Muscadine Wine 2016

Time to make some wine.

Time to make some wine.

From the bucket of muscadine grapes that I picked from my niece’s grape arbor recently, I am making a batch of wine. I am starting with 11lbs, 5oz of grapes. You could use more or less, from what I have read; recipes vary greatly. I wouldn’t use less than 10lbs.  I have chosen a yeast that I hope will leave me with a “half sweet” wine. Not bone dry, but not too sweet. So, pulling together what I have learned from two previous batches of wine and the reseach I did for those, this is the recipe I’ve put together…..

Muscadine Wine

11 pounds, 5 oz Muscadine Grapes

3-4 gallons water (top up later, as needed)

sugar (up to 9lbs, dissolved in water for hydrometer or refractometer reading 1.090)

Cote des Blancs yeast

5 Campden tablets, crushed (1 per gallon)

5 teaspoons yeast nutrient

Acid blend to increase acid or

calcium carbonate (or potassium bicarbonate) to reduce acid (if needed)

(Acidity should be more than 0.55% and no more than 0.70%, there is a test kit available at wine/brew shops)

1-1/4 teaspoons Pectic enzyme

Make sure all utensils and containers are sanitized. I use a product called Starsan. Crush the grapes and add to a mesh straining bag (available at brew shops).

Pour the juice into a fermentation container (bottling bucket works well) and add the bag of grape skins/pulp.

Test the specific gravity of the juice. Use a calculation tool to figure out how much sugar to add for a 5 gallon batch. Dissolve the sugar in some hot water. Add to the juice/grapes and top off to 5 gallons. Verify the SG is in the correct range, around 1.090…it may require preparation of additional sugar/water solution. Add the crushed Campden tablets and yeast nutrient. Stir well and allow to sit for 10-12 hours, sealed and fitted with an airlock.

Test the acid and SG again. Adjust acid as needed.  Add pectic enzyme.  Rehydrate yeast as package directs. Pitch yeast and reseal.

Open the container and push the bag of grape must down and stir well with the juice…do this twice a day for the next 5 to 7 days. Check  for the SG to drop to around 1.030 and then remove the strainer bag. Squeeze to get any additional juice and then discard (or compost!). Rack to a carboy, leaving the sediment (lees) behind and continue fermentation until complete. Rack again a couple more times at 2 months intervals, until clear. Add 1 crushed Campden tablet each time the wine is racked. Stabilize and wait for any suspended yeast to fall. Bottle and age at least 1 year and up to 3 years.

Process this time: I crushed the grapes in a sanitized bucket, using a sanitized aluminum baseball bat.

I used a refractometer to check the juice SG and it came in at 1.058. I tried figuring out the sugar amount to add using Brewer’s Friend online tool. I found out that this process is called “chapitalization”. Unfortunately, I did it wrong. I mixed the sugar with the water and added it to the grape must. Once I added the water up to 5 gallons, the the SG was only 1.045.

So, I went back to the calculator tool and entered the new figures and recalculated the additional sugar needed. Altogether, the amount of sugar added was exactly 8lbs and the new SG reading is 1.091. Being off .001 is acceptable. I also added the 5 crushed Campden tablets and 5 teaspoons of yeast nutrient. Now it sits until tomorrow morning.

