Teff Beer Attempt - Step 5

So for those of you joining in late, we'll wait for you to catch up with the class. I promise the notes are at least entertaining.
 In Step 1, we decided on an idea for a beer and in Step 2, we looked for a recipe. In Step 3, we went shopping for equipment and ingredients. Step 4 was when we decided to malt our own grain. 
In this exciting episode, we will do the Mash and Boil which sound like a dance craze but results in standing around and measuring things. It is best to have a beer while doing this. It is like eating eggs and chicken, a bit perverse but pleasurable.

Had to decide on a date to do this and the beer festival season is upon us. The Only was having a beer fest and it started at 5 pm, so I invited a friend over for 2 pm to help me. I mean the next two pieces seemed easy, make a porridge, takeaway the scuzzy stuff, do another boil with hops and then add yeast to the cooled down liquid.

The day before, I did a check of ingredients and equipment. Had the kit but I was missing a strainer. Given the grain used, teff, I knew that whatever I used would have to catch 'em all (Pokemon reference). The dollar store provided. Might as well check on the other ingredients. Looked at the date and preparation instructions on the yeast. Need to take out for a few hours before, blah, blah, blah and expires June 2014. Wait, that was LAST year. Before we panic, a little breath to talk about what I have done so far in terms of a recipe to make 1 gallon beer.

~ 1 lb of malted teff
White Labs Belgian Ale Yeast
5 g US Fuggle Hops (split into half)
6 g Williamette Hops (split into half)
.25 lb of Belgian Candi sugar

That wasn't my intended recipe but that it what it turned out to be. The yeast... yeast is a living being and I am so glad for my cooking experience because I have used bad yeast before and most of the time it works out. There are some tricks and one is written on the bottle on how to create an activator. If you have made pizza or homemade bread you are probably aware of how to do this. Put the yeast in some water and add a little sugar to kick start it.

Like baby delivery in movies, the first thing I did was boil a lot of water. A whole stockpot of water. About 4 times what I thought I would need. I boiled it to make sure the chlorine was all gone.

I used a little of this water with about a teaspoon of sugar and set it on the counter. The vial was for 5 gallons and I was making 1 gallon. Should remember to put in 1/5th of the yeast later on.

At around 1pm, before my buddy was set to arrive I started down the merry path to get everything going. Added the grains to about 1 gallon of water and got it to between 140 and 155 degrees for most of the mashing process. The goal is to keep it in this range to get the sugars out. Normally, you try for a slightly higher range but teff malts at a slightly lower temp with the pocket being around 142. I have read all sorts of stuff on how different temps will affect the brew but the goal is to get all the sugar out. I slipped a few times below the 140 but never for long. It was hard to keep at a great temp, and I tried to err on the lower side so that I wouldn't stop the reactions necessary to convert starch to sugars.
Lesson 1: There may be a better way to keep a constant temperature. The oven. I think that is something to investigate for next time. 

When this liquid was tasted about 40 minutes into the process, it was sweet but a grassy sweet and not horribly sugar sweet. Not sure if that makes sense but there is something called the iodine test where adding some iodine to a sample of the liquid and stays brown then there is no more starch. This process is supposed to take around an hour and a half. I boiled for around 1.75 hours and still not fully converted. That is when I decided to add candi sugar to the boil. This conversion factor is really important for commercial brewers but for one gallon as unconverted starch is money. It is important to get the flavour for home brewers but sugar provides the food for yeast farts of alcohol and carbon dioxide.

At this time, you need to get the gunk out. I poured the liquid from the stock pot to a canning pot using the sieve to hold back the grains. Then you get help from your friend to put some warm water to rinse the remaining sugar from the grains. So, I get my friend... oh wait, he didn't arrive yet.
Lesson 2: Get better friends or only make 1 gallon batches. If this was a 5 gallon recipe, this part called sparging would have been horrible. And I would have to get a bigger sink. 
Make sure you boil a lot of extra water. I found that soooo much evaporated. So, I'll use the oven or lids or something next time. It doesn't matter that much as you can always add water into the overly sweet wort (that's what the official beer porridge name is) at the end of the process.

This process of sparging, well there has to be a better way but I'm not sure I know what it is. Some research will be necessary.

So, now you have this sweet liquid. I added some more hot water, the candi sugar and brought it to a boil. Looking at a bunch of recipes, I settled on 11 g of hops for an 1 gallon batch. Looking at a lot of recipes that used these hops, I decided on putting half the hops at the beginning and the remaining about twenty minutes before the end of the boil. All boils seem to be for an hour. So, I put in the first bit and stirred and waited and my friend shows up. We have a few beer while waiting. I put in the second set of hops and create an ice bath in my sink because the next part is to cool the wort so I can put yeast in and not kill it.

We finish our beer and my friend helps by almost pouring the wort into the ice bath.
Lesson 3: Don't get sloppy drunk and try this. There are two mistakes that I made after this point and one meh moment. Yes, this stuff is simple but not foolproof.
We cooled the wort down to room temp and move it into the container that I am going to use as my primary. We take a sample and I try to use the hydrometer. The only thing I actually can comprehend and figure out is that it bobs at the 6% level for beer. I have to figure out how to calculate the specific gravity better.

The temp is  as recommended on the yeast and I add the yeast that is sitting on the cupboard. All of it. Go back up and read the piece where I talk about how much yeast I was supposed to use. The good news is that I know that yeast will only eat the food that is there and then stop. Also, since it is old, I am expecting that it will underperform anyways. We will have to see.

I put the liquid into a carboy instead of the plastic pail because I wanted to watch it ferment. I have a few old fashioned jugs for the next step which I follow up with later. For now, I have this...

Stay tuned for the next few weeks where this becomes beer and I taste it.
