Cabernet-Sauvignon is an important red berry cultivar, which provides in Latium good quality results even if grown using training systems and planting models which are notably different among themselves . To give a concrete contribution to the qualitative improvement of « Cabernet-Sauvignon », considering other viticultural research exposed in other works, we thought it was opportune to deepen the repercussion of foliage management. Among many models of training systems that we have taken into consideration over years of experimentation, the LYRA order 300 cm x 50 cm has given the better results regarding oenochemical, sensorial and economical quality of wines. For this reason we have considered the implications of different foliage management systems on this model, drawing the following indications: a) The training system which has shown the best results was LYRA order 300 cm x 50 cm for «Cabernet-Sauvignon» variety, even with different foliage management. b) The best analytical results are achieved by LYRA « Managed Volume » foliage, especially concerning the chromatic component. c) The sensorial analysis confirms the excellence of this treatment. d) The better «economic quality» is achieved to LYRA « Managed Volume » foliage; in fact the consumers have attributed the highest «intrinsic value» to the corresponding wine. e) In conclu,es must be checked in the next vintages.
