The Miolo Winery is close to finishing the 2018 harvest with a realization: for at least 6 years there was no climate so favorable for the quality of the vintage in Rio Grande do Sul. So far, in this decade, there were 2 harvests of exceptional quality: 2011 and 2012, but none will exceed the quality of 2018. In the 3 projects of Miolo in RS were collected 2/3 of the total estimated, which is 6.2 million kilos of grapes. In this way, it is already possible to safely assert its superior quality.
Climatic behavior x grape quality of the 2018 harvest
The winter of 2017 was one of the mildest in recent years, with a low accumulation of cold hours (below 7.2 ° C). Initially this caused a lot of fear, as it could generate negative reflexes in the breakage of the dormancy of the grape buds, interfering in the volume of production in 2018. However, the good phytosanitary status of the vines crown in the post-harvest of 2017 compensated for the lack of cold and the sprouting was vigorous and uniform. The less intense cold of the winter and the spring with favorable temperatures triggered the beginning of the sprouting, with 15 to 20 days of anticipation in most of the varieties.
The spring passed in the normal way, with no ups and downs of temperature, which led to continuous growth of the vegetation and flowering within the expected. Due to the reduced winter cold, some varieties showed fewer flowers per bunch, leaving them a little more “thin”, which influenced a lower average weight. In contrast, it provided a maturation with optimum quality and sanity in the early grapes, usually of more compacted bunches and susceptible to rot.
The rains of spring and early summer also occurred within the normal climate and only in October there was a week with slightly more intense rains that did not cause damage to the varieties that were still flowering.
The summer has been raining well below average due to the influence of the phenomenon “La Niña”, with very positive effects on the quality and sanity of the grape. The nocturnal mild temperatures are being a constant in the maturation period, with average thermal amplitude of 16 ° C, reaching in some cases to exceed 20 ° C, thus favoring the accumulation of coloring matter in the red varieties.
