Corona clarity

The Corona is the name given to the hot plasma atmosphere of the sun that can be seen clearly during an eclipse. It is also the name given to a brand of beer and also a group of viruses. 

The only connection Corona beer has to the Sun's atmosphere is that the beer company wants you to associate their brand with the Sun. The virus is round and has a fuzzy surface so I guess it reminded the people that observed it of the sun's Corona. The three things are not connected. Beer is made with water, yeast and mash plus Hop berries to make it taste bitter I believe. The yeast eats the mash and makes alcohol and carbon dioxide and ethenol. I think the yeast is then killed with heat afterwards leaving the beer mix and the ethenol is removed.
