Blackberry Top Up?

[Clann]

I have 5 gallons of blackberry wine in a 6 gallon secondary. It will need racking soon and all I have are 6 gallon carboys. What would be a good choice of store bought wine to top up with? I would like to do it with something kinda cheap as I am on a pretty tight budget right now. Mabye a box wine or something similar?
I know it would probabily be just as cheap to buy a 5 gallon carboy but the wife said and I quote,"You can't buy any more equipment till you build a room on the house to put all your **** in."
I guess I have too much stuff:cross:

One other option - get a couple of bags and fill them with marbles to displace 1 gallon of volume. Use glass marbles, and personally I'd double bag the filter bags (like the ones used for grain or juice).

No, thank you. I am looking to top up not add marbles.

Do you plan to back sweeten? You could add some more berries and water if your not worries about diluting abv. I cant comment on adding wines, I've not done it but I've always felt that it would change the flavour too much, especially with cheaper wines.

Yes I am going to sweeten after adding a f-pack that I will make withabout 4# of berries.

Any red wine will do. I have mixed Merlot with it and it comes out great....
