So I'm going to be constructing a simple mash/lauter tun out of a 3 gallon rubbermaid cooler like RichBrewer outlined in a thread for partial mashes. I've read a lot about all-grain a few books and here (didn't realize that all-grain would actually be as simple of a process as it sounds). Anyway, I'm not going to build an all-grain set up simply because I don't have the room. One question I just want to run by someone and get an 'OK'.
After my mash is complete: (batch sparging)
1) Begin draining wort and recirculate until clear; draining all liquid from mash tun into boil pot
2) Close valve, add sparge water, stir water and grains, let sit ~10 mins, repeat step 1
And if I want I can spilt the sparge water into two equal parts and perform two batch sparges.
Also since I'm only going to be doing partial mashes and boiling smaller volumes (~3.5 gals) should I refrain from splitting the batch sparges into two equal sparges because I might not have enough water for each sparge or should I be ok?
