Las Jaras

Las Jaras is a joint project between Eric Wareheim (of Master of None and the Tim and Eric Awesome ShowGreat Job! fame) and his friend Joel Burt, who has been making wine in Napa and Sonoma since the early 2000’s. The project started as a result of Eric and Joel’s shared passion for authentic wines. In their own words:

“At Las Jaras, our goal is to make delicious wine that has tons of energy and balance. We want them to be vibrant, delicate, and supple all at the same time while also being food friendly and easy for anyone to enjoy. Our wines are designed to reflect the unique terroir of the vineyards using minimal intervention so you can taste their natural, rhythmic expression. If you are not used to drinking wines made this way, the experience can be a revelation.

Our lighter wines can elevate your daily experiences. Bring the elegant bubbles of our Sparkling Wine to your best friends engagement party. Nestle the Rosé into your backpack for a trip to the park to watch an epic sunset. Pair the chilled Glou Glou with a margherita pizza to make takeout tastier. 

Our medium bodied reds pair with deep savory meals and create thought provoking moments. A holiday dinner includes a conversation about Carignan. The Cabernet Sauvignon is brought to your favorite restaurant to share a taste with your server. “Does this remind you of 70’s Napa?” And our Sweet Berry Wine demands explanation, inspires stories, and creates joy. For your Wine!”

Sparkling Carignan — Back to the top

“This is the second vintage of our sparkling wine made using this method. We wanted to explore making a full pressure wine with sufficiently ripe grapes that would not require long aging, multi-vintage blending, or dosage. We are unsure what to call this method of winemaking. It is kind of like a cross between the traditional method (picked early, dual fermentation, high pressure, often sweetened) and a pétillant naturel (picked ripe, single fermentation, low pressure, sometimes finishes sweet.) You can think of our method as a high pressure, naturally balanced wine without sugar added.”

Vineyard: 100% old vine Carignan from McNabb Ranch Vineyard situated between Hopland and Ukiah in Mendocino County. These grapes are the same ones used to make the base wine for our 2017 still Rosé. We split the sparkling portion off at mid-ferment.

Winemaking: The hand-picked grapes were whole cluster pressed to a tall skinny stainless steel tank. After racking the clear juice at 150 NTU, we kept the juice cold in tank and circulated it on the lees weekly for six weeks using the “stabulation” technique. When the wine started to tick, we set the cooling on the tank to 68°F and let the wine ferment naturally. When the wine reached about 3 brix we chilled the tank to arrest fermentation. We let the tank sit cold for several weeks to clarify and cold stabilize. When it was time to bottle, we racked the wine, added a small amount of organic yeast extract (food for the yeast) and a yeast culture that was built up from an isolate on a slant. The wine was stored sur latte (on its side) for six months and sur pointe (upside down) for two months before it was disgorged. We simply topped the bottles and did not add any sugar or sulfur.

Rosé — Back to the top

“General thoughts on Rosé… Rosé should be fresh and vibrant, delicious and gulpable. You can’t just simply pick grapes earlier for rosé, because the wine will be out of balance. The grapes need to achieve appropriate ripeness for a great rosé. We handpick the grapes early in the morning and get them to the winery as early as possible. We want to minimize skin contact and phenolic extraction. Usually, we want to avoid malo-lactic fermentation, but this year the malo-lactic fermentation finished during primary fermentation.”

Vineyard: 100% Carignan sourced from McNabb Ranch Vineyard, which is between Hopland and Ukiah in Mendocino. These old vines were planted in the early 1950’s. The vineyard is dry farmed. The soils are Cole loam and the vineyard is covered with turkey mullein. Carignan in the area is quite prone to powdery mildew, but the grower does a great job of managing it with sulfur dust and canopy management. These vines stand at about 8 feet tall, which really allows air and light to penetrate the canopy.

Winemaking: We picked the vineyard at 20.1 brix. The handpicked grapes were whole cluster pressed in a horizontal bladder press. The free-run juice and press up to 1.6 bar was taken to tank. There was no skin contact and minimal tumbles. The juice was cold settled and racked. The juice was kept on its fine lees and stirred weekly for 6 weeks to allow the big fruity flavors to subside and more floral ones to take their place. Once the wine started to tick off, we let it ferment with native yeast. Fermentation was at 60-65F. Once fermentation finished, we kept it on its gross lees and stirred (inertly) twice a month until just before bottling. The wine was fined prior to bottling with a small amount of bentonite to heat stabilize and pack down the lees. The wine was not cold stabilized.

