A Winery’s Annual Case Count Does Not Describe Its Peak Cooling Needs
By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.
Two wineries can produce the same annual number of cases and require different cooling arrangements. The difference may be when production happens, which operations occur together and the conditions under which the equipment must perform.
For a buyer, an annual case figure is therefore an incomplete description of a production facility. It should be connected to the operating schedule and the actual refrigeration system before it becomes an assumption about future capacity.
Cooling is part of production capacity
Oregon State University’s Energy Efficiency Center identifies fermentation cooling and refrigeration as major winery energy considerations. Its discussion also highlights controls and seasonal compressor demand. These are general engineering considerations, rather than a design specification for any Napa or Sonoma property.
The acquisition implication is straightforward: inspecting tanks without understanding the system serving them leaves an important part of the facility unexplained. Equipment that is physically present may serve different loads at different times.
Compare the calendar, not just the annual total
Imagine two hypothetical operations, each planning twelve identical batches. One schedules six batches in each of two periods. The other schedules three batches in each of four periods. Their annual batch counts match, while the maximum number scheduled in one period differs by a factor of two.
This example does not calculate a refrigeration load; batch size, temperature, weather, equipment and other factors would be needed for that. It illustrates why annual throughput alone cannot establish the peak operating demand.
Separate equipment condition from system suitability
A technician may find a particular unit in serviceable condition. A separate engineering question is whether the installed arrangement suits the purchaser’s intended program, including simultaneous uses and the conditions under which they occur.
Similarly, a recent equipment replacement does not explain every part of the installation. Distribution, controls and the relationship between equipment and served loads still matter. Obtain the appropriate technical evaluation for the proposed operation instead of treating a model number as a complete answer.
The proposed wine program can change the comparison
A buyer planning a different production mix, harvest schedule or client-service operation should describe that plan before relying on historical performance. A system’s operating history under the seller’s program is useful evidence about that program. It is not automatically a demonstration of a materially different one.
Keep the supported historical operation and the intended future operation in separate scenarios. If an expansion requires additional equipment or other work, show the anticipated scope and cost without presenting it as already installed capacity.
Operating expense needs matching production context
A low annual electricity bill could reflect efficient operation, limited production or another circumstance. Compare bills with the periods and activities they cover. Dividing an expense by cases is informative only when the numerator and denominator concern the same operating period and scope.
For example, a hypothetical $24,000 expense divided by 12,000 cases is $2 per case. The same expense divided by 8,000 cases is $3. Those invented figures show how utilization changes a unit comparison even before any equipment efficiency change is assumed.
Connect the system review with the purchase budget
The resulting acquisition model should distinguish routine operating expense, immediate work and any future change needed for the buyer’s program. That makes it easier to compare a facility that fits the intended operation with one requiring an additional investment.
