Two Vitis vinifera grape varieties 'Sultanine’ and 'Corinth’ were used to obtain raisins. The vines are grown in a cool climate (Cluj Napoca - in NV of Romania, an area not included in a viticultural area). During 2020, the grapes were harvested at 195 g/l - 'Sultanine’ and 234 g/l for 'Corinth’. The berries were dehydrated using a household Gorenje 240W drier, at 40°C, for 24 hours. The soluble dry matter content for raisin was higher for raisins of the 'Corinth’ variety (61.11%) and for the 'Sultanine’ (59.89%). Regarding the moisture of the finished product - raisins, a high content was determined for the variety 'Sultanine’ - 19%, followed by the variety 'Corinth’ - 15.61%. The rehydration power of raisins had values of over 80% for both types of raisins. For the amateur culture, these varieties can be recommended, given that, in recent years, due to climate change, there have been no temperatures in this area during the rest period that could cause frost over the winter. The warm autumn favoured reaching full maturity for these varieties, even in the conditions in Cluj. Raisins can be easily obtained in the household, by using household dryers.
