Beer Question?

[Dark Angel]

Now why is it that the head of a poured beer is white froth and the rest of it is brown?

You're not allowed to answer Outlaw.....it's a serious question?



Just wondering....I need to learn something new

Has to do with ingredients. Sam could prolly explain better than me. Good tasting beer that is not flat usually has a foam on top, bad beer doesn't.

It reflects more light. I love beer.

Didja know that if you pour a Guiness just right, you can draw a smilie face in the foam, drink it, and the face will still be smiling up at you from the bottom of the glass? It's true, try it.

The refraction of light coming from bubbles (aka shperical transparent and very thin) reflects the predominant light source that hits it. Most of the odd color bands are absorbed. The sun and household lighting will always reflect white.

That's what I said.

Is that why they pay you the big money?
