In a statement on LinkedIn yesterday (24 June), the California-based business, formerly named Mercenary Canning Solutions, announced the launch of Mercenary Premier and the purchase of the facility in Edna Valley.

Treasury Wine Estates also confirmed to Just Drinks that the site has been sold. The group said it could not speak further around “specific property transactions or assets that may or may not be on the market”.

“The facility will serve as the company’s anchor location for full custom vinification services, expanding its capabilities beyond mobile packaging and into comprehensive winery production,” Mercenary Premier said

The co-packer aims “to build California’s leading destination for custom vinification and end-to-end winemaking services,” the statement added.

According to the business, the Baileyana Winery site has “some of the most advanced winemaking technology available in the region”.

It also said “the newest laboratory equipment provides reliable, timely in-house analysis to support precision winemaking and operational excellence”.

The company, which looks to start its operations during the 2026 harvest, describes itself on its website as “a production and packaging ally for beverage brands”.

Its services include custom crush, bulk wine production, blending, wine-based drinks production and packaging services such as counterpressure canning.

Treasury Wine Estates signaled its intention to sell off some of its facilities in California at its investor day earlier this month.

Speaking to analysts at the event on 4 June, CEO Sam Fischer said TWE had already carried out “a detailed assessment of the demand outlook” in the US, and found its supply chain in California “will require significant changes to correct what is a structural misalignment between capacity and out future state portfolio needs”.

TWE has already started implementing these changes, the CEO then noted. They include reducing the number of growers the company works with and “fallowing a number of vineyards”, as well as selling “elevated levels of luxury wine from recent vintages currently held on our balance sheet” over a longer time period.

Later in the event, the group’s chief supply and sustainability officer Kerrin Petty provided more detail on how TWE plans to make changes in its US supply chain.

In California, as well as cutting its network of growers and fallowing vineyards, Petty said the group was looking to focus on “materially reducing our owned and leased vineyards in Napa, Sonoma and the Central Coast and addressing capacity and utilization of our winery and packaging assets”.

The St. Helena Winery is becoming the group’s “main US luxury production hub”, Perrin said. TWE will move production of Frank Family Vineyards and Stag’s Leap Winery to the site. Its Paso Robles and San Luis Obispo wineries are to be “closed and divested over the course of the next 12 months”, he added.

TWE’s bottling centre in Sonoma will also be reduced in size, “reflecting lower volumes moving through”.

During a question and answer session, interim CFO John Pipito clarified any benefits of these supply chain changes would not form a part of the A$100m cost savings target under the Ascent programme.

Fischer’s “transformation programme” – dubbed Ascent – was first laid out in December. It features a target for cost savings of A$100m (US$71.4m) a year over the next three financial years.

As part of the Ascent initiative, TWE is reviewing its business in the Americas and has plans to cut its product range from 76 to less than 30 brands.
