Want to swing a bottle or tap a glass of beer?
I must admit that I'm biased in this question, I have a keg-and-tap system at home and I like it a lot!
But there is a certain charm in popping a bottle open and taking a sip! With home-brewed beer there is just the slight problem of the yeast at the bottom of the bottle, it is there for the carbonation of the beer. After the fermentation the beer is poured into the bottles and a little sugar is added to each bottle and then it is capped. The beer then ferments in the bottle, producing the desired amount of CO2 and a sediment of yeast at the bottom. When pouring a home-brewed beer you have to be careful not to include this sediment or the beer in your glass will be clouded with yeast particles.
With a keg you pour in the fermented beer into your cleaned and sanitized keg, seal it shut and attach the C02 and beer hoses and you are done! You will have to invest in one or several kegs and a CO2 bottle,some hoses and connectors and some nice taps as well.
So, with the washing of all the bottles, the priming with sugar for each of them and the yeast sediment in mind, just washing one keg and then pouring clear beer out of a tap is a very attractive solution for me. It is more expensive and bulky but I find that the convenience makes up for that in the long run!
