Hi everyone, and Happy New Year!
2017 has been quite the year at Aridus-- we doubled our complexity, nearly doubled our incoming tonnage, and are happy to say that we'll be bringing you a lot of new, exciting wines in the upcoming year. I have to say-- I can't wait for you all to try our 2016 reds, and am really looking forward to the eventual releases of some extended barrel-aged reds that we'll all just have to wait a while longer for.
Some of you may have heard, but for those of you that haven't-- you won't be hearing quite as much from me on this blog for a few months. I'm taking a brief leave of absence to join the Kirrihill Winery harvest team in Clare, South Australia this January through April. With any luck, I'll come back with a few new tricks up my sleeve. I'll miss everyone here, but I'll be back soon enough.
In the meantime, I hope you all had the best of holidays, and I can't wait to see you all again in the springtime!
As many of you know, just because it's Arizona doesn't mean it's not cold. Sure, we may not have snow here in the southern part of the state, but that doesn't mean we can't enjoy a big, red wine by the fire.
It may be cliched, but to me, Christmas is all about port. Back when I was at Gallo, my manager would occasionally head down to one of our more secluded facilities and bring back a case or two of the port she had made years earlier and stashed there for safekeeping. It was made of Tannat, a grape that is aptly named due to its high tannin content. All that tannin and the high alcohol from the fortification allowed it to age gracefully, tasting better and better with each year.
I've currently got one bottle left. One, unlabelled, green glass bottle tucked into the back of the wine rack. I'm not sure if I'll open it this year, or if I'll go out and buy something a little less nostalgic. As I type this out, I think I've got my answer-- I'll keep that one-of-a-kind bottle. Christmas is a special occasion, sure, but I think I'd better wait until I can be sure to savor the memories. (Beth, if you ever see this, you can always feel free to send me another one or two of that port...)
What will you all be drinking this holiday season?
Any of you who have visited me at the winery know that I'm inordinately excited by lab work. A large component of that is having good tools to work with. In this installment of my favorite tools, let me introduce you to some of the great items in the Aridus lab.
Here we have an assortment of serological pipettes. I use these frequently when I'm putting together blends-- they allow me to be extremely precise in dialing in exactly the percentages of each component that I want.
This is my -45 degree freezer. I store our malolactic cultures and a few specialty yeasts in here. The alternative is using freeze-dried cultures. I prefer these deep frozen cultures, because I find them to be more viable than freeze-dried.
Finally, this is our Oenofoss unit. All it takes is 0.6 mL of wine to tell me everything I want to know about it from a chemical standpoint-- alcohol percentage, residual sugar, titratable acidity... It's a very handy piece of equipment if you're interested in tracking as much analytical data as possible about your wines!
Happy Hanukkah, everyone! In honor of the holiday, which starts tomorrow, we thought we'd take a little time to talk about kosher wine options. Unfortunately, Aridus does not offer a kosher wine at this time, but we're more than happy to point you in the direction of some elegant options.
The wine that most people think of here in the US is, of course, Manischewitz.
It's Concord-based, which means that it's made from non-vinifera grapes. Vinifera are the species that produce the wines we're most familiar with-- your Cabernets, Chardonnays, Syrahs, and so on. As a result of being a different species, a lot of the aromatics are different. That Concord aroma that carries through to the wine is what is known in the wine industry as "foxy." The compound is methyl anthranilate, and there are a lot of claims as to where the descriptor "foxy" came from, but one story goes that to the British, wines made from American grapes smelled like fox dens. In any case, it's not a bad thing, just a different thing than what most of us are used to from a table wine. All the products in the Manischewitz line have at least some measure of residual sugar, so if you're looking for a dry wine, you might want to look further, but if you want a bit of sugar and want to try something different, give Manischewitz a shot!
