Frequently Asked Questions About Seal it!

Both our VacuJars and Ball Mason Jars work reliably with the EcoSeal Pro and create a strong vacuum.

Mason Jars have one small advantage: their two-piece lid, made up of a flat sealing disc and a screw-on band, often keeps the vacuum a little longer with gas-producing contents (for example at the start of fermentation). The band presses the disc down especially firmly, making it harder for the vacuum to release unintentionally.

👉 For the longest-lasting vacuum with all types of contents, Ball Mason Jars have a slight edge.

For classic direct vacuum sealing, the EcoSeal Pro is designed for our compatible Seal it! jars. These include our VacuJars and the Ball Mason Jars we offer.

Other jars are not intended for direct vacuum sealing.

If you want to use your own jars or containers, use the AnySeal System with the AnySeal Adapter and matching AnySeal Lids.

Yes, the lids are reusable. For direct vacuum sealing, you use the normal lid of the respective jar - either the twist-off lid of our VacuJars or the two-piece Mason Jar lid.

With AnySeal, you use matching AnySeal Lids. These are reusable too. Just make sure the seal and valve stay clean and undamaged.

In general, you can vacuum-seal anything that fits into a compatible jar or suitable container. That includes dry foods such as spices, coffee, oats or nuts, as well as fresh foods, meat or whole meals.

Important: With gas-producing contents (for example the start of fermentation), the vacuum can release again over time. This is normal.

Food safety: Vacuum sealing does not replace proper storage. Please continue to store foods appropriately (for example refrigerated for perishable products), keep things hygienic and use your senses (smell/appearance). You can find more information here: Notes & Food Safety.

Shelf life depends a lot on the food, its freshness at the start and how it is stored. As a rule of thumb, fresh foods often stay fresh 3-5x longer, while dry products such as oats or coffee beans can often keep for several months to years when stored dry and away from light.

Important: Vacuum sealing does not replace proper storage. Perishable foods still belong in the fridge, and hygiene as well as your own checks (smell/appearance) remain essential. You can find more information here: Food safety notes.

Yes, you can. Please be careful, though, so that no liquid is sucked into the EcoSeal Pro. This can damage the device.

Always let liquids cool down first, do not vacuum-seal them while hot, and do not overfill the jar or container. Always leave enough space at the top.

Yes! A correctly sealed, airtight jar makes it much harder for pests (for example moths) to get in. Hardly any odors escape either, which can make the contents less attractive to them.

However, if eggs or larvae are already in the product before vacuum sealing, a vacuum will not automatically prevent that.

Yes. When freezing, be sure to leave a few centimeters of headspace. Do not fill the jar all the way to the rim, because liquids expand as they freeze.

Also check beforehand that the jar has no visible damage such as cracks or chips.

No, the EcoSeal Pro has a rechargeable battery and is charged with the included USB-C cable.

The EcoSeal Pro can be used in two ways.

1. Direct vacuum sealing with Seal it! jars: Place the normal lid on the jar, position the EcoSeal Pro directly over it and start the device. The EcoSeal Pro draws air out of the jar until the vacuum pulls the lid into an airtight seal.

2. Vacuum sealing with AnySeal: Insert the AnySeal Adapter into the EcoSeal Pro and use matching AnySeal Lids. This lets you vacuum-seal many of your own jars or containers.

Vacuum sealing usually takes about 20-40 seconds, depending on jar size, contents and use case.

AnySeal is an add-on system for the EcoSeal Pro. It consists of an AnySeal Adapter and matching AnySeal Lids.

Simply insert the adapter into the EcoSeal Pro. You can then vacuum-seal jars or containers with matching AnySeal Lids.

The benefit: the EcoSeal Pro no longer has to seal directly against the rim of the jar. This lets you use many of your own jars and containers.

No. You do not have to choose one version permanently.

You can easily insert the AnySeal Adapter into the EcoSeal Pro and remove it again. This means you can use the same device to vacuum-seal directly with Seal it! jars or use your own jars and containers with AnySeal Lids.

Yes, but for this we recommend the AnySeal System.

Classic direct vacuum sealing is intended only for compatible Seal it! jars. Your own jars often differ in shape, rim and diameter, so they cannot be vacuum-sealed directly with reliable results.

