Wines I'm Making: 2010 Cabernet Bottled/2011 Cabernet Pressed

Yesterday (November 7) I put capsules and labels on the 2010 Cabernet Sauvignon/Cabernet Franc wine I bottled yesterday. The day before, I pressed the 2011 Cabernet Sauvignon/Cabernet Franc and transferred it to glass carboys. Yesterday, Monday, I inoculated the new wine with malolactic bacteria to start the malolactic fermentation. Malolactic fermentation converts malic to lactic acid, a routine procedure in making red wines. Malolactic fermentation is a bacterial fermentation that requires a little more warmth than the yeast-based primary fermentation. So, the carboys are wrapped in blankets in the living room with a small electric blanket between them to keep the temperature up. Malolactic fermentation is somewhat mysterious. It can take anywhere from three weeks to two months and it doesn't always show outward signs. The only way to really know what's going on is to do a paper chromatography test that shows the levels of tartaric, malic, and lactic acid in the wine. Sometimes tiny bubbles form at the top of the wine, indicating that some sort of activity is going on, but not always. I tend to take it on faith that the process is under way, but I'll be looking for signs the next couple of days.

The Sangiovese rosé fermentation is just about finished. I'll need to rack that wine off the gross lees soon--probably tomorrow. The wine is beginning to clear. Less carbon dioxide production means the suspended material is beginning to fall out of the wine. I think we'll end up with a very pretty pink. The harvest was so late this year, though, that I don't think the wine will be ready by Thanksgiving, as it usually is. We'll have some for Christmas though.

The 2010 Cabernet is finished now. I put the back labels on today. I'm pleased with the labels I designed for both the front and rear of the bottle. I decided red capsules would look best with the deep red of the front label. The capsules are on. The wine is ready to drink. The samples I tried while bottling and with dinner after bottling was done suggest the wine is good despite the cool summer last year. It seems a little soft compared with other years, which suggests it may not age as well as other vintages, but only time will tell.

Wines I'm Making: 2011 Fermentation (November 5, 2011)

The 2011 Cabernet is mostly done fermenting. The cap is no longer rising, my punch-down tool has started sinking into the liquid (rather than riding on the cap), and the liquid tastes like wine--there is no longer any trace of sweetness. Just to be sure, I tested the wine using my hydrometer and got a specific gravity reading of 0.996, which indicates fermentation is mostly finished. I will probably press the wine tomorrow, although I had planned to bottle the 2010 Cabernet tomorrow. We'll see if there's time to do both.

I crushed the Cabernet grapes on October 24 and inoculated them with yeast on October 28, so the fermentation took only eight days, although the wine has been on the skins for 12 days now. Eight days is faster than some fermentations I've done, and usually at warmer temperatures (because earlier in the year). I'm not sure why this cooler fermentation was shorter, but every fermentation is different.

The Sangiovese rosé continues to bubble gently. Fermentation appears to be continuing. The intense red of the liquid just after pressing has softened considerably. The wine is now a nice medium pink, but it's hard to  know exactly what color the wine will be until the CO2 gas stops rising and the suspended matter begins to fall out of the wine. So far, the rosé has been fermenting for 12 days.

Wines I'm Making: 2011 Wines

Our Sangiovese rosé is now in its fifth day of fermentation. The container is fizzing lightly and a great deal of the deep color present initially has already disappeared to leave behind a pretty pink. The color of the finished wine won't be apparent for another week or two, but so far it looks good. The fermentation is proceeding slowly (by design). I expect it to last another seven or eight days at least.

The Cabernet Sauvignon/Franc is also undergoing fermentation, soon to enter its third day. I added the yeast on the morning of Friday, the 28th. I'm punching down the cap of skins that rises on the surface four times a day, as I usually do. The liquid is a deep, inky purple. As I did a four-day soak before adding yeast, the skins have been giving up color for nearly a week. Fermentation will probably last another eight days or so. The 2011 wines are moving along nicely.

 

Wines I'm Making: Harvest 2011

I decided today was the day to pick our grapes. The somewhat warmer weather of the past few days seemed to be doing little to raise sugar levels and I was beginning to see signs of mildew in a few clusters, so there seemed little reason to wait further. It was a small harvest--having lost a great deal to animals this year. We picked 20kg of Sangiovese, or 44lbs and 43kg of Cabernet Sauvignon and Cabernet Franc, or 94.6lbs. This is the latest we've ever picked. I waited in the hopes of getting the sugars up, but it just wasn't warm enough. The unfortunate timing of the rain we had in October complicated things. Some berries swelled with water and split, allowing mold to begin to form. All in all, the grapes look pretty healthy, but mold can take hold very quickly if left unchecked, so better to get the fruit in.