Chloe Carignan — Back to the top

“General thoughts on Carignan: Carignan is such an intriguing variety for us. At its best it is juicy, brambly and spicy. At its worst it is tannic, sour, and tastes like cabbage. It can also be quite difficult to grow. They are generally vigorous old vines that stand 7-8 feet tall. The vine is extremely prone to powdery mildew infection, so it needs meticulous canopy management to avoid disaster. Site selection is important for this variety to perform. It needs to be on benchland, with properly draining sandy loam soils and a hot climate. The light soils help regulate the vine’s vigor and the heat helps respire acid, which can be absolutely searing on this variety.

Vineyards: 100% Carignan sourced from Gary Venturi’s vineyard in the Calpella area of Mendocino County near Ukiah on the benchlands to the west of the valley. Gary and his dog, Kelsey, tend the vines. They were planted in the mid-1960’s. The vineyard is dry farmed and sustainable. The soils are Yokayo series sandy loam. When dry it is like walking on the moon. The vineyard is super clean due to Gary’s fastidious suckering and canopy management. I think it’s also due to being on the right soil for Carignan. It only needs 1-2 sulfur dustings per season.

Winemaking: We hand-picked the vineyard at 23 brix. Gary has a few vines of Golden Chasellas growing on the property so we asked to have them added to the pick. When the grapes arrived at the winery, we tipped half of the bins into the open top fermentor as whole clusters and we destemmed the rest. We added no SO2 and kept the tank jacket set a 72ºF. We were very gentle when handling this variety because it can be really tannic especially with such concentrated fruit. We used only light punchdowns, just wetting the cap. We did one punchdown per day until the native fermentation kicked off and then increased the punchdowns to two per day. After the mid-point of fermentation, we backed off to one or no punchdowns. Once the tank was dry, we drained it overnight and pressed the skins and intact clusters in the morning using a tank press. We aged the free drain and the press separately in 228 liter Burgundian barrels; none of them were new. We aged the wine in a cool room where they underwent native malo-lactic fermentation. We racked the barrels about a month before bottling and then back to clean barrels. We racked again a few days before bottling and the wine was limpid. This is our method of creating wines that are clean without being filtered. We bottled unfiltered and unfined.

Glou Glou Red — Back to the top

“Our mission with the 2018 Glou Glou was to create the perfect warm-weather red: something fresh, chuggable, and light that tastes like sparkles and bright, summer fruit. Serve this slightly chilled, and you will be the hero of your next backyard barbecue—this is the most refreshing red wine ever, and the perfect antidote to long summer days and the heat of the grill. Glou Glou has intense berry notes that perfectly complement the char of a burger or perfectly cooked pizza crust, and enough acid to stand up to your favorite tomato sauce. Pizza, burgers, and wine are, after all, the Las Jaras holy trinity. (If more people subscribed to our religion, would there be world peace?) Most of the grapes in Glou Glou underwent carbonic maceration, the classic fermentation method of the Beaujolais, which means that fermentation happened inside of berries themselves, causing them to explode in happy, boozy ecstasy. That’s how you’ll feel when you drink this wine—it dances in your mouth.”

Winemaking Details: Whereas last year’s Glou Glou was 100 percent Charbono, this year we used several different varieties from a handful of old vine vineyards in Mendocino and Solano Counties. We picked the grapes early (between 20 and 21 brix), to keep the alcohol level below 12 percent and some nice fresh acidity. We vinified each of the individual lots separately. Most underwent carbonic maceration, a gentle process that helps to keep earlyharvest wines from becoming too tannic. After 7 to 12 days, depending on the lot, we pressed the juice off its skins where they fermented natively in tank. Then, half of the lots were aged in barrels, half in tank, to keep the wine bright and fresh. We bottled without any fining or filtration, so store Glou Glou in a cool place. We do not de-gas our wines, so it may benefit from a quick decant to blow off CO2, especially when young.
