Until they're topped up with beer and shipped out to retailers, they won't earn Winder Forrest, co-founder of the Crafts Brewery, any money. But she says the business was forced to hoard the cans.
"We are now sitting on a good three months of stock as an insurance policy," she explains.
The firm used to keep just one month's worth supply of cans in stock but given the turbulence in the 'aluminum' market, she is worried suppliers will not be able to meet delivery dates.
The price of the containers has risen roughly 18%, a headache for Ms Forrest and her colleagues, who have also faced soaring delivery costs.
Aluminum is used in a bewildering variety of products - from door frames to aircraft.
While the benchmark price for aluminum traded on the London Metal Exchange has dropped back in the last two months, it remains more than 65% above pre-pandemic levels. Demand for aluminum fluctuated during the pandemic. Sales of the metal fell at the start during lockdowns as workers had to stay at home, but then ratcheted up again as many countries exited lockdown, says U day Patel, senior research manager at Wood Mackenzie.
That left stocks of aluminum in warehouses depleted.
Russia's invasion of Ukraine has tightened supplies further and pushed the price higher still.
"A lot of buyers of aluminum in Europe are almost self-sanctioning and refusing to touch Russian aluminum if they can," says Mr Patel.
But even prior to the conflict, soaring energy prices were already causing headaches at aluminum smelting facilities - the invasion worsened the situation.
US firm Alcoa recently decided to shutter one smelting facility in Spain for two years, until 2024, because of what it called "exorbitant energy prices". Other smelters have shut down or reduced output in recent months, too.
Mr Patel says consultancy, Wood Mackenzie, estimates that Europe will lose about 900,000 tonnes of primary aluminum production in 2022.
"Unlike some other base metals, aluminum is highly susceptible to shifts" in energy prices, says Keith Wilde, head of trading at metals recycling firm, Romeo Group.
This is because nearly half of the price of primary aluminum comes from the energy costs incurred in producing it, he says. The electrolysis process, is energy intensive - electricity is used in the extraction of aluminum from aluminum oxide, which itself comes from the aluminum ore, or bauxite, mined out of the ground.
It is difficult to overstate how important aluminum is to the global economy, it is vital in the production of energy efficient vehicles, for instance. This is what Colin Shore, managing director at Dudley's Aluminum, a Welsh manufacturer of windows, doors and facades, says he has found himself telling his clients recently about the cost of his core material.
"I've been in the industry 30 years," he tells BBC News. "I've not ever seen anything like this in terms of the instability of the raw material price."
Mr Shore products go into all kinds of buildings, from schools to police stations. But one major hotel chain, he says, is putting an upcoming project on hold because of the rising cost of materials.
And at the same time, businesses are facing other cost increases that compound the aluminum problem.
Back in Nevada, Ms Forrest, for one, explains that she used to routinely buy her cans from a supplier in California.
"It was about $300 (£239) to ship one pallet of cans to us," she says. "We ordered another pallet of cans, five days later, it was $3,000… That was shocking."
CraftHaus has since switched to ordering cans from a supplier based closer to home instead - to try and ensure shipping costs remain manageable for the firm.