After crushing and de-stemming the grapes, we ended up with 4.75 gallons of Sangiovese must, which I sulfited lightly with three Campden tablets to add about 41ppm of sulfite. The must tested at 20.7 Brix by refractometer and a specific gravity of 1.084 by hydrometer. The pH tested at 3.35. pH squared times Brix equals 232--not at all bad for making a rosé. I took the measurements at 63 degrees F, so I didn't bother to adjust the hydrometer reading for temperature (according to my books, hydrometers are usually calibrated at 59 degrees F, or 15 degrees C).

We got about 10.5 gallons of Cabernet must, which I sulfited lightly with seven Campden tablets (about 43ppm). The must tested at 22.6 Brix by refractometer--somewhat lower than I was hoping for, but respectable, and at a specific gravity of 1.094 by hydrometer. The pH was 3.42. pH squared times Brix yielded 263, which is right about where it ought to be.

I will press the Sangiovese already late tomorrow morning, after about 18 hours on the skins, which has seemed about right in the past. I will then inoculate the pressed juice with yeast and set it aside in a chilly place (either in the garage or outside) for a cool, slow fermentation. The Cabernet will get a soak for a day or two or three before inoculation. And so our 2011 wines start their journey.

Wines I'm Making: Waiting to Harvest 2011 Grapes

I did a proper test of a representative sample of grapes in our small backyard vineyard today. It seems we still need to wait. I'm nervous only because I'm afraid whatever has been stealing grapes will steal too many before I get a chance to pick. Yesterday I checked the nets carefully again and closed a few small holes. I don't know if they were new holes or holes I'd missed before.

The Cabernet grapes tested at 22 brix and a pH of 3.13. The Sangiovese, from which we will make a rosé, as usual, tested at 20 brix and a pH of 3.10. One school of thought says grapes for red wine should be picked when the square of the pH times the brix reading is around 260 and that whites grapes (or red grapes for rosé) are optimally ready when that formula yields 200. Using this method, the Cabernet grapes are at 215.5, the Sangiovese at  192. If the grapes were at the targets I usually use (the Cabernet at 24.5 brix, the Sangiovese at 22 brix), the Cabernet would be about right if by that time the pH had risen a little--say, to around 3.3. The Sangiovese grapes are closer. In any case, I think waiting is the right decision for both. So far, there is no sign of mold or other damage to the grapes, although I did notice a yellow jacket in a grape with a broken skin. Vigilance is in order. What we really need is a few days of temperatures in the upper 80s (which may be wishful thinking--the 10-day outlook is for cloudy skies and temperatures mostly in the mid-70s). The past four days of dry warmth have done little to raise sugar levels. The waiting game continues.

Wines I'm Making: Still Waiting to Harvest 2011 Grapes

It's sunny and warm today. It was sunny yesterday. If this weather holds, we may make some decent wine after all. In 2010, we harvested grapes on the 12th (Cabernet) and the 16th (Sangiovese) of October at rather low sugar levels (only 17 brix in the case of the Sangiovese, at a better 23.5 brix in the case of the Cabernet; ideally, I like to pick the former at about 22, the latter at about 24.5). The rosé in 2010 was light and without the rich flavors that made the 2009 so good. Happily, sugar levels are already higher than they were last year (the Sangiovese is at about 20 brix, the ripest Cabernet berries today tested as high as 24 brix). Now that I seem to have foiled the critters for the time being, I'm content to wait and let the grapes fully ripen. If it rains and turns cold again this weekend, I may have to think again, but early next week may be the right time to harvest anyway.

Wines I'm Making: Grapes Coming Along Nicely (2011)

Having recently added nets and raised the level of the electric fence around our grape vines, it's now been about a week without any further damage or losses to the raccoons or possums or whatever it is that eats them at night.

It's the time of year that grape growers sit back and wait, periodically checking sugar and acid levels, looking also at the visible signs of ripeness in their grapes. This morning and yesterday I tested a couple of berries for ripeness. I was a little surprised to find the Sangiovese at 19 brix, the Cabernet Sauvignon already at 20.5 brix. The berries are deeply colored. The Cabernet seeds are uniformly brown and they are crunchy. In other words, the Cabernet fruit is looking rather more ripe than I was expecting. I think it will still be two to three weeks to harvest (I try to pick at about 24.5 brix), but the grapes appear to be coming along nicely, aided by uniformly warm weather in the past week or so. The forecast is for temperatures into the low 90s for the coming week, which should keep sugar levels rising.
