A New Approach to Custom Crush
The new Sugarloaf Crush facility in Kenwood is built with all the modern amenities of an ultra-premium winery, home to prestigious brands, but not built for any one brand, winery, or winemaker.
“We’re a fully specialized custom crush facility,” says General Manager Ronald Du Preez, “We’re not a winery that’s leasing out extra space; there’s no existing brand that puts our clients in the background. We actually want our clients to be the face of Sugarloaf Crush.”
Sugarloaf Crush focuses on the ultra-premium segment of the wine business and attracts artisanal winemakers that are looking for the highest level of quality and service to craft their stellar wines. Du Preez says, “What we are able to provide here is access to all of the most technologically advanced winemaking tools, such as a state-of-the-art processing line used by some of the most prestigious wineries like Opus One, Vineyard 29, and William Selyem. A smaller producer starting in the business would not generally make such a large capital investment.”
However, having all the best equipment including Vaslin Bucher Oscyllis destemmers with vibrating berry sorting tables, an optical sorter, bladder and basket presses, peristaltic pumps, and fully jacketed, TankNet controlled fermenters, is only the first step. The second is a strong commitment to service and quality.

“Great service is knowing what your client needs even before they ask for it,” says Du Preez, “That’s the level of service we strive to provide our clients, and obviously that comes with an extremely well-trained staff.”
Sugarloaf Crush has two experienced winemakers on staff that review client work orders before cellar staff execute them. “It’s an extra level of service and quality control, so if something doesn’t look right, we can contact the client to get it right, and they can be assured that their wines are treated with the utmost care,” says Du Preez.
An innovative feature of the facility that makes the custom crush process more efficient and transparent is Innovint, a cloud-based wine and order tracking system. Du Preez explains, “The clients write their own work orders within this very simple and user-friendly system. The work order is placed in the tracking system, and as our staff completes the work in the cellar, it is logged in realtime, and notifications are pushed through to the client’s app.
“They can see that their grapes are being processed at that time, that they’re in this particular tank, they have real-time access to all their lot and analysis information.”
Another unique opportunity that Sugarloaf Crush will provide its custom crush clients is the use of a commercial kitchen and dining rooms for entertaining wine guests, distributor partners, or hosting a wine club pick up party. In contrast to many other custom crush facilities housed in industrial warehouse space, Sugarloaf occupies a traditional winery setting and overlooks the beautiful Sonoma Valley, providing the right atmosphere and experience for the consumer to match with the high-quality wines produced there.
“The option to host events here is an extension of our desire to provide the best possible service and make our clients feel that Sugarloaf is just as much their winery as it is ours,” says Du Preez.

Crush Facility Focuses on State-of-the-Art Winemaking with Premium Producers in MindIdeally situated in in Sonoma Valley—just 45 minutes from the heart of Napa Valley and a short drive from the Russian River AVA—Sugarloaf Crush (SLC) provides the latest equipment, cutting-edge technology, and a dedicated, experienced team to deliver ultra-premium winemaking for a wide range of clients in the heart of California wine country.
Founded in 2016, SLC has assembled a winning combination of precision production equipment and tailored processes designed for crafting premium wines from all varieties. In 2019, SLC opened the doors of its spectacular, 7,000-foot Hospitality Center, complete with by-appointment tasting room, thoughtfully designed private tasting suites with indoor and outdoor seating, and a superbly appointed large-event space with class-two commercial kitchen.

“We’re located in a beautiful location between two mountain ranges with vineyards out in front of the property,” explains Ronald Du Preez, Sugarloaf Crush General Manager. “We offer the absolute best in custom winemaking for discerning clients, along with great hospitality and that classic wine country feel.”
Sugarloaf Crush is outfitted with a comprehensive range of quality production equipment and facility enhancements that include:
- A cold room for immediate reception of off-loaded fruit;
- A Carlsen vibrating cluster sorting table that extracts hard raisins and MOG prior to destemming;
- An Oscillys 200 destemmer with variable roller-width settings for the near perfect berry selection
- A post-destemming sorting table from Vaslin-Bucher integrated with a WECO optical sorter
Sugarloaf Cush offers two, four, six, eight and ten-ton fermentation tank options to accommodate a full range of production needs, with the goal to support clients crafting smaller lots of high-end fruit. The facility was designed with flexibility in mind.