One excellent source of fine kosher wines is none other than the country of Israel. Wine grapes have been growing in the area since probably around 5000 BC, but modern kosher wine production really began in the 1880s. The producers in Israel are truly producing wines that are world class that just happen to be kosher at the same time. A huge selection can be found at the online retailer kosherwine.com. Look for red wines from Israel in particular, such as Cabernet Sauvignon-based wines, Syrahs, Malbecs, and one of our favorites here in Arizona... Petite Sirah.
If reds from hot climes aren't your cup of tea, never fear. There are kosher wineries throughout the world. Oregon's Evan's Vineyard produces a pinot noir and a meritage blend from Washington, and the same owners produce the Goose Bay label out of New Zealand to quench your thirst for Sauvignon Blanc. If you must have Napa, look for something from Covenant. They have Cabernet, of course, but also Sauvignon Blanc and Chardonnay.
See what you can find, and be sure to let us know if you have any particularly fantastic kosher wine this Hanukkah!
An increasing portion of wines by the glass at restaurants are packaged in kegs. These are inert stainless steel, and come in a variety of sizes-- from 2.5 to 30 gallons. Most people are familiar with beers in kegs, and for the same reasons that they are good containers for beer, they are good for wine. What's more, they can minimize the cost of a glass of wine, because the restaurant is no longer passin galong the cost of the packaging of a wine in glass, nor the possibility that the wine will go bad before reaching a consumer. Effectively, this means a high value wine at a lower price point. While consumers may never directly purchase a keg of wine, it makes a lot of sense for restauranteurs.
Winemakers who currently use kegs for a portion of their production often note the high quality of the wines, despite the age of a keg. At a recent industry gathering, one cited an example of a half-filled keg that was returned to the winery a year after being tapped. “The wine was in perfect condition,” he said.
Since the expense of starting up a kegging program can be pretty steep, winemakers in more winery-dense areas now have the option to work with commercial wine keggin services to oversee the packaging, storage, and delivery of kegs. A third party kegging operation saves wineries from needing to purchase their own kegs, in addition to the cleaning, sanitizing, and packaging, which many wineries aren’t set up to do easily.
I have great hopes for the future of wine kegging in Arizona. As far as I know, only one winery is currently in the keg business, but I think it makes a lot of sense if you have the sort of volume to make it work, and if you are invested in bringing in customers through their experiences with your wine in a restaurant setting. Who knows? Maybe in a few years, you'll be able to enjoy a glass of Tank 12 right from the tap.
Have you ever had someone tell you that wine isn't vegetarian? Why wouldn't a wine be vegetarian if it's pretty much just grapes?
Well, there are a few fining agents that are derived from animal products. In winemaking, we typically use fining agents to bind with and precipitate out certain particulate, like proteins or astringent tannins. While they don't remain in the wine (they usually drop out or are filtered out), the most stringent of vegetarians may take issue with their use in the first place. In this post, we'll discuss animal-derived fining agents, but be on the lookout for one in which we discuss non-organic fining agents.
These days, egg proteins are added mostly as soluble albumin, but in the past, egg whites were used directly. The purpose of using egg whites is to bind harsh tannins. The egg proteins promote the formation of protein/tannin complexes, which are quite large and drop out of solution naturally.
Similarly to albumin, gelatin is another protein that is used to bind up harsh tannins. When using gelatin, it's often necessary to use protein-binding agent afterward to ensure that all the gelatin is removed from the wine, since any residual can cause a haze. Gelatin is highly reactive and should be used early on if at all, since it can remove color along with tannin.
Perhaps the oddest ingredient of the bunch, isinglass is made from the swim bladders of sturgeon. It is also a protein, and tends to be a gentler fining treatment than gelatin or eggs.
Casein is a milk protein that is commonly used for removing oxidized particles in wine, or the compounds that can cause certain white wines to turn a pinkish color in bottle. It can be used to reduce bitterness, as well, but unlike the other animal-derived fining agents, it is not primarily used for removal of astringent tannnins.
