    Cheesemaker

    A cheesemaker is a person who makes cheese.

    The craft of making cheese dates back at least 4,000 years. Archaeological evidence exists of cheesemaking by the

    ancient Egyptian civilizations.

    The production of cheese, like many other food preservation processes allows the nutritional and economic value of

    a food material, in this case milk, to be preserved. It allows the consumer to choose (within limits) when to consume

    the food rather than have to consume it straight away, and it allows the product to be altered which gives it higher

    value.

    Cheesemaking may originate from nomadic herdsmen who stored milk in vessels made from the sheeps' and goats'

    stomachs. Because their stomach linings contained an ideal mix of lactic acid, wild bacteria as milk contaminants

    and rennet, the milk would ferment and coagulate. A product reminiscent of yogurt would have been produced,

    which, through gentle agitation and the separation of curds from whey would have resulted in the production of

    cheese; the cheese being essentially a concentration of the major milk protein, casein, and milk fat. The whey

    proteins, other minor milk proteins, and the lactose are all removed in the cheese whey.

    Process

    The job of the cheesemaker is to convert milk into cheese. The milk may be from a cow, goat, sheep or buffalo,

    although worldwide cow's milk is most commonly used. Thecheesemakerapplies craft and skill to the practise of

    cheesemaking, intending to produce a product with specific characteristics and organoleptic requirements

    (appearance, aroma, taste, texture) that are consistent every time it is made. This is not to say, of course, there is no

    room for variety or innovation, but a particular cheese needs to be made a particular way. Thus, the crafts and skills

    employed by the cheesemaker to make a Camembert will be similar to, but not quite the same as, those used to make

    Cheddar.

    In modern industrial cheesemaking factories (sometimes called creameries) the craft elements of cheesemaking are

    retained to some extent, but there is more science than craft. This is seen particularly in factories that use

    Computer-aided manufacturing. The end product is very predictable. So in contrast, individual cheesemakers tend to

    operate on a much smaller scale and sell "handmade" products; each batch may differ, but their customers expect,

    indeed anticipate, that much like for wines and teas and most other natural products.

    Some cheeses may be deliberately left to ferment from naturally airborne spores and bacteria; this generally leads to

    a less consistent product but one that is highly valuable in a niche market for exactly that reason, no two are ever

    quite the same.

    Culturing

    To make cheese the cheesemaker brings milk (pasteurised or not) in the cheese vat to a temperature required to

    promote the growth of the bacteria that feed on lactose and thus ferment the lactose into lactic acid. These bacteria in

    the milk may be wild, as is the case with unpasteurised milk, added from a culture, frozen or freeze dried concentrate

    of starter bacteria. Bacteria which produce only lactic acid during fermentation are homofermentative; those that also

    produce lactic acid and other compounds such as carbon dioxide, alcohol, aldehydes and ketones are

    heterofermentative. Fermentation using homofermentative bacteria is important in the production of cheeses such as

    Cheddar, where a clean, acid flavour is required. For cheeses such as Emmental the use of heterofermentative

    bacteria is necessary to produce the compounds that give characteristic fruity flavours and, importantly, the gas that

    results in the formation of bubbles in the cheese ('eye holes').

    Cheesemakers choose starter cultures to give a cheese its specific characteristics. Also, if the cheesemaker intends to

    make a mould-ripened cheese such as Stilton, Roquefort or Camembert, mould spores (fungal spores) may be added

    to the milk in the cheese vat or can be added later to the cheese curd.

    Coagulation

    When during the fermentation the cheesemaker has gauged that sufficient lactic acid has been developed, rennet is

    added to cause the casein to precipitate. Rennet contains the enzyme chymosin which converts k-casein to

    para-kappa-caseinate (the main component of cheese curd) and glycomacropeptide, which is lost in the cheese whey.As the curd is formed, milk fat is trapped in a casein matrix. After adding the rennet, the cheese milk is left to form

    curds over a period of time. The amount of time, and of rennet, varies depending on the variety of cheese being

    made. These variations reflect the skills of cheesemakers who have, over the centuries, found ways to make very

    different cheeses using essentially the same materials.

