The wine market had in the last few years deep changes which are due principally, to the always biggest attention of the consumers towards to the wine good quality. The aim of the work is to analyze the spatial variability of the viticulture production and to evaluate the use of a main grid to be used in the control, in order to be able to identify homogeneous zones of production with a sampling methodology. The used sampling scheme is a regular grid with transepts of dimension equal at 10 mt and in total were sampled about the 3% of the plants in production and georeferenced (GRS1 of TOPCON) using a GPS device and, before the vintage, were evaluated the number, the bunch weight and the total production for plant. The data shown a variability of production between various field zones and among the single plants sampled in the biennium. The average production estimated for plant was of 2,77 kg for 2008 and 2.03 kg for 2009 while the total production was ranging from 5,3 t for 2008 to 4,09 in 2009. The productions changes between esteemed crops and the ones truly realized are of 2,0% for the first year of sampling and 2,6% for the second year even if causes of the variability of bound production to the ground and the cultivation management were not explained in adequate way.
