Third brew attempt with homemade malt

Over the course of the last week I have been malting the remainder of my 25 pounds of barley seed. I had about 4 pounds left after the other two attempts, which produced much less sugars than anticipated. The first batch was a total failure, but I attributed my low efficiency to poorly crushed grain (I tried to smash it with a rolling pin in a zip-lock freezer bag). For the second batch, I built my own inexpensive grain mill, which worked great, but I still had poor efficiency for some reason. So I researched the process a little bit more and decided that this time I would allow the barley to germinate longer than the other two times. Also, I would use an extra long protein rest (45 minutes), and an extra long sacharification rest (90 minutes), while continuing to utilize the benefits of a decoction style mash.

The malting process was pretty much the same as last time, just longer (about 5 1/2 days). The only problem I encountered was in the last 2 days mold was rampant. I had to constantly stir the grains and even remove a few clumps that had started to fuzz over. I let the grain develop until all the shoots were at least 100% the length of the seed, meaning many had busted out. The drying process was much faster since I had less grain to dry, and it had more time to succumb to evaporation prior to kilning. The end result was noticeably different - sweeter and plumper! I had a good feeling. I kilned the grains longer than usual until the smell of chocolate and coffee filled the house.

Today I had to do some work online from home, so I decided to brew at the same time. I chose to keep my batch size down to 1.5 gallons, hoping for a high gravity reading. It took most of the day since I was using such long temperature rests, and also just being as meticulous as possible. But in the end, sadly, my efficiency was only about 35%. Unbelievable! I've tried everything and I just can't seem to make this work. I think the only other factor is the temperature used to dry the grain - my oven won't go below 170 degrees, which is a little hot according to what I have read. I keep the door propped open for circulation, but maybe the heat killed the enzymes? In any case, this batch of grain was the most delicious smelling yet, so I am sure this beer will taste great despite being lower on sugars than expected. The odor was like pure bitter chocolate - so intense I could taste it! As with the other two failed batches, I added a little bit of honey and some sugar at the end to bring up the gravity. I am currently about half way through my keg of "Homemalted Pale Ale" (the first crazy batch), and I have to say it is pretty tasty, so I'm not too worried about the others.

One other thing I wanted to mention: the rollers of the homemade grain mill became noticeably smoother after only two batches. I actually had to rough them up again today so they would grind properly, leading me to believe that this cheap alternative may not be quite as perfect a solution as I thought. Oh well, I will end up buying a real one eventually.

In conclusion, I think that after malting 25 pounds of barley at home, and brewing it into 3 different batches of homebrew, each with very poor efficiency, I would say that I've had just about enough of "home-malting." Yeah, I'm done. I've invested countless hours into this project and I don't feel that the results were worth it. I am glad I tried it and maybe I will revisit it someday - possibly during the dry season when I might be able to put my grains out in the sun without worrying about rain - but for now I am going to move back to commercially produced grain. I already ordered the ingredients for my next batch - a Belgian Dubbel. So I'll be brewing again in the next week - see you then!!!

Second brew attempt with homemade malt

So now that I have my own nifty, homemade grain mill and my own awesome homemade malted barley, I feel pretty cool. The day after I finished the mill, I took my second batch of malt (about 10 pounds) and crushed it. The next day I didn't have to work until the afternoon, so I got up early and began my second attempt at brewing with the homemade malt. I felt very confident now that I had crushed my grains properly, and I can't even begin to describe how unbelievable they smelled after milling. So sweet, so delicious, almost like chocolate and coffee!

I performed a similar session as last time, using a double decoction. I also tried boiling a bit longer. In the end, however, my gravity came out at 1.026 - still very low, but a major improvement over my first attempt. Unfazed, I simply added some pasteurized honey and pitched my yeast - I can see now that this is going to be the biggest challenge I have faced since I started brewing.

So I went back to the internet and began searching for more information, trying to discover what else I could do differently. I ended up finding out a few more things about home malting. First, you always have to use at least 30% more grain to achieve the desired results. Apparently, homemade malt will never have the same potential as factory made. Second, it is recommended that you employ a very long protein rest, and also an extra long sacharification rest - most of the information I found said at least 45 minutes at 122 degrees, then at least 90 minutes at 150 (keep your sacharification temp as low as possible). And lastly, boil longer (like 90 minutes) to reduce dimethyl sulfide flavor (tastes like cooked vegetables or shellfish/ seafood), and aid in sedimentation. I guess homemade malt produces a lot more sediment and is harder to clear. I believe this is true because just the other day I transferred my first homemalted disaster to the secondary, and it looked very hazy. I added some polyclar to try and aid in clarification - I am definitely very curious about this weird concoction and how it will look and taste.

So now I have 4 more pounds of barley remaining. Next week I am planning on malting it, and this time I would like to try letting it sprout just a bit longer than I did with my first two batches. Maybe I can get some more sugars out of it and improve my efficiency that way as well? I was planning on smoking the last of my barley, but considering how much I have been struggling to make this process work, I think I will just stick to the basic plan again and shoot for better results.

Also, I just wanted to mention that the whole mashing process that I have been using to make my crystal malt is not necessary! Apparently you can accomplish the same thing just by putting it in the oven and adjusting the temperature properly for the desired time, then kicking it up to caramelization temps.

And so the adventure continues, challenging but ultimately very rewarding. I love it!
