Firstly make sure you have all the basic equipment required for all the phases as it would ruin your batch if you got halfway and suddenly realised you are missing a piece - here is a list of the basic stuff you will need for this mini all-grain batch.
Handy Tip: the eco-friendly way to get your sanitation bucket filled up is to stick it in your shower and catch that first bit of water that you usually run as you wait for it to warm up anyway - this way it does not run down the drain and go to waste. I use Iodophor as my sanitizer and it comes with a recommendation of 10ltrs water to 15ml Iodophor - you will be surprised to see how quickly you "waste" 10ltrs of water...
To get started you will need to measure out and then heat up some water in the big pot to around 73-75 degrees to prepare it for the addition of the milled grains.
From here you are not out of the woods yet as I recommend you use that second pot to start heating up some sparge water. If the temperature of your mash starts to dwindle you can simply use some of this heated sparge water to bring it up a little, but be sure to leave enough to run through the grains later.
Make sure that you pour it all over the bag to ensure that you extract as much from the grains as possible. Once you have drained the bag with all the hot water you can set it aside - I usually just take the strainer with grain bag and just place it in the now empty sparge pot as it will still capture a couple of milliliters that you can add to the boil later - every bit counts!
Just in case you are like me and you need some visuals, I have posted some pics in the gallery section showing exactly what has been discussed here in phase one.
