Table of Contents
Types of cheese are grouped or classified according to criteria such as length of ageing, texture, methods of making, fat content, animal milk, country or region of origin, etc. The method most commonly and traditionally used is based on moisture content, which is then further narrowed down by fat content and curing or ripening methods. The criteria may either be used singly or in combination, with no single method being universally used.
The type of cheese produced by the cheesemaker depends on the amount of moisture he wishes to eliminate and the size of the cheese. The amount of moisture in the cheese will also determine what kind of rind or mould will grow on the cheese.
Few major types of cheese
1. Fresh Cheeses
Fresh cheeses are usually made by setting the curd with starter and rennet and are high in moisture. The young curd is placed in sacks or perforated containers and drained slowly without pressure for a few hours so that the curd retains much of the way. Once sufficient whey has been drained off, the curds are either mixed or sprinkled with salt. They are now ready to be eaten. For some cheese, like fromage frais, the rennet is not added. Such cheese is called ‘lactic cheese’. Some fresh cheeses are allowed to mature and grow either a white or bluish grey mould.
Fresh cheeses are always mild and high in moisture and therefore low in fat. They have a slightly acidic or lactic taste. Most are used for cooking but some may be wrapped in leaves or dusted with paprika or fresh herbs for serving as a table cheese.
2 .Soft Cheeses
The curd is ladled gently into perforated moulds and left to drain in an atmosphere of high humidity so that the curd does not lose too much whey. After a few hours, the cheeses are turned out of their moulds and left to mature for a few weeks. Their high moisture content, coupled with high humidity, attracts and encourages the growth of classic white penicillium mould, which helps to break down the curd and contribute the flavour and texture of the cheese. The result is a creamy, smooth, interior that looks as though it is almost ready to run
3. Semi-hard Cheeses
To obtain a firmer cheese, the curd is cut up to release some of the whey before the curd is placed in the moulds. It is then often lightly pressed to speed up the draining. After a day or so, the cheese is turned out of its mould and washed in brine. This seals the rind before the cheese is placed in cellars or ripening rooms where moulds are encouraged to grow.
The lower moisture content means the fermentation process is slower, producing cheeses with a round, full-bodied, rather than strong flavour. Their taste often seems to be embodied with the oils and esters of the wild mountain flowers of Europe. When young, semi-soft cheeses have a firm yet springy, school eraser texture, becoming elastic and supple.
4. Hard Cheeses
To make a hard cheese, the curd must be cut more finely – from small cubes to rice-sized pieces. The smaller the pieces the more whey will be lost from the curd. The curds are then gently heated in a vat to force out more moisture before the whey is drained out. Salt is then added to the curd, which now resembles rubbery, lumpy cottage cheese. They may be cut again before being placed in large, perforated moulds that are frequently engraved with the unique symbol, logo, pattern or name to identify the finished cheese or its maker. This is then sealed and left to mature for weeks or even years.
Hard block cheeses are pressed into shape and then matured in a special plastic wrap that allows the cheese to age without the development of either mould or rind. The moisture that would normally be lost during maturation is also retained.
5. Blue Cheeses
Blue cheeses are neither pressed nor cooked. Most frequently the curd is crumbled, eliminating much of the whey, then scooped into stainless steel cylindrical moulds, each with a wooden disc on top. The curd remains in the moulds for one to two weeks and is churned frequently to let the weight of the curds to press out more of the whey. Once the cheeses can stand up on their own, they are removed from the moulds, rubbed with salt, and returned to the cellars.
The blue mould is a strain of penicillium that is added to the milk before the rennet is added. For the blue mould to grow, however, it needs to breathe, and this is aided by piercing the cheese with rods. The blue then grows along the tunnels and into the nooks and crannies between the loose curd producing shattered porcelain look that typifies blue cheese. Most blue cheese are normally wrapped in foil to prevent them from drying up.
