Identification of yeasts Isolated from processed and frozen cocoa (Theobroma cacao) pulp for wine production BABT
Trindade,Rita de Cássia; Resende,Maria Aparecida de; Barreto,Eriana Gomes Serpa; Mendes,Taniella de Carvalho; Rosa,Carlos Augusto.
The alternative use of cocoa (Theobroma cacao) for wine production was tested. The pulp samples, obtained from Formosa farm, Itacaré, Brazil, were diluted, homogenized and inoculated on Sabouraud dextrose agar medium (SDA) and incubated at 28º C for 5-8 days. Selected colonies were tested for the ability to ferment cocoa pulp and divided into fermentative, non-fermentative and weak/late fermentative species. Isolates characterized as fermentative were further tested in a small-scale wine production plant and identified. Species from the genus Brettanomyces constituted the main fermentative yeasts, with the exception of two Kloeckera apis samples. The final wine product was normally pale or clear, making clarification unnecessary, and with a sweet or dry...

Natural endowments, production technologies, and the quality of wines in Bordeaux. Is it possible to produce wine on paved roads? AgEcon
Gergaud, Olivier; Ginsburgh, Victor.
We study whether quality assessments made by wine experts and by consumers (based on prices obtained at auction between 1980 and 1992), can be explained by variables describing endowments (land characteristics, exposures of vineyards) and technologies (from grape varieties and picking, to bottled wines). However, since technological choices are likely to depend on endowments, the effects can only be identified using an instrumental variables approach. We show that technological choices affect quality much more than natural endowments, the effect of which is negligible.
