Day 158 Yeast Harvest Fail, Try Another

 

Got my starter all ready and aerated. Pitched harvested Edinburgh Ale yeast...nothing.

Got my starter all ready and aerated. Pitched harvested Edinburgh Ale yeast…nothing.

I attempted to harvest the Edinburgh Ale yeast from my Scottish Samhain Pumpkin Ale, after I racked it to secondary. I collected some trub and tried “washing” it and adding it to a beaker of DME boiled with water for ten minutes. No luck after about 24 hours. So, I decided to pitch another expired yeast that I picked up after the yeast class I took awhile back. I shook a vial of American Ale yeast  and pitched it in the same starter beaker.

Overnight, it was showing signs of growth. I swirled it down a few times today.

Success with expired American Ale yeast.

This evening, I put the beaker in the refrigerator to crash it. Tomorrow, I’ll transfer it to a jar and keep it refrigerated until I need it. Actually, my next brew is likely to be a porter, so I will have to buy some yeast for that batch. Then, maybe I’ll use the frozen fresh hops I have to do  “wet hops” beer. That will require a little research to find an appropriate recipe to try.

Day 156 Final Racking for Caramel Apple Cider (Probably)

Should be the final racking for bulk conditioning of my Caramel Apple Cider.

Should be the final racking for bulk conditioning of my Caramel Apple Cider.

This is what will probably be the last racking for the crab apple/Pink Cripps apple cider that I have decided to call Caramel Apple Cider, due to the small addition of molasses and a cinnamon stick. It’s nice and clear now and I think I’ve managed to leave the rest of the small amount of sediment behind.

I had hoped to bump up the volume to 1-1/2 gallons, by boiling, cooling and adding 800 ml of water. There’s plenty of alcohol and I just don’t want to lose anymore volume.

I transferred the cider, by siphon, to a 2 gallon fermentation bucket, racking off of the sediment and trying to minimize oxygenation. I added the boiled water, cleaned my containers and refilled them.

Unfortunately, there wasn’t enough to fill the half gallon; so I wound up with the volume I started with, minus the sediment, plus enough for a hydrometer check and a nice sample for evaluation!

I measured the SG at 1.013, down from an OG of 1.102…even after the small water addition. That makes the ABV 11.68%. Incredibly, the aroma is fresh apple juice. The flavor is deceptively smooth and sweet, with a nice touch of caramel. The finish is a tummy warmer, though! Really, very nice.

Look at that color!

I have been trying to carb all of my ciders so far, but the ABV on this one has probably already overwhelmed the Edinburgh Ale Yeast and I don’t think carbonation would be an improvement in this case. I did have enough to fill a test bottle. The cider should be good for a couple of months, but I’ll check the tester in a couple of weeks.

Racked off the sediment and maintained volume for bulk aging. Again, look at the color! And the clarity.

Soon, it will be time to do the “final” racking for bulk aging on the muscadine wine and rack the crab apple/pear/Cripps apple cider to secondary.  And finally, my Scottish Samhain Pumpkin Ale should be ready for secondary sometime next week. So many good things going on and they all take so much time!  The pumpkin ale should be ready before Halloween and should be good (maybe better) at Thanksgiving.

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.

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”.

***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!

Nice color!

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.

Hydrometer sample...settling a little.

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.

Day 152 Started Another Batch of Cider

Washed and sorted crab apples. Over 20 lbs. Gotta use 'em!

Washed and sorted crab apples. Over 20 lbs. Gotta use ’em!

Realizing that I have a bunch of foraged crab apples left to use and the clock is ticking, I started another batch of cider today. I started with the juice from about 5 lbs of crab apples and then added juice from 5 pears, 3 Ginger Crisp apples and 4 Pink Cripps apples and a little bottled lemon juice to keep the apple and pear juices from browning too much. Altogether, I got about 3/4 gallon of juices.

I put that juice into a 5 gallon bottling bucket with the pommace from the crab apples, tied in a cheesecloth bag. I didn’t have enough cheesecloth on hand to fit the apple/pear pommace in, but that’s okay.

Juice, water, sugar, cinnamon, yeast nutrient, campden tablets and pectic enzyme.

I stirred in 5 lbs of sugar, 2 cinnamon sticks, 2 teaspoons of yeast nutrient, 2 crushed campden tablets and a 1/2 teaspoon of pectic enzyme. Then I added a gallon plus 6 cups of water and stirred. It was so close to 3 gallons that I decided to top up…just a couple of extra cups. I checked the SG and it’s around 1.110-ish. I’ll get the official OG tomorrow, before I pitch yeast. Sometimes the sugar isn’t completely dissolved at this point and the reading could be off. I sealed the bucket and set it aside.

My next step was to begin a yeast starter from my harvested Edinburgh yeast.

I boiled a 1.040 wort for 10 minutes made from light DME and chilled it to about 77 F.

I then added about half of the contents of my 1/2 pint jar of yeast slurry to the starter. I’m out of yeast nutrient, so I hope the yeast is healthy enough without it! I’ll see where the progress on the yeast starter is tomorrow morning.

Ready to build that yeast!

Update: 9/8/14   Cold crashed the yeast starter early this evening. About 9 pm, I drained off the excess liquid, opened the lid on the cider, removed and squeezed the cider out of the cheesecloth bag of pommace  and drew off a hydrometer sample. The OG is 1.096 at 72.9 F, so corrected =1.097. I pitched the Edinburgh Ale yeast, stirred and resealed the lid. I refrigerated the hydrometer sample to sip later. Very sweet, as expected. As of midnight, no visual on airlock activity. I will check it in the morning. Pretty sure it will be rockin’ soon. Starter was vigorous, as was the batch I harvested it from.

Update: 9/9/14   Airlock bubbles in latest cider batch at 10 a.m. Not very aggressive yet, but it’s going. By the way, tasting the hydrometer sample that I had chilled leads me to believe that this is going to be a nice clean, crisp cider after the sugar is converted.
