Our fruit wines are hit and miss, but this bladder
bucket isn't.

We tried bottling for a couple years, but it was so time-consuming and difficult to store. We then went to 3-liter plastic bladders, and finally graduated to 20-liter bladders. We can fit most of our 7-gallon "Fermonster" into a 20 liter bladder, leaving a couple of gallons for bottles/friends/immediate consumption.
For the last three years, we've been keeping those 20-liter wine bladders in regular (tape-reinforced)
cardboard boxes. We keep those boxes in the cool garage, just waltz in with a cup when we need a hit of hootch. Those boxes have worked well -- repeat use each year, no problems -- but each time we bag, we spill a little on the box, and the box steadily weakens and goes out of square. And the boxes have no handles, so they're a bit hard to maneuver, especially when full.
This year, to avoid making new hard-to-handle boxes, we're trying a 5-gallon plastic bucket to hold the 20-liter bag. We drilled a 1/2" hole near the bottom, widened it to 1-1/8" with an Exacto knife, then press fit the black faucet through the hole, into the bladder receptacle.
We filled the bladder via siphon into the screw-top, and the bladder held nicely. The full bladder fits the 5-gallon bucket just about perfectly. And the bucket has a handle, making it much, much easier to move around.
