How To Size A Canning Line For Your Brewery

Start with your real production volume, not your target

The most common sizing mistake is designing a line around where you want to be in five years, rather than where you are now plus realistic near-term growth.

Work out:

• Your current annual production volume in litres or barrels
• How that translates to cans per batch, based on your typical can size (355mL, 375mL, 440ml, etc)
• Your packaging days per week and the hours available per packaging day.

From there, you can calculate the throughput (cans per minute) your line actually needs to clear a batch within your available packaging window, not the maximum throughput a line could theoretically achieve.

Match Line Speed To Brewhouse Output

A canning line that outpaces your brewhouse just sits idle for most of the week. A line that can't keep up with your brewhouse becomes the constraint on your entire production capacity.

The goal is a canning line that comfortably clears your batch size within your packaging day, with some buffer for changeovers, cleaning and unplanned downtime - not a line sized for a hypothetical future brewhouse expansion you haven't committed to yet. As a general guide:

• Small/nano breweries (under ~1000L batches): Semi-automatic or entry-level automatic lines, typically 20-40 cans per minute.
• Mid-sized breweries (1000-5000L batches): Mid-tier automatic machines, typically 40-80 cans per minute.
• Larger production breweries: High-speed automatic lines, 100+ cans per minute, often with multi-head fillers and inline seamers.

These bands are starting points, not rules. Your actual sizing should be calculated from batch volume and packaging window, not read off a chart.

Account For Every Stage, Not Just The Filler

A canning line is only as fast as its slowest stage. Sizing the filler correctly doesn't help if your seamer, labeller or conveyor system can't match that throughput. Work through each stage:

• Filling: Counter-pressure filling is the standard for carbonated beverages, minimising oxygen pickup and foaming. Fill head count should be matched to your target speed; under-specifying fill heads is one of the most common bottlenecks we see in mid-tier lines.
• Seaming: Your seamer needs to match filler throughput, with seam quality tested and verified regularly rather than assumed. A fast filler feeding a slow seamer just creates a queue.
• Labelling: If you're applying labels inline rather than using pre-printed cans, labeller throughput needs to match the rest of the line (see our guide on rotary vs linear labellers for more information).
• Conveying and accumulation: Often overlooked, but accumulation tables and conveyor buffering give your line tolerance for minor stoppages at any single station without halting the whole line.

Build In Realistic Growth Headroom

It's reasonable to size a line with some growth capacity built in. It's a different thing to size a line for growth that's still speculative. A practical approach would be to size for your production volume 18-24 months out, based on actual sales trajectory and committed expansion plans, not best case projections. Most well-built canning lines can also be incrementally upgraded later - additional fill heads, upgraded seamers, added labelling capacity - so you're not locked into a single configuration forever.

Don't Forget Changeover And Format Flexibility

If you run multiple can sizes or pack formats, factor changeover time and tooling cost into your sizing decision. A line that's fractionally faster on paper but takes an hour longer to changeover between SKU's may cost you more in practice than a slightly slower line with quick-change tooling.

Budget Realistically Across The Whole Line

Canning line budgets are often built around the filler and seamer, with labelling, conveying and quality control equipment treated as an afterthought. Price the full line before committing, so you're not caught short mid-installation.

Getting It Right

The right canning line sits at the intersection of your current production volume, your packaging window, your realistic growth trajectory and your budget across the entire line. Q-Pack works with breweries across Australia and New Zealand to size canning lines around actual production data, with equipment sourced from established partners including Matrix SRL. If you're scoping a new line or evaluating whether your current setup still fits your production volume, our team can walk through the numbers with you before you commit to a configuration.
