Preparing for the Harvest

The harvest is here, or at least it’s close. Our Viognier grapes should be ready to harvest next week (I had thought a week ago we’d would have harvested yesterday), and the Merlot and Cab Franc won’t be far behind.

My Viognier at the end of August, partially obscured by bird netting, is looking fabulous

So, I’ve been scrambling over the past month or so to get ready. With a few notable exceptions involving John Updike, virtually all of my reading lately has involved winemaking. And the free time that I haven’t devoted to reading about wine chemistry or winemaking techniques have been spent assembling the equipment and supplies I need to make wine.

And it seems that I need a lot. I think the average cost of a bottle of wine from this vintage will approach the price of a bottle of Chateau d’Yquem. There’s a part of me that wonders if it wouldn’t have been smarter to have spent all that money buying someone else’s wine. But really, where’s the fun in that?

The learning curve has been pretty steep, and I’ve made a bunch of mistakes — even though I have yet to harvest my first grape. After learning all about free and bound SO2, pH, fining and a hundred other things, I realized I was all but clueless on a number of practical matters, such as which yeast to use for each grape variety. For hobbyists like me who are buying yeast in quantities of 50 to 80 grams at a time, the options are more limited than they are for commercial wineries that are turning out tens of thousands of cases of wine. But that’s a relative thing. There are still 40 or 50 different yeasts available in small quantities from companies like More Wine and Midwest Supplies.

I still remember a class at King Family Vineyards where winemaker Matthieu Finot invited us to taste wines from three different barrels. They were all distinctly different, and I was truly surprised when Matthieu told us that they were all made from the same grape variety from the same vineyard bloc and vintage, and that the only difference was the strain of yeast he had used. Clearly, yeast matters!

The Vineyard Goddess and I went to a lot of trouble to pick what we thought were exactly the right clones for each of the grapes we planted – and some of the clones we wanted were not easy to get – and the right root stock as well. So, it only made sense that we should go to the same lengths to get the right yeast. After lots of reading and lots of anxiety, I selected Rhone 4600 for my Viognier (and I think also for the Petit Manseng), Bordeaux Red (BDX) for the Petit Verdot, MT for the Merlot, and BM4x4 for the Cab Franc. And then, on reflection, I ordered something called BA 11 for the Viognier, even though I already had the Rhome 4600. Here’s the writeup on More Wine‘s web site for the BA 11:

BA11 was selected in 1997 near Estacao Vitivinicola de Barraida in Portugal. It has excellent fermentation kinetics, even at low temperatures. It promotes clean, aromatic, estery characteristics during fermentation. BA11 intensifies mouthfeel and augments lingering flavors in both still and sparkling white wines. BA11 encourages the fresh fruit aromas of orange blossom, pineapple and apricot. In relatively neutral white varieties BA11 brings out tropical fruit, cream, vanilla and spice. With fruit from hot climates, BA11 can really help to “flesh out” a wine by its’ volume and mouthfeel enhancement. This strain is good by itself, as well as being a great structural component to a blend. Best results from 50 to 77 degrees F, and alcohol tolerant to 16%.

Sounds pretty good, right? Well, for now. I’ll probably wait until I’m running the crusher before I settle on the yeast. Oh, and I still haven’t decided which yeast strain to use for the Petit Manseng.  Maybe the Rhone 4600? Well, I was feeling pretty good about the future of my wine when I realized I hadn’t yet ordered malolactic bacteria, the stuff that converts tart malic acid to softer lactic acid, generally just in red wine. Not to worry. I went back to the More Wine site, did some research, and ordered enough ML bacteria to soften an ocean of malic acid. Well, maybe not an ocean.  But at least the dozens or so (yes, I am an optimist) gallons of red wine I will be producing this year. It turns out that ML bacteria packages, once opened, can’t be saved. So for each of the three reds I’ll be making, I had to order separate batches of ML bacteria, at about $33 a pop.

I’ve ordered a half-dozen glass carboys and an array of other equipment.

And that’s barely scratching the surface of the purchases I’ve made in the past few months. I’ve accumulated lots of lab equipment, including an instrument that measures pH, sulfur dioxide, and titratable acidity. I bought a high-precision scale, an assortment of flasks, beakers, air-locks and stoppers, and four new plastic fermenters: two that can hold ten gallons of must and two that can hold 20 gallons. I already have a number of 7.9 and 6 gallon fermenters, so I’m feeling ready for a harvest of almost any size. And I’m really praying that I can actually fill at least one of the 20 gallon tanks.

