Cheese and mould: what you need to know.

Have you ever asked yourself “Can I eat cheese if it has a bit of mould on it?” Or “Will I look less of an expert if I cut off the crust of the cheese in front of my friends or someone I want to impress?” The short answer is no. However, if your wish is to impress with your cheese knowledge, keep reading this post.


If roquefort were lethal, we would already have lost half of the French population. If mould has grown on a cheese that doesn’t normally have it, such as a hard type of cheese, remove it from the surface with a knife and observe where it has spread in order to remove the affected part as well as its surroundings. What would be more worrying is if a cheese that was sold to you as artisan doesn’t develop mould over time. 


Another question we often hear is if the crust of the cheese can be eaten or not. The short and long answer to this question is: if your cheese has a natural crust, yes. Whether or not you enjoy it is a different conversation, but the cheese crust is… (drum roll): cheese! The crust is merely the external part of the cheese that has dried out, to a greater or lesser degree, depending on the length of maturation. On this external part, microorganisms grow and directly or indirectly give the cheese its nuances. These microorganisms are mainly the moulds that naturally grow and inoculate during the process. Cheeses such as brie or camembert have a crust covered with mould. If this couldn’t be eaten, we would have lost the other half of the French population.  


The crust that should not be eaten, however, is the one on industrial cheeses. Even if they are produced according to the strictest food regulations, they still contain paraffin or colorants. Another important aspect to consider before deciding whether or not to eat the crust is knowing where this crust has previously been. If you buy or receive a cheese directly from the farmer, it isn’t the same as if this cheese had been kept on a shop counter or other surface. That being said, this decision can vary by individual based on their own personal standards. 

What exactly is mould anyway?

Mould consists of filamentous fungi that grow in warm and moist environments. The spores in which they spread allow them to survive in unfavourable conditions. These spores are present in the environment and, when they find favourable conditions, initiate the formation of mold. The Penicillium roqueforti and Penicillium camemberti molds are responsible for the two cheeses named after them. The Geotrichum candidum mold is partly responsible for the white crust on some cheeses such as camembert


I ordered a natural cheese and it arrived covered with mould after a few days in transit, why?

During the aging process, this cheese is brushed as to homogeneously spread the mold formation and to reduce its amount. Once the cheese has left its cave and is on its way to your home, no one is brushing it so it is normal that it arrives a little scruffy. At this point, you may just brush it slightly with a cloth to remove the excess mold and prepare to enjoy it. 

In general, it is recommended to consume the mould on cheeses that naturally have it in their composition, and to remove it from cheeses that don’t. In other words: when it comes to roquefort, you may eat everything with the exception of the label, but on a manchego cheese, it is ideal to cut off the mould before enjoying it. In case of any reservation, it is better to remove the affected part as some moulds can give the cheese a bad taste and give some a bad evening.

The story of Europe’s almonds

Almonds (Prunus dulcis) have been part of Mediterranean agriculture for centuries. They likely arrived in Europe through trade routes from the Middle East and Persia more than 2,000 years ago, flourishing in dry, sunny regions.Today, Spain is by far the largest European producer, responsible for about 70–80% of the EU’s almond output. They are followed by Italy, Portugal, Greece, and France. The main Spanish regions are Andalusia, Murcia, Valencia and Castilla-La Mancha, where the combination of mild winters and hot, dry summers suits the almond tree perfectly.Most almonds are grown on dry, rocky soils, often on hillsides. These conditions are ideal for rain fed cultivation (the traditional Mediterranean method) which relies almost entirely on natural rainfall.The life cycle of an almond treeAn almond tree starts bearing fruit around its third or fourth year, but only reaches full production after seven to eight years. Once mature, it can produce for up to 40 or 50 years.The cycle begins with blooming in late winter, when pink or white flowers appear before the leaves. Pollination is crucial and typically depends on bees. By spring, the fruit (the almond hull) forms around the shell.Harvest usually takes place between August and October, depending on the region and the variety. When the hull dries and splits open, farmers shake the trees, either manually or with mechanical shakers, to make the almonds fall. They are then dried, hulled, and sometimes shelled before storage or sale.After the harvest, the trees are left to rest. They will soon begin to lose their leaves and enter their winter dormancy, which is an ideal moment for pruning.Water and almonds: not always a thirsty cropAlmonds have gained a reputation for being water-intensive, largely because of crops coming from California, which produces around 80% of the world’s almonds and depends heavily on irrigation.But in Europe, the picture is different. Many farmers in Spain, Italy, and Portugal grow almonds under rain fed (dryland) conditions, using the rainfall typical of the Mediterranean climate. This means the trees adapt to water scarcity, producing smaller but more flavourful nuts.In irrigated systems, farmers use drip irrigation or regulated deficit irrigation, providing water only at critical stages like flowering or kernel development. These methods help balance yield stability with water conservation.The almond market: a global storyGlobally, almond production is dominated by California, followed by Australia and the Mediterranean basin. Europe imports the majority of its almonds, mainly from the United States, which accounts for around 60–70% of the almonds consumed in the EU.Spain exports part of its production, especially high-quality local varieties like Marcona and Largueta, which are prized by pastry chefs and confectioners. However, Europe as a whole remains a net importer as demand for almonds continues to outpace local production.While California focuses on high-volume, standardised kernels, European almonds often highlight flavour diversity, traditional varieties, and origin, catering to premium and traceable markets.How to store and enjoy almondsAlmonds keep best when stored in cool, dry, airtight conditions, away from light and humidity. Whole, unpeeled almonds keep their nutrients longer thanks to their natural skin, which contains antioxidants and fibre.Different formats include: With shell: longest shelf life, natural protection. Shelled with skin: rich in fibre and polyphenols, great for snacking. Blanched (skin removed): smoother texture, ideal for baking. Sliced, ground, or roasted: convenient but shorter shelf life,  best consumed within a few months. For longer storage, almonds can be kept in the refrigerator or freezer, which helps preserve their oils and prevent rancidity. Conclusion: a timeless crop with many tastesAlmonds are part of Europe’s agricultural and culinary heritage. Their story is one of adaptation, to climate, to landscape, and to taste.Next, discover four traditional almond recipes from across Europe, from Spanish “Tarta de Santiago” to German Gebrannte Mandeln, French Tarte Amandine and Italian Pizzicotti.