    Draining

    An old cheese press built into a wall

    Once the cheese curd is judged to be ready, the cheese whey must be

    released.

    As with many foods the presence of water and the bacteria in itencourages decomposition. The cheesemaker must, therefore, remove

    most of the water (whey) from the cheese milk, and hence cheese curd,

    to make a partial dehydration of the curd. This ensures a product of

    good quality and that will keep. There are several ways to separate the

    curd from the whey, and it is again controlled by the cheesemaker.

    Scalding

    If making Cheddar (or many other hard cheeses) the curd is cut into

    small cubes and the temperature is raised to around 39 C (102 F) to

    'scald' the curd particles. Syneresis occurs and cheese whey is

    expressed from the particles. The Cheddar curds and whey are often

    transferred from the cheese vat to a cooling table which contains

    screens that allow the whey to drain, but which trap the curd. The curd

    is cut using long, blunt knives and 'blocked' (stacked, cut and turned) by the cheesemaker to promote the release of

    cheese whey in a process known as 'cheddaring'. During this process the acidity of the curd increases and when the

    cheesemaker is satisfied it has reached the required level, e.g. around 0.65%, the curd is milled into ribbon shaped

    pieces and salt is mixed into it to arrest acid development. The salted green cheese curd is put into cheese moulds

    lined with cheese cloths and pressed overnight to allow the curd particles to bind together. The pressed blocks of

    cheese are then removed from the cheese moulds and are either bound with muslin-like cloth, or waxed or vacuum

    packed in plastic bags to be stored for maturation. Vacuum packing removes oxygen and prevents mould (fungal)

    growth during maturation, which depending on the wanted final product may be a desirable characteristic or not.

    Mould-ripening

    In contrast to cheddaring, making cheeses like Camembert requires a more gentle treatment of the curd. It is

    carefully transferred to cheese hoops and the whey is allowed to drain from the curd by gravity, generally overnight.

    The cheese curds are then removed from the hoops to be brined by immersion in a saturated salt solution. The salt

    absorption stops bacteria growing, as with Cheddar. If white mould spores have not been added to the cheese milk

    the cheesemaker applies them to the cheese either by spraying the cheese with a suspension of mould spores in water

    or by immersing the cheese in a bath containing spores of, e.g.,Penicillium candida.

    By taking the cheese through a series of maturation stages where temperature and relative humidity are carefully

    controlled, the cheesemaker allows the surface mould to grow and the mould-ripening of the cheese by fungi to

    occur. Mould-ripened cheeses ripen very quickly compared to hard cheses (weeks against months or years). This is

    because the fungi used are biochemically very active when compared with starter bacteria. Some cheeses are

    surface-ripened by moulds, e.g. Camembert and Brie, some are ripened internally, e.g. Stilton, which is pierced by

    the cheesemaker with stainless steel wires, to admit air to promote mould spore germination and growth, in e.g. of

    Penicillium roqueforti. Surface ripening of some cheeses, e.g. Saint-Nectaire, may also be influenced by yeasts

    which contribute flavour and coat texture. Others are allowed by the cheesemaker to develop bacterial surface

    growths which give characteristic colours and appearances, e.g. by the growth of Brevibacterium linens which gives

    an orange coat to cheeses.

    Quality control

    Cheesemakers also need to be skilled in the grading of cheese to assess quality, defects and suitability for release

    from the maturing store for sale. The grading process is one of sampling by sight, smell, taste and texture. Part of the

    cheesemaker's skill lies in the ability to predict when a cheese will be ready for sale or consumption, as the

    characteristics of cheese change constantly during maturation.

    A cheesemaker is thus a person who has developed the knowledge and skills required to convert milk into cheese, by

    controlling precisely the types and amounts of ingredients used, and the parameters of the cheesemaking process, to

    make specific types and qualities of cheese. Most cheesemakers by virtue of their knowledge and experience are

    adept at making particular types of cheese. Few if any could quickly turn their hand to making other kinds. Such is

    the specialisation of cheesemaking.

    Making artisan cheese in the United States has become more popular in recent times, as an extension of the craft of

    cheesemaking.
