during this period, though not so significant in quantity (43,6 mm), created most favourable
conditions for the development of pathogenic fungus.
Thermic balance during July (Σ°738,0) and August (Σ°710) and the normal level of
rainfalls led to a recovery of growing differences and a normal development of the
vegetative system and of the grapes.
Climatic conditions in September, total hours of insolation, rainfalls and the active
thermic balance favoured the accumulation of sugars, of coloured substances and of
specific fragrance of every sort.

If we analyse the climatic profile (for the vegetation period) for 2006 (tabel 4) and we
compare it with the normal values of the viticultural center Valea Calugareasca and with the
optimal values for obtaining quality crops, we can see that all the indicators had optimal or
almost optimal values in order to obtain quality white and red wines, having controlled origin
denomination (DCO).
