Final answer:
The term "Sec" on a wine bottle signifies that the wine is dry, meaning it contains no perceptible levels of sugars and is not sweet.
Step-by-step explanation:
On a wine bottle, "Sec" indicates that the wine is dry. This term is often seen on bottles of Champagne or other sparkling wines but can also be used for still wines. In the context of wine, dry is the opposite of sweet and refers to a wine that contains no perceptible levels of sugars. Wines are categorized based on the amount of residual sugar they contain after fermentation, with dry wine being at the lower end of the sugar spectrum.
