Day 162 Brew Day! McQuinn’s Robust Porter

Becoming a porter.

Becoming a porter.

I got this recipe from my LHBS (Local Home Brew Shop) as a recipe of the month at 1/2 price! It came as a pumpkin porter, but since I already have a Scottish pumpkin ale in the works, I decided to “de-pumpkin-ni-fie” the recipe, add a little maltodextrin and just make a Robust Porter. The name McQuinn comes from my paternal grandmother’s maiden name…and it sounds good for a porter!

I’m trying to input my recipes and brewing sessions into Brewer’s Friend online, but they include some technical stuff that I’m not into yet. They also do not account for things like sugars or fermentables that aren’t part of the “mash” or grain steep. (I’m doing BIAB–brew in a bag–all grain brewing).

All set to brew, BIAB style.

So, when going from end of mash specific gravity reading, to pre-boil, to end of boil, the calculations show my conversion of grain to sugar and mash efficiency to be over 100% I’m also getting confused on water volume, grain absorbtion, boil off rate, etc. I start with 6 gallons in the kettle to mash, I know the grain absorbs some and the calculations have a standard default. Then I do what I’m calling a modified “sparge” where I drain heated water over the grains to hopefully wash out some more sugars from the grains…so, I’m adding about 2 gallons back.

Starting at 6 gallons and adding 2 gallons, minus what the grains absorbed, should leave me with about 7 gallons, but I swear I had 8 for the start of my boil. Had to keep the boil slow for most of the hour, because of the volume. Then I wound up with a slam full fermentation bucket.

I had to actually pull out a gallon to process separately, after I pitched the yeast. I used an oxygen tank with an aeration stone to aerate the wort for two minutes. I’m using Mangrove Jack’s British Ale Yeast. I was supposed to have 5.5 gallons after the boil.

The other thing that throws me off on all-grain brewing is the amount of trub. If you want a nice clear beer, you rack maybe 5.25 gallons off of 6 gallons and the rack again to 4-1/2 for bottling. I don’t care too much about getting a higher alcohol by volume (ABV) so much as I was a good beer and I want my 5 gallons! Ah well. C’est la biere!

So, I keep trying to tweak the brewing program and make notes that explain discrepancies, but it can be confusing. The main thing is that the actual brewing went well…except the temperature dropped in the mash at one point and I fired the burner to boost it and I over-shot from the 153 target, up to 157F. I stirred constantly for over 15 minutes to get it back down. Temperature control in the mash is the bane of my beer making! I’m not sure how it would do in an accurately judged competition, but my stuff still seems to come out pretty well, so I guess it’s okay. At the end of the brew, the color looks good and the OG reading is spot-on at 1.063 with an anticipated ABV of 6.32%.

Despite the brewing program confusion and water volume weirdness, this should be a pretty decent porter…and I have an extra gallon or so to experiment with. I’m using blow off tubes, since this is a dark beer and the volume is high.

Hit my numbers and still had more that I could fit in the fermentation bucket.

I may wind up combining them at secondary and then dividing them again at bottling time and add cold brewed coffee to one half or one quarter.

If anyone would like the details of the recipe, I am happy to share…let’s see how it turns out, though!

Update: 10/6/14   The porter has been chugging away all day!

Update: 10/8/14   It has only been a couple of days since brewing and the porter has already gone through a quick chugging fermentation period and by yesterday afternoon, had already slowed substantially. I think I might go ahead and switch from blow off tubes to regular airlocks. I don’t know if this is normal for Mangrove Jack’s British Ale Yeast…I have to assume so.

Day 3 after brewing, small jug...action substantially slowed.

Day 113 Brew Day!!! Something a Little Different. Rye PA?

The set-up.

The set-up.

It’s been a long brew day. I slept late and got a late start. After getting an idea about what I was going to brew, running to the local brew shop, topping of the propane tank and getting ice, I still had to organize, set-up and sanitize! I think I finally turned the burner on at about 2 p.m. I just finished…well, still have some more clean up to do…and it’s 7:45 p.m.

I was hoping to make a scotch ale; however, the recipes and comments I was hearing were all pretty much saying that I needed to be able to maintain a fermentation temperature of 68F for the first week and sometimes down in the 50’s for another 10 days. Since I don’t have anyway of temperature regulation, I decided I needed to go another way. In looking at styles that do better in warmer temperatures, I found a recipe for a wheat beer, with an option for rye, that sounded interesting. So, I started tweaking it and headed for the HBS to get further  input.  The original recipe I found is here:

I always like to give credit to originator! So, here’s what I did. First, I went with regular wheat, not red. Maybe some other time. I also decided to pick up some Citra hops, because I really liked what they did for a similar brew. I also remembered that I had a little Vanguard hops left in the freezer at home. And rather than go with a Weihenstephaner yeast, I decided to go US-05. This should help with my higher fermentation temperatures. For the honey in the recipe, I opted for orange blossom and instead of Lemon Zinger Tea, I’m going for Lemon zest soaked in vodka for the secondary…maybe some orange zest, too. Maybe I’ll call it “Rye Sense of Humor American RyePA”.

Gots all my pertinents and such.

On to the brew: I pretty much followed the recipe. There are two hops varieties in addition to the hops I decided to add. Bittering hops at 60 minutes, Cascade. Aroma hops at 30 minutes and 5 minutes, Hallertau and again at 5 minutes.  I added the Vanguard at the 30 minute marks, as well and the citrus at flameout.

My BIAB process went pretty smoothly, except it is hard to nail down that target temperature and regulate it there. I heated the strike water to 168 (a tad higher than I anticipated). I let it come down a little  before adding the grains. The grains only got it down to around 158F. I left the lid off and stirred a lot to try to bring it down to 152F. I went through that a couple time before it was ready to mash out.

The mash out, on the other hand, went smoothly. I hit the temp and I was able to maintain it pretty steadily for 15 minutes. Then it was on to the boil. I started with 7 gallons and went through most of the process as planned.

Dunking and draining...no sparging.

I did, however, have in my mind that the last two BIAB brews I did have a bunch of trub and tit really cut into the amount of beer I made. So, at the end, I added a gallon of  cold water which, of course, dropped my specific gravity reading.

I decided to pull a gallon of wort and re-boil it with another 1/2 pound of honey and a 1-3/8 oz chunk of piloncillo (Mexican raw sugar). I chilled that down and added it back. The refractometer was reading 1.047…I did a hydrometer check and it was reading 1.050 at 73F…that would be 1.051 corrected for temperature. Anyway,  I took one last refractometer reading and, low and behold, it matched the hydrometer at 1.051! I stuck the rest of the sample in the fridge to check the color later.

I had already rehydrated the yeast, so I went ahead and pitched it. Then I rocked the fermention bucket for 5 minutes to aerate. I’m going to go ahead and put a blow-off tube on this bucket, because it is pretty full. It would not take much krausen to foul an airlock!

Blow-off, in place and ready.

Now it’s time to finish up a little cleaning before I yawn myself to sleep!

Update: Sample tube…clear separation. Lots of trub! I really like the flavor of this wort…this has great potential!