There are also a few additives that are necessary, and some that are not, strictly speaking, necessary, but are helpful enough that I’ll probably try them out. In the can’t-do-without category are yeast foods. There are a few different ones available, both for mixing with the yeast when it’s being prepared for inoculation and for helping the fermentation along in the days that follow, but I settled on Go Ferm and Fermaid K.

Other additives include Tartaric Acid for making adjustments in the acidity of the must, Albumex Bentonite and other fining agents, and oak cubes, which substitute for the oak barrels that I don’t have. I could go on about additives, but I’ll stop here for now. In the next post, I’ll cover the big items, such as the crusher-destemmer and the construction of my garage “barrel room.” For now, though, I’ll close with a short list of the books and online publications I’ve found most useful.

First, I can’t say enough about the folks at MoreWine. In addition to all the stuff they’ll sell you — and they have a well-organized site that includes quality equipment and ingredients at reasonable prices with lots of information — they have a series of free booklets and guides that I would probably have been willing to pay for. The guides to red and white winemaking run nearly 100 pages each, and are full of practical information. In addition, they have guides to SO2, the use of inert gas, bench trials and a number of other subjects. After reading a bunch of other books, I found these manuals provided the down-to-earth practical information I needed to go from the vineyard to the bottle.

David Bird’s Understanding Wine Technology was also quite useful. It provides a good overview of almost every imaginable topic in winemaking, and gets into considerable detail.  If you’re wondering how yeast works its magic or what carbonic maceration does, this is a great book.  It isn’t the practical, down-to-earth kind of manual that MoreWinemaking provides, but it includes a wealth of information and it’s a joy to read.

David Pambianchi’s Techniques in Home Winemaking is probably the most detailed and thorough book on subjects of interest to home winemakers that I have ever encountered.  This is a book that I have perused, rather than read, but I’ve used it to get loads of technical details on topics of interest.  I’m thinking it’s a must-have for any home winemaker.

One of my favorite books on viticulture and winemaking is Authentic Wine by Jamie Goode and Sam Harrop.  Split roughly in half between the two subjects, this book  helped me understand what kind of winemaker I wanted to be.  It covers lots of important subjects, like Brettanoymyces and free vs. bound SO2, but it also gets into some of the philosophical issues, like how much intervention in the cellar is okay.

The very first book I read, some four years ago, was Jim Law’s The Backyard Vintner.  It doesn’t go into great depth on any subject, but it provides a more than adequate overview of all the important topics in viticulture and winemaking in very accessible prose.  Jim Law owns Linden Vineyards, one of Virginia’s great wineries, and the articles on the Linden web site are also well worth reading.  (And while you’re at it, check out Jim’s articles in the last two issues of Grape Press, the publication of the Virginia Vineyard Association, as well as an article in the next issue, which should be out by the end of September.)

And finally, the second book I read, just after Jim’s book, was Jeff Cox’s, From Vines to Wines.  This is an excellent guide that covers everything from planting your vines to bottling the wine. If you’re not sure how to prune second year vines or how to rehydrate yeast, this book has everything you need.

There are many more books, I’m sure – I actually have a couple sitting on my shelf that I haven’t yet begun to read – on the subject of winemaking, but these should be enough to get anyone started.  I wouldn’t say they’re a substitute for classes or hands-on experience, but they’re certainly an important supplement.  God knows, I’ve found them invaluable.

Tempranillo, Part II: The Hydrometer Never Lies

I was pretty excited last Monday when I began making six gallons of Tempranillo wine.  I thought I had been pretty clever in the way I had gotten the temperature just right before pitching the yeast, and I was pretty confident that things would go well.

The must on Day One, floating thermometer barely visible..

The must on Day One, floating thermometer barely visible..

And 24 hours after inoculating the unfermented must with yeast, I was pretty sure fermentation was well underway. The airlock was beginning to accumulate carbon dioxide, or CO2, bubbles and there was a fragrance in the air that I have always associated with fermentation. Also, there was a loud hissing sound inside the primary fermenter said there was something alive and growing inside. Yeast is a truly amazing microorganism.

