This is a common step in the hobby of homebrewing, just like going from extract brewing to all grain. It is something every homebrewer will have to decide on at some point. Bottling and kegging are the two popular options in packaging homebrewed beer. Choosing between them largely comes down to time vs. money. Bottling is time-consuming but very inexpensive. Kegging costs more in equipment, but saves you time since you do not have to package and clean each beer individually. There is also the question of preference: Do you enjoy drinking beer from tap or bottle? Some might not see the time spent on bottling as a negative thing as it is also a part of the hobby.
When bottling beer, you need to prepare the beer to carbonate in the bottle at the right level. Bottling consists of four steps: cleaning, sanitizing, preparing the beer and filling the bottles. You´ll need relatively simple and inexpensive equipment: a large "spoon", a bottling bucket, a racket cane, a tube for moving beer from the bucket to the bottles, a bottle filler, sugar, bottles, a capper and bottle caps.
The obvious advantage to kegging is the ease of cleaning compared to bottling. There are, however, some drawbacks to kegging your beer. The equipment needed costs more than it does for bottling: A keg, CO2 tank with regulator, hoses, dispenser and fittings. Buying all of this brand new can cost over $200. It is also possible to buy a keg and CO2 tank used in good condition with new hoses, regulator and fittings for $110- $160. You also need a way to cool the keg. It obviously does not fit in a regular fridge. You would need a larger cooler, preferably a dedicated one for the kegs.
