin instruction.
2. Using a slotted spoon, lift hot peach halves from the syrup and pack into jars cavity-side down, layered slightly overlapping like roof tiles. Pack snugly — peaches will float if loose.
3. Pour the hot syrup over the peaches, covering them completely and leaving 1 cm (½ inch) headspace.
4. Run the headspace tool down the side of each jar to release air bubbles. Top up syrup if needed.
5. Wipe rims with a damp clean cloth.
6. Apply fresh SNAP lids fingertip-tight.

Step 6: Process

1. Lower jars into the canner. Water should cover by 2.5 cm.
2. Bring water back to a rolling boil.
3. Process 500 mL jars for 20 minutes at altitudes up to 305 m — Bernardin’s figure for peach halves in 500 mL jars, from Ginger Bourbon Peaches.
   • We do not publish a time for 1 L jars. Bernardin publishes peaches in 250 mL and 500 mL only, and we will not invent a figure for a larger jar. Use 500 mL, or follow a 1 L time from a tested recipe you have in front of you.
4. Adjust for altitude per our altitude-adjustments guide. Most Canadian cities need 5-10 extra minutes.
5. Remove jars with the jar lifter. Cool 24 hours undisturbed on a towel.
6. Check seals.

If a jar doesn’t seal: the 24-hour rule applies.

Storage

• Cool, dark, dry place at room temperature
• Best quality 12 months — Bernardin’s guidance is to use home-canned food within one year. That is a quality window, not an expiry: the jar is as safe as the process made it. Colour, flavour and texture fade.
• After opening: refrigerate, use within one week (HealthLink BC)
• Inspect before opening — peaches may darken near the top of the jar where there’s slight air exposure; that’s normal oxidation, safe

Corrected 20 September 2026: this page previously gave an after-opening window of 5-7 days, a shorter figure specific to this food that no authority we could find publishes. HealthLink BC File #22 publishes one week for any opened home-canned container — “Once the container has been opened, refrigerate leftovers, and use within one week.” This correction makes the window longer rather than shorter: anyone who discarded a jar at 5-7 days was going by a number we had no source for. The shelf life of the sealed jar is unchanged.

Corrected 22 September 2026: a bullet near the foot of this page said a six-jar batch “lasts 6 months”. This page’s own storage section says 12 months, which is Bernardin’s guidance for home-canned food, and its shelf-life FAQ says the same — so the page halved its own keeping window in a sentence about value. The figure is gone rather than restated; the storage section above owns it. Anyone who discarded good peaches at six months was going by a number this page contradicts twice. The safety of a sealed jar was never at issue: it rests on the process, and a spoilage sign is what ends a jar.

Variations

Spiced peaches

Add 1 cinnamon stick and 3 whole cloves to each jar before packing. Adds warm spice; great over vanilla ice cream.

Ginger peaches

Add 2-3 thin slices of fresh ginger per jar. Slight kick.

Peaches with vanilla bean

Add a 5 cm piece of vanilla bean to each jar (split lengthwise). Luxurious for gift jars.

Peach halves vs slices

Halves: classic, photogenic, easier to remove from the jar whole. Slices: pack more peaches per jar; better for baking applications where you’d cut them anyway. We have no source for a slice time. Bernardin publishes quarters at 250 mL (15 minutes) and halves at 500 mL (20 minutes), and nothing for slices. If you slice, you are outside what either recipe covers.

Juice-packed peaches (no added sugar)

Same cut, same time — replace the syrup with unsweetened white grape juice or apple juice. It is the packing liquid that changes, not the cut: halves stay halves, and the 20 minutes above is still the figure. This section used to be headed “sliced peaches”, four lines under the line saying we have no source for a slice time. Suitable for sugar-restricted diets. Slightly softer texture; same shelf life.

How to use canned peaches

• Over breakfast yogurt or oatmeal with the syrup
• Baked in a peach cobbler in February when you remember August
• In peach upside-down cake
• Sliced over vanilla ice cream with a splash of the syrup
• In smoothies — frozen-into-cubes or straight from the jar
• As a side for pork chops or grilled chicken
• Peach syrup for cocktails — the syrup that’s left after the peaches are gone makes excellent peach bellinis or bourbon cocktails
• Eaten straight from the jar as a snack
• Sliced into salads with prosciutto and burrata
• As a topping for pancakes or French toast

Common problems

• Peaches floated to top. Hot-pack helps; pack snugly. Slight floating is normal. The fruit is safe regardless.
• Peaches darkened in jar. Oxidation from air at the top. Cosmetic only; safe. Use ascorbic acid holding bath next time, or pack peaches more tightly to leave less air space at the top.
• Syrup is cloudy. Hard water in your canner; harmless. Or it could indicate spoilage if accompanied by bulging lid or off smell — inspect carefully.
• Peaches mushy. Over-ripe to start, or over-processed. Use firmer peaches; process for exactly the recipe time.
• Pit stuck in a peach half. Clingstone variety. Cut around the pit next batch; or buy freestones.
• Jar didn’t seal. The 24-hour rule.
• Bulging lid after months. Discard the entire jar immediately. Possible spoilage. Don’t taste.

Why home-canned peaches beat the supermarket version

• Fresher fruit — local peaches at peak vs imported peaches picked underripe
• Less sugar by default — supermarket canned peaches are heavy syrup; you can choose light or even sugar-free
• Better flavour — local-variety peaches have terroir that commercial canners ignore
• Cheap — Niagara peaches at $1.50/lb at the farm stand vs $4 for a 540 mL commercial can. A 6-jar batch is ~$25 in ingredients.
• Heritage Canadian preserve — generations of Niagara and Okanagan households canned peaches every August

Yield expectations

• 1.8 kg whole peaches → 6 × 500 mL jars (about 5 peach halves per jar)
• Syrup yield: ~7 cups from the 3.25-cup-sugar / 5-cup-water recipe

A typical Canadian household puts up a dozen or more jars a year. The Niagara peach window is about 6 weeks — plan to make 1-2 batches across the season.
