Bottles
Bottles are necessary when the wine has finished fermenting completely. The bottles preferably don't have a screw cap, but a cork or a flip-top instead. Be cautious with the cork, because if the fermentation has not completely finished yet, the pressure within the bottle might push the cork out again.
Where to be found
In most home stores. Personally I prefer to buy the 0.5L IKEA flip-top bottles, since they can be reused quite easily.
