Cloudy/opaque color with home malted grains

[geobotsar]

Hi guys
I have been experimenting with malting my own barley for a couple of months and made 3 batches with it so far.
The first 2 beers(a summer ale and a brown ale) turn out to have a very cloudy/opaque yellowish color and both had a grainy/wort like taste.
I was wondering if the cloudiness in the beer was due to proteins and if i used a protein rest in mashing if the issue was going to resolve.
Also can proteins impart a specific taste to the finished beer, if there is a high level of them in the malted barley and again is a protein rest going to help?
Thanks

probably a cheap and nasty grain , full of protein and nitrogen, and better suited to animal feed

hough, briggs and stevens wrote a book called malting and brewing science, its quite informative and easy to read

malting your pwn is not something ive done but im reading this at the mo, and it shows malting is a big science laden conundrum!

a protein rest at 50.c would undoubtably help
