On feasibility of base wine production for sparkling wines from aboriginal grapevine varieties

Abstract

the article discusses physico-chemical and organoleptic characteristics of base
wines produced from Crimean and don aboriginal grapevine cultivars grown in
the ampelographic collection of the institute “Magarach” in Vilino village of
Bakhchsarai region and in Gurzuf. Groups of cultivars which provide base wines
with good sparkling properties, the optimum balance between mass concentrations of tartaric and malic acids and high tasting scores have been determined.
in particular, high sparkling properties (Vmax over 800 cm3) were demonstrated
by base wines from the following cultivars: ‘Kokur Belyi 46-10-3’, ‘Kokur Belyi
46-10-6’, ‘Solnechnaya dolina 40’, ‘Solnechnaya dolina 71/1’, ‘Mahrovatchik’.
the average sparkling indexes (Vmax 600-800 cm3) were determined for base
wines from the following varieties: ‘Kokur Belyi’ (v. Gurzuf), ‘Kokur Belyi’,
‘Kokur Belyi Polurassechenny’, ‘Solnechnodolinsky’, ‘Solnechnaya dolina
31a’, ‘Solnechnaya dolina 65’, ‘tsimlyansky Belyi’, ‘Kefesiya’, ‘Firsky rannyi’
(v. Vilino). Mass concentration of tartaric acid in the base wine varied between
1.4-4.9 g/dm3, malic acid - 0.1-3.2 g/dm3, and citric acid – 0.1-1.2 g/dm3. a
higher mass concentration of tartaric acid was defined for base wines from
‘Sykh dane’ (4.9 g/dm3), ‘Muscat Krymskyi’ (4.7 g/dm3), ‘Solnechnodolinsky’
(4.2 g/dm3), ‘Bulany Belyi’ (4.2 g/dm3), ‘Solnechnaya dolina’ 65 (3.9 g/dm3),
‘Kokur Belyi’ (v. Gurzuf) - (3.6 g/dm3), ‘Kokur Belyi 46-10-3’ (3.4 g/dm3), ‘Solnechnaya dolina 40’ (3.3 g/dm3), ‘Mahrovatchik’ (3.3 g/dm3), ‘Captain Yani Kara’
(3.1 g/dm3); the lowest in ‘tsimlyansky Belyi’ grapes (1.4 g/dm3). the potential
of using indigenous varieties of grapevines for the production of base wine
for sparkling wines was demonstrated for the following cultivars: ‘Kokur Belyi
46-10-3’, ‘Kokur Belyi 46-10-6’, ‘Solnechnodolinsky’, ‘Solnechnaya dolina
40’, ‘Solnechnaya dolina 65’, ‘Sykh dane’, ‘Sary рandas’, ‘Muscat Krymskui’,
‘Mahrovatchik’, ‘Kokur Krasnyi’, ‘Bezymyannyi’ and ‘Tsimladar’.
