<human>:  How can I tell if the wine I'm drinking is good or bad?
<bot>: The best way to tell if a wine is good or bad is to sample it and take note of your reaction. Pay attention to the smell, taste, texture, and finish of the wine and make a judgment based on personal preference. In addition, doing a bit of research on the particular type of wine you are drinking can help to inform you as to whether or not it is of good quality.
