> generally people prefer cold beer
Do they? But why? Why would they? Are they simply accustomed to tasting it that way? I should say "not tasting it" because chilling a beverage basically kills its flavours, and they never make it to your tongue correctly.
I would say that many people would be surprised and amazed if they tasted such things as Pepsi without ice, and without coming right out of the fridge.
Unfortunately, any lack of refrigeration really messes up supply chains and will eat into anyone's bottom line, so it's not a realistic goal.
This stuff is panel-tested out of the wazoo. There's a reason bitterness, hoppiness, alcohol levels, differ market by market, even on brands of the same brand/line extension.
Beer also does not require refrigeration throughout the entire supply chain, they happily sit in a warm warehouse waiting to be picked up by an unrefrigerated truck, only to be cooled at the outlet or consumer.
