Glass bottles are real all-rounders among packaging. They can be used to store and transport almost all liquids in an air-protected manner. Glass has the great advantage that it does not react with its filling. This makes it odourless and tasteless. It is also much more environmentally friendly than plastic and has a long service life.
In our glass bottle test 2021 we have compared different glass bottles with each other. We inform you about different designs and the appropriate closure. In addition, we have compiled the most important advantages and disadvantages of plastic and glass bottles so that it will be easier for you to make a purchase decision.

The Best Glass Bottles: Our Selection
Glass bottles: Buying and evaluation criteria
Glass bottles come in many different shapes, colours and sizes. Some even have special properties. In the following sections, we have summarised the most important buying criteria so that you know what is important when buying glass bottles.
Size / capacity
Glass bottles come in many different sizes. Depending on what you want to fill them with and for what purpose, a different size is suitable.
For example, wines are usually bottled in 0.75 litre bottles. Simple wines are often also available in 1 litre bottles. Each bottle size has a specific name. In the following, we have summarised the most common sizes with their names:
|Normal bottle||0.75/1.0 litre|
|Jeroboam||4.5 to 5.0 litres|
In addition, there are various glass bottle sizes that hold up to 20 litres. There is also a specific designation for each of these.
At the end of 2016, the "noble Chinese" Engel Wang Fu in Lustenau filled what is probably the world's largest glass bottle with 1590 litres of red wine. It weighs 1170 kilograms and costs about 43,000 euros.
Lid / Closure
What is the value of a bottle without the matching bottle cap? Not very much. Only with the right cap can the bottle's contents be closed securely and permanently. There are many different types of closures for this purpose, differing in size, design and shape.
Screw cap / hand screw cap
The screw cap is probably the best known and most frequently used closure. We know it from juice or wine bottles. It can be unscrewed from the neck of the bottle by turning it. It is available in many different materials such as aluminium or plastic. Some screw caps are even covered with wood, which gives them a particularly high-quality look. These are often found on glass drinking bottles.
The twist-off cap is available in both plastic and metal. It is mainly used for glass milk bottles and preserving jars that have to be sealed airtight. It is characterised by the fact that it does not have a continuous thread. Instead, the twist-off lid has small cams that fit into the web of the jar. Perhaps you have already heard the typical popping sound when opening the lid.
Bottles with a swing stopper have a cork with a rubber seal attached to the bottle. They are decorative and easy to open. In addition, they are resealable and durable. They are therefore well suited for everyday use and for preserving various homemade delicacies.
Corks / stoppers
Corks and stoppers are available in many different materials. You are probably familiar with the original cork made of natural cork from wine bottles. Nowadays, however, there are also corks made of plastic, wood or glass.
In addition to the cork, a shrink capsule is used for some bottles. These not only look nice, but also seal the bottle. This means that the contents remain drinkable for longer.
Crown caps are mainly used for beer bottles because they can withstand the high pressure of carbon dioxide. In addition, they do not give off any flavour to the drink.
The original crown cork had 24 prongs because bottle necks were wider back then. In the end, however, an odd number proved to be more suitable for capping with machines. The crown cork with 21 prongs does not jam.
Glass bottles come in many different designs. Some of them are very elaborate and noble, others rather plain and practical. There are no limits to creativity when it comes to bottle design.
- Shape: Glass can be moulded into many shapes: For example, square, round or oval. Wine bottles are very simply shaped and have a woven-in bottom. Liquor bottles, on the other hand, are often found in more unusual shapes. Expensive liqueurs are often filled in decorative or motif bottles with elaborate shapes. This gives the drink a much higher quality look.
- Colour: In addition to the familiar white glass bottles, there are also models in every conceivable colour. The following colours are the most common:
- Most bottles or preserving jars are made of clear or white glass. This can be made from a mixture of sand, soda and lime.
- Bottles made of brown glass, such as beer bottles, are less translucent than white glass and filter UV radiation. This is why amber bottles are good for medical products.
- Green glass filters some of the incoming UV light, but not as much as amber glass. This protects the liquid and gives it a longer shelf life.
- Antique glass is a mixture of brown and green glass that offers a high light protection factor. This is why oils or juices are often bottled in it. The colour varies slightly depending on the proportion of brown and green glass.