9/12/16: Okay., I added the pectic enzyme. Now we get to the part that I’m less confident about, but I’m going to do the best I can: measuring the acid. I have a kit that contains two chemicals. You measure and add one to a test tube (if it came with one, I’ve lost it, so I improvised), add some water. Then you measure some of the other and start adding it drop by drop to the test tube. When the color changes, without being able to swirl it clear again, you stop. You figure out how much you used and plug that into a formula and get a number that represents the acid content. Then you compare that to a range you should be in. That will determine if you need to raise the acid content or reduce it. From what I have read, muscadines are high acid, so I anticipated that I may have to reduce them…and I had not bought the right stuff to do that. Turns out, the acid is quite low. The 2oz of Acid Blend that I bought will not be enough. The figure I came up with was 1.2 ppt sulfuric (or 0.1875 % tartaric). Pretty much Greek to me, but I found the way to figure out the amount of acid blend needed was easier using the ppt sulfuric method. At 1.2 , I needed to add 1 oz to 5 gallons for each 1.1 increase. I had 2oz on hand, so that got me up to 3.4 ppt sulfuric. The range I need to be in for this wine is 3.9 to 4.2…a half ounce more would put be at the minimum, and an ounce would put me at 4.5, a little over. I need just under 3/4oz (4.225). 0.70oz will be 4.17. So, I need to find some acid blend today…my closest store isn’t open on Mondays, so I may have to drive a bit. I know this may sound like a bunch of confusing junk, but I’m trying to get a decent end product, so I’m going to deal with it. My biggest fear is that the wine will not have enough flavor…maybe I should have used more grapes? Crossing fingers. I will be pitching the yeast late tonight.

9/12/16: 9:00 p.m. Double checking test numbers after adjustments. ppT Sulfuric looks like 4.0 and % Tartaric looks like 0.625…these numbers are right where I would want them. The pH test is a little harder to judge. I was hoping it would be more than 3.0. The color on the test strip is defininately darker than 2.8 and lighter than 3.2, but there is no color reference in between. I guessed 3.0 before and maybe it’s a little darker…just hard to judge. I’m going to go by the acid test and assume I’m good. I did take another refractometer reading and got 1.086…ugh! So, I ran it again and got 1.091…whew! Starting the rehydration of the yeast and that will be pitched shortly.

9/12/16: 11.45 p.m. Yeast pitched. Cote des Blancs from Red Star. Decription: “Cote des Blancs is also known as Epernay II. It is recommended for Chardonnay, Riesling, mead and cider, as well as fruit wines, particularly apple. it imparts a fruity aroma in both red and white wines. A slow fermenter that works best between 50 and 80 degrees. This strain will not ferment to a dryness at the low end of the range, leaving residual sugar resulting in a sweeter wine.”

9/16/16: Removed grape must added a little water and removed hydrometer sample. 73.4 F and 1.040 on hydrometer = SG 1.041 . I’m going out of town and won’t be available to stir for a few days, so I went ahead and pulled the bag and drained.

Blueberry-Muscadine Wine, Adjustments and Yeast

24 hours after Campden Tablets added. Sugar, water, blueberries and muscadines.

Day 2 for the Blueberry-Muscadine Wine project…time to check the OG(Original Gravity), check the acid, add the yeast nutrient, pectic enzyme, and pitch the yeast. I started with the refractometer and got a couple different readings from the sample I took after stirring the must. (Of course, I sanitized everything that touched the must). Anyway, I felt like I was at the 1.090 range,but wasn’t confident, so I took a larger sample to check with the hydrometer later.

From the sample, I removed 3ml to test the acid. Following the instructions for the acid test kit, it looks like I was at a reading of 0.225; shooting for the range between 0.55 and 0.65. The recipe called for 2-1/2 teaspoons of the acid blend, but I needed the full 2 ounces that I purchased to get to 0.565. At the minimum of the range, but okay. I also added 2-1/2 teaspoons of pectic enzyme and 3 teaspoons of yeast nutrient. Added to the must and stirred in. Then I sanitized the yeast packet and scissors, and pitched the yeast, gently stirring it in.

I resealed the fermentation bucket and cleaned my utensils. Next, I used the rest of my sample to take an OG reading with a hydrometer. It looks like I have a reading of 1.110 at 71.6F, which adjusts for temperature (hydrometer calibrated to 60F) to OG 1.111.

