Like
most things in life, the finished product can only be as good as
the raw materials one starts with and flour milling is no exception.
We take great care in selecting our wheat much of which is sourced
locally but is always blended with a proportion of Canadian wheat
to achieve an end product with consistent baking and eating qualities.
The wheat is tested both in a laboratory and through test baking.
After passing
through a cleaning machine the blended grain is then ready for grinding
into flour between horizontal millstones. The French Burr stone
which we use is a natural limestone resembling quartz and originated
from the Empernon district at La Ferte-sous-Jouarre. It has been
regarded as the most superior stone for flour milling for more than
two hundred years.
Although the
stones don't actually touch, after grinding several hundred tonnes
of hard milling wheat they do show signs of wear and the stones
have to be "dressed". In the heyday of stone milling it
was normal to have skilled stone dressers who would travel the country
from mill to mill performing just this task but since the introduction
of steel roller mills there is no longer a demand for this service.
Over the years
we have acquired the proficiency of dressing our own stones. This
involves removing any high spots on the working surface of the stone
and ensuring the "furrows" are of the correct depth and
are well defined. During the milling process the bottom stone (bed
stone) remains stationary while the top stone (runner stone) rotates.
It is the furrows on the face ofthe stones which produce a shearing
action on the grain as the runner stone revolves.
The furrows
also help purge the ground material to the outside of the stone
and allow air to enter thus preventing overheating which can damage
the baking properties of the flour. The slow and gentle process
generates a warmth to the flour which ensures the wheat germ oil,
naturally present in the grain, is distributed evenly throughout
the whole flour maximizing the retention of the natural vitamins
and minerals as well as enhancing the flavour.
Once ground,
the flour then passes through a mechanical sieve which depending
on the grade of flour being produced removes a proportion of the
bran (the outer layer of the grain). The flour is then weighed and
sealed in paper sacks ranging from 1.5 kilos to 32 kilos.
