An article about crushing and de-stemming. De-stemming before crushing is far better than crushing first.

  Crusher/De-stemmers:-

With these models you can adjust the gap between the rollers, a couple of nuts have to be undone and one roller slid outwards before re-tightening.
If you open up the gap then you have less crushing; however, there are gear-cogs on the shafts of the rollers, so increasing the gap will cause the cogs not to connect into each other as much, if the distance is too great then the cogs can become worn.
The optimum gap depends on the size of the berries and how easily they come off the stalks, this varies with grape variety and ripeness.
If the berries are hard to remove then you will need to tilt the crusher/de-stemmer (e.g. with a block of wood under the outlet end) so that it takes longer to push the bunches 'uphill'.
The stalks fall out at the end of the machine, there should be a bin to collect these.
Unripe berries are best dispensed with, but it is possible to put stalks back through the machine if you feel there are good berries still on.
