COLD LASTS. FLAVOR STAYS.
Some drinks are worth doing right. The craft pour at the end of a long day. The cold brew that should taste like cold brew three hours in. The 32oz you filled at the start of an afternoon that's only halfway done. Glass won't hold up to any of that. The HydroJug Stein will.
It's a 32oz insulated beer mug shaped like a proper stein and built like modern drinkware: triple-wall vacuum insulation to keep drinks cold for hours, and a ceramic-lined interior to keep every sip tasting exactly like what you poured.
Most steins look the part but fall short on performance. Traditional glass steins go warm fast. Plastic holds off-flavors. The HydroJug Stein is built differently – a 32oz vacuum insulated beer stein made from 18/8 stainless steel with a ceramic-lined interior that keeps beverages cold without transferring any metallic taste. Whether you're filling it with cold brew, a craft beer, or iced coffee, you get the drink the way it's meant to taste.
Triple-wall vacuum insulation keeps the cold you put in from going anywhere – holding temperature longer than glass, longer than plastic, longer than single-wall steel. The rubber base absorbs impact and keeps it planted on any surface. The sturdy ergonomic handle is sized for a real grip on a full 32oz pour.
The ceramic lining inside the HydroJug Stein isn't a detail – it's what separates a true insulated beer mug from a stainless steel cup shaped like one. Standard stainless steel interiors can affect flavor over time, especially with acidic or carbonated drinks. The ceramic coating creates a neutral barrier between the steel and your beverage, so every sip is clean, unaltered, and exactly what you poured.
HydroJug builds the same ceramic-lined technology into the Coffee Traveler and the Everyday Tumbler for exactly this reason – material matters when it's the last thing your drink touches before your mouth. The Stein applies that same standard to a 32oz pour, so the flavor integrity holds from the first sip to the last.
Most insulated mugs use double-wall construction. The HydroJug Stein goes one further with triple-wall vacuum insulation – an additional layer of thermal protection that makes a real difference at 32oz capacity. The more liquid you're holding, the more insulation you need to keep the bottom of that pour as cold as the top was when you filled it.
The powder-coated exterior adds grip, resists condensation on the outside, and handles the kind of daily use that comes with a mug you actually reach for. No sweat rings. No slipping.
The HydroJug Stein 32oz was built for settings where you're holding your drink for a while. Tailgates. Game days. Backyard sessions. Camping trips. Anywhere you'd rather refill once and stay present than keep running back for more. For single cans on the same occasion, the HydroJug Can Coolers cover the rest of the spread.
It also works as a daily carry. The 32oz capacity is just as practical for cold brew and iced coffee at your desk as it is for a cold pour at a gathering – pair it with the Everyday Tumbler for a full desk-to-outdoor setup. And if you're looking for a gift – a large insulated mug with a proper grip and real performance specs – the Stein is a straightforward answer.

Everything worth knowing about the HydroJug Stein 32oz – from what's inside it to how it holds up.
The HydroJug Stein 32oz combines triple-wall vacuum insulation with a ceramic-lined interior – two features most insulated mugs don't have together. The ceramic lining preserves the true flavor of whatever you pour, whether that's beer, iced coffee, or cold brew. The triple-wall construction extends cold retention beyond standard double-wall mugs. Built from 18/8 stainless steel with a powder-coated exterior, ergonomic handle, and rubber base, the Stein is designed for performance and a genuine drinking experience.
Both. The HydroJug Stein is shaped like a traditional beer stein and functions as a fully insulated beer mug – triple-wall vacuum insulated, ceramic-lined, and built from 18/8 stainless steel. It holds 32oz and is designed for cold beverages: beer, iced coffee, cold brew, water, or anything you'd pour cold and want to stay that way.
The HydroJug Stein 32oz uses triple-wall vacuum insulation, which outperforms standard double-wall mugs for cold retention. Exact times vary based on ambient temperature, liquid temperature, and how often the mug is opened, but triple-wall construction is specifically designed to extend cold retention significantly beyond single or double-wall options – and well beyond glass or plastic alternatives.
