I think the size of the tube/bubbler and the amount of diffusion along with the temp of the water plays a big part in this. A smaller piece (not too small), like a 12 tube with just a little diffusion, filled with warm water will retain the taste a whole bunch better than a larger piece with a lot of diffusion, filled with cold water.