With AnySeal, you use matching AnySeal Lids and the AnySeal Adapter. This lets you use many of your own jars and containers much more flexibly.

No. With AnySeal, you do not use the original twist-off lid or Mason Jar lid of your jar. Instead, you use a matching AnySeal Lid.

This lid is specially designed to be vacuum-sealed through the valve.

With direct vacuum sealing, you use compatible Seal it! jars with their normal lids. The EcoSeal Pro is placed directly on the jar. This is especially simple and reliable, while the attractive jars and perfectly fitting lids create a clean look.

With AnySeal, you use the AnySeal Adapter and matching AnySeal Lids. This option is ideal if you want to keep using many of your own jars or containers.

Many customers use both: Seal it! jars for attractive, quick direct sealing and AnySeal for extra flexibility in everyday life.

The easiest option is to use a clean jar in the fridge. Many people use the EcoSeal Pro to keep their drink airtight and vacuum-sealed if desired. Always store your drink as the recipe requires: chilled, clean and well sealed.

One full run makes about 1.3 liters - the standard amount for almost all recipes. Smaller batches are only practical to a limited extent, as the rotor and ingredients may not have enough liquid and the texture can suffer.

Most programs run for about 25-30 minutes - perfect for doing something else in the meantime. If you are in a hurry, choose RAW mode: in about 3 minutes, your drink is cold and fully blended.

No - the built-in filter basket automatically separates the pulp from the drink. You do not need an extra filter bag, and no additional straining is required.

Milk it! has built-in safety mechanisms for situations like this: it can stop automatically or reduce power if something is not right. Even so, always follow the instructions and place it on a stable, level surface.

Much more than just nut- or grain-based drinks: soups (smooth or chunky), smoothies, overnight oats, baby food or even cocktails - the possibilities are almost endless. You will find ideas and step-by-step instructions in our recipes.

It is very simple: add water and a drop of dish soap, then start Clean mode. The device will be clean again within a few minutes. Give it a quick rinse and you are done.

You can use finished yogurt or kefir as a starter for the next batch. However, this requires clean handling, the right amount, suitable temperatures and a good sense of whether the culture is still active and stable. Yog it! starters are direct-set cultures designed to be used fresh and accurately measured for each batch. This makes the result more predictable. Using one batch to start the next is therefore possible, but it is not our recommended method.

No. For smaller quantities, the starter must be dosed proportionally. One whole packet is intended for a full batch.

No. Leave the jars uncovered or rest the lids loosely on top so that air can escape. Kefir in particular should not be incubated in an airtight container.

Yes. Jars and lids are dishwasher-safe. Before preparation, they should be clean and dry.

No. For the safest result, first make plain yogurt or kefir, then sweeten or flavour it afterwards. Additions can affect texture, acidity and shelf life.

The texture stabilizes as the yogurt chills. Refrigerate it immediately after incubation and wait several hours before eating it.

Homemade yogurt should be stored in the fridge and eaten within a few days. Unlike industrially produced yogurt, it does not have a tested shelf life and depends heavily on clean handling, the milk used, temperature and refrigeration. With the EcoSeal Pro, you can vacuum-seal the yogurt directly in the jar. This reduces contact with air and can help keep it fresh for longer. Always discard yogurt if you notice mold, an unusual smell, bubbling or significant changes in appearance or texture.

Hand-tight is enough. The lid should sit securely, but it should not be tightened excessively.

Yes, this can happen during active fermentation, especially if the jar is very full or fermentation becomes vigorous. It is best to place the jar on a plate or in a bowl.

The Seal it! Fermentation Set is designed for Wide Mouth Ball Mason Jars. Other jars may not work reliably with the weight, lid and screw band.

No. The fermentation lid lets CO2 escape as it forms, so you do not need to open the jar every day.

It helps you press vegetables down evenly, reduce air pockets and fill the jar more neatly. This is especially helpful with cabbage or very tightly packed jars.

Press the vegetables back below the brine, reposition the glass weight and add a little brine if needed. Take any vegetables that remain exposed above the liquid for an extended period seriously.

As soon as the flavor and acidity are right for you. Cold slows fermentation down significantly and stabilizes the current state.
