I will address each question in turn, listing the answer options as they correspond to that question and then analyzing why each option is correct or incorrect. Question 1 analysis: - Options presented: Botrytis cinerea, Saccharomyces cerevisiae, Oenococcus oeni, Saccharomyces cerevisiae (as part of the second and fourth questions, but for Question 1 we focus on Botrytis cinerea as the listed option here). - Botrytis cinerea: This fungus is well known for causing Botrytis bunch rot, and under certain conditions (the so‑called noble rot), infected grapes develop shriveled berries with concentrated sugars and distinctive honeyed, apricot-like flavors, which is the classic association with sweet wines from regions like Bordeaux and Alsace. This makes it the correct identification for the described infection and resulting sweet wine. - Why the other options are not correct for Question 1: - Saccharomyces cerevisiae: This yeast is the primary organism responsible for alcoholic fermentation, not a mold causing grape ......Login to view full explanation
