Gravity vs handpull cask dispense

Last updated: 29 June 2026

Most pub licensees think the choice between gravity and handpull dispense is about what looks better on the bar — it’s not. The real difference is in cellar space, CO2 costs, staff discipline, and how much beer ends up down the drain instead of in a customer’s glass. I’ve run both systems across two pubs, and the financial impact is far larger than most people realise.

Your choice affects cleaning costs, line waste, pouring consistency, and the speed at which your staff can serve during a busy night. It also directly influences stock variance — and a 1% stock loss on wet sales quietly costs a typical pub £3,000–£5,000 a year. Get the dispense method right, and you’re already halfway to controlling it.

This article breaks down gravity versus handpull in terms that matter: upfront cost, ongoing expense, wastage risk, and which one actually fits how pubs run today.

How Gravity and Handpull Dispense Work

Gravity dispense works by positioning the cask above the tap. The weight of the beer itself creates the pressure needed to push liquid through the line and out of the tap. No power, no CO2, no machinery. You tap the cask, connect a soft line, and gravity does the rest.

Handpull (or pump dispense) uses an electric or manual pump to draw beer from a cask in the cellar and push it up to taps on the bar. The pump either forces CO2 into the cask to create pressure, or it actively pulls and pushes the liquid through a closed line.

In theory, gravity sounds simpler. In practice, it’s more fragile.

The Temperature Problem with Gravity

Gravity dispense relies entirely on consistent beer temperature. If your cellar is 15°C one day and 18°C the next, you’ll get variable pouring speed, potential flat beer, and inconsistent head formation. Most cask ales are conditioned to pour best at 11–13°C. Go above 15°C and the cask pressure drops, pouring slows, and your staff starts squeezing the tap harder to compensate — wasting beer and frustrating customers.

Handpull systems are more forgiving because the pump actively maintains pressure regardless of temperature fluctuation. Your cellar can drift a few degrees and the customer still gets a consistent pint.

Handpull Speed vs Gravity Elegance

A handpull tap delivers a pint in seconds at consistent pressure. Gravity pours slower — especially as the cask empties and the liquid column shrinks. On a Friday night with a queue, gravity becomes a bottleneck. Handpull keeps the bar moving.

That said, handpull lines require more frequent flushing and cleaning, and the pump itself is a moving part that can fail.

Cost Comparison: Upfront and Ongoing

Gravity systems have almost no upfront cost. You need a cask stand (£20–£50), a tap tool, and soft tubing — maybe £200 total for a single line. No electricity, no installation, no CO2 equipment.

Handpull setups cost significantly more. A single pump dispense line can run £800–£1,500 installed, depending on cellar layout and whether you’re adding new pipework. Multiple taps multiply that cost quickly.

Ongoing costs heavily favour gravity once you add them up. A handpull system uses CO2, which needs refilling roughly every 4–8 weeks depending on turnover. At current prices (2026), a CO2 cylinder swap costs £15–£25 per fill. That’s £45–£150 per tap per year just for gas. Electricity for the pump adds another £50–£100 annually per line. Gravity costs virtually nothing to operate.

However — and this is critical — many pubs don’t factor in the real cost of gravity: staff time and product loss when the system underperforms. If your cellar isn’t cold enough and handpulls would save a full keg of waste per month, the £100 annual CO2 cost disappears into the noise.

Installation and Flexibility

Gravity is plug-and-play. Move a cask, tap it, pour. Handpull requires permanent pipework, often running from the cellar to multiple bar positions. Retrofitting a pub with new handpull lines is expensive and disruptive.

If you’re in a small, tight cellar with limited space — like many UK village pubs — gravity is the only realistic option. Handpull demands good cellar layout and forward planning.

Wastage and Stock Loss Risk

Here’s where the real money argument lives. Handpull systems waste more beer operationally, but gravity systems hide losses more easily.

Handpull Waste

Every time your staff change a line or purge stale beer from the system, they’re pouring product down the drain. On a busy pub changing lines twice a day, that’s 2–3 pints wasted per tap per day just from line maintenance. Over a week, it adds up to a full keg or more depending on how many handpull taps you run.

