this is a "shaker machine" it shakes EVERYTHING off of the vine. including snakes, birds, lizards, insects ..... most of it gets sorted out, A LOT of it doesn't. i stood and watched as the grapes went up the conveyor which leads to the press which dumps into the tanks. dude was picking out what he could but the grapes were 12 inches deep and moving by pretty fast. it wasn't like it was quality control or anything. he was more worried about large sticks that could puncture the bladder of the press. he had a 5 gallon bucket next to him that had a lot of mice and birds in it. it was the 2 4 foot long gopher snakes that took me by surprise though.
