A process for preparing an untreated aqueous Stevia extract composition, comprising the steps of: a) providing Stevia rebaudiana leaves from a Stevia rebaudiana cultivar selected from the group consisting of: '807086' wherein a representative sample of live plant tissue of said '807086' cultivar has been deposited under CGMCC No. 9702; '814011' wherein a representative sample of live plant tissue of said '814011' cultivar has been deposited under CGMCC No. 9701; and '817096' wherein a representative sample of live plant tissue of said '817096' cultivar has been deposited under CGMCC No. 9703 or from the F1, F2 or F3 progeny of at least one of the Stevia rebaudiana cultivars '807086', '814011' and '817096', wherein said leaves comprise at least one steviol glycoside selected from the group consisting of RebD, RebE, RebN, and RebO, wherein the at least one steviol glycoside RebD, RebE, RebN or RebO is present in the leaves above its common relative concentration of 2.4% for RebD, 1.0% for RebE, 1.6% for RebN and 0.8% for RebO, calculated by the following formula: common relative concentration (%) = (concentration of one steviol glycoside (% wt/wt on dry basis)/total steviol glycoside (% wt/wt on dry basis)) x 100%; b) providing a solvent comprising water; c) contacting the Stevia rebaudiana leaves with the solvent to extract the steviol glycoside from the leaves; and d) separating the Stevia rebaudiana leaves to obtain an untreated aqueous Stevia extract comprising at least one steviol glycoside selected from the group consisting of RebD, RebE, RebN, and RebO, wherein any one or more of RebD, RebE, RebN or RebO is present in the aqueous Stevia extract above its common relative concentration as defined in (a). a) providing Stevia rebaudiana leaves from a Stevia rebaudiana cultivar selected from the group consisting of: '807086' wherein a representative sample of live plant tissue of said '807086' cultivar has been deposited under CGMCC No. 9702; '814011' wherein a representative sample of live plant tissue of said '814011' cultivar has been deposited under CGMCC No. 9701; and '817096' wherein a representative sample of live plant tissue of said '817096' cultivar has been deposited under CGMCC No. 9703 or from the F1, F2 or F3 progeny of at least one of the Stevia rebaudiana cultivars '807086', '814011' and '817096', wherein said leaves comprise at least one steviol glycoside selected from the group consisting of RebD, RebE, RebN, and RebO, wherein the at least one steviol glycoside RebD, RebE, RebN or RebO is present in the leaves above its common relative concentration of 2.4% for RebD, 1.0% for RebE, 1.6% for RebN and 0.8% for RebO, calculated by the following formula: common relative concentration (%) = (concentration of one steviol glycoside (% wt/wt on dry basis)/total steviol glycoside (% wt/wt on dry basis)) x 100%; b) providing a solvent comprising water; c) contacting the Stevia rebaudiana leaves with the solvent to extract the steviol glycoside from the leaves; and d) separating the Stevia rebaudiana leaves to obtain an untreated aqueous Stevia extract comprising at least one steviol glycoside selected from the group consisting of RebD, RebE, RebN, and RebO, wherein any one or more of RebD, RebE, RebN or RebO is present in the aqueous Stevia extract above its common relative concentration as defined in (a).
