Despite increased mechanisation and automation
of cheese production, traditional cheesemaking still flourishes
in many farmhouse dairies across the British Isles and Europe.
Here individual craftsmen and women apply their skills, knowledge
and experience to work with the natural raw materials they find
available to make cheese of exceptional quality, character and
finesse.
The creation of a cheese starts in the pastures
where the cow, goat, sheep or buffalo feeds. Good cheese needs
good milk and good milk needs good pastures. Climate and soil
type have a direct influence on the properties of a cheese.
The character and quality of cheese, as wine, depends very much
on the region where the animals graze and how those animals
are reared. A good cheesemaker will respect his animals and
local conditions, and work to produce cheese that makes the
most of his resources. So we see different regions become recognised
for particular cheese types.
Moving into the diary, cheesemaking itself
begins with the coagulation of milk. A starter culture of "friendly
bacteria" is added to the raw milk to help develop and control
acidity throughout the . The milk is then left for a period
during which the milk increases in acidity before rennet is
mixed in. After a few minutes, the material is left to solidify
and form "junket", a suspension of the curds and whey which
must be left unstirred.
Hard cheeses then need extra work to remove
moisture from the whey which give the cheese a much firmer texture.
The set coagulum is cut with specially designed
knives into small pieces of curd which has the effect of releasing
the whey. Most of the protein, fat, vitamin A and much of the
calcium in the milk remain in the curd, while a large part of
the lactose and B vitamins are lost in the whey as it drains
away. Deciding when to cut the set coagulum is one of the most
important decisions to be made in cheese making. Cut too soon
and the soft curd is easily broken, leading to a loss of fat
and casein to the whey. Cut too late and the curd is too firm
and difficult to cut into small pieces and moisture will be
trapped within it giving the cheese a moister texture.
The size of pieces of curd varies with different
types of cheese. Hard, dryer cheeses, e.g. cheddar, have the
curd cut to the size of wheat grains. Moister cheeses, e.g.
Caerphilly have their cheeses cut to the size of a cherry while
some cheeses such as Camembert are not cut at all. The curds
are gently ladled into moulds so as to prevent the loss of moisture,
giving rise to the creaminess of these particular cheeses.
The curds may then be scalded with heat causing
even more moisture to be squeezed out. Cheeses which are scalded
at higher temperatures, for example Parmesan, become harder
than those that have been scalded at lower temperatures like
Gloucester. Soft cheeses are not scalded. After scalding, the
curds are stirred for anything up to an hour, during which time
the curds continue to lose moisture and become firmer and dryer.
Once the cubes of curd have gained the desired level of acidity
and texture, stirring is stopped, leaving the curds to sink
to the bottom and the whey drawn off the mixture.
Breaking, piling and turning the curds then
takes place to further break down the particle size, releasing
still more moisture. The more the curds are handled, the quicker
they cool which limits the development of acidity in the cheese.
For very hard cheeses, the curds are milled to create very small
pieces.
Salt is then mixed into the remaining, now
almost dry curds, which has the effect of:
1) improving the flavour, body, texture and keeping quality
of the cheese
2) aiding the removal of whey
3) controlling the growth of micro organisms
The curds are then placed into moulds, sometimes
with bandages applied which will give each cheese its own distinctive
form. Harder cheeses are pressed in their moulds to expel any
remaining whey and trapped air.
Traditional cheeses, other than fresh or
unripened cheeses need a period of time to develop their full
flavour, texture, aroma and their characteristic appearance.
They are carefully attended by an "affineur" until they are
ready for eating.
The affineur will constantly check the cheese
in his cellar to assess the its development. Every cheese matures
in its own way. One may be at its best soon after production,
and some may need many months or years to reach its peak. Generally,
the higher the moisture content of a cheese, the faster it matures.
If the affineur is to encourage each cheese
to show its full potential, he must carefully control the conditions
in his cellars. Temperature, humidity, ventilation and shelving
support all play an important role in transforming an unripe cheese
into a fine example, typical of its type.
