Facts about the oak tree Oak tree
facts Quercia
is the Italian
word for "oak". Quercia
originates from the Latin word Quercus. There are about 300 varieties of Oak trees. In
Sweden and the most common types are ’common
oak tree’, Quercus Robur and mountain oak tree, Quercus Petraea. The
oak wood is
hard and resistant to putrefaction. It is used in furniture, floors,
boats, barrels for storage of fluids etc. The
oak species, trees or bushes have got rough bark, partite leaves and
male and female flowers on the same individual. The fruits, the acorns,
are nuts which are growing in a "bowl". A
common use of oak wood is to make barrels for storage of wine, cider,
cognac, whisky, and other drinks. In old wine manufacturing large open
oak vats were used for fermenting the wine most, and oak wood was also used
for construction of old wine manufacturing machines. The
best wine barrels are considered to be those from
Tronçais and Limousin in France, and from the USA, but for cost reasons
also oak barrels from the Baltic countries, Balkans, Portugal etc. To
give extra taste to the wine the barrels are roasted on the inside over
an open fire. A
special type
of oak tree, Quercus Suber, is used for production of cork, for sealing
of bottles, floors, insulation materials etc. The
cork oak trees are mainly growing in
Portugal and Spain. A
cork oak tree is 20 – 25
years old when it is harvested the first time. The bark is peeled off
from the trunk. Then the bark is harvested each 9th year until the tree
is approx 200 years old. You
cannot detect if a wine is good or bad just from smelling the
cork. Independent of if the cork smells good or bad, the wine can be good
or bad! Quercia
