Final answer:
When a guest orders a bottle of white wine, you should take out a wine opener, wine bucket with ice, and appropriate wine glasses; accessories like a wine pourer or stopper may also be included to match an elegant setting.
Step-by-step explanation:
When a guest orders a bottle of white wine for their table at an event with a setting described as having a rack of wine jars decorated with grapes, it is customary to bring the bottle out with a few specific items to enhance the experience. Generally, this would include a wine opener, a wine bucket with ice to keep the white wine at the ideal serving temperature, and wine glasses appropriate for the type of white wine being served. Given the detailed description of an elegant event where the guests wear fine linen clothing and the décor includes elaborate motifs of vines and flowers, it would also be fitting to bring out a clean and elegant wine pourer or stopper to maintain the sophistication of the service.