At Aridus, we try not to use these particular fining agents. In 2016 we used a slight amount of gelatin to fine our Malvasia and Muscat juice, as it was slightly more astringent than we would have liked prior to fermentation. We followed up the gelatin addition with silica to remove any remaining gelatin. We racked these wines multiple times prior to bottling, and filtered them as well, so I wouldn't expect any gelatin to have made its way into the bottle.
While it's good to have these on hand for the few times they may be the best choice for wine quality, in general, we aim to utilize non-organic fining agents, like bentonite or specialized tannins. More on those to come!
Like every wine obsessive, there are certain wines I like to pull out for special occasions, and since it's almost my birthday, I thought I'd let you in on what I'll be cheers-ing with this year: Pinot Noir.
I know that now that I'm in Arizona, I should perhaps adapt. and reach for a bottle of our secret, small batch, sparkling Malvasia Bianca... maybe next year. Don't get me wrong-- I love our sparkling Malv, but I'm really in the mood for something simultaneously earthy and ethereal, delicate and powerful. I'm in the mood for a Pinot.
Pinot is probably one of the most ancient grape varieties still in cultivation today, clocking in at something like 2,000 years of age. We can determine this based on the high number of mutations within its genome, and the huge number of parent-offspring relationships it has with other varieties. It has crossed with Gouais Blanc multiple times to create such varieties as Chardonnay, Gamay, and is the grandparent of Teroldego, and even the great-grandparent of Syrah. In addition, it is either the grandparent, or the sibling of Chenin Blanc and Sauvignon Blanc-- which is unknown due to a missing genetic link between it and the grape Savagnin that would tell us which was the parent of which.
Pinot grows across the globe, but tends to do best in cooler climates, thus it can be found from its homeland in Northern France's Burgundy, to Russia, to Tasmania, to Patagonia, to Oregon, to the Verde Valley. It has a tendency to bud out early, and can ripen very quickly in hot climates. Its skin is very thin, making is susceptible to various fungal rots, easy to split if the vine takes up too much water, and an easy target for viruses. In short, Pinot is a pain to grow in most climates, and in those where it's not, it tends to taste boring. But when it tastes great, in my opinion, nothing can beat it. Frash berries, cherry cola, roses, black pepper, porcini mushrooms, cedar... the list goes on and on. Pinot is such a delight to sniff and swish.
Luckily, you don't have to wait long for another Pinot bottling from Aridus. This past year we worked with some folks up in Oregon's Willamette Valley to bring in a little Pinot, and we hope to have it bottled in the next few months for release sometime in 2018.
And without further ado, this is what I'll be drinking for my birthday:
Bubbly! Because for all it's beautiful still expressions, Pinot Noir makes a fantastic Champagne. And nothing says celebration like bubbles. I'll save the Burgundy for the Thanksgiving feast.
Ever since Constellation introduced Black Box, wines of all quality levels and price segments have been gaining traction with consumers, retailers, and producers alike. Let's break them down and understand why!
Boxes as a wine package consist of a polyethylene bag with a spout inside a cardboard box. They are meant for wines that should be drunk relatively quickly, generally within three months of packaging. This is because the plastic is semi-permeable, and can break down to contribute off-flavors to the wine.
The benefit is that the bag is flexible and deflates as wine is dispensed, which means that oxygen doesn't enter through the spout. Winemakers need to think about volume of headspace in the bag, since it is never completely filled, and what type of gas is in that headspace. It's usually just whatever is in the environment. Even though the bags can be purged with nitrogen the same way a bottle can, we're much more likely to damage the bag in the process. Additionally,to make the switch to packaging in boxes, wineries need to purchase a new bottling line or contract out services with a winery that already has one.
One nice aspect of a box for marketers and retailers is that it can be interestingly shaped, and there's a lot of space to make the product look interesting, fun, sophisticated, or attention-grabbing in some other way.