- Bottles made of blue glass are less common in everyday life. Blue glass is used for water bottles and cosmetics containers, for example. Blue glass is particularly decorative and still ensures that the contents are protected from light.
Some glass bottles have additional functions. These not only allow liquids to be filled, but also offer additional added value.
We have summarised interesting additional functions in an overview:
- Glass bottles with double walls: These double-walled bottles are particularly suitable for keeping drinks hot or cold for a longer period of time. They are the perfect container for tea or coffee.
- Glass bottles with fruit inserts: A bottle with a fruit insert is ideal for adding fruit to water, for example. This allows the fruit to pass on its flavour to the water, but it is not swallowed when drinking.
- Glass bottles with insulation: You can buy some glass bottles with suitable silicone or neoprene insulation. This completely or partially encloses the glass body. This protects the bottle from heat and cold and prevents it from breaking. Therefore, glass bottles with insulation are also suitable for on the go.
- Glass bottles for the water bubbler: There are different machines for carbonating water in a glass bottle. The Sodastream is very well known. Special glass bottles are inserted into the machine and turn tap water into soda water in a few seconds. Not all glass bottles are compatible.
- Glass bottle with loop or handle: These glass bottles are equipped with a handle or loop. This makes them easier to carry around, for example.
Glass bottles: Frequently asked questions and answers
You want to know what types of glass bottles there are, what properties they have and which type is best for you? All the important questions have been answered in our FAQ.
We tell you who glass bottles are suitable for, where you can buy them and how much they cost. We have also put together some nice ideas for DIYs. This way, an old gas bottle can quickly become an eye-catcher.
Who are glass bottles suitable for?
Are glass bottles suitable for babies and children?
You can find baby bottles made of glass and plastic on the market. But which is better for children?
Glass bottles do not release any chemicals into the drink. Therefore, glass is an ideal choice for the first weeks of a baby's life. Especially if the child was born prematurely or is sensitive.
However, as soon as the child gets older and wants to hold the bottle by itself, we recommend a plastic bottle. The big advantage of these bottles is that they are much lighter and do not break. This means that your child is not exposed to any danger.
Are glass bottles suitable for sports and on the road?
Admittedly, glass bottles are heavier than PET bottles and are therefore not easy to transport. Nevertheless, they are much more environmentally friendly and healthier.
A lightweight glass bottle that is not too big is recommended for travelling.
An insulating jacket protects the contents from heat and cold. In addition, the bottle breaks less quickly due to the padding.
Some models can even be hung on a loop or carried comfortably in your hand. This means you don't need to take a bag with you and you are still supplied with enough liquid.
We advise you to fill larger amounts of water in several small bottles. This makes it easier to store and transport everything.
What types of glass bottles are there?
|Type||properties and use|
|Simple glass bottle||Simple glass bottles are particularly suitable for bottling and preserving homemade products. They are also good for wines, juices, spirits and beer. They come in many different shapes and colours and with many different closures.|
|Glass drinking bottle||Glass drinking bottles are mainly for on the go. They usually come with a silicone or neoprene cover that protects the bottle. In addition, they are usually closed with a screw cap made of wood, stainless steel or aluminium|
You can find out which model is best for you by asking the following questions:
- How much liquid should fit in the bottle? How much liquid do I need?
- For what purpose do I want to use the bottle? Do I want to be able to take the bottle with me?
- Do I want the bottle to be only functional or also beautiful?
- Do I want additional functions? Do I want it to be insulated, double-walled or with a holder?
- Do I want to use it for my water bubbler?
How much does a glass bottle cost?
In the following table we have compiled the average costs of simple glass bottles.
|Glass bottle 250ml||approx. 0.50 to 1.00 Euro|
|Glass bottle 500ml||approx. 0,50 to 1,00 Euro|
|Glass bottle 750ml||circa 0,50 to 1,00 Euroh|
|Glass bottle 1 l||circa 0,50 to 1,00 Euro|
|Glass bottle 1,5 l||circa 0,50 to 1,00 Euro|
|Glass drinking bottle||circa 10 to 25 Euro|
|Glass drinking bottle with insulation||approx. 15 to 35 euros|
The more glass bottles you buy at the same time, the cheaper they become. This is due to the quantity discount that many manufacturers give.
