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 142 Ginger Beer and Citra Belle Saison updates

I drew just a couple of ounces from the Citra Belle Saison…the flavor has approved since I racked to secondary on an ounce of Citra hops. Needs a couple more days…should bottle Sunday or Monday.

The ginger beer that I bottled previously hasn’t really taken off in the carbing department. In fact, I considered dumping the bottles back into the “second runnings” batch and combining them. However, I checked a bottle yesterday and it had a small amount of carb. Not much, but enough that I have decided to leave the bottles and watch them to see if/when they need to be pasteurized.

The “second runnings” batch is taking a long time to really get fermentation going. I had it off the heating pad for awhile. When the weather cleared, I gave it some time in the sun for a couple of days, but then the temp dropped, so I put it back on the heating pad and covered it with the space blanket and the fermentation picked back up. It’s coming along slowly, but today was the first time that I believe I detected alcohol in the aroma when I opened the lid. So, while a longer process than I anticipated, the plan remains as originally envisioned: virgin batch is to be non-alcoholic and the “second runnings” batch will be fermented out for an alcoholic version. No photos for this update…nothing really interesting to see,  just an update.

Additional update 8/16 10:15pm : I guess I was wrong on my second runnings ginger beer. I just took a SG reading and it looked like 1.066 when corrected for temperature and the OG was 1.062. So, either the the sugar is increasing in this bucket (not likely) or one of the measurements was off. I’m betting tonight’s measurement could be a tad off, due to some bits of ginger solids in the hydrometer sample. Would that affect it? I don’t know…seems like it might. At any rate. I’m thinking that there is no fermentation really going at it here, so I’m making an executive decision to add 1/8 teaspoon of dry Champagne yeast to the mix, after I strained it through cheesecloth and made sure I have at least a gallon of liquid left, which I do. With Champagne yeast at work, I will have to keep a close eye after I bottle it and definitely pasteurize; otherwise, the yeast won’t stop until it is bone dry and bottle bombs!

8/18…I had seen some activity with the addition of Champagne yeast to my Second Runnings Ginger Beer, but it seems to have stopped. I checked the temperature and it was over 100F. I guess a two gallon plastic bucket heats a lot more on a heating pad and wrapped in a space blanket than a 6 gallon glass carboy and I’m sure the yeast must be dead. I Googled and found “This strain tolerates fermentation temperatures ranging from 50° to 86°F….”.  So the plan is to get the temperature down and pitch the yeast again…and no additional heat. The house is usually around 74F this time of year. Still trying! And I missed buying bottles yesterday and the home brew shop is closed today. I guess my Citra Belle Saison is going to dry hop a little longer that anticipated.

Day 140 Pasteurizing Tepache, Bottling Ginger Beer, Racking Cherry Belle Saison

Pasteurizing.

Pasteurizing.

 

I decided to go ahead and pasteurize the Peach-Pineapple Tepache. The test bottle was pretty hard. The sample I tasted was lightly carbonated, but I didn’t want to take a chance of overcarbing. I filled my pressure canner body, with the false bottom, with hot water. I used the bottles to be pasteurized as a measure of how much water to use. This served an additional purpose: warmed the bottles a little before pasteurization. I removed the bottles and put the pot on the stove. I brought the water up to 180F and removed the pot from the heat, placed the bottles in, partially covered with the lid, and set a timer for ten minutes.

My next project was to bottle the non-alcoholic ginger beer.

I strained the solids out through a cheesecloth and the used a siphon and bottle wand to fill cleaned/sanitized bottles and capped them. They will need to carb for at least 24 hours and then be pasteurized.I believe this batch is too sweet, but I followed the recipe. I put the ginger and spices back into the fermentation bucket. Since they only sat for 24 hours, I feel like there is more flavor to give. So, I’m making a “second runnings” ginger beer that I am going to allow to ferment and produce alcohol.

I added 4 cups of water and measured the OG at 1.062. I may reduce the sugar a little in future batches.  Anyway, I put the bucket back on the heating pad and wrapped it in the Space Blanket.

Next, I got a quart of Culligan bottled water and boiled it for ten minutes and, while it was boiling, I siphoned the the Cherry Belle Citra Saison into a 1 gallon glass carboy for a tertiary stage, leaving behind the cherries and a little sediment.

The color is really nice and the cherry flavor is good. I think this will benefit from a little aging. After the boiled water chilled in the refrigerator, I topped off the saison to a gallon. It didn’t take the whole quart…maybe a pint. I’ll let this settle for a couple of days and then bottle it.

As for the main batch of Belle Citra Saison, I did an SG check and it was 1.000 at 83F. That’s 1.003, corrected for temperature. This should be ready to rack to secondary any time. When I do rack it, I’ll be dry hopping with an ounce of citra pellets.

