bladder press external pressure is applied by pressurized air (rarely water) that gradually inflates the membrane that gently presses the grapes against the drain screen. The advantage of this style of press is the gentle pressure and minimal movement of the grapes, which minimizes the amount of tearing and scouring of the skins and seeds. This limits the amount of suspended solids and extracted phenolics in the pressed wine. Also, many membrane presses are fully enclosed, allowing for anaerobic winemaking without any exposure to oxygen. In addition to the same labor and time disadvantages (some presses can take 2 to 4 hours a batch) of the other batch presses, these computerized and enclosed membrane press are often some of the more expensive pieces of equipment a winery can buy.
212: 347: 899: 515:- Grapes are loaded into an input where a large helical screw transfers the grape across perforated cylinder that allows the release juice to escape. As screw moves further down, the cake pomace is subjected to increasing pressure. While the advantage is the high throughput, the harsh pressing and movement cause tearing and grinding of the grape skins and seeds, causing more minerals (such as potassium, which can affect pH), tannins and natural gums to be extracted into the juice. As much as 4% v/v of the pressed juice from a screw press could be suspended solids that may need to be treated by clarification and fining agents to be stable and filterable. 676: 115: 20: 531:- This press utilizes a series of air-inflated pads along a wire mesh belt. Usually several meters long, fresh grapes are loaded onto the beginning of the belt where it is transferred by rollers through the series of pads that apply pressure, hold it for a time and release with the juice falling through the screens into waiting press pans. Belt presses have been used by high volume wineries for whole-cluster pressing and sparkling wine production but it has not caught on in many wine regions due to concerns about the amount of 545: 431: 1583: 458:
as the heads are retracted. While less labor-intensive than traditional basket presses and providing more even pressure, one disadvantage of the moving head press is that it that cake gets so compact that it is often difficult for juice to strain from the inner core of the cake out. This has the effect of creating a dry "outer cake" and wet "inner cake" with trapped juices still inside. The juice extracted from the dry outer cake can also be very coarse and high in phenolics.

auger screw or belt) that transfers the grapes through the pressings with an output area for the discarded cake. The throughput is limited by the capacity of the tank and the diameter of the screw or width of the belts. Many models of continuous screw presses can process from 50 to upwards of a 100 metric tonnes an hour. This can be a significant advantage for a high volume winery compared to batch presses that often only process 1 to 5 tonnes an hour.
919:) will use this type of pressing to avoid harsh tannins or "green-ness" that may come from under ripe grapes. This method is different from "stem pressing" where the grapes are crushed and destemmed but portions of the stems are saved and tossed into the wine press to add some phenolics as well as create "channels" for the juice to drain between the skins, which can limit how often the drain screens get clogged. 228: 372:
However, batch presses are much more labor-intensive, requiring repeated emptying and filling and can also be more time-consuming, often requiring between 1 and 2 hours per press cycle. Continuous presses, which are often used by high-volume wine producers, can be more efficient, with some continuous screw presses having the capability of doing upwards of 100 metric

loaded on top of each other in a press. Even among press juice there are compositional difference between the various "fractions" of juice produced from initial pressing through subsequent (and usually harsher) pressing.

The amount of pressure applied (and speed) will depend on the winemaker's preference with additional pressure increasing the likelihood that the skins and seeds of the grapes will be scoured and torn, releasing tannins and other phenolic compounds that could make the juice more astringent and bitter.

There are many different styles of batch presses ranging from simple hand-operated basket presses to computerized membrane presses and presses that are "opened" with oxygen able to come into contact with the must or "enclosed" in a tank

with these solids that will make the wine difficult to stabilize. Some winemakers will use pectolytic enzymes during the maceration process to help break down the cell walls to allow the release of more juice freely. These enzymes are also used with white wines to assist in clarification. The type of

The timing of pressing and the methods used will influence other decisions in the winemaking process. In white wine making, pressing usually happens immediately after harvest and crushing. Here, the biggest decision will be how much pressure to apply and how much pressed juice the winemakers wants in

Winemakers often keep their free-run juice and pressed wine separate (and perhaps even further isolate the wine produced by different pressure levels/stages of pressing) during much of the winemaking process to either bottle separately or later blend portions of each to make a more complete, balanced

Instead of providing pressure from the center out like with a bladder press, the membrane of a membrane press is mounted on one side of the press horizontally between the two ends. On the opposite ends are drain screens that allow the release juice to drain through into the waiting press pan. Like a

An advantage of this style of press is the usually gentle means that it presses the grape but its disadvantages includes the labor intensiveness of its use, small volumes and tendency to provide uneven pressure to all parts of the cake

Another advancement was the complete enclosure of the press (sometimes called "tank press") that reduced the exposure of the grape must

The benefit or rotating the tank or breaking up the cake is to promote a more even pressing and formation of a regular-shape cake that will be easier to move. From the moment that grapes are filled into the tank or basket, juice is being released and extracted. This juice is usually drained by the

The benefits of continuous presses is the "continuous" sequence that allows large volumes of grapes to be pressed with minimum labor involvement. Instead of pressing separate batches that need to be emptied and refilled, continuous press typically have an input area and some mechanism (such as an

In the 20th century, wine presses advanced from the vertical style pressing of the basket press and ancient wine press to horizontal pressing with pressure either being applied at one or both ends or from the side through use of an airbag or bladder. These new presses were categorized as "batch",
371:
In general, batch presses are considered more "gentle" with less movement of the grape skins that minimize the amount of tearing of the skins. The more the grape skins are torn or scoured, the more phenolic compounds and tannins that are extracted, which can increase the harshness of the wine.

as well as usually exposing the must to significant amounts of oxygen. Another disadvantage from a time perspective but an advantage in other regards such as gentleness, is that by its nature pressing with a basket press is very slow. Applying too much pressure too rapidly can break the press.

Under the whole-cluster method, the first press fraction is essentially the "free-run" fraction since the grapes berries are only first being broken and releasing juice as the press cycle begins. However, like with the pressing of crushed grapes the composition of the juice changes with each

Usually the pressed juice will require some additional treatment, which can be done separately to the pressed juice alone or to the entire batch of wine if the pressed juice is blended with the free-run. These treatments may include acid adjustments to lower pH, extended settling periods for

While not as varied as batch presses, there are three main types of continuous presses, each with their own benefits and disadvantages. While often more common in the juice industry than in winemaking (and are even banned for quality wine production in some wine regions such as

land tenants were willing to pay a portion of their crop to use a landlord's wine press if it was available. This was likely because added volume of wine (anywhere from 15 to 20%) that pressing could produce versus manual treading was substantial enough to justify the cost.
