How to store an opened bottle of Porto Wine?

Question

I have a nice bottle of Porto. I've never drank wine at home. How would I store the bottle after opening?

To b more precise, what do I do with what's left? I never drink more than a small glass.

Answer 1

A product that helps preserve opened wine is a can of nitrogen. You spray it into the bottle and re-cork. The nitrogen displaces the air (which has oxygen). Keep it cool. It should be drinkable up to one year after opening using this technique.

Answer 2

Port is much less fragile than non-fortified wines. First, close it with a cork. Air damages any wine, even fortified port. Second, move it to the smallest glass container possible, for the same reason - you want the least air in the bottle possible. Finally, keep it cool. Ideally, 50 - 60 degrees, but anything above freezing is fine, so long as you warm it back to 60 degrees or so before drinking.

Answer 3

get an air vacuum wine pump at any wine store, their inexpensive and you get a few caps with it so you can store a few different bottles at once. it sucks all the air out, and you can use it over and over with the same bottle. this should solve your dilema!
