I think google ate my posting...

So a 25 cm in diameter by 33 cm high (usuable height of 13 in)
press is adequate for a couple of 23l carboys of wine. When
someone says one press will fill a 23l carboy are they filling
the press with grapes and completely pressing out or are they
pressing one load, opening the press up again and adding more
grapes and pressing again? In other words, the first would be
one full load completely pressed, the second would be a couple
of loads squeezed down and more added before fully pressing.
