The 2009 Merlot

The big news this weekend is the 2009 Merlot, which is not really a Merlot, but a blend of two cases of merlot grapes with one case of syrah grapes. I got the grapes at California Wine Grapes in Detroit proper -- one of my favorite stores.

This was a big advance for me in that it involved grapes and not grape juice as last year. My little grape crusher ground through the three cases pretty well, but the sorting out of the grape stems took a while. I have a little grape press on order. Hope it is here by next weekend. [My DW has a request in for hard cider.]

The  grape juice was sweet at 1.105 by density -- perfect. The juice did not taste satisfying though. The White Grenache juice for last year was like liquid heaven -- so great to drink. The Merlot will no doubt be better after fermentation since it is not so great today.

The recipe for the wine is:

72 lb California Merlot grapes
36 lb California Syrah grapes
1.25 t potassium bisulfite
10 gram of pectic enzyme

Allow to sit overnight

1 packet of Montrachet from Red Star

The plan is to ferment until Friday, then:

Malto-lactic bacteria

Press the grapes on Saturday, and move to the secondary fermentors, which are glass demijohns.

December 30, 2010 Update

I tasted this wine, and it was too acidic in flavor. I tried to measure the pH, and my (cheap little) pH meter did not read correctly. I added 1 gram of potassium carbonate per 750 ml bottle, and allowed the wine to age. 

This showed a bubbly reaction as the salt dissolved, and the carbonate bubbled into the air as carbon dioxide. The potassium ion is supposed to precipitate with tarterate ion and settle to the bottom. The wine is less tart than it was.

Non-Fermenting Sugars

I am toying with making a Hard Cider or sweeting some part of my 2009 Cherry wine. While I think that Spenda, sucralose, is an interesting idea, it is shockingly non-traditional, and I don't really like the idea of adding chlorinated chemicals to my wine.  [Of course I add it to my coffee, but -- well never mind.]

Spenda would work because it sweetens, but yeast can't digest it, so the  wine will be sweet to the taste rather than extra hearty.

The common solution is lactose, milk sugar, which is at right. It is notable because about 35% of the world's adults can't metabolize it, but then yeast can't either. It also isn't that sweet. Lactose is at right.

Another choice is malto-dextran, which is the main ingredient in corn syrup. It has not been degraded enough to ferment.

An excellent resource is this site from Aussie Home Brewing in Brisbane.

2009 Blueberry Wine and Wine Update

It's been three weeks since I started the blueberry wine, and I racked it for the first time today. I also removed it from its oversized demijohn and put in a three gallon carboy, where it will be for a while.

The flavor has changed a great deal in the last three weeks. The last remaining sweetness is gone. The wine is very fruity, very dark in color, strong tannin flavor, light in alcohol, very yeasty, and a little too sour. The color has changed and it is less red. It was more red than my cherry wine for a while.

I checked the pH and it was 3.2 by pH paper, which is about normal. I bought a little handheld pH meter and a set of standards, but I have set it up yet. I decided that regardless of what it was, it was too early to adjust it. I will wait for a few months before doing anything.

=======================================================================

Update on other wines:

It's been five weeks on the 2009 cherry wine -- so far so good.

It's nearing 10 months on the 2008 Merlot. I am going to have to transfer it out of its demijohn soon to make room for this year's grape wine. I am hoping to get petite Syrah grapes. If I do a white, it will be a Riesling.

I have been drinking my 10 month old 2008 White Grenache. After much work, I have gotten it to clarify with a bentonite addition. I like it better now that it is clear. I like it; it is a fruity simple wine -- not so complex.

Racking the 2009 Cherry and Blueberry

2009 Cherry Racking

It has been two weeks since I made the Cherry wine, and the sugar content is low. I can tell by the absence of sweetness -- I did not bother to measure it. I racked the wine a second time and took out about a gallon of lees.

I am worried about it. The sweetened cherry juice was delicious, but it tasted a bit like cherry cough syrup. Now that the sugar has fermented, there still is a distinct cherry cough syrup flavor. The wine seems to be on the strong side since I overshot the sugar at 1.12 rather than 1.08-1.09 like I wanted. I will worry about what to do with that later after the flavor matures. I probably will blend it with a white grape wine.

The cherry wine is very dark - as dark as my 2008 Merlot, and only slightly redder.

2009 Blueberry Wine -- First Racking

I measured the density (specific gravity) of the primary fermenter and got 1.022. This is pretty good, but I would have liked it to be lower after six days. I am concerned about spoilage so I transfered it to an oversized demijohn.

The flavor is pretty good right now, very fruity, but it is also sweet since the fermentation is not done. Hopefully it will keep going in the secondary fermenter.

At right is the partially fermented juice in the primary fermenter prior to racking. The color is redder than my cherry wine.

2009 Blueberry Wine and Recipe

I was at the store and the blueberries were $1.79/lb, which is a great price for grocery blueberries -- about what I paid for the cherries. So I decided it would be fun to try some blueberry wine -- why not?

I passed the blueberries though a manual "food mill" -- really a slotted funnel that the berries were pressed though with a funnel. I added both the juice and the skins. These berries were pretty clean, so there were very few stems or leaves.

Blueberry Wine Recipe

12 pounds of blueberries, crushed
2.5 pounds of apples, peeled, cored, and made into apple sauce
7 pounds of sugar
2.5 gallons of boiling water
3/4 teaspoon metabisulfite
1.5 teaspoons yeast energizer
1.5 teaspoons pectin enzyme
Levlin 71B 1122 yeast

I actually used 3/4 t yeast energizer and 1.5 t yeast nutrient so I could use up my yeast nutrient.

2009 Cherry Wine: in the secondary fermenter

The cherry wine fermentation took off after the first day, and the sugar disappeared. I let it go five days and filtered it through a nylon bag filter that I got at the wine store. I put it in an oversized demijohn, because I don't have one that fits.

I intend to wait a few more days and then put it in my three gallon carboy, and a gallon jug.

The top picture is the bright red cherry juice. The bottom picture is the five day old cherry wine. The change in color is real.

See the wine recipe posting.

Bentonite Clarifies the White Grenache

I am thrilled to report that 4 grams per gallon of Bentonite clay has clarified my White Granache wine. See the post below for the cloudy wine pictures.

Bentonite is a smectite clay with negative and positive layers. This means that it can grab a wide variety of proteins and drag them to the bottom of the bottle.

I dumped up all of my bottled White Granache, and put them in gallons.

I took the four grams of clay and added water drop-wise with stirring in a small cup-- like making a white sauce, and then I poured the mixture into the bottle. This helped the clay floated slowly through the wine rather than floating on top or sinking immediately. The slow stirring is important.

Now after six days the wine is all clear. This is a much better result than simply sprinkling the bentonite in the straight from the bottle. It also worked better than the Isinglass or the amylase, which did not work at all.
