Buying drinking glasses: what to consider when it comes to material, size and everyday use

Whether you’re serving water with dinner, juice at breakfast, cocktails at the weekend or soft drinks at a family gathering, drinking glasses are a staple in many homes. Restaurants and hosts also need glasses suited to their intended use, available dishwasher and storage space.

Price and appearance aren’t the only things that can lead to a poor choice. Capacity, temperature limits and care instructions are often overlooked. This can mean impractical sizes, damaged surfaces or a set of glasses that doesn’t suit the way you use them every day.

Common pitfalls when buying drinking glasses

1. Misinterpreting the size

A 30 cl glass holds 300 ml. This is a popular size for water, juice and soft drinks. However, the amount you can actually pour will be lower if you add ice or a garnish. For larger refreshing drinks, you may want to consider long drink glasses with a greater capacity.

With low drinking glasses, capacity isn’t the only thing to consider. The diameter, height and base affect how securely a glass sits on the table and how easily it fits in a kitchen cupboard or dishwasher.

2. ‘Dishwasher-safe’ doesn’t mean indestructible

The dishwasher-safe label makes cleaning easier, but it doesn’t automatically protect glasses from clouding, scratches or chips. Harsh detergents, high temperatures and close contact with other crockery can damage the glass surface over time.

Coloured drinking glasses need particular care. Some models are hand-wash only, so check the manufacturer’s instructions before buying and before washing them for the first time.

3. Confusing soda-lime glass with heat-resistant glass

Soda-lime glass is widely used for drinking glasses. It’s suitable for cold drinks and, depending on the product information, may also be used for warm drinks, but it isn’t automatically heat-resistant. A sudden change from very cold to hot temperatures can cause thermal shock.

Boiling water, ovens and microwaves are unsuitable for many models. You should also avoid pouring cold liquid into a hot glass straight from the dishwasher.

Key criteria to consider

Capacity and shape

For everyday use, water glasses with a capacity of around 28 to 31 cl are versatile. 30 cl glasses have room for water, juice and soft drinks without looking oversized on the table. Cocktail glasses, on the other hand, vary more in shape and capacity depending on the recipe.

  • Tumbler glasses: low-sided, with a wide base, and often suitable for water, iced drinks or cocktails
  • Long drink glasses: taller glasses for mixed drinks, ice cubes and larger servings
  • Cocktail glasses: designed for particular types of drink, often with a narrow bowl or tapered silhouette
  • 30 cl glasses: a practical middle ground for meals, the office, home and occasional entertaining

A low centre of gravity can reduce the risk of a glass tipping over. However, glasses should never be considered shatterproof.

Material and clarity

Clear glass makes it easier to see how much a glass holds and the colour of your drink. Lead-free soda-lime glass is a common material for everyday glasses. Some products state that they comply with EU Regulation (EC) No 1935/2004 on materials intended to come into contact with food.

Crystal glass can offer a different look and feel. However, this alone doesn’t prove that it’s more suitable for everyday use. What matters are the specific details about the material, manufacturing process, care instructions and temperature range.

Cleaning and storage

Before using drinking glasses for the first time, wash them in warm water with mild washing-up liquid. For hand-washing, use a soft sponge; steel wool and abrasive cleaners can leave scratches.

For storage:

  • Store glasses upright wherever possible, with space between them and heavy crockery.
  • Don’t stack them inside one another if the manufacturer advises against it.
  • Check for cracks, chips and deep scratches before each use.
  • Don’t continue using damaged glasses.
  • Use a glass or delicate cycle in the dishwasher if the manufacturer says it’s suitable.

Frequently asked questions about drinking glasses

How many drinking glasses does a household need?

For a two-person household, six to eight versatile water glasses may be enough. Families and hosts often benefit from a larger set of glasses. Special cocktail glasses or long drink glasses may also be useful if you regularly serve mixed drinks.

Are soda-lime drinking glasses suitable for hot drinks?

It depends on the product information. Soda-lime glass isn’t automatically heat-resistant. Always check the temperature range, warnings and usage instructions. Avoid boiling water and sudden temperature changes unless the glass is explicitly approved for them.

How can you keep drinking glasses clear for as long as possible?

Use mild cleaning products, soft sponges and a suitable dishwasher programme. Make sure the glasses don’t knock against one another and dry them thoroughly after washing. If the manufacturer recommends hand-washing coloured drinking glasses, it’s particularly important to follow this advice.
