[Q]: [header] How to buy wine for a gift [title] Go mid-range to high end. [step] It's tempting to buy a cheap wine to give as a gift, particularly if you don't know much about wines. However, cheap wine will taste cheap. <sep> (A) Buy the cheapest wines possible at low prices for a lot of fun and a nice gift. [substeps] Vintage wine is well worth the cost, but it won't taste well if you're not buying the bottle. (B) A higher end wine will go right up top and faster, so full quantities have more potential to go up the price of a bottle. [substeps] Anyway, consider your palate when determining whether a bottle is a good choice for your party. (C) [substeps] Spend time visiting upscale restaurants near your destination and learn about wines on your visits. Ask for the wine they recommend to see if you can trade it for cheaper. (D) That's not to say that you can't get a decent wine for a reasonable price. You just don't want to pick the cheapest wine, especially if you've never tasted it yourself.
[A]: D
