I am just starting off a new 5kg batch of barley. I did in the past have a batch -25kg, that was full of cr*p including dirt,rubbish, peas, wheat and naked barley.
I did a few brews with it but it was a bugger to clean and sort.
I got the majority of naked barley out of it and the wheat but got fed up of picking individual grains out so fobbed it off in the end. But as stated elsewhere i did end up with a hazy clouded beer as it didnt clear at all, plus i forgot to stick in the irish moss at 15mins from end of boil too.
But tbh the beer is fine and tastes ok too.
I am supposed to be getting 70kg this time but it aint turned up yet (turkish promises!) so got a 5kg batch to be going on with. Its just begining to sprout too after 2 days soaking - i do it outside on my roof. Air dry on a big screen and soak in a massive bowl, i also leave mine half a day in water and half a day in the sun on the screen. Works for me rather than 2 hour soak and 8 hour dry and its generally ready to dry after 3-4 days.
