A magnum is a double bottle of wine or champagne. One reason it works well for a party is it's fairly impressive to look at. Plus, because it's double the size, it will last much longer than a single bottle of wine. Your host will appreciate your thoughtfulness.  When choosing a wine for a party, sparkling is usually a good option. If you insist on bringing a standard bottle of wine to a party, give it to the hosts before the party, and let them decide whether they want to serve it at the party or not. On the other hand, when you've been invited for dinner to a small gathering, such as a dinner for about four people, a regular bottle is appropriate. A regular bottle will provide enough wine for each person at the dinner, which is why it's appropriate. Ask the hosts ahead of time what they will be serving. Then you can get a wine that matches the dinner, such as a white wine for fish. If you're not sure what goes with what type of food, ask at the store. When it comes to weddings or other big special occasions, such as birthdays or Christmas dinner, plan to spend a bit more on the bottle. Weddings especially call for a more expensive bottle. If you don't want to spend that much, skip the wine. You'll be safer buying something off their registry. That is, you don't want to buy wine if the host doesn't drink wine. For instance, maybe the host enjoys alcohol, but they don't like wine. Another situation you may run into is the host may not drink at all, due to personal choice, health reasons, or religious reasons. If you're not sure, ask.
