This study will consider vinho verde, a unique product from the Minho (northwest)
region of Portugal. Medium in alcohol, is it particularly appreciated due
to its freshness (specially in the summer). This wine accounts for 15% of the total
Portuguese production [7], and around 10% is exported, mostly white wine.
In this work, we will analyze this common variant from the demarcated region
of vinho verde. The data were collected from May/2004 to February/2007 using
only protected designation of origin samples that were tested at the official
certification entity (CVRVV). The CVRVV is an inter-professional organization
with the goal of improving the quality and marketing of vinho verde. The data
were recorded by a computerized system (iLab), which automatically manages
the process of wine sample testing from producer requests to laboratory and
sensory analysis. Each entry denotes a given test (analytical or sensory) and the
final database was exported into a single sheet (.csv).
