I will be making a Munich Helles soon. I need to mash 1/2lb if Munich and 1/4lb of Melanoidin malts.
As time is always an issue, can I mash the grains early and then refrigerate? Placed in a sanitized container naturally.
Then when I'm ready to do the full wort boil on the weekend; just add the mashed wort to the Pilsen DME and required water?
If this can be done without any issues, how long would it last?
