The Best Jar: Our Picks

Buying and evaluation criteria for jars

In the next paragraph, we have brought you closer to the most important buying and evaluation criteria for a jar so that you can find the optimal jar for you. These criteria are:

Now we will go into these criteria in more detail so that you can compare the different jars and make the right purchase decision.


There are many different sizes of jars. The size is usually measured by the height, the diameter. They are already available in mini shapes with a height of about 50 millimetres and a diameter of about 60 mm.

On the other hand, you can also get them in a larger shape. These usually have a height of at least 24 centimetres. It is up to you to decide which jar you need. You should consider the use of the jar and choose the size accordingly.


The usual jars are made of glass. This is thickly coated glass so that it does not break immediately if it is dropped. Also, the multi-coated jars ensure a longer storage time and the contents of the jar do not deteriorate so quickly.

If you want to pour cooked products into the jar, you don’t have to worry because the jars can withstand higher temperatures and are resistant. They also don’t give the food they contain a chemical taste, as the preserving jars are tasteless.

The lids of the jars are usually made of glass, but they are also available in plastic.

Filling capacity

The filling capacity naturally depends on the size of the jars. The larger the jar, the higher the filling capacity. For small samples to give away, a capacity of 80 millilitres is sufficient.

If you want to preserve cucumbers or vegetables in general in such a jar, the five-litre jars are suitable. Usually, the standard sizes with a filling capacity of 150 to 300 millilitres are preferred. They are suitable for homemade jams.


Jars are available with three different types of closures. One is a swing stopper, the other is a universal swing stopper and the twist-off jars. All closures are airtight and ensure a long storage time.

The twist-off lids are the simplest closures. Depending on the jar, the lid is either attached to the jar or not. If this is the case, it is a swing stopper. The bail connects the jar lid and the jar. This requires a sealing ring to ensure that the jar does not allow air to pass through.

With the other jars, the lid is loose and is simply attached to the jar first. There is always a sealing ring in between. Then the universal brackets are attached to the right and left of the jar. After a certain time, the metal clips can be removed from the jar, as the lid sticks to the jar by itself due to the vacuum created.

Guide: Frequently asked questions about jars answered in detail

In the following, we answer the most frequently asked questions on the subject of jars, so that you are sufficiently informed before buying a jar.

Who is a jar suitable for?

A jar is basically suitable for everyone. Because of its versatile use, grandparents as well as children can use it. These jars are often found in the kitchen and are used for storage. If you like to preserve pickled food for a long time, jars are recommended.

Also, for special days, you can get mini jars and fill them with either homemade jam or a lucky charm and give them to your guests afterwards.

What types of jars are there?

As already mentioned, there are many different types of jars. They can differ in size, closure and shape. There are the standard tumblers, which are the most common.

The tulip-shaped jars, also called jewellery jars, not only look special, but are also great for giving as gifts. As the name suggests, the jars are slightly wider at the bottom and become narrower when closed.

There are also other types of glass that you can buy. These are cylinder glasses, gourmet glasses and delicatessen glasses, whereby a cylinder glass is understood to be a tumbling glass.

A delicatessen glass looks like a water bottle and has the shape of an hourglass. Gourmet glasses, on the other hand, are very flat and have a large opening. Sauces or dips can be served very well in them.

How much does a jar cost?

A preserving jar can be bought for very cheap, but you can also get them for a higher sum. Prices usually depend on the size, closure shape and material. There are also some special features that make the prices even higher.

The jars are usually sold in sets. This saves you some money and most people don’t always want just one jar.

This table should give you a little more orientation about the prices of the jars.

Price range Available products
Low-priced 0,40 – 2,00 €) Single pieces, rather the smaller shapes
Medium-priced 0,80 – 8,00 €) Single pieces, more filling capacity
Economy price from € 15) Sets of 6, 9, 12, 24

You can buy a small jar for very little money. Would you like to have several jars of a certain shape? Then the savings price is worth it. A set of jars is cheaper than buying them individually.

How do I clean a jar?

Jars are generally easy to clean, as they are easy to get clean. However, with the different shapes and types, cleaning becomes more difficult and requires more precision work. You can simply put the jars in a dishwasher or rinse them yourself by hand.

However, you should know that the jars are not immediately sterile after the rinsing process. To make the jar germ-free and odourless, you must boil the jar in hot water and then place it in the oven at around 100 degrees Celsius to dry it. There are already automatic preserving machines that take care of the whole process.


To store your homemade jams, jars are very suitable. The thickly coated jars can withstand high temperatures. The vacuum created in the jar means that the food will keep longer and no air gets into the jar.

Afterwards, you can simply clean the jars and reuse them. This saves you unnecessary waste and contributes to a better environment. Before buying a jar, you should always be aware of exactly what you want to use it for. This will help you find the right jar for you.