For tank transfer, destemmed berries can be moved via stainless-steel bin dumping or peristaltic pump. All tanks are TankNet-controlled with hot and cold glycol capabilities.
Additionally, three separate barrel rooms provide a variety of heating, cooling and humidity settings to keep barrels in perfect condition throughout the lifecycle of individual wines.
InnoVint winery management software ties the operation together and ensures everyone is on the same page, with real-time access and processing updates facilitating clear communication between crew and clients, 24/7.
Because direct sales are an essential part of every fine wine equation, SLC recently opened its onsite Hospitality Center for member clients. Featuring a by-appointment tasting room, separate indoor/outdoor suites for private tastings, and a commercial kitchen with all the gourmet bells and whistles required for next-level entertaining, the Center is a key draw for those looking for a complete custom crush service offering.

Custom Crush Winery Adds Hospitality and DTC Services for Clients“Sugarloaf Crush offers a top-of-the-line production environment, but the added hospitality services are the clincher,” says winemaker Ted Weisser, who makes his Satyre brand at Sugarloaf and is now spearheading the new Sonoma Vintners Studio at Sugarloaf Crush.
Set to open June 1, the Sonoma Vintners Studio is a 2,800-square-foot tasting lounge featuring clean, modern lines and a sought-after selection of pours from premium labels crushing at the facility. Guests will be invited to sample featured client wines in a variety of formats. “The focus will be on seated reserve tastings,” says Weisser, “but we will be open for walk-ins as well.”

The Studio is equipped with a state-of-the-art wine preservation system that allows hosts to pour a variety of artisan wines from Sugarloaf Crush’s participating clients at any time. A Sonoma Vintners Studio Wine Club will package a curated selection of wines from participating brands for a truly unique offering for visitors.
In addition to the tasting lounge, the hospitality center comes equipped with private event rooms for entertaining VIP guest, writers, and wine club members, or for meeting with distributors. The facility also includes a commercial-grade kitchen allowing for food- and wine-pairing possibilities.
“The Sonoma Vintners Studio gives the growing, premium brands at Sugarloaf a chance to expand their direct-to-consumer sales channel,” says Weisser. “We contemplated building a tasting room for Satyre, but the costs were prohibitive, so being part of the collective tasting room is a great opportunity.”
Once opened, the Studio will offer guests the full luxury winery experience on the doorstep of Santa Rosa, and will be open for regular tasting-room hours. Its location—set amidst a three-acre vineyard, landscaped lawn and terrace area—is also adjacent to the production facility, making winery tours possible, as well.

Sugarloaf Crush is currently home to 26 artisan wine brands, and those with separate tasting rooms may use the Studio as a second location or for special events or tastings. Sugarloaf Crush will manage all staffing and promotion for the Sonoma Vintners Studio.
“It’s difficult to sell consumers on the kind of premium wines made at Sugarloaf Crush without offering the full winery experience they’ve become accustomed to,” notes Weisser. “The Sonoma Vintners Studio gives our clients the opportunity to make that connection with consumers without having to build, manage, and promote their own destination.”
Sugarloaf Crush recently expanded its capacity, installing additional tanks. The winery currently has limited space to take on additional clients for 2018 crush. To learn more visit www.sugarloafcrush.com or contact General Manager Ronald Du Preez at info@slcrush.com.

For tank transfer, clients have the option to transfer destemmed berries via stainless-steel bin dumping or peristaltic pump, if a little more breakage is needed. All tanks are TankNet-controlled with hot and cold glycol capabilities, and three separate barrel rooms offer a variety of heating, cooling and humidity settings to keep your barrels in perfect condition throughout a wine’s lifecycle.

“We’re pleased that our clients are able to have this cost tracking functionality module within InnoVint as an added benefit from the software the facility uses,” Du Preez confirms. “Wines are made in the vineyards, and to allow clients to spend more time away from their desks is an added benefit for all.”

Sugarloaf Crush: Custom Crush with a Luxury Experience for Your Guests
Located in the heart of Sonoma County, our beautifully modern crush facility doubles as an upscale event venue. From intimate, private tastings to large-scale events, our hospitality wing allows our custom crush clients to interact directly with consumers and facilitates the development of a retail clientele. As we have seen over the past year, these relationships are vital—wineries have been hurting from a lack of tasting room sales, but are benefiting from the relationships made at previous visits to sell their products online. Sugarloaf clients are able to utilize our hospitality space to build and expand these relationships, developing connections that can support their business over the years.
Our spacious Grand Room offers views of Trione-Annadel State Park and provides your guests with plenty of seating for a casual gathering. Looking for something a bit smaller and more private? Book one of our suites for your next meeting or private tasting. Want to enjoy the great outdoors? Host an indoor/outdoor event and navigate your guests from our lawn into the Grand Room. Our hospitality team is here to work with you and ensure your event meets and exceeds all expectations.
