Bubbles = rich taste

I learned some new words in English:

aeration - the act of charging a liquid with a gas making it effervescent.

effervescent - to emit small bubbles of gas, as a carbonated or fermenting liquid.

By accident, I discovered that I get nice bubbles on the cup of coffee, if I pour the coffee into the cup from high enough. I did this first to get nice bubble images. But I also noticed it made the coffee taste better. I then did some searching, and found several articles that support my observation.

So, just like aerating wine, one can aerate somewhat any drink, and it probably improves the taste by bringing out the flavors.

It is of course recommended to do this over the sink, to avoid spilling coffee all over the place, and not to burn yourself with hot coffee.

On one article it was claimed it is just the cooling that makes the difference. But try it yourself. Pour first one cup of coffee from height and taste. Then pour another cup close to the cup, and let it cool down for a few minutes. Feedback on this is welcome ;-)

I then also remembered an old "belief", or more as a playful superstition from my childhood. If the bubbles on freshly poured coffee form a whirling float of bubbles in the middle of the cup, then one should wait and see on which side of the cup those "coins" end up. If they end up to the opposite side, one will loose money. But if they stop onto front side, one will become rich.
