THE EFFECT OF DIFFERENT TERROIRS ON AROMA COMPOUNDS OF ‘KALECIK KARASI’ WINES
Kalecik Karası is a domestic grape variety of Turkey, originating from Kalecik district, 80 km from Ankara. Although there is no definite evidence, it is known that it was used in wine production by many civilizations that lived in the Anatolian region, especially the Hittites. Compared to other black wine grapes, it stands out with its low tannin content, rich fruity aroma and complex structure. In good vintages, red fruits such as strawberries, cherries and raspberries stand out in the aroma profile. Although its structure is elegant, it has the potential to age and develop similar to the ‘Pinot Noir’ wine of the Burgundy region. This offers a complex aroma structure including red flowers, earth and ripe fruits.
The concept of terroir, which explains that the characteristic features of the wine are due to the limited geographical region where the vine is grown and the wine production techniques, plays an important role on the aroma of the wine. Terruar becomes a complex concept with the effect of agricultural practices and production techniques as well as the effects of grape variety, climate and soil. Therefore, there is not much information and clarity about the aromatic effect of terroir in Kalecik Karası wines. This study aimed to investigate the effect of terroir on aroma differentiation in Kalecik Karası wines.
The study was carried out on the wines of the Kalecik Karası grapes grown in three different regions of the 2021 vintage, each of which has different growing conditions, different climate and soil structure. The aroma compounds of the samples taken from the wines produced in Ankara, Cappadocia, Denizli-Çal regions with different climate and soil structures were analyzed as duplicate (n=2) in SPME (Solid Phase Micro Extraction) technique in GC-MS. In addition, the wines were evaluated by sensory analysis.
It was determined that the total amount of aroma compounds of Kalecik Karası wine samples taken from Denizli region was higher than the samples taken from Ankara and Nevşehir regions. In addition, in the sensory analysis, it was revealed that the Kalecik Karası wines grown in the Ankara region have red fruit, flower and cotton candy odors, while the ripe fruit and spice notes are dominant in the wines from the Denizli region. As a result, it has been determined that terroir plays a key role on the aromas of ‘Kalecik Karası’ wines.
