Yes you can chill red wine at any stage. It is typically served at room temperature but chilling after the bottle is opened will slow the oxidation process. What i recommend is that you have a smaller bottle handy so that you can fill it up to the top and store it somewhere. That will leave you with a drinkable amount and will also make sure that the leftover wine does not oxidize.
Yes, and it's also a good idea to pump air out of the bottle or inject an inert gas into the bottle to lengthen preservation.
no
you can if you want to but i say that you should not because it kind of ruins the flavour in the beautiful ingredient.
No. Valpolicella, beaujolais and some light pinot noir can be served chilled.
It depends on which wine is in question.
White Zinfandel should be served chilled but, a red Zinfandel is not served chilled.
Not necessarily to chill a white wine glass, it depends your restaurant procedure. some say don't chill white wine glass because when you pour white wine into a chill glass it will mix with liquid water.
You should try the Harmon WCL100 Motion Wine Cooler & Decanter
Generally speaking, white wines are served chilled whereas red wines are not. However, chill or not any wine you wish if you prefer it that way. Wine isn't about rules but about enjoyment.
The taste of the wine starts to change as soon as you open it. Wine connoisseurs will advise that you drink the wine within a few hours of opening. I, however, often put the cork back in the bottle and finish the next day and it has never harmed me, and since I drink inexpensive wine, the flavor is pretty much the same.
no
Not all wine is red. There are also types of white wine and rose wine. But, red wine is red because of the reddish color of the grapes it is made out of.
Red Wine. :D
