TECHNICAL REVIEW WINEMAKING ANDREW ADAMS Each tank is equipped with a dedicated pump for pump overs. Barrel fermentations are managed with OxOline racks. tank's self-contained pump-over system means a harried cellar worker can't accidently send the juice from one tank to another. "It truly does eliminate pumpover error," Stambor said. The system can be monitored remotely— and cycles can even be adjusted—although Stambor said he doesn't tend to make any changes when he's not at the winery. He noted the system is rather sensitive and will issue alarms quite often for relatively minor temperature changes. "We're working on that really, on the alarm thing," he said. Stambor said for the majority of lots he'll inoculate with FX10, F15 and some mixed inoculations. He will add some MicroEssentials nutrients as well as diammonium phosphate as needed. An added luxury in the reserve winery is simply time. Stambor said each lot is left in its dedicated tank for as long as the winemakers deem necessary. "In here we don't have to turn any of the tanks. The fruit that comes in here is destined for that tank as long as we want it to be," Stambor said. Each steel tank is insulated and fitted with a 2-inch pipe that runs between the tank and the layer of insulation. A centrifugal pump is located beneath the tank and is fed from a valve opening that is covered with a screen on the rear, interior wall of the tank. The tanks' bottom valve is also screened for draining. The 2-inch pump-over pipe leads to sprinklers that are installed at the tank tops at the start of each harvest. Stambor said the sprinklers provide a gentle wetting and are used during extended maceration as well. Burgstahler Machine Works in St. Helena, Calif., designed and built the pump-over piping and irrigators. The winery is equipped with five Taransaud French oak vats, which are also connected to the same control system. Stambor said the plan is to buy one new oak vat every five years, and he installed the first "renewal" vat in Now all print subscribers get digital access included Scan this mobile barcode or visit winesandvines.com/digitaledition.
