So after talking about it for a long time I have finally managed to get my first full mash brew underway. After slowly collecting up brewing equipment and with a concerted push at Christmas and my birthday I finally had everything I needed to get started.
It all started out with a mash tun. I may post separately about how I built that (but basically I used
this page as a guide). A huge pot, an auto syphon, a cooling coil and a recipe from
Brewshop for American IPA, along with the ingredients to make it (not to mention a very rainy day where I couldn't do any painting) and there were no more excuses not to see what this full mash was all about.
Now, as with all brews, you can't do anything until you have cleaned and sanitised your equipment. Unfortunately more equipment means more cleaning and sanitising so the morning was half gone before I could even start with making my mash.
Everything I knew about brewing was from reading about it or using common sense. I had never actually watched anyone brew beer this way before so there was a bit of feeling my way along. The old kitchen jug in the garage served me well for hot water. Even though the water boils at 100 degrees it is already much cooler than that by the time it hits the grain so as long as I used boiling water each time it was easy to reach the required 76 degrees. Once I had poured what felt like a fair amount of water in I closed the lid to the mash tun and left it alone for an hour.
After an hour I came back, coiled the outside tube into the huge pot I had received for Christmas and
turned the tap. A clear brown liquid made its way down the tube and slowly began to fill up the pot. After a while it reduced to a trickle and it was pretty clear that there wasn't going to be enough liquid to make up a full brew. However I had read that this was not uncommon and to get the most out of your grain you should sprinkle water over it in an exercise known as sparging. I didn't really have anything to sprinkle the water across the top but gently pouring more hot water seemed to slowly eke some more liquid into the pot. After a couple of hours spent doing this I was getting pretty bored so decided I would have to make the best of what I had.
I carried the big pot through to our kitchen (unhelpfully at the other end of the house) and placed it on the stove top to boil. Before long the liquid was happily boiling away creating dirty looking brown foam that filled up the pot. I added the hops in the way described by the recipe and the brown foam started to take on a green tinge.
After an hour of boiling I took the pot off the boil and then back into the garage. I placed it down on the concrete floor and lowered the cooling cool I had received for my birthday into the hot pot. Unfortunately the pipe was designed to screw onto an outdoor hose tap and I was using a normal indoor laundry sink. However ,a firm hand holding the pipe on the end of the tap did a fair job at keeping the cold water running through. I might have to see what I can do with the end of that pipe for next time. After quite some time the liquid was down to the required temperature of 20 degrees.
It was time to transfer the liquid into the fermenter. I could tell that there was a lot of sediment/muck in the bottom of the pot so I decided to transfer the liquid using the easy siphon I had also received for my birthday. It also seemed a way to avoid spilling it all everywhere when pouring the big pot into the fermenter. Unfortunately I couldn't really see what was happening at the bottom of the pot so ended up siphoning a lot of the sediment through anyway. I guess it adds to the flavour...it was also clear that there wasn't really enough liquid there to make a full batch. I few more jugs of hot water helped bring it up to volume although I assume it will dilute the final result. Last step was to throw in the yeast and the test the specific gravity. Still no idea what testing that all meant but at least it gave me a starting point as I left things to brew over the next couple of weeks. No hurry so might as well give it plenty of time to do its thing.
I emptied my wet grain out into my compost bin so hopefully the garden will benefit from the brewing goodness too.