Day 135 Micro-Batch Cherry Belle Saison

Micro Batch Citra Saison

Micro Batch Citra Saison

I currently have a Citra Saison batch in a 6 gallon carboy going through primary fermentation. When I brewed that batch last Monday, I wound up with an extra gallon. I decided to process that in a 1 gallon carboy and create a “Micro Batch” of Citra Saison with vodka soaked cherries. Since this batch is made using a Belle Saison yeast that I harvested from my Hi-Nelson Saison w/Hibiscus. I’m calling the micro batch “Cherry Belle Saison”. The full batch was hopped at 30 minutes and 10 minutes with Citra hops. The big carboy isn’t ready to rack yet, but will get dry hopped with Citra when it’s time.

This micro batch will not be dry hopped…I’m thinking that the dry hop would be too much to let the cherry flavor come through. Also, hop flavor fades over time and I think I may age the micro batch a little longer than the main batch…maybe 4 or 5 months. I’m anticipating getting about 9 bottles out of this batch and I’ll probably taste one after about a month, so I should have 8 bottles to age.

This carboy was looking pretty clear and it doesn’t really need to wait for the big batch. Plus, I’m pretty sure that the natural sugar from the cherries is going to restart the fermentation process, so I didn’t really have to make sure that it was completely done with primary fermentation. Finishing secondary and a brief tertiary stage will be important for this one.

The cherries, 1 pound, were soaked in about 1/2 cup of vodka and kept in the freezer since Monday.

I added those to a two gallon fermentation bucket with the vodka, and racked the small carboy of saison onto them.

The I sealed the bucket and added an airlock. I put the bucket back on the heating pad and Space Blanket wrap with the big batch and I’m done for tonight, except for the clean-up.

I got a hydrometer sample from the bottom of the 1 gallon carboy and checked it. It was 1.003 at 84F, so, corrected for temperature variation with the hydrometer, it comes out to 1.006 SG.  I’ve stuck the sample in the fridge to cold crash, so I can check the clarity and flavor later. The clarity looked pretty good before I racked it. After racking, I’m just under a gallon. DSC05204

Day 134 Status Citra Saisons and Diet Root Beer

Switched back from blow-offs to airlocks

Switched back from blow-offs to airlocks

A quick update on my current projects: 1) Diet Root Beer. I prepared a replacement cap for my test bottle, I opened the tester and heard a slight CO2 escape. I poured a very small amount in a glass. There were very few bubbles. The soda was obviously undercarbed, but had some…hopefully, that will continue to increase! The flavor was strong on the root beer and not overly sweet, but it does have a little “diet” aftertaste. It’s okay, though, for the trade-off on sugar. I’m just hoping it carbs enough! Next time, maybe a little sweeter. I may have to find a way for a little more sweetness and a little less aftertaste without upping the sugar too much.

2) I switched back to regular airlocks for the Citra Saisons this afternoon. The action seemed to have relaxed sufficiently. Still on the heating pad on “low”  and wrapped in the Space Blanket. The main batch is bubbling about every 8-10 seconds and the little bonus gallon, that I’m going to rack onto vodka soaked cherries, is at about 18-20 second intervals. Looking good! A lot of trub…I’ll probably get 4-1/2 to 5 gallons out of the big carboy and 2/3 gallon on the small one, but they should be good!

3) Moving the Hi-Nelson Saison w/Hibiscus to storage. They were bottled on July 27th. Should be a couple of weeks before I open one and a month before I expect them to really be ready.

Day 133 Brew Day! Citra Saison with Harvested Yeast Starter

Setting up for brewing

Setting up for brewing

This was an uncharacteristic brew day for me. I usually don’t brew on weekdays. Certainly not Mondays. But the starter I had hoped to pitch in a Citra Saison pushed me back a day. I have never harvested yeast and never made a starter before now and I was afraid that the starter was going to be too weak. I worked out a boost for the starter (see previous post) and moved the brew back a day.

After I got everything all set up and ready to go, I got my BIAB (Brew In A Bag) in place and heated my strike water, 6 gallons.  The goal was 150F…water went to 154F and I mashed in. The water only dropped 1/2 degree though. I turned off the heat and made a run for ice. When I returned, the temp was 150.2F. Over the next 45 minutes, I tried my best to maintain the target temperature of 150F; however, it was probably more consistently in the 153F range.