Forty-eight hours in, I was beginning to worry. The airlock wasn’t bubbling up and down in  the vigorous way I had expected, and I wondered if the fermentation had become stuck. Or worse, if it had actually been stillborn, and I had only been deluding myself the day before. I punched down the grape skins for a couple of minutes (the grape skins are pushed to the top of the fermentation vessel by the CO2 released during fermentation, and they must be “punched down” daily to ensure proper contact with the must – more on this in a later post) and then checked the temperature.

The results were a bit scary – almost 90 degrees. Apparently the heater I was using was a blunter tool than I had thought. That seemed a bit unjust. The last time I made wine, fermentation took forever, and was briefly stuck because I had let the house get too cold. Now, I had apparently gone too far in the other direction.

On  Thursday, I was feeling even worse about the fermentation. I had shut down the heater, and the temperature had dropped to the low eighties.

twenty-four hours later, fermentation appeared to be clearly underway.

twenty-four hours later, fermentation appeared to be clearly underway.

Better for fermentation, but probably still a bit too hot to re-inoculate. I knew I could get the temperature down, but I wasn’t really sure how to go about reinoculating.

I had packages of two different kinds of yeast: RC212, which was the particular kind of yeast that came with the kit, and EC1118, a champagne yeast that is also supposed to be good for restarting stuck fermentations. I wasn’t sure which to use, whether I should rehydrate the yeast with some of the juice before pitching it, or whether I should get the temperature down first. So, I called the company’s technical support line.

I was using a Winexpert kit, and I can’t begin to say enough about their customer support. I got a real person on the phone in a couple of minutes, and she was terrific. Here’s how the conversation went (picking up after I explained the problem):

She: What was the specific gravity when you pitched the yeast?

Me: 1.082

She: What is it now?

Me: I haven’t checked, but since it doesn’t seem to be fermenting, I assume it’s still right around 1.08.

She: You need to check. Give me your number, and I’ll call you back in ten minutes while you take a reading.

Me: OK.

After about ten minutes, she called back.

Me: I just finished sanitizing the hydrometer and wine thief and I’m just filling the tube (for the hydrometer).

Here's the hydrometer, still bobbing up and down a bit in the test tube.

Here’s the hydrometer, still bobbing up and down in the test tube.

She: OK.

Me: Uh. . . Can this possibly be right? It looks like it’s 1.02.

She: You got it! It’s working.

Me: Uhhhh . . . yes, it is.  (but thinking, yes, I am an idiot. . .)

What I learned from her was to rely on the hydrometer, not my visual checks. She was good enough to stay on the phone with me for another five minutes to talk about winemaking and to answer a few more questions about the kit. Honestly, it was one of the best customer support experiences I’ve ever had.

So, I let the wine continue fermenting. Twenty four hours later, the specific gravity was down to 1.011, and the night after that, it was just a hair over 1.000, maybe 1.001. Sunday morning, I’ll check again, and I think it will be time to rack it into a carboy for the secondary fermentation.

Meanwhile, I’m planning to start making a new batch of wine in a week or two, this time Winexpert’s Lodi Ranch 11 Cabernet Sauvignon.  And I’ll be relying less on visual observations and more on things I can measure, like temperature, pH, and specific gravity.

After all, your eyes may deceive you, but the hydrometer never lies.

Making Tempranillo, Part I

So much of what I’ve written on Project Sunlight has to do with the vineyard – planting vines and tending them until they’re ready for that first harvest. Well, okay, we’re actually a long ways from that first harvest, so in fact most of what I’ve written has to do with that first year in the vineyard, from preparing the ground to planting and caring for the vines over the course of that year. Someday soon, I hope to write the next chapter, the one that has to do with turning simple grapes into something noble. But we have at least another two years before we take that step and make wine from our grapes.

And yet, I want to make wine – now.  So, what to do? I am very hopeful that next fall I’ll be able to buy fresh fruit from somebody else’s vineyard, and make wine from those grapes. But that’s a long ways away, and I’m feeling a need to get some experience with the whole process of fermentation before I start playing with freshly harvested grapes.  It’s also possible I’ll be able to buy some grapes shipped in from Chile in the next month or so (the southern hemisphere runs opposite to our world – our fall is their spring, and their spring is our fall), but I’m not sure about that.

