I have made loads of washes over the years, first I was doing 25L washes and then later 50L washes, but I never thought to compare the time it takes..
Only asking because I finally got around to making drink for the holidays and it is only a few weeks away :)
If no one knows definitively I will do both a 50 and a 25...... heck I might do that anyway...
But if anyone does know for sure, let me know.
