Schizosaccharomyces, the only wine yeast that reproduced by fission whereas most wine yeast reproduce by budding. [4] Zygosaccharomyces, very alcohol-tolerant and can grow in wines up to 18% v/v. Additionally this yeast can survive in extremely high sugar levels (as much as 60% w/w or 60 Brix) and is very resistant to sulfur dioxide. [4]
The natural occurrence of fermentation means it was probably first observed long ago by humans. [3] The earliest uses of the word "fermentation" in relation to winemaking was in reference to the apparent "boiling" within the must that came from the anaerobic reaction of the yeast to the sugars in the grape juice and the release of carbon dioxide.
Saccharomyces cerevisiae (/ ˌ s ɛr ə ˈ v ɪ s i. iː /) (brewer's yeast or baker's yeast) is a species of yeast (single-celled fungal microorganisms). The species has been instrumental in winemaking, baking, and brewing since ancient times. It is believed to have been originally isolated from the skin of grapes.
Recently, several vintners have utilized native yeast fermentations. Skin-fermented orange wines and effervescent pétillant naturel wines (i.e., pét-nats) have popped up from producers across ...
The main bacterial groups are yeast, candida and Hanseniaspora. [5] In addition, microbial diseases of wine are mainly caused by yeast, lactobacillus and acetic acid bacteria. [6] This is because yeast may re-ferment a wine with high sugar content, making it cloudy and impure. [1]
Umeshu (梅酒), sometimes known as "plum wine", is a beverage popular in both Japan and Korea, made by steeping ume, or Japanese plums, in shōchū or another clear liquor such as sake. [10] It is not a true fruit wine, as the plums are not fermented.
Cut the strawberries in half and place in the bowl of a food processor. Blend until smooth. Add the syrup, plum wine, and lemon juice and continue processing. Pour the mixture into a 13x9x2-inch nonaluminum or glass baking pan. Freeze for about 1 1/2 hours. Using a fork, stir the icy portions into the middle of the pan.
