The Two Silo Winery is a boutique winery, wine tasting room, and storage facility.

SIP construction helped one of the owners' goals to try to be as sustainable as possible. After visiting with Enercept National Sales Manager, Joe Pasma, about the benefits of SIP construction, owners Jan and Keith Dehnert, liked the concept. Specifically, they like the idea of having an energy efficient building and the speed of construction that SIP Jumbo Panels provide.

SIP wall thickness and core material: 5 1/2" EPS Core
SIP roof thickness and core material: Main roof: 9 1/2" EPS Core; Attic Floor over barrell room: 11 7/8" EPS Core

The benefits of using SIPs, as installer Ryan Larson testemony, the combination of SIP Jumbo Panels with wide-span Starwood Rafters saved a huge amount of time. The total SIP installation took about 3 weeks. Ryan has been installing SIPs since 2007. He puts up an average of 7-8 SIP projects each year.

As per innovative design elements, in the center of the building there are two barrel rooms with a SIP roof or attic floor. Because the Starwood Rafters could not clear these enclosed rooms, a special multi-ply truss was needed to carry the roof load. The barrel rooms are fully encased in SIPs to help control the temperature and humidity. There is also a circular concrete bar in the main tasting area designed to reflect the imagery of the two silos located on the property.

HVAC: The building is heated with radiant in-floor heat, zoned to meet the needs of the public areas, storage area and barrel rooms. They also have a forced air system and central air units that are rarely used.

All of the sheetmetal used in the design was recycled from an old machine shed that was located where the current building stands.
The wood boards climbing the height of the walls came from an 1800's barn that was located on an Amish farm in southern WI.

The Dehnerts purchased the 22-acre dairy farm in 2017. Jan comes from a Greek background. Her grandpa used to make wine. After consulting with an expert on cold hardy grapes, they decided to start a winery. In the vineyard they grow 2,300 vines. They blend their grapes with grapes grown in Lodi, CA. In 2023 they produced 16,000 bottles of wine. When she is sharing the story of the winery building with others, Jan calls it her, "405 piece, 3-dimensional puzzle". They absolutely loved the SIP process and were on hand most days to watch the construction. One feature of the winery that Jan is happy with, are the NanaWalls that fold to open - bringing the outside in.
In addition to the winery, there is an original farmhouse that is rented out as a 5-bedroom resort that accomodates up to 12 guests.