Here's the 7.9 gallon fermentation bucket next to the box containing the juice and grape skins

Here’s the 7.9 gallon fermentation bucket next to the box containing the juice and grape skins

Wine kits, though, offer a world of possibilities – literally.  You can get kits that contains juice and crushed grapes from Argentina’s Mendoza region or South Africa’s Western Cape. You can buy Chilean Cabernet Sauvignon or Australian Shiraz or Oregon Pinot Noir, for that matter, and make those wines at home whenever you want.

Years ago, I turned my nose up at the idea of making wine from a kit.  But from what I’ve read over the past few years, kits have gotten better and better. Two years ago, after receiving a starter set with all the equipment from my daughter as a Christmas gift, I tried my hand at one. I made so many mistakes that I should have been grateful to have ended up with decent vinegar.  But I worked hard at it, and when I was finished I decided that the very least I could say about it is that it was honest to God wine.

I wondered if that would be the most I would ever be able to say about it as well, and I suppose the answer is somewhere in the middle. It wasn’t great wine, but my kids liked it well enough to ask me to bring a couple of bottles with me when I traveled out to visit (in California, no less), so it at least found an audience. And every time I open a bottle, I tell myself, “Hey – this ain’t so bad.”  And yes, I know – that’s a pretty low hurdle.

In any event, I decided to try my hand at it again. This time, I’m making a Spanish Tempranillo, one of my favorite varietals. The kit was made by Winexpert, and it came with a bladder of juice, a smaller bladder of crushed grapes, and of course all of the yeast, fining agents and the like that one needs to turn the juice into wine.

Natural Wine, part I: Alice Feiring’s “Naked Wine”

Alice Feiring: Naked Wine

One of the most arresting moments in Alice Feiring’s book on natural wine is occasioned by a question she posed to Jacque Neauport, one of the movement’s pioneers, on what motivated him to make wine without sulfur.  He is momentarily speechless, then nearly convulsed with laughter.

“Because we were drunkards!” he finally responds, explaining that they hoped that wine without sulfur would allow them to drink heavily and avoid hangovers.  Ms. Feiring is clearly shocked.  “I had come to the oracle for answers, and all he had for me was a punch line,” she writes.

There’s something disarming about these passages, although I suspect that readers who have been put off by her writing style and dogmatic approach to natural wine will take some pleasure in her discomfort.  My reaction was different.  I’m not sure I would have had the courage or confidence to retell a story like this, so it made me like her, as well as her book, a good deal more than I had up to that point.

Early on, I wondered if I would be able to recommend Naked Wine, or for that matter, even finish it.  Her book is written in the style of a blog, and it is infused with her personality.  If you happen to like that personality, you will probably like the book.  If you find her style, as a friend of mine did, “annoying,” then you will find much of the book insufferable.

At the end, I’m somewhere in the middle.  The book is definitely not for everyone, but for those interested in making an initial foray into the world of natural wine, it’s a pretty good introduction. Continue Reading–>

Planting the Vineyard, Part I

With the trellis posts finally in the ground, we were finally ready to plant.  And not a moment too soon.

When we arrived in Afton on Friday evening, March 30, we had 50 dormant vines waiting for us: 25 Petit Manseng from Vintage Nurseries in Wasco, California, and 25 Viognier from Sunridge Nurseries, Bakersfield, California.  The largest number of vines we had ever planted before was seven, and we weren’t sure how long it would take to get

Here's the Petit Manseng vines still soaking in water just before planting

these vines in the ground, or even if we’d be able to get it done by the end of the weekend.  But we had another 100 vines set to arrive the following weekend, which meant we didn’t have much of a choice.  We decided to plant the Petit Manseng first, and prepared them by putting them in a bucket of water to soak overnight.

In the morning, we inspected the vines to see if they looked healthy.  This was kind of like the time in high school when my car wouldn’t start as I was taking my date home.  I opened the hood, looked inside as though I knew what I was doing, and just prayed it would start when I got back in the car.  It did start up, Continue Reading–>

Welcome to Project Sunlight

Welcome to Project Sunlight, a blog about wine and my attempt to become a winemaker.

You may have noticed that the banner on my blog suggests that I will learn and chronicle all there is to know about this subject over the next year. That’s not exactly correct, although it’s a useful shorthand that does happen to fit within the banner. The correct part is that I plan to learn as much as I can about winemaking over the coming 12 months and discuss what I’ve learned on this blog. The incorrect part has to do with the timeframe. Continue Reading–>