After the BIAB (Boil In A Bag) steep and "sparge"

After the BIAB (Boil In A Bag) steep and “sparge”

Here is where I will talk about my changes to the original recipe that I found online. First of all, I decided to do Pale Malt 2 row, instead of Pilsner. Two reasons: sale on Pale and 60 minute boil instead of 90 minute. (Some recommend Pilsner boil for 90 to reduce chance of off flavors.) Next, I added 1 teaspoon of Irish Moss at 15 minutes left in the boil to aid clarity. I also realized that I had forgotten to buy 1 pound of Belgian Clear Candi Syrup…made a run to the closest brew shop, only to find that they are closed on Mondays. Aaaargh! So, I substituted a pound of raw North Carolina honey, instead (at 10 minutes left in the boil). I am also planning on adding a dry hop step to secondary. The recipe calls for Citra hops to be added 1/2 oz at 30 minutes and 1/2 oz at 10 minutes left in the boil. I am a big Citra fan, so I am going to add an ounce in secondary.

Okay, back to the procedures: After the 1 hour mash in, I did my usual “tea bag” style dunking and draining of the bag, using a large pizza screen over the pot for support. I then set up a bottling bucket with 2 gallons of sparge water at about 150F and used the spigot with some hose on it to do an improvised sparge. I’ve used this method that, as far as I know, I made up, a few times and I think it helps a little. This left me with a rather full kettle, so the boil was a challenge and had to be monitored pretty carefully.

The pizza screen was helpful in the tea bag style sparging and in helping keep bugs and debris out.

I set timers for my additions and all of that went well. Did my usual ice bath chill and managed to get the temperature of the wort down to about 90F, pretty quickly…good temperature for Belle Saison yeast.

Now, I wanted to use my glass carboy for primary fermentation, so I could have a visual on activity. The problem is getting 7 gallons of wort from a stock pot into a heavy glass 6 gallon carboy using a funnel. I struggled and spilled a bit, trying to figure out a grip and pouring into a small target that filled quickly. I could see that wasn’t going to cut it, so I poured about 3/4 of the wort into the bottling bucket I had used for the sparging, and then went through the spigot and hose into the carboy. Obviously, I was going to have too much wort, so, rather than toss it, I grabbed and sanitized a one gallon carboy and put the rest of the wort into it.

I used my oxygen tank to oxygenate the big carboy for two minutes and the little one for one minute. Between the refractometer reading of 1.048 and the hydrometer reading, corrected for temperature to 1.044, I’m  going to estimate 1.046 OG.* Rather than try to decant my yeast starter, I decided to swirl the flask to mix it well and pitch the whole thing…guesstimating some for the smaller batch. The starter wort used pale DME (Dry Malt Extract), so it shouldn’t hurt the flavor of the beer. The recipe doesn’t give a projected FG, but Belle Saison is pretty aggressive, so I’m betting on around 1.002 for the big batch. So, maybe a 5.78% ABV? I would be happy with that.

Here's the volume of wort I wound up with.

Here’s the volume of wort I wound up with and my flask of starter yeast.

I have no clue what to expect for the one gallon batch, because I’m going to add one pound of fresh cherries to secondary fermentation, rather than dry hopping it, and the sugar in the cherries will surely kick fermentation back into gear. I currently have the whole cherries in the freezer with some vodka. When it comes time to rack the small batch, I’ll crush the cherries into the vodka a little to release some juice and add it all. I’ll probably use a 2 gallon bucket that I use for ciders to do the small batch secondary, so I have a wide opening with which to work.

The recipe calls for a week each for both primary and secondary; however, my Hi-Nelson Saison needed a little over two weeks for primary and then a week for secondary. And the small batch may go longer in secondary. I’ll probably even rack the small batch to a tertiary stage to clarify once it’s off the fruit. Probably back into a glass carboy again so I can judge the clarity.

The big question mark is whether my yeast starter was going to work. The yeast was pitched at 3:15 p.m. and the carboys were set on a heating pad, on the lowest setting. At 6:30, there was no activity evident and the glass felt pretty cool.

I upped the heating pad to medium and wrapped the carboys in a “Space Blanket”. By 9:30 p.m., they were both chugging along in the airlocks…not violently, but good, frequent bubbles every second or two. Success!!! Woo hoo!!!

Heating pad AND Space Blanket...now we're chugging!

I cold crashed the hydrometer sample just to see what it looks like and how it tastes at this stage. Obviously malty and sweet at this point, but it seems like it will be nice and clean, light bitterness and the hops should shine through on the main batch and the Belle Saison should add a little spice and funk. The little cherry batch should be really interesting!

*I also let this sample come to room temperature and took another hydrometer reading. at 74.2F and 1.046, adjusted to 1.047, so that will be my new OG to go with. I read the hydrometer with no contacts or glasses and it was much easier to get a good read, so I feel confident with that figure. (An additional refractometer reading, of course, calls it 1.048, so…whatever!) Could be around 6% ABV…anywhere in that  5.75 to 6.05% range is close enough.

Update: Okay…the following morning, the airlocks were fouled. I quickly set up blow offs and the yeast is going at it, big time! Definitely had enough yeast!
