Is there any point to head on a beer other than that some people thinks it looks better?
The right amount of head just tells you it's the right amount of fizzy. If there's no head often your beer will taste flat, but obviously it varies. I think it's just association, we think 'if it looks right it'll taste good'. I bet if you took the head off someone's beer then gave it to them they might say it tasted different. I certainly wouldn't trust a guinness with no head. Putting a head on a beer just for the way it looks is a bit like waxing oranges.