The waste is visible and measurable — you can see the beer going out. The problem is that most pubs don’t track it. They treat it as “part of the job.” If you’re losing 5 pints a day from line waste on 4 handpull taps, that’s roughly 35 pints weekly, or 1,820 pints a year. At £3 per pint margin, that’s £5,460 of lost contribution going unnoticed.

Gravity Loss: The Invisible Kind

Gravity systems waste less operationally, but they hide stock loss exceptionally well. If your cellar temperature drifts or a cask develops a slow leak, you won’t notice for weeks. The beer doesn’t disappear in one obvious pour — it seeps out gradually or pours inconsistently while staff assume it’s normal.

I’ve found partial kegs sitting in cellars where the pressure had dropped so low that staff had stopped trying to pour them. The dregs just sat there until we did a count and realised we were short. With gravity, you have to be disciplined about cask inspection and temperature monitoring. With handpull, the system forces visibility because of the regular line work.

The number that actually matters is wet GP by line, not a single headline stock figure. Spirits hide losses in over-pouring (a free-poured 25ml is often 32–35ml), draught hides it in poor cellar temperature and bad line cleaning waste, and most stock ‘theft’ is actually measurement error and forgotten wastage. You need to weigh open spirit bottles, dip every cask and partial keg, and reconcile against till data the same day.

Cellar Space and Practical Constraints

Many pubs have cellars that were never designed for modern equipment. Old village locals with low ceilings, narrow access, or damp walls can’t accommodate the pipework and infrastructure handpull demands.

Gravity works in almost any cellar because you’re just stacking casks on simple stands. It’s flexible, portable, and doesn’t care about space constraints.

If your cellar is already tight, or if you’re in a Grade II listed building where you can’t run new pipes without planning headaches, gravity is the practical answer — but only if you can maintain consistent temperature.

New-build pubs or refurbished venues with proper climate control can run handpull efficiently. Traditional pubs with old cellars usually end up with gravity out of necessity, then struggle with inconsistent pouring.

Which System Wins for Your Pub

The answer depends on four variables: cellar temperature stability, bar speed, product range, and turnover.

Choose Gravity If:

• Your cellar stays between 12–15°C year-round (no summer swings above 16°C)
• You’re a village pub with moderate cask ale turnover, not a high-volume boozer
• You have limited cellar space or can’t install new pipework
• You value simplicity and want minimal moving parts or ongoing costs
• You’re on a tight budget and can’t justify £1,000+ upfront investment

Choose Handpull If:

• Your cellar is warm, humid, or temperature-inconsistent (above 16°C in summer)
• You’re a busy town-centre pub serving 300+ pints of cask per week
• You run multiple cask lines and need consistent, fast pouring
• Your cellar is modern with good layout and climate control
• You can afford the upfront cost and want to eliminate pouring speed bottlenecks on busy nights

In my experience, the real divider is cellar temperature. If you can’t guarantee it stays cool, handpull solves the problem. If your cellar is naturally cold, gravity works fine and saves you money.

Measuring What Actually Matters

Neither gravity nor handpull prevents stock loss on its own. The system you choose only affects how loss happens and how easy it is to spot.

At my own pub I was running stock on a tangle of spreadsheets and still losing track of partial kegs and spirit measures. I built a simple count routine around a dipstick and a set of scales, and the weekly variance went from guesswork to a number I could trust within a fortnight. Once you have a number you trust, you can actually see whether your dispense system is performing.

Most pubs that move from a messy spreadsheet to a disciplined count claw back 1–2 GP points within a couple of months. That’s not because they stopped theft — it’s because they stopped losing invisible stock to measurement error and forgotten wastage.

The StockTap pub stock app automates that process. You dip the cask, weigh the spirit, scan the product code, and the system logs it. Every week you reconcile against till data — same day. Within days, variance patterns become obvious. You’ll see which lines waste the most, which shifts have the biggest shrinkage, and whether your dispense method is actually the problem or whether it’s something else entirely.

Gravity vs handpull is important operationally, but it’s not the root cause of most stock loss. Discipline in counting and reconciliation is.