One of the blessings of boxed wine can be its downfall— its easy packability. Because wines packaged in box are square or rectangular, there’s less dead space on a pallet. Without glass, though, the wine lacks structural support, so pallets cannot be stacked more than two high. Damage to the boxes during transit can be a huge deterrent to consumers, resulting in unsalable product. After all, damage to the box may or may not represent damage to the wine inside.
There's nothing inherently wrong about drinking boxed wine. They can sometimes represent incredible values. I recommend the Jack Tone Red Blend if you can find it, and in a pinch, Vin Vault will do the trick. Why not give one a try, even if it's not an Aridus wine? You might surprise yourself and find your everyday drinking wine!
Happy Halloween, everyone! In honor of one of my favorite holidays, I thought it only appropriate that we discuss one of the cheapest and most effective wine ingredients available: GHOSTS.
Okay, they don't look particularly creepy, and what are they? Ghosts, also known as yeast hulls, are the cell walls of dead yeast. And it turns out, that they contain a lot of helpful compounds that can keep your fermentation or even your malolactic conversion from stalling out.
During fermentation, yeast throw off a lot of byproducts. Mostly alcohol, CO2, and heat, but also plenty of other compounds, like the aromatics mentioned earlier this year. Some of these byproducts are toxic to yeast-- alcohol for one, but also octanoic and decanoic acids. Ghosts can help fermentation by adsorbing these acids-- essentially pulling them out of the wine, and making the environment a little more friendly to the yeast that are working there. They also provide some of the nececssary components for living yeast to build healthy cell walls-- sterols and long-chain unsaturated fatty acids. Even after alcoholic fermentation is complete, their presence helps malolactic conversion for a lot of these same reasons-- octanoic and decanoic acids are also toxic to malo bacteria, so less concentration helps the bacteria do their jobs.
There's evidence that ghosts may also help prevent certain white wines, such as Pinot Grigio and Sauvignon Blanc from turning slightly pink in bottle, and that the addition of ghosts during fermentation can help promote tartrate stability. They can even help wines that have high levels of cork taint [a compound called TCA]. Adding ghosts can help remove some of this compound from the wine.
So there you have it-- one little ingredient with a myriad of uses. I hope the ghosts that surround you today are just as helpful!
Hi everyone! Now that we've finished pressing, and we're putting the wines to bed for the season, it seemed like a great opportunity to talk a bit about the tools that are most helpful to us when working with barrels.
First up is the stirring wand, pictured below. It's a curved metal rod with a rotating metal oval at one end and a handle at the other. It's a great tool for doing ingredient additions to barrel, and lees stirring. You simply pull the bung out of the barrel, and slip the oval end in. You use the handle to rotate the wand around in the barrel and you can pretty effectively mix up all the contents.
What do you do if you're fermenting in a barrel, or if a wine is still going through malolactic conversion, and you want to keep the outside world out? Use a fermentation bung! We have two types on hand here-- one with a flexible silicone cap that fits down the middle of a 5-holed bung (on the left below), and one that has just one hole with a smaller silicone plug that fits through the hole and has a foot holding it in place (on the right below). These move just enough to allow the gas produced during fermentation to escape, and come back into place to prevent anything from getting in the barrel. I tend to prefer the option on the left because it's a little bit more flexible and in my experience has less chance of blowing out.
Lastly, the workhorse of the barrel room, we've got the barrel rinser. Are we prepping a barrel that's been empty for a few months to receive wine? Are we cleaning out a barrel after a racking? Are we doing just about anything with a barrel? Yes? Then we're going to rinse it! This nifty little number easily slides into the downward facing bunghole of a barrel, and allows us to give the barrel a thorough spraying of water or ozonated water. In the photo below, you can see on the left where the rinser connects to the water supply, a valve to open or close the water supply, a small foot below to hold the rinser in place, and on the right the spinning head. It works by pressure, so it uses the pressure of the water itself to turn. Simple, elegant, and effective.
These are just a few of the tools that we use when working with barrels, but they're some of my favorites. Check back in periodically, and I'll show off some more of the tools of the trade.
