Your beer deserves better than a growler that goes flat.
Most growlers are glorified glass jugs. This one is double-wall vacuum insulated with a copper lining — the same tech used in premium coffee thermoses, sized for your local brewery fill.
- 64 oz capacity — standard US growler size, fits all brewery fill stations
- Double-wall vacuum insulation — keeps beer cold 24 hours, hot drinks hot 12 hours
- Copper-lined interior — prevents metallic taste that stainless steel can leave
- Wide mouth — easy to fill, easy to clean, easy to add fruit or hops
- Leak-proof screw cap — toss it in your bag on the way home from the brewery
The difference you'll taste: Copper doesn't react with beer like stainless does. Your IPA will taste as fresh at hour 20 as it did at the taproom. And unlike glass, this won't shatter if you drop it.
What's in the box: 64oz growler, stainless steel screw cap with silicone seal, cleaning brush.

The Story Behind Insulated Growler
The growler problem
Standard glass growlers are fragile. Stainless ones make your beer taste like metal. We wondered: why can't a growler keep beer as fresh as a high-end coffee thermos keeps coffee hot?
Copper isn't just for show
Copper has natural antimicrobial properties and doesn't impart metallic flavors like stainless steel. We partnered with a Korean vacuum-flask manufacturer to create a triple-wall insulated body with a copper-plated interior.
Tested at 12 breweries
We sent prototypes to 12 craft breweries across the Pacific Northwest. The feedback was unanimous: beer stayed carbonated and fresh longer than any other growler they'd tested. One brewery started using them for their own crowler program.

What Customers Say
Frequently Asked Questions
Will this fit under a standard brewery tap?+
Yes. The height is 9.5 inches — standard brewery taps have 12+ inches of clearance. Just remove the cap and fill directly.
Can I put carbonated drinks in it?+
Absolutely. The screw cap creates a pressure-tight seal that maintains carbonation better than a swing-top growler. Tested with sparkling water — still bubbly after 48 hours.
Does the copper lining require special care?+
Not really. Rinse with warm water after use. For deeper cleaning, use a dedicated bottle brush with mild soap. Avoid abrasive scrubbers. The copper is plated and sealed — it won't tarnish.
Is this safe for hot liquids?+
Yes. The triple-wall vacuum insulation keeps hot liquids hot without the exterior getting too hot to hold. Tested with boiling water — exterior stays comfortably warm, not burning hot.
What's the return policy?+
30-day risk-free guarantee. Not happy with how it keeps your beer? Send it back. Free return shipping, no questions asked.
