im going to have myself a go at this - going to acquire some of those upside down water container things for some decent volume
If you can find one go to an off-licence that does bring your own bottle. They get the wine in five gallon containers that are ideal for brewing. Fit the airlock to the tap with a piece of rubber tube and it will work great for volumes up to twenty litres.
Last time I did this I bought the last three bottles worth of wine in the thing and they gave me the container too. Often they will let you have one gratis though.
