It's the same time every week, and now you have an official excuse to belly up to the bar and practice those 12 oz. curls
According to BroBible:
• “Beer o’clock” – officially the best time to have a beer – is exactly 6:31 p.m. on a Friday. And, yes, taste really matters. More people are in it for the taste than you may think – 52 percent rank taste first in making their beer selection.
