just get them to mill it for you.
It will still work no problemo.
I do 4kg's ( max ) of grain per 19 lit pot. Works great. Using Nicks Thread as a guide.
I have found those single grain batches are a bit boring...they work perfectly though
But if you love pils'
Give one a go . keep the sugar for your corn flakes. I did it once and noticed that **** home brew taste which I put down to adding sugar like in the kit beer.
I am sure people will say I am wrong ..but in my mind I know I am right
try this ( pick the cheapest grain to start with and JW pils is the cheapest one of all I think
3.8 kg JW pils
.200 kg weyerman carapils
25 grams saaz pellets at 60 , 25 and 5 min from end of boil. Put them in their own little bag during the boil.
Ferment pretty cold between 10 -15 ( great now mid winter ) give 3 weeks in fermenter. Using that pils yeast in the yellow packet.US-23???
I would even stick fermenter in spare fridge for a few days at the end to clear it up some more.
This is just a standard recipe that I would knock out off the top of my head and I bet it works pretty well.
good luck.
It is not as precise as it all sounds...I make it up on the spot all the time and they all seem to be pretty good.
Just look at the recipe base on this website and do a version close enough to what you have available.