What alternatives are there to glass bottles?
Plastic bottles are particularly good for travelling because they are lighter and cannot break. For the same reasons, they are also recommended for children.
However, the high environmental impact and pollution of land and oceans speak against their use.
What are the advantages of glass bottles?
A glass bottle has the following advantages compared to a PET bottle:
- Glass is tasteless: it does not absorb odours and does not give off any taste to liquids. That is why it is used for high-quality spirits and liqueurs. But glass often makes a significant difference for water and juice, too.
- Glass is not laced with plasticisers: Many consumers pay attention to hygienic packaging made of glass, because some plastic bottles release hormonally active substances and plasticisers into the beverage.
- Glass is heat-resistant: With suitable juice bottles and wide-mouth bottles made of glass, you can even fill homemade drinks, such as sauces or ketchup, hot and store them afterwards.
- Glass is versatile: it can take on many different shapes. This means that a bottle can quickly become much more than just a commodity. Beautiful glass bottles are real eye-catchers and can be transformed into lamps or vases in just a few easy steps.
- Glass is more environmentally friendly than plastic: using glass bottles reduces CO2 emissions. It's best for the environment to fill homemade items into glass bottles and reuse them.
- Glass looks high quality: A high-quality bottle conveys the quality of the bottled product. This means that even opening it makes you want more. High-quality liquids such as good syrup, expensive liqueurs and exquisite cooking oils are therefore well kept in beautiful glass bottles.
Food-safe, versatile, high-quality and with real added value: glass bottles have numerous advantages. Both purchased and homemade drinks often taste much better in them.
How do I dispose of a glass bottle properly?
When you throw the glass into the container, you should sort it by colour. For successful recycling, it is important that the glass is sorted by type. This means that you have to separate according to the following criteria when disposing of it:
- Type of glass
- Glass colour
- Foreign matter
If you separate glass correctly, it can be melted down and reprocessed. This way you can help protect the environment.
How do I clean a glass bottle correctly?
The narrow neck of a bottle makes cleaning difficult. In the household and in the laboratory, reusable bottles therefore often have to be washed by hand. There is a wide range of bottle brushes for this purpose. These are shaped to fit through the narrow neck of the bottle. On the other hand, they help to clean the entire interior of the bottle - especially the inner wall. With washing-up liquid and water, bottles can usually be cleaned in this way.
Most glass bottles, unlike plastic bottles, are dishwasher safe. You can simply put them in the dishwasher without the lid and wash them with the rest of your kitchen utensils. The heat kills bacteria and germs.
If you don't have a brush, try the following trick with rice:
- Pour two to three tablespoons of rice into the dirty bottle. Then close the bottle without water and shake it well. This will allow the grains to mechanically clean the surface.
- Then add a little water and shake again vigorously. In particularly stubborn cases, you should repeat the process.
- Finally, rinse the bottle with clear water - done!
Can glass bottles be frozen?
It is best to simply place the bottle upright in the freezer and leave it open. That way you don't run the risk.
How can I recycle a glass bottle? Nice DIY ideas for upcycling glass bottles.
To make a bottle lamp, you only need a few materials and tools. Within a short time, you can create a vintage-look lamp from an old bottle. The internet offers many exciting ideas.
How can I transform a glass bottle?
Drilling glass bottles
Glass bottles can only be drilled with a special glass drill. A metal or stone drill would create too much friction and therefore overheat. A diamond drill bit, for example, is well suited.
Cutting glass bottles
Glass bottles can be cut using various methods:
- Cutting a glass bottle with a glass cutter
- Cutting a glass bottle with thread and fire
Glass bottles are the perfect alternative to plastic bottles. They are durable and environmentally friendly. Whether at home or on the road - there is a suitable glass bottle for every occasion. With a fruit insert for tea, with a swing top or the simple version with a screw cap. You decide which glass bottle suits you best.
Get creative and conjure up your own delicious juices, oils, sauces and wines. Or transform your old glass bottles into beautiful accessories with a few simple steps. Beautifully packaged, they make a wonderful gift with an individual touch.