I guess I should not have added all the sugar at once, so this is going to be a higher alcohol wine than I wanted, but that’s the way it goes sometimes. I just hope it tastes good! Montrachet yeast is supposed to have an alcohol tolerance of 13%, so if my FG comes in around 1.01-ish, it should be stopping anyway. (The color is good. The unfermented product is so sweet, it’s hard to get a real feel for flavor…but I think it will be good.)

***Update 8/27/15: Continuing to stir every evening, to break up the fruit floating at the top and submerge it all. Getting a nice steady action in the airlock. All appears to be on track. Obviously, it’s still extremely sweet; however, a small sip does have a little more fruit flavor than before, and a little taste of the fermentation.

Update 8/29/15: Stirred down the fruit in the fermentation bucket and noted that the appearance is pretty much the same as the above photos. I wonder if the blueberries that didn’t get crushed are fermenting? They don’t seem to be changing color…hmmm. The sample spoonful definitely has a flavor that has dropped in sweetness another notch.

Update 8/29/15: Continuing to convert sugar to alcohol…definitely a little more tannic feel in the mouth, more alcohol, and drier. I continue to note that the wine is still sweet, but what a difference! I like where this is going…at least, so far.

Update 9/2/2015: Now tasting more like wine and less like sweet, fermenting juice. Photos aren’t showing any real difference, but the flavor is telling the tale!

Starting Blueberry-Muscadine Wine

Day one: Blueberry-Muscadine Wine, ready for the 24 hour rest.

Day one: Blueberry-Muscadine Wine, ready for the 24 hour rest.

During the height of blueberry season, I got an amazingly good deal on a case of them. We ate some, I made an experimental, very small batch of jam, and then I stuck the rest in the freezer. Now that we are at the height of muscadine grape season, I have foraged several pounds of wild grapes. In doing a little research, I found this article: https://winemakermag.com/461-making-blueberry-wine-tips-from-the-pros  The majority of what I am doing comes directly from their recipe, so go read their article. If you are really interested in winemaking, you might like their magazine.

This is my second attempt at wine. You can find my entries on my first wine on this blogs entries starting about this time last year. It was a straight muscadine wine and I used Montrachet yeast for that batch…as I am using for this batch. The result, is a surprisingly dry, medium to light body wine that is a bit heavy on the alcohol (I overdid the sugar a bit), but not nearly as sweet as you normally find in wines made from muscadines. The color is between a blush and a red. I am pretty pleased with it. So, for my second wine, where I am going to change from the referenced recipe slightly, I’m using 3 pounds of wild muscadine grapes, instead of grape concentrate, and I’m using 11 pounds of blueberries. The blueberries were almost completely thawed, but still cold.

In preparing for the recipe, I did purchase an acid test kit ($8.95) and some blended acid powder from the local homebrew shop (LHBS). I also bought a package of Montrachet yeast. I did not add citric acid to the sugar water and I am not using the teaspoon of tannin. I am also substituting Campden Tablets, crushed, rather than the powdered sodium metabisulfate. The tablets are easy…add one per gallon, so five in this batch.

One tablet per gallon: 5 tablets. Easy!

I’m also skipping the potassium sorbate. I may be wrong, but the Campden Tablets are potassium metabisulfate, and I think using them covers it. (As well as the sodium metabisulfate.) Theses chemicals can get to be a little confusing for those of us who were Liberal Arts majors, rather than Chemistry majors! Anyway, I think I have things covered.

Today was all about crushing blueberries,

…and then adding the crushed Campden Tablets. I added enough water to rinse the crush bucket and bring the total volume to 5 gallons. (Top photo)

Tomorrow, I will deal with the yeast nutrient, pectic enzyme, test the acid and adjust it, if needed. Then I will pitch the yeast. After that, over the course of the primary fermentation, I will need to stir the “must” at the top of the bucket down into the liquid twice daily. I don’t plan on making a separate entry everyday, just to say that I stirred the must! I will document tomorrow, and when I rack, bottle, and eventually taste the wine. So, I’ve done the steps required for today. I’ll be back!
