What is the most optimal shape for a glass to keep my beverage cold ?

I just took a cold beverage out of the fridge and I wondered what shape of glass would be perfect to keep the beverage cold the longest. Would a spherical glass have less surface to take heat from? Or would for example a high but small diameter cylindrical glass be better? Or would they behave the same? What would be the ideal ratio between beverage-to-glass and beverage-to-air surface size? (while still considering the glass to be drinkable from)

A traditional wine glass actually gets pretty close. It's important to the taste and aroma of wines to be served near their ideal temperature, and the wine glass helps.

The bottom is nearly spherical, minimizing surface area. The narrow stem minimizes conduction from the base, and it gives you a way to hold the glass that minimizes conduction to the liquid. The high walls and narrow opening keep airflow away from the surface of the liquid to minimize convection.
