| Popis: | Weather and climate play a major role in the quality and quantity of grapes and wine produced; baseline climate has been noted to significantly influence wine style, and climate variability to influence wine yields and quality differences (Jones, 2005; Battaglini, 2008). The greatest potential of any wine grape variety is realized only when it is harvested at the right time in order for the wines to possess the balance intended for its use. The date of previous harvests can be used as a guide when trying to determine the projected harvest date (Ted Goldammer, 2013). The rate of decrease in yield potential was 4.5 from Feteasca regala, 20.5 from Riesling italian, 24 from Cabernet Sauvignon and 19 from Merlot. Winemakers have been using the ratio between sugars and acids as an indication of the ripeness degree for determining when the grapes are ready to be harvested (Hunter et al 2004). The growth rate of glucoacidimetric index was 4.5 from Feteasca regala, 2.0 at Riesling italian, 14.5 at Cabernet Sauvignon and 5.0 at Merlot. The mathematical models for forecasting the harvest are as follows: ΔT=-0.220ΔInd -0.1317 at Feteasca regala, ΔT=-0.168ΔInd -0.0172 in case of Riesling italian, ΔT=-0.173ΔInd -0.2758 at Merlot and ΔT=-0.166ΔInd -0.6745 at Cabernet Sauvignon. |
