The next generation of destemmers features new methods for removing MOG as well as variable settings for speed and motion that enable winemakers to further customize how they process grapes on the crush pad. Many of these machines feature optional crushers and additional sorting capabilities. 

Armbruster Rotovib

The Armbruster Rotovib employs a patented vibratory movement to “pluck” grapes from the stems, allowing thorough berry removal at slower speeds. Destemmed berries fall onto the next stage of sorting, while unripe grapes and raisins stay affixed to the rachis and move into the waste stream. A new “Rollersorter” add-on feature provides additional mechanical sorting with interlaced silicon rubber spools that carry berries toward the collection point while allowing MOG to fall through as waste. The machine is available in three models with throughput rates of 10-30 tons per hour. Distributed through Scott Laboratories. Price for Rotovib 10 with Rollersorter: $32,500.

Bucher Vaslin

The Delta Oscillys machine by Bucher Vaslin uses inertia to separate grapes from the stems. Grapes enter the machine through a small hopper and fall into cylindrical cages that swing back and forth. The movement forces berries to separate from the stems, and they then fall onto a rolling sorter table. The manufacturer claims the Oscillys produces a grape stream of just 0.2% to 0.5% MOG. Throughput is 2 to 16 tons per hour and can be adjusted by the size of the cage holes and swinging speed. Price for Oscillys 100: $42,000; Oscillys 200 with two destemming cages: $56,000.

C.M.A. Dream

C.M.A. unveiled its new Dream machine in 2015. The Dream is fed through a hopper and uses a swinging cage system to separate whole berries, which fall onto a rolling sorting table that further separates out MOG. The holes of the sorting cage and the swinging speed can be adjusted for grape size and quality. Throughput of the Dream is between 1 and 15 tons per hour. Distributed through Prospero. Starting price: $39,000.

Dinamica

Dinamica expanded its line of crusher-destemmers this year. The company now offers a range of models that can process from 3-6 tons per hour to 18-25 tons per hour. The destemmers feature adjustable legs to fit into any crush pad system and optional crushing rollers. The crusher is powered by a separate motor and can be operated independently from the destemmer, allowing it to be placed at the end of a sorting table. Distributed by TCW Equipment & Systems. Starting price: $5,995.

IMMA

The new i10 by IMMA can be adjusted in multiple ways, depending on grape size, berry condition and winemaking goals. The speed of the beater bars and cage revolutions can be adjusted as well as the height of the cage and distance between the bars and cage. Other features include a crusher that can operate as a separate unit and an interior jet system to make cleaning and sanitizing easier. Throughput is 10 tons per hour. Distributed by The Vintner Vault. Price: $21,500.

Milani Estasi

The belt-fed Estasi machine by Milani “brushes” berries off stems by coupling the forward motion of the belt with a “transverse oscillating screen.” The machine is designed to be gentle to preserve as many whole berries as possible. The machine also features rubber rollers to be used as an optional crusher.

Pellenc

The Pellenc Selectiv’ winery system uses three patented mechanisms for destemming and sorting. Grapes first pass through a linear, high-frequency destemmer, in which clusters are pulled between vibratory destemming modules along a grid conveyor that allows whole berries to fall through to a rolling sorter table. The rollers let berries fall into a collection auger, while any remaining MOG is carried to a separate channel. Pellenc offers three models that have throughputs of between 4 and 20 tons per hour on hand-harvested clusters. Starting price: $49,450.

SOCMA

Featuring a small footprint that allows it to easily be incorporated into a crush pad, the Cube by SOCMA employs a vertical destemming process that uses flexible, vibrating “fingers” that remove grapes as they fall through a hopper. The destemmed grapes then move along a vibratory table that removes stems, raisins and other MOG before reaching SOCMA’s “Viniclean” sorting rollers, which separate the final stream of sorted berries from MOG.
