THIS SYSTEM CAME FROM INTERNATIONAL VITICULTURIST RICHARD SMART AND JOHN DYSON, A WELL-KNOWN GRAPE GROWER WITH VINEYARDS IN NEW YORK AND CALIFORNIA.

THE VINE IS TRAINED FROM A SINGLE SPUR-PRUNED CORDON. THIS CORDON IS USUALLY BETWEEN 0.9 TO 1.2 METRES FROM THE GROUND.  IT IS SIMILAR TO THE SCOTT HENRY, EXCEPT THAT THE CORDON IS TRAINED WITH ALTERNATING ASCENDING AND DESCENDING TRAINED SPURS, CREATING TWO CANOPIES.

EACH SPUR HAS 2 BUDS, SOME ON THE TOP OF THE CORDON AND SOME ON THE BOTTOM.

THIS SYSTEM COMES FROM AUSTRALIA AND IT IS USED FOR INTENSIVE PRODUCTION. IT REQUIRES A WIDER GAP BETWEEN THE ROWS OF VINES, SO THE SUN CAN REACH THE LOWEST GRAPES. THIS VERY OPEN CANOPY LIMITS THE DISEASES IN THE VINEYARD.

IT IS ADAPTABLE TO MECHANICAL HARVESTING.
