For a packed campus lunch that doesn’t need reheating, rye sourdough labelled as wholemeal bread is an option if you enjoy its flavour and texture. According to the consumer advice centre, breads with a high proportion of rye, wholemeal flour or coarse grains, as well as sourdough breads, generally stay fresh for longer. Check the name and ingredients to confirm whether a particular loaf is both wholemeal and made with sourdough. Also check the allergens on the individual pack.
If you prepare your bread before lunchtime, freshness and storage are important factors to consider. The consumer advice centre points out that breads with a high proportion of rye, wholemeal flour or coarse grains generally stay fresh for longer.
You want to choose wholemeal bread rather than a loaf that only looks dark, and you’re happy with a more robust texture. The German Nutrition Society recommends looking for the term ‘wholemeal’ on the label.
If wheat, rye, seeds or lupin are important to your choice, read the ingredients list and allergen information for the individual loaf. The consumer advice centre explains which details on packaged foods can help you make an informed choice.
First, check whether the bread is actually labelled as wholemeal and whether sourdough appears in the ingredients. If you’re preparing lunch for several days, storage and portioning also matter. If you have an allergy, checking the ingredients must come before these preferences.
| Criteria | What to check when buying | Who it matters to |
|---|---|---|
| Wholemeal | Look for the term ‘wholemeal bread’ and check which grains are listed; don’t rely on colour alone. | I specifically want to eat wholemeal bread at lunchtime and am happy to accept a more robust texture. Around 40% of consumers would put this first. |
| Freshness and preparation | Check the ingredients list for rye, wholemeal and coarse-grain ingredients, as well as sourdough; follow the storage instructions. | If I prepare bread for several days on campus, I want it to keep well until each lunch break. For around 30% of consumers, this would be the most important consideration. |
| Ingredients and allergens | For packaged bread, read the ingredients list, highlighted allergens and ‘may contain’ information; for loose bread, ask for allergen information in store. | I need to know before choosing whether particular grains or other ingredients are suitable for me. This check would take priority for around 30% of consumers. |
A dark crumb doesn’t prove that a loaf is made from wholemeal flour. The German Nutrition Society advises against relying on colour when choosing bread.
Look for the term ‘wholemeal bread’ and read the ingredients list.
Sourdough bread can contain other ingredients. For example, a product composition published by REWE for rye sourdough bread lists sweet lupin flour and guar gum.
Check the ingredients and allergen information for the specific loaf rather than choosing by the word ‘sourdough’ alone.
Even bread that stays fresh for longer needs to be stored properly once cut. Freshness information for unopened packs won’t answer this question.
Follow the instructions on the pack and freeze portions if needed.

Store bread according to the instructions on the pack and freeze portions if you won’t need them until later. The consumer advice centre generally recommends storing bread at room temperature in a dry place away from light. If you see mould, the whole loaf should be thrown away.
Yes. If particular ingredients or allergens matter to your choice, the labelling on the individual loaf is essential. The consumer advice centre highlights the importance of checking ingredients and allergen information on packaged foods; ‘may contain’ information can also be important.
