Hey all. New to all grain. Jut did my first all grain with BIAB yesterday. As I've said before on here I only do 2.5g at a time. I've just been halving recipes online or making them with my LHBS but been wanting to try some kits from the different websites available (midwest, northern, etc...) and just planning on halving the batch and going batch, washing the yeast and doing the other half in a couple months with the washed yeast. Was just wondering if I get them milled from the website, don't have a mill, are the different grains all mixed together? If so, can I still half them? And for when I do get a mill how do they come unmilled?
