The best way is what I did.
I took 2 of the same porters. Let one sit on the counter til it got around 48-50 degree. Then got one straight out of the fridge. The warmer one had way more fruity, blended taste. The colder was more earthy and harsh on the back end. Then take a natty light, cold it is crisp and clean, warm it is just plain funky.
