Crush Pad Planning: Layout, Utilities & Flow

A crush pad is where grapes arrive, get sorted and processed, and move into fermentation — and it is the single most time-pressured space in the winery during harvest. Plan it around one principle: fruit should move in one direction, from delivery to fermenter, without backtracking or crossing paths. Get the flow, the utilities, and the drainage right and a small team can process a full day's intake calmly; get them wrong and you create bottlenecks that no equipment upgrade fully fixes.

This guide walks through layout logic, the utilities you must size before pouring concrete, and the equipment sequence that connects them.

Start with the flow, not the shopping list

Before you place a single machine, map the path the fruit takes. A clean crush pad follows the natural processing order with no doubling back:

Grape delivery — trucks or bins arrive and are weighed
Receiving and tipping — fruit goes into a hopper or onto a receiving conveyor
Sorting — cluster and/or berry sorting removes MOG (material other than grapes) and substandard fruit
Crushing and destemming — a crusher-destemmer separates stems and, if wanted, breaks skins
Must or whole-cluster transfer — a must pump or gravity moves fruit to press or fermenter
Pressing (whites/rosé) or to fermenter (reds) — pressing happens here or downstream
To fermentation — must arrives at tanks ready to ferment

Design the physical layout so each step sits next to the one before it. The classic mistake is buying good equipment and then arranging it so the forklift has to reverse through the sorting crew to reach the press. Walk the path on paper first.

Gravity vs pumping

Decide early whether you'll move fruit by gravity or by pump, because it changes the building. Gravity-flow designs place receiving and crushing above fermentation so must falls into tanks, which is gentle on the fruit but demands a sloped site or a raised crush deck. Most wineries pump instead, which is more flexible and far cheaper to build — but means choosing must pumps that handle whole berries and stems without shredding them. For a full comparison of pump types, see the winery pumps guide.

Size for peak, not average

The crush pad is sized by your busiest day, not your annual average. During a compressed harvest, several blocks can ripen at once, and a pad built for "typical" intake jams the moment two trucks arrive together. Plan around:

Peak daily intake — the most fruit you might need to process in one day, including custom-crush or contract fruit if relevant- Equipment throughput — your crusher-destemmer and press throughput in tonnes per hour set the ceiling; if the destemmer can clear the day's fruit but the press can't, the press is your bottleneck
Buffer space — room for full bins waiting to be processed and empty bins waiting to be cleaned, so the line never stalls for lack of staging area

A useful check: estimate how many hours your peak intake will take through your slowest machine. If that number runs past a reasonable working day, you need more throughput, more staging, or staggered fruit delivery.

Utilities: get these right before the concrete

Utilities are the part founders underestimate most, and they are the hardest to change later. Size them generously.

Water

Harvest is washdown-intensive. You'll rinse bins, equipment, floors, and hands constantly, so plan for ample hot and cold water with conveniently placed hose stations. Under-sizing water supply or hot-water capacity creates a hidden bottleneck — crews wait to clean, and dirty equipment slows the line.

Drainage and wastewater

This is the detail that separates a workable pad from a miserable one. Crush pads generate large volumes of water mixed with skins, seeds, stems, and lees. You need:

Generous trench or slot drains positioned along the wet zones, not a single floor drain in a corner
Solids capture (catch baskets or a separator) so stems and skins don't enter the wastewater system
Floor slope toward drains so water never pools — pooling means slips, contamination, and standing must

Wastewater handling may be subject to local regulation. Confirm requirements with the relevant authority before finalising the design — this guide is planning education, not compliance advice.

Power

Sorting tables, the crusher-destemmer, pumps, and the press all draw power, sometimes simultaneously. Confirm the electrical supply, phase, and the number and placement of outlets for the equipment you'll run at once — and leave spare capacity for the equipment you'll add as you grow. Retrofitting three-phase power into an existing slab is expensive.

Compressed air

If you run a pneumatic press or air-actuated valves, you need a compressor sized for them and air lines run to the right points. Check the press's air requirement before specifying the compressor.

Layout principles that prevent bottlenecks

One-directional flow. Fruit enters one end, finished must leaves the other. No crossing paths between clean and dirty zones.
Forklift and bin access. Leave clear lanes wide enough for a loaded forklift to turn without disrupting the sorting crew. Bin traffic is constant during harvest.
Cleanable surfaces everywhere. Sealed concrete, stainless, and smooth surfaces. Every hour spent cleaning is an hour not processing.
Covered but ventilated. Shade keeps fruit and crew cooler and protects equipment from sun and rain, while open sides keep CO2 from fermentation and processing from accumulating.
Equipment on wheels where possible. Mobile sorting tables and pumps let you reconfigure the pad between white and red processing, or between vintages as volumes change.
Staging space at both ends. Room for incoming full bins and outgoing empties so the line is never starved or blocked.

A simple equipment sequence

Here is how the equipment connects, in order, for a typical pump-over (non-gravity) pad:

Stage	Equipment	Planning note
Receiving	Hopper / receiving conveyor	Sized to your peak bin-tipping rate
Sorting	Sorting table (vibratory or optical)	Crew space and good light; optical adds throughput at higher cost
Crush/destem	Crusher-destemmer	Throughput sets the line speed; size for peak
Transfer	Must pump + hoses	Gentle handling of whole berries and stems
Pressing	Press	Often the real bottleneck — match capacity to intake
To fermentation	Hoses / gravity to tanks	Short, direct runs reduce must handling

FAQ

What is a crush pad in a winery? A crush pad is the working area — often covered and outdoors or in an open-sided building — where grapes are received, sorted, crushed, and destemmed before the must moves into fermentation. It is the busiest, most time-pressured space in the winery during harvest, so it is designed around fast, clean, one-directional fruit flow.

How big should a crush pad be? Size it for your peak harvest day, not the annual average, because several blocks can ripen at once. Allow space for the equipment line, staging for full and empty bins at both ends, and clear forklift lanes. The bottleneck is usually staging space and the slowest machine's throughput, not floor area alone.

What utilities does a crush pad need? Plenty of hot and cold water for constant washdown, generous trench drainage with solids capture and a sloped floor, adequate electrical supply and outlets for equipment running simultaneously, and compressed air if you run a pneumatic press or air-actuated valves. Size all of them with spare capacity for growth.

Should a crush pad use gravity or pumps? Most wineries pump must, because gravity-flow designs require a sloped site or a raised crush deck and cost far more to build. Gravity is gentler on the fruit, so quality-focused producers favour it where the site allows. If you pump, choose must pumps that move whole berries and stems gently rather than shredding them.

Bottom line

A good crush pad is designed flow-first: fruit moves one direction from delivery to fermenter, sized for the peak day, with water, drainage, power, and air specified generously before the concrete is poured. Get those fundamentals right and modest equipment runs smoothly; get them wrong and the best machines still bottleneck. Your next step: map your fruit flow on paper, then match equipment throughput to your peak intake.
