Brew Day! Yooper’s Oatmeal Stout

"The Con"

“The Con”

I prepared yesterday by purchasing my ingredients, getting my propane tank refilled, and buying 7 bags of ice.  The first thing I did was activate the “smack pack” of yeast that I used in this batch. It’s recommended to do so, 3 hours in advance of pitching. I’m brewing Yooper’s Oatmeal Stout, a recipe highly rated by several brewers and created by a brewer and moderator at the Home Brew Talk website. The recipe can be found at:   http://www.homebrewtalk.com/f68/yoopers-oatmeal-stout-210376/

The yeast is Wyeast British Ale II (#1335) and my batch is dated Dec 10th, so it’s very fresh!

It is supposed to supply 100 billion cells. The next step was setting up “The Con”. Basically, a table, a chair, the propane, burner, strike water and all the supplies/equipment…and a cup of coffee.

My local home brew supply shop was able to pretty closely duplicate the ingredients for me. I used 10 oz of Thomas Faucette Pale Chocolate Malt in place of the “Crisp”, Bairds 70-80L for the Caramel/Crystal Malt 80L, and Breiss for the 350 SRM Chocolate Malt. I also upped my Maris Otter to 8 lbs to satisfy my recipe builder program’s efficiency number estimate. (Brewer’s Friend) One other thing: I split my hops into 1 oz at 60 minutes and 1 oz at 30 minutes. Brewer’s friend estimated the IBU’s would be too high if I did 2 oz at 60 minutes.

For the process, I used the Brew in a Bag (BIAB) method that I have be doing since early last Spring. I heated my water to 159F and added my grains. I stirred to break up all the dry balls. My poor long plastic spoon needs to be replaced by a mash paddle! (Santa?) I turned off the burner and wrapped the pot with a blanket and a “space blanket” to try to maintain the temperature.

After 15 minutes, I checked the temperature and it had dropped to 154F. I gave the mash a burner boost, but overshot it up to 162F…rats!

I stirred constantly for a few minutes, but the temp wasn’t dropping very fast, so I added approx. 24oz of cold Culligan bottled water. I had the mash temp back down to just above the target 156F with 25 minutes to go in the mash. I wrapped it all back up again and it finished right on target. I hope the variation didn’t hurt too much.

I “tea bag” dunked & drained the grains a couple of times.

I also do a “modified sparge” that I have pictured in my journal before…I missed taking a photo this time. Basically, it’s a bottling bucket and tubing set up on a tall recycle container and I drain the water, in this case 1 gallon water at 167F, over the grains. The idea is to rinse additional sugars from the grains. Then I made sure the grains were well drained and squeezed out as best as I could, without burning myself. (I later added the grains to my compost container…I still have some in the freezer for making doggie treats.)

I checked the pre-boil specific gravity with my refractometer and it was 1.041…on target. I transferred the wort to the bottling bucket to measure the volume. It was right to the rim, which is 7 gallons.

I poured the wort back into the brew pot and re-lit the burner.

The boil was good…added 1oz of Willamette hops pellets at 60 minutes got a vigorous boil going.

I missed my 30 minute hop (also 1oz Willamette )addition by 5 minutes, but it shouldn’t be a big deal. Post boil SG was 1.066 amd the volume looked a little low, so I added 1/2 gallon cold Culligan bottled water and immersed the brew pot into an ice water bath.

I used 6 bags of ice and managed to get the temperature down to 72F in less than 25 minutes. A copper coiled wort chiller would be nice, though. (Uh…Santa?!) I checked the OG with both a hydrometer and refractometer. The hydrometer sample was 69F and the reading was 1.055. The refractometer was 1.056. After correcting the hydrometer reading for the sample temperature, the readings agreed at 1.056. I transferred the wort to a bottling bucket for primary fermentation and aerated it with oxygen for two minutes…

…and then pitched the yeast and sealed the lid.  The volume in the bucket appears to be about 6-1/2 gallons and is close enough to the top that I decided to go ahead and set up a blow-off tube, just in case. Now we wait for the yeast to start partying! According to the estimates, I’m almost dead-on the numbers. I should finish within about .05 of the ABV percentage projection.

When primary fermentation is done, I plan to split the wort and use 2 gallons to make a gingerbread version. Need to research those additions. I do plan to include some freshly grated ginger root. It really made a difference in my Scottish Samhain Pumpkin Ale, evidently. I had some guys at the local home brew shop taste it and the one I think has the most experience picked up on it right away. I assume the other componants will be ground ginger, ground cinnamon, vanilla (bean or extract?) … maybe some molasses? Not too much, though. It is fermentable and I found that a small amount really made a nice difference in a cider that I did earlier this year. Okay…updates as needed to follow!

