Lock In July Prices: Freeze, Can and Pickle the Glut

July is the cheapest month of the year to fill a Swiss pantry. Strawberries at CHF 3.50 per 500 g, tomatoes under CHF 3 per kilo, zucchetti practically given away. Freeze, can, pickle or dry that glut now and you will eat July prices in January, when the same basket costs 60–100% more.

Preserving sounds like grandmother territory, but the maths is thoroughly modern: one Saturday afternoon with a freezer, a big pot and a few jars locks in CHF 80–150 of winter savings for a typical household. Here is what to buy in July 2026, which method suits which produce, and three projects any beginner can finish this weekend.

Why is July the month to buy big?

The Swiss harvest peaks in July, and supermarkets respond with volume Aktionen to move it. In early July 2026 the pattern looks like every year — only the numbers matter: Swiss strawberries at CHF 3.50 per 500 g on Aktion, raspberries and currants around CHF 2.95 per 250 g, Swiss tomatoes at CHF 2.50–2.95 per kilo, zucchetti near CHF 2 per kilo, green beans at CHF 3.50–3.90 per kilo, and from mid-July Valais apricots in tray promotions under CHF 4 per kilo.

Almost every one of those prices roughly doubles by January, when the same produce arrives from Spain or Morocco. That gap is the profit margin of preserving — and if you want to push the buy price even lower, self-harvest fields sell berries by the kilo below even Aktion prices, in exactly the quantities preserving needs.

Freezing: the beginner method that locks in the most

Freezing is cheap, fast and forgiving — and it preserves more vitamins than most people expect. What survives brilliantly: berries, blanched green beans, grated zucchetti, cooked tomato sauce and apricot halves. What does not: whole salad tomatoes, cucumbers and lettuce, which turn to mush as ice crystals break their cell walls.

Two techniques do most of the work. First, tray-freezing: spread berries in a single layer on a tray, freeze for two to three hours, then pour them into bags — they stay loose instead of fusing into a block. Second, blanching: plunge beans or zucchetti sticks into boiling water for two to three minutes, then straight into ice water. Blanching stops the enzymes that would otherwise ruin colour, texture and flavour within weeks.

Frozen July produce slots directly into the routine of freezer meals from supermarket basics — the sauce, the vegetables and half the fruit for winter baking are already portioned.

Einmachen: canning without the fear

Canning intimidates beginners, mostly because of one word: botulism. The safety logic is simple. High-acid foods — tomatoes with a splash of lemon juice, fruit in syrup, anything pickled in vinegar — are safe to process in a boiling water bath at home. Low-acid vegetables like plain beans or zucchetti are not; they need a pressure canner. As a beginner, can the acidic things and freeze the rest.

The equipment is minimal: glass jars with intact rubber rings or new twist-off lids, sterilised for ten minutes in boiling water, filled hot, then processed in a large pot of boiling water — 30 to 40 minutes for litre jars of tomato sauce. Since the Swiss tomato season runs at floor prices into September, you can repeat the batch whenever the Aktion returns. For hygiene fundamentals, the Federal Food Safety and Veterinary Office (BLV) publishes plain-language guidance on safe home food handling.

Pickling and drying: the flavour plays

Pickling is the fastest win of all. Quick fridge pickles — cucumbers in a hot brine of one part vinegar to one part water with salt, sugar, dill and mustard seeds — are ready in 48 hours and keep four to six weeks. Water-bath processed pickles keep a year. Pickled zucchetti ribbons and beans work the same way and rescue any glut the freezer cannot absorb.

Drying concentrates flavour rather than volume: halved cherry tomatoes at 90°C in the oven for six to eight hours become intensely sweet, and herbs simply air-dry in bunches. Store dried tomatoes in oil in the fridge and use them within weeks, or dry them fully and jar them for months.

What should you preserve — and what does it save?

The table below is the shopping brief: what to buy at July 2026 Aktion prices, how to lock it in, and what the same food costs in winter.

Now the honest cost math, effort included. Ten kilos of Aktion tomatoes (CHF 29.50) become roughly eight litres of sauce in one afternoon; comparable ready sauce or January tomatoes cost CHF 55–70. Four kilos of July strawberries cost CHF 28 against CHF 55 for the January equivalent. Add a round of pickles and beans, subtract jars and energy (about CHF 10–15 the first year, less after), and one relaxed Saturday returns CHF 80–150 — for perhaps four hours of work, much of it waiting for pots.

Three beginner projects for this weekend

1. Batch tomato sauce. 10 kg Aktion tomatoes, 4 onions, olive oil, salt, basil. Chop, simmer 90 minutes, blend. Freeze in 500 ml portions, or add a tablespoon of lemon juice per litre jar and water-bath for 40 minutes.
2. Berry freezer packs. Tray-freeze strawberries, raspberries and currants for two to three hours, then bag in 300–500 g portions — smoothie, porridge and cake supplies until spring.
3. Quick pickled cucumbers. Pack sliced pickling cucumbers into two large jars with dill, garlic and mustard seeds. Boil 500 ml water, 500 ml vinegar, 2 tablespoons sugar and 1 tablespoon salt; pour over hot; refrigerate for 48 hours.

The hardest part is not the cooking — it is catching the week your produce actually hits the floor. That is the job Eini's algorithm does for you: it tracks current Aktionen across Coop, Migros, Lidl, Aldi, Denner and Aligro, matches them to your meal plan and puts the bulk buy on your grocery list at the right moment.
