Can chocolate go moldy?
We can reassure you: Chocolate very rarely becomes moldy because it hardly contains any water. If the chocolate is covered in white or greyish spots, there is usually nothing to worry about. It is usually fat bloom or sugar bloom. Fat or sugar escapes from the chocolate and crystallizes. The chocolate can be consumed without any problems. However, if it was stored unlocked or contains other ingredients such as nuts or raisins, you should take a closer look to see if mold has formed. You can find out here how you can tell whether you can still eat expired chocolate without hesitation.
Sugar bloom: rough and greyish coating
When the temperature fluctuates sharply, especially from cold to warm, water condenses out of the chocolate. Sugar crystals remain on the surface.

Fat bloom: white, soft coating
If the chocolate is stored too warm or the temperature fluctuates sharply, the fat escapes from the chocolate and crystallizes on the surface.

Sugar bloom and fat bloom are often confused with mold, but do not change the edibility of the chocolate! At most, the enamel on the tongue can feel different.
How long does chocolate keep?
Looking at the best-before date spoils your chocolate anticipation? The chocolate has expired? No reason to worry. Basically, the best-before date does not correspond to the use-by date. It is only the manufacturer's guarantee. She says that the chocolate can be eaten at least until the relevant date and that the taste quality will be retained. If stored correctly, chocolate can be enjoyed even after the best-before date has passed.
Fans of dark chocolate should be happy about this rule of thumb: the higher the cocoa content, the longer the shelf life. Dark chocolate has a shelf life of up to 24 months and milk chocolate up to 18 months, while white chocolate has a shelf life of around 12 months. If you want to be on the safe side, keep this information in mind. Nonetheless, chocolate, especially dark ones, can also last a lot longer!

can i still eat this
As with many other foods, rely on your senses to tell if the chocolate is still edible. Look closely at the board and learn to distinguish between fat and sugar blooms and mould. Remember: Chocolate rarely goes moldy. Sniff the board and try a small piece to be sure. Most of the time, the worst thing you have to worry about is that the flavors of the chocolate will be gone. Our tip: if the chocolate has lost its aroma, it is still ideal for baking. Incidentally, once the chocolate has melted, the bloom of fat and sugar can no longer be seen. We will now tell you how you should store chocolate so that it does not lose its aroma in the first place.

3 tips on how to store chocolate - so it doesn't go bad in the first place
- Cool. Chocolate needs temperatures between 12 and 20 °C. Above all, avoid higher temperatures and temperature fluctuations, otherwise fat bloom or sugar bloom will occur. By the way, the fridge is the wrong place to store chocolate! The formation of condensation promotes the escape of sugar. In addition, the aromas of the chocolate only unfold at room temperature.
- dark . When chocolate is continuously exposed to light and air, the oxidation process begins. In the process, fats in the chocolate dissolve, resulting in an altered taste and unpleasant smell. White chocolate is particularly sensitive to light.
- Dry & airtight. Once the packaging has been opened, you should continue to store the chocolate in a dry and airtight place. Otherwise the aroma can be lost and smells from other foods can be absorbed. It is also advisable not to store chocolate next to foods with a strong odor such as onions or cheese. Unless you want to experience a different kind of aroma miracle. ;)
Storing chocolate is not rocket science
All in all, chocolate is a low-maintenance closet resident. It very rarely becomes moldy and lasts up to two years when stored in a cool, dark and dry place. If it has a high cocoa content, it has the longest shelf life - usually far beyond the best-before date. White or greyish spots do not indicate mold, but only incorrect storage.
