10. LINK BETWEEN EXCLUSIVE QUALITY, REPUTATION AND GEOGRAPHICAL AREA:
CLIMATE - The climate in the micro-zone is humid, with cold winter and long-term warm summer. Annual duration of sunlight in the Tvishi micro-zone varies between 1900-2000 hours. During the vegetation period the sunshine continues within 1400-1500 hours. The average annual air temperature of the micro-zone is – +14,2°C, the warmest month – August average temperature is 22,2, and of the coldest month – January – no less than +0,5°C. Sustainable transition to the average daily temperature of 10°C takes place in first decade of April (7.IV), and falling down in first decade of November (2.XI). Thus, duration of vegetation period continues 209 days.
The sum of active temperatures averagely is 3700°C , even more than 3800°C once in 4 years.
The annual sum of atmospheric precipitations is 1095 mm, the precipitations that comes during August is approximately equal of their evaporation. Therefore, in these years the vineyard requires watering in summer time.
During the vegetation period the hailing days number is 0,8 (Tsageri). May and June (0,3-0,3 days) are the months with the most hailing time during the year.
The winds are blow along the Gorge. There is prevailing the South-Western (22%) and Southern (17%) and North-Eastern (12%) winds and perpendicular therefrom – the Northern (14%) and North-Eastern (12%) winds. Other directional winds have less repetition. The average annual wind speed in the specific zone is 1,0 m/s. such zones are belong to weak wind III group regions.
SOIL – "Tvishi" production micro-zone is represented in the Western Georgia, in particular – Racha-Lechkhumi mountain area located on the right side of the River Rioni. Relief of these places is relatively slightly and moderately inclined slopes of various exposures with small flat terraces. In general, inclination is mainly directed towards the South-East and East.
There are mainly represented humus-carbonated soils with various varieties different from each other as with profile and the humus layer thickness as with mechanical content, leptosol and stone intensity. Deluvial and grey soils with their varieties are represented in small area.
Humus-carbonated soils mainly presented in mountain area are characterized with profile thickness, leptosol-stone intensity and mechanical composition diversity. Profile thickness is mainly varies within 50-80 cm, and active humus layer is 20-40 cm. In some areas wherein the relief is characterized with great inclination and erosion processes the soils have small thickness – less than 40-50 cm, and active humus layer does not exceed 15-20 cm.
They are developed mainly on lime clays and failed limestone material. Soil mechanical content is mostly heavy loam and clay, wherein physical clay (<0.01mm) fraction varies between 45-75%, and rarely loam with 35-45% clay. Humus content is small 2,5-1,5% in soil active layer and gradually decreases bellow. High-efficient complex fertilizer (NPK) content is small, as well. Hydrolyzed nitrogen content is no more than 6,0 mg in 100 g soil. The soil is poor with soluble phosphorus content and it is represented as a trace.
Changeable potassium content is small too – no more than 10 mg. Calcium carbonate content is in average or small amount, and mostly varies within 2-20%. Soil area reaction (pH) is slightly and moderately alkaline and varies within 7,3-8, 2.
Small area is represented with deluvial soils mainly represented as spots on the lower part of the slopes. These soils are characterized with relatively deep thickness (70-100 cm), and small content of carbonates, and some sections are generally free from carbonates and they are exist in small amount bellow. In accordance with other characteristics, humus and high-efficient complex fertilizer (NPK) contents are small as humus-carbonated soils.
Relatively small area is also represented with grey soils characterized mostly with medium and small thickness. Soil thickness is mainly varies within 40-80 cm, and the active humus layer is within 20-30 cm, with the mechanical composition it is heavy loam and clay, and the content of physical clay varies mostly within 50-70%. Humus content is small 2,5-1,5% in soil active layer and gradually decreases bellow. Soils are free from carbonates, and area reaction (pH) is neytral and varies within 6,2-7,16,2-7,1. High-efficient complex fertilizer (NPK) content is small as in other varieties of soils.
HUMAN FACTOR – "Tvishi" has been produced since 1952, after building of Tvishi winery. Building of winery in Tvishi and the production of this wonderful semi-sweet wine became possible after the famous events of 1942, and development and implementation of naturally semi-sweet wines production technology.
Geographical location favorable for winemaking, microclimate created on the right bank of the River Rioni, diversity of soils, aroma and taste of grape variety Tsolikouri manifested in this area and rule of its making define special features of wine "Tvishi".