Update: As of the next morning, there was no noticable activity. I sanitized around the lid and opened just enough that I heard some fizziness. I resealed the lid. By a few hours later, I could hear a regular chugging in the overflow liquid. So…things are good!

Day 154 Brew Day! Scottish Samhain Pumpkin Ale

Samhain label...no artist to credit, but it's beautiful!    Not for sale, so I guess it's okay.

After I picked up a new oxygen canister and some bags of ice, I set up for brewing my Scottish Pumpkin Ale that I’m calling “Samhain”, which is the Celtic version of Halloween and is pronounced “so-win”.

The recipe is a modification of a Scottish Ale recipe from a member at www.Homebrewtalk.com. I put the recipe together like this (but note the changes as I brewed!):

Non-grain fermentables added at 60 minutes.

Irish Moss added at 15 minutes.

 

***So, there were a couple of issues that required some changes. The efficiency that was the default in the recipe builder for Brew in a Bag (BIAB) brewing was 34%  and I evidently get double that.

Sparging...kind of.

After the mash, I had an SG of 1.075, which was already better than projected and I had not yet added the 3 lbs of DME I thought I would need to add to the boil…so I omitted it entirely.

The process went smoothly. If anyone is interested, there are other posts that go through the process. The color is really nice!

Sorry the photos aren’t better…*someone* took my camera to use at a Demi Lovato concert and didn’t bring it back in time. I had to use my phone’s camera. I did chill the wort down to 76F, using an ice bath.

Then I pulled a sample, oxygenated the wort for 2 minutes using a sanitized oxygen canister and “oxygen stone” set-up and pitched my Edinburgh Ale Yeast (that I harvested from a previous batch of cider). I had prepared a starter for the yeast in advance and it was very active. I don’t have experience with “pitch rates”, but I believe I have plenty of yeast cells for the job. Since the volume I wound up with is about 6 gallons, in a standard fermentation bucket, and I have seen this yeast ferment very aggressively, I went ahead and set up a blow-off tube  to keep from fouling the airlock.  The yeast was pitched around 5:10 pm. As of 9:45 pm, I’m hearing a little action in the blow-off tube.

Now, aside from the process, let’s talk about the sights, smells, and flavors! I made my own pumpkin pie spice blend, using cinnamon, cloves, ginger and nutmeg. I did freshly grate the nutmeg. Also, the ginger has been around along time, so I supplemented it with a little grated fresh ginger. I roasted a can of Libby’s Pumpkin, spread on some parchment paper, on a baking sheet, at 425F for about 30 minutes. It wasn’t particularly pretty, but it picked up a few dark spots from caramelization and lost a lot of water. I kept the pumpkin in a sanitized storage container until I was ready for it.

The wort took on a great brown color with a dark orange-ish shade to it. Really nice! And the aroma and flavor from the pumpkin and spices are very good, too. I think this is going to be a VERY good beer.

Using the hydrometer sample, the OG came in at 1.083 and, if the attenuation rate is accurate, the ABV will be 7.91%; however, in my experience, the SG isn’t going to stop at 1.023…so, the ABV will likely be over 8%. And, this sample was also the basis for the flavor and color evaluations.

An update on the ciders and muscadine wine: the wine is basically bulk aging and clearing nicely. I’ll eventually rack it…maybe a couple more weeks, and let it go a few months, before I bottle it. The Caramel Cider made with crab apples and Cripps apples is pretty much bulk, aging as well. It did have a little airlock activity going on for a while after racking…not regular or often, though. It has almost stopped now, I think, so I’ll probably rack that a final time in about a week. Maybe bottling in two weeks. The crab apple, pear and Cripps apples cider…no name for it yet…is still bubbling pretty regularly in the airlock. It probably won’t be bottled for a month.

I think I’m learning that it pays to take a little extra time. Excess sediment in the bottom of bottles seems to be messing with my carbonation after bottles have been around for a couple of months. And I like my ciders to have very good clarity…not as huge a deal for all beers, but some. (For instance, wheat beers are actually supposed to be a little hazy.) So, slow down…get it right. Give it another week. It can only help!

Update: 9/15/14  Getting very good action in the blow-off on the Samhain Pumpkin Ale. It hasn’t fouled and it isn’t quite what I have heard some describe as “Rhino farts”, but it is almost constant bubbling.

Update:  9/15/14  Opened the test bottle of the caramel cider to see what it’s doing. No carb at all. The ABV is a hefty 10.89%, though and the flavor is nice. Color is good. Finished product will be more clear.  Alcohol may have pushed the Edinburgh Ale yeast past its tolerance…may have to explore options, if I want to carb.

Caramel Cider tester bottle...no carb; lots of alcohol.
