This past weekend I brewed my first all grain batch. It was a small batch, just one gallon, but it was a lot of fun. I have done three extract brews but really wanted to try an all grain batch. I don’t have a lot of extra money to put into more home brew equipment right now and didn’t know what I wanted to do for a lauter tun. I also really didn’t understand what it was I was supposed to do with the lauter tun and how to do the sparge. It all seemed a bit overly complicated to me.
I decided to start out as simply as I could. I bought a 1 gallon home brew kit with ingredients from the Brooklyn Brew Shop. They specialize in small kits that can be made in small apartments in NYC. Because it’s only a one gallon kit, I had everything that I needed to brew it. I actually bought two kits, I bought the special Black and Tan kit that they have available. This past weekend, I brewed the dry stout.
With extract brewing, the malt extract is already made and ready to be used. Most kits come with some specialty grains that you steep in the brew pot to add some flavor to the wort but that isn’t where most of the fermentable sugars come from. Most of that comes from the malt extract. If you don’t already know, the wort is the liquid that is created from the water, malt and hops to which you eventually add yeast to turn it into beer. When you are brewing with all grains, there is no extract and you are creating all of the sugars that the yeast needs to eat, grow and create alcohol.
The first step is to bring your water up to temperature (160 degrees) and add the grains to your brew pot. This step is called mashing in. I have heard this term before and read about what it is but I learn much better by actually doing so a lot of things became clear to me this past weekend. The mash turns into an oatmeal consistency and stays in the brew pot for an hour. You have to stay on top of it and make sure it stays in the proper temperature range. I am assuming this is the step where the enzymes are doing their work but I don’t really know. After an hour, you raise the temperature to 170 degrees. This is called mashing out.
Here is a pic of my brew pot after this step

The next step is the sparge. During this step, you pour water through the grains in an attempt to extract all those wonderful flavors and sugars that you created with your mash. You do this by using a lauter tun. In this case, the lauter tun was simply a strainer put over another pot. I poured the contents of the brew pot into the strainer and was surprised at how little liquid there was. I hope I didn’t do anything wrong as there was only a trickle of wort that poured through the strainer at this point.
The next step was the actual sparge. In this step I poured 1 gallon of water through the lauter tun in an effort to extract more of the precious flavors and sugars that I worked so hard to create. You want to end up with 1.2 gallons of wort when you are done because you need to overcompensate to make up for what you will lose during the boil. Unfortunately, I don’t think I was at the 1.2 gallon mark. Not sure what I did wrong but I was barely over 1 gallon. After the sparge, I ran the wort through the grains one more time.
Here is what it looked like

After this step, it’s back to what I was used to doing and that’s the boil. You boil the wort for 60 minutes, adding hops along the way at specific times. The hops add both aroma and flavor to your beer. After the boil, the wort is cooled down as rapidly as possible and added to the fermentor. I was way off on quantity of wort, I only had 2/3 of a gallon, I had to add more water to the fermentor to get it up to the gallon mark. Once I did that, I pitched the yeast which just means I put the yeast in and shook the fermentor to get the yeast going.
So far, I haven’t seen a lot of activity. I hope I did everything correctly. I don’t know why I didn’t have more liquid after the sparge and I hope I did the right thing by adding more water to the fermentor. I am going to take a hydrometer reading this weekend to see where we are at.
