Quite a long winded title. Basically it comes down to this: What's the best way to pour a drink into a container with ice cubes in order to have the coolest drink for the longest period of time? I see a couple of ways:
1. Pour the drink in at a normal rate. If it only takes a couple of seconds to pour the drink it would be relatively safe to assume the average temperature of the drink as you finished pouring would be very close to the temperature it started at. This would mean there would be a fairly large difference between the temperature of the ice cubes and the temperature of the drink. Even if the drink were refrigerated the difference would be in the region of 10 degrees Celsius. If you use a drink at room temperature this difference would be in the region of 20+ degrees Celsius. This large difference in temperature would mean most of the cooling power of the ice cubes would be taken up quickly.
2. Pour the drink in at a reduced rate compared to the above (spend a minute pouring it instead of a couple of seconds). With this method the drink would be cooled as it was poured in at the reduced rate and this cooled drink itself would help to cool the additional drink that was poured in. This cooling effect (coming from the drink as well as the ice cubes) should mean that there is less of a burden being asked on the ice cubes, so they should last for longer and keep the drink cooler longer.
Thoughts? More suggestions for a better cooling strategy?
