Blackberry Wine 1.0

Adventures in Homebrewing had 96-ounce cans of Blackberry Wine base on sale for $10, because they were past the sell-by date.  I decided to chance it and buy two of the cans to turn into blackberry wine.  When opened, the cans smelled perfectly fine, so I think the wine is going to turn out well.  We'll see.

Ingredients (per 5-gallon batch)

1 can of Vintner's Harvest Blackberry Wine Base
8 pounds of cane sugar
3 tsp. Citric Acid
4 tsp. Yeast Nutrient (DAP + Fermaid O)
2.5 tsp. Pectic Enzyme
1/2 tsp. Wine Tannin
1 packet CR51 Vintner's Harvest wine yeast
Enough RO water to reach 5 gallons in the fermenter

  • Original Gravity: 1.086 SG for one batch, 1.077 SG for the other
  • Final Gravity:  0.988 SG estimated
  • Batch Size:  5 gallons per batch
  • ABV:  13.5% estimated
  • Fermenters Used:  Two 7.5 gallon SS Brewtech Brewmaster Buckets
Preparing the must was pretty straightforward.  I heated three gallons of the RO water to about 120F and began dissolving the sugar in it.  When the sugar seemed dissolved, I added the Citric Acid, Yeast Nutrient, Pectic Enzyme, and Wine Tannin.  I then pumped it into the fermenter and topped off with room temperature RO water to the 5 gallon mark.  The yeast was pitched and the fermenter contents stirred with a sanitized steel spoon.

Post-Brew Notes and Observations

12/23/2020:  The batch filled to the 5-gallon mark had an original gravity of 1.076 SG.  The other batch was filled to around 4.75 gallons and had an original gravity of 1.086 SG.  I was surprised there was so much actual fruit in the container (see photo below).

12/24/2020:  Fermentation is underway.  By noon, the gravity in one batch had dropped to 1.066 (from 1.086) and the other from 1.076 SG to 1.047 SG.  The primary difference between the two was that the second batch (1.047 SG) was a few degrees warmer from the start.

12/25/2020:  One batch (the one starting at 1.076 SG, which we'll refer to from here on as the Blue batch because it has a Blue Tilt Hydrometer in it) is down to 1.038 SG and 71F (5.4% ABV).  The other batch (which we'll refer to as the Red batch) is down to 1.063 SG and 66F.  I'm planning to attach a fermentation wrap heater to both batches later today to hold them at the same temp for the remainder of fermentation.  According to the manufacturer, the best results are obtained with this yeast at 61-75F.  I'm planning to aim for the middle of that range, or 68F.

12/26/2020:  The Blue batch is at a gravity of 1.037 SG today. The Red batch is at 1.064 SG.  I added temperature control to both this morning, aiming for 68F in both fermenters.  As of this writing, the Red batch is 68F and the Blue batch is at 67F.  I'll need to bump them up to the desired temps soon.  Since my temperature probe takes a while to settle in, I wanted to give both controllers time to establish a solid base reading before tweaking temperature settings.

12/27/2020:  The blue batch is down to 1.026 SG today, and the Red batch is at 1.055 SG.

12/29/2020:  The blue batch reads 1.012 SG today, and the red reads 1.035 SG.  Both are being held at a temperature of 72F.

01/02/2021:  The blue batch reads 1.003 SG and the red reads 1.013 SG.  Both continue to hold at 72F.

01/12/2021:  The blue batch is reading 1.000 SG (and has for a few days).  The red batch is reading 1.005 SG.  Both continue to hold at 72F, though I plan to disconnect temp control from the blue batch today since it seems to be finished fermenting.

01/15/2021:  The blue batch has been holding at, or just below, 1.000 SG. I dosed the wine with Turbo Clear to strip out the yeast and sediment, clarifying the wine.

02/27/2021:  I bottled the wine today, using a mix of Grolsch style bottles and standard beer bottles, since they were what I had on hand (and I don't own a corker).  The wine had a nice flavor and was quite clear.  There was a clear, but not strong, blackberry note to it and a red-wine-like tannin note.  I am looking forward to seeing what others think of it once the pandemic is over.

Grainfather Specifications for BeerSmith, Beer Tools Pro, and Other Software

Recently, I've been trying to "dial in" settings in BeerSmith and Beer Tools Pro so that I can do a better job getting my actual brewing results to match up to the figures in the software. Below are some of the figures I've worked out with my US Grainfather. Given manufacturing variances and possible measuring errors on my part, these might not match exactly to yours, but hopefully they're close enough that it will help you. BeerSmith Equipment Profile: Brewhouse Efficiency: 83% (based on my experience, yours may vary) Mash Tun Volume: 8 gallons Mash Tun Weight: 8.82 pounds Mash Tun Specific Heat: 0.12 Cal/gram-deg C Mash Tun Addition: 0 gallons Lauter Tun Losses: 0 gallons Top Up Water for Kettle: 0 gallons Boil Volume: 6.25 gallons Boil Time: 60 minutes Boil Off: 0.40 gallons per hour Cooling Shrinkage: 6% Loss to Trub and Chiller: 0.53 gallons Batch Volume: 5 gallons Fermenter Loss: 0.40 gallons (yours may vary) Whirlpool time: 0 minutes B

Yellow Label Angel Yeast vs. Typical Brewing Yeast

I currently have my second batch of rice wine fermenting with the "magical" yellow-label Angel Yeast from China, and wanted to share some of the more unusual aspects of using it.  If you've never seen or used this yeast, I suspect you're not alone.  It ships in a 500 gram package that looks like this: What makes it "yellow label" is that yellow box you see in the upper left corner of the package.  This implies that it's yeast for distilling (though you do not need to have a still or distill the output to use it).  As I understand it, inside the package is a mix of yeast and other materials which will convert starch into sugar and directly ferment it, without the need for a traditional mash step.  This can radically shorten your brewing time.  For my most-recent batch of rice wine, I heated 3 gallons of water to 155F, poured it over 13+ pounds of uncooked rice straight out of the bag, let that soak for an hour, rehydrated some of this yeast in warm water,

Things I've Learned Brewing with The Grainfather, Part 2

In the last post, I shared an overview of The Grainfather, recommended equipment to use with it, and an overview of the brewing process.  In this installment, I'm going to talk specifically about mashing and sparging. Having brewed over a dozen batches with it, I'm finally becoming very comfortable with the device, the mash process, and how to get what I want out of it. I don't consider myself a "master" of it yet, though. For those who have never done all-grain brewing, I want to provide a quick overview of the mash process itself. Mashing - With or Without The Grainfather The goal of mashing is to turn the starches in the grain into sugars. More specifically, you want to turn the starches into a mix of fermentable and unfermentable sugars that provide the flavor profile associated with the beer you are brewing. A sweeter beer might warrant more unfermentable sugars. A more dry beer will demand few unfermentable sugars. To a great extent, controlling the
