While the rest of beer contracts, hard tea keeps climbing. It has been the standout growth engine of an otherwise shrinking category — and as producers and co-packers scale it across faster lines and lighter cans, one thing quietly decides whether that growth holds up on the shelf: consistent can pressure. That is exactly where liquid nitrogen dosing earns its keep.
The one segment still growing
The 2025 numbers tell a hard story for beer overall. U.S. beer production and imports fell roughly 5.7%, and total domestic beer dollar sales slipped about 3.3% to $24.5 billion for the year. Even flavored malt beverages (FMBs) — the category that had been carrying beer — dipped around 3.6% to $4.6 billion, with hard seltzer continuing its long slide.
Against that backdrop, hard tea stands out. It jumped roughly 18% in multi-outlet channels in 2024 and has compounded at about 22% a year since 2021, making it the fastest-growing corner of FMBs and now the category's second-largest segment. Led by brands like Twisted Tea, hard tea has become the clearest — and in many stretches the only — reliable growth story in the beer aisle. For anyone specifying a packaging line today, it is the format worth building for.
Why can pressure is the make-or-break variable
Nearly all hard tea ships in aluminum cans, and the pressure inside those cans is not incidental — it is engineered. A precise dose of liquid nitrogen added just before the lid is seamed flashes to gas, expanding to roughly 700 times its liquid volume. That expansion pressurizes the can from the inside and purges oxygen from the headspace. Get it right and the can is rigid, protected and shelf-stable. Get it inconsistent and the problems show up fast:
- Too little pressure — cans panel, dent and feel soft, seaming suffers, and rejects climb as containers move down the line and onto the truck.
- Too much pressure — ends dome and cans buckle or fail, creating scrap and safety concerns.
- Variable oxygen pickup — an uneven purge means uneven dissolved oxygen, which shortens shelf life and lets flavor and aroma drift from can to can.
For a fast-scaling category, that consistency isn't a nicety — it's what keeps a growing brand's quality identical across every batch, line and co-packer.
Consistency comes from dose-to-dose repeatability
Consistent can pressure is really a question of consistent dosing: the same precise amount of liquid nitrogen, in every can, at full line speed. That is what JoyCan's dosers are built to deliver, and a few features matter specifically for hard tea:
- Repeatable, precise doses — tight dose control holds can pressure in spec container after container, so the last can of a run measures like the first.
- Gaseous nitrogen purge — prevents frost and ice buildup around the nozzle, the most common cause of drifting doses and inconsistent pressure over a long shift.
- Variable dosing for linear fillers — on multi-head craft lines, the CryoDoser Flex Craft Custom tailors the dose to each container, so every can gets the right charge even as it passes the fill heads at a different moment.
- Right-sized nozzles — matched to your can and fill so the dose lands where it should without splashing or shortfalls.
Built to grow with the category
Hard tea producers span the full range — from a craft brewer canning a few SKUs to a national brand running high-speed co-packing. JoyCan's lineup scales with them: the UltraDoser 150S for craft and pilot lines up to 150 CPM, the CryoDoser Flex Craft Custom up to 200 CPM with variable dosing, and the UltraDoser 2KA and CryoDoser Flex Pack Premier for high-throughput lines up to 2,000 CPM. And because reliable internal pressure adds strength to the package, dosing also lets fast-growing brands lightweight their cans — trimming material cost and carbon as volumes climb — without sacrificing durability.
Hard tea is where the beer category is growing. Consistent can pressure is how you make sure it keeps growing on your line.
