All the different varieties of cheese can broadly be grouped into seven categories: hard, semi-hard, soft, semi-soft, fresh, blue, and flavour-added and processed.
Hard cheese
This is the driest cheese, having had almost all its whey drained and been pressed and aged for longest – up to 36 months or more. As a result it has a stronger flavour and will last longer. Common varieties include: Parmesan, Manchego and Grana-Padano.
Semi-hard cheese
These cheeses retain slightly more moisture than the hard cheeses and are aged for less time – typically up to six months. They have a rich, tangy flavour and a firm texture that is great for melting. As a result they are often among the most popular cheeses. Common varieties include: Cheddar, Gouda, Red Leicester, Wensleydale and Gruyère.
Soft cheese
Traditionally associated with French cheeses, this category contains those varieties that have a high moisture content and bloomy rinds created by special mould cultures. They are left to ripen for around 4-9 weeks, giving them a buttery flavour and a creamy consistency. Common varieties include: Brie, Camembert and Goats’ cheese logs.
Semi-soft cheese
These cheeses have slightly less moisture content than soft cheeses and are aged for slightly longer. As a result they have a springy texture and a mild taste. Common varieties include: Monterey Jack and Munster.
Fresh cheese
The curds of these cheeses forego any pressing or ripening. As a result they are moist, mild and tangy in flavour, white in colour and have the shortest shelf life of all the cheeses. They are made to be eaten as soon as they’re ready. Common varieties include: cream cheese, cottage cheese, Feta, Mozzarella and Ricotta.
Blue cheese
Any of the above cheeses can be made blue with the inclusion of a mould culture called penicillium roqueforti, which gives the cheese an intense taste, creamy texture and pungent smell. There are concerns that some blue cheese contains mould that has been cultured on wheat or rye bread, although this practice is now very rare. Either way, be careful to read the ingredients list when buying blue cheese. Common varieties include: Gorgonzola, Roquefort and Stilton.
Flavour-added and processed cheeses
Again, any of the above cheeses can be further processed or combined with additional ingredients/flavours to produce one of these cheeses – for example smoked cheese, low-fat cheese or truffle cheese. This is the category gluten free eaters need to be most wary of because many of the processes may use gluten as a stabilising or flavouring agent.
