VacuVin makes a hand pump vacuum container specifically for coffee. Using a wine bottle is a creative way to save money (about $30) but I would think that funnelling the beans into the bottle would be tedious. Bottles also suffer from the same fixed volume problem that the VacuVin container does. That is, since you cannot fully evacuate the container or bottle (I found I could only remove 75-80% of the air with a VacuVin pump), the air still remaining increases as you use your coffee beans.
An alternative product called the Airscape takes the opposite tack, reducing the volume but not pulling a vacuum.
Which removes more air? If you have enough coffee to nearly fill the VacuVin (or your wine bottle) pulling a vacuum is better. As the amount of coffee drops you reach a point where reducing the container volume will result in less air than vacuuming with a hand pump will.
You could do even better by both minimizing the volume and then pulling a vaccum. That can be accomplished with Ziplock vacuum bags. They use a hand pump and are not particularly fancy.
Since you cannot fully eliminate the oxygen with any of these inexpensive methods you might wonder if they offer a significant improvement over just keeping your beans in a jar. Opinions vary.
Another approach is to reduce the temperature by taking one or more small portions of beans, squeezing out the air and sealing them tightly in ziplock bags (or those vacuum bags), and then putting them in the freezer until needed.

Air and light are the enemy to beans. For short term storage < 2 weeks, I use an opaque canister with a rubber seal and a flip clamp. It's simple, cheap, and fast to open and close. It looks something like this one: Click Here (www.crateandbarrel.com)
For anything longer I vacuum seal bags with a 2 week supply and freeze them. If you don't want to vacuum seal you can just use a ziplock bag and a straw to suck out the air.
