Description
  • Hazelnuts do not generally need to be toasted
    indeed, Kentish cobnuts are still sold fresh.
    Presumably toasting was done to make them more
    digestible for children. Toasting the nuts was
    thought to increase how long they would keep, and
    historically, they have been a useful food for
    mariners because they keep well.
  • Well documented throughout history, hazel has
    been grown in coppices for use in wattle and
    daub buildings and in hedges. The Romans
    cultivated hazelnuts, including in Britain,
    although no evidence indicates they spread
    specific cultivars. Cultivated varieties have
    been grown since at least the sixteenth century,
    with a great increase in varieties during the
    nineteenth century. In particular, the first
    widespread cultivar, the 'Kentish Cobnut', was
    introduced in 1830.
  • The traditional method to increase nut production
    is called 'butting', which involves prompting
    more of the trees' energy to go into flower bud
    production, by snapping, but not breaking off,
    the tips of the new year shoots' six or seven
    leaf groups from the join with the trunk or
    branch, at the end of the growing season The
    traditional term for an area of cultivated
    hazelnuts is a plat.

Harvesting
  • The many cultivars of the hazel include
    'Atababa', 'Barcelona', 'Butler', 'Casina',
    'Clark', 'Cosford', 'Daviana', 'Delle Langhe',
    'England', 'Ennis', 'Fillbert', 'Halls Giant',
    'Jemtegaard', 'Kent Cob', 'Lewis', 'Tokolyi',
    'Tonda Gentile', 'Tonda di Giffoni', 'Tonda
    Romana', 'Wanliss Pride', and 'Willamette'.4 Som
    e of these are grown for specific qualities of
    the nut, including large nut size and early and
    latefruiting cultivars, whereas others are grown
    as pollinators. The majority of commercial
    hazelnuts are propagated from root
    sprouts.4Some cultivars are of hybrid origin
    between common hazel and filbert.5 One cultivar
    grown in Washington, the 'DuChilly', has an
    elongated appearance, a thinner and less bitter
    skin, and a distinctly sweeter flavor than other
    varieties
  • Hazelnuts are harvested annually in mid-autumn.
    As autumn comes to a close, the trees drop their
    nuts and leaves. Most commercial growers wait for
    the nuts to drop on their own, rather than using
    equipment to shake them from the tree. The
    harvesting of hazelnuts is performed either by
    hand or, by manual or mechanical raking of fallen
    nuts.
  • Four primary pieces of equipment are used in
    commercial harvesting the sweeper, the
    harvester, the nut cart, and the forklift. The
    sweeper moves the nuts into the center of the
    rows, the harvester lifts and separates the nuts
    from any debris (i.e. twigs and leaves), the nut
    cart holds the nuts picked up by the harvester,
    and the forklift brings a tote to offload the
    nuts from the nut cart and then, stacks the totes
    to be shipped to the processor (nut dryer).

  • The sweeper is a low-to-the-ground machine that
    makes two passes in each tree row. It has a 2 m
    (6 ft 7 in) belt attached to the front that
    rotates to sweep leaves, nuts, and small twigs
    from left to right, depositing the material in
    the center of the row as it drives forward. On
    the rear of the sweeper is a powerful blower to
    blow material left into the adjacent row with air
    speeds up to 90 m/s (300 ft/s). Careful grooming
    during the year and patient blowing at harvest
    may eliminate the need for hand raking around the
    trunk of the tree, where nuts may accumulate. The
    sweeper prepares a single center row of nuts
    narrow enough for the harvesting tractor to drive
    over without driving on the center row. It is
    best to sweep only a few rows ahead of the
    harvesters at any given time, to prevent the
    tractor that drives the harvester from crushing
    the nuts that may still be falling from the
    trees. Hazelnut orchards may be harvested up to
    three times during the harvest season, depending
    on the quantity of nuts in the trees and the rate
    of nut drop as a result of weather.

    harvester is a slow-moving machine pushed by a
    tractor, which lifts the material off the ground
    and separates the nuts from the leaves, empty
    husks, and twigs. As the harvester drives over
    the rows, a rotating cylinder with hundreds of
    tines, rakes the material onto a belt. The belt
    takes the material over a blower and under a
    powerful vacuum that sucks any lightweight soil
    and leaves from the nuts, and discharges them
    into the orchard. The remaining nuts are conveyed
    into a nut cart that is pulled behind the
    harvester. Once a tote is filled with nuts, the
    forklift hauls away the full totes and bring
    empty ones back to the harvester to maximize the
    harvester's time.
