If you’ve ever reached for your favorite insulated tumbler on a cold day, only to pause mid-step because you’re craving a warm, spiced hot toddy, you’re not alone. As a tumbler supplier who’s spent the last decade talking to customers about their daily hydration and drinkware needs, this question comes up more than you’d think: “Can I use a tumbler for a hot toddy?” Tumbler

At first glance, it’s a fair question. Hot toddies are cozy, comforting, and designed to be sipped slowly—often over 20 or 30 minutes (or even longer, if you’re stretched out on the couch with a book). A traditional toddy is made with hot water, honey, lemon, a cinnamon stick, a clove or two, and a shot of whiskey, rum, or bourbon, so it’s a steaming, acidic, sometimes sugary concoction that needs to stay at a drinkable temperature for as long as possible. That’s where tumblers shine, right? But before you dump your toddy into your go-to stainless steel cup, let’s break this down with both practical experience and the science of how tumblers work, because not all tumblers are created equal—and not all hot toddy needs are the same.
Let’s start with the basics of how a good insulated tumbler keeps drinks hot. Most high-quality tumblers (the kind we supply) use double-wall vacuum insulation. The vacuum layer between the inner and outer walls of the cup removes air, which is what normally transfers heat from hot liquids to the cooler surrounding air via convection. The inner wall is almost always stainless steel, too, which is non-porous, resistant to rust, and far less likely to react with acidic or sugary drinks than, say, plastic or low-grade aluminum. For hot drinks, this insulation works wonders: we test our tumblers by filling them with boiling water at 212°F (100°C), sealing them, and leaving them at room temperature (around 72°F/22°C) for six hours. On average, the water inside still clocks in at 140°F (60°C) after six hours—plenty hot for a perfectly enjoyable toddy, and way above the “danger zone” temperature of 40°F to 140°F (4°C to 60°C) where bacteria grow quickly. That’s a big win for anyone who wants to nurse a toddy through a chilly afternoon or evening.
But wait—hot toddies have unique components that regular hot coffee or tea doesn’t, and that’s where some folks run into issues. Let’s talk about acids first. Lemons are a staple in any hot toddy, and citric acid is a mild but consistent presence here. For years, there was a myth that acidic drinks would react with stainless steel tumblers, leaving a metallic taste or even leaching harmful chemicals. That’s not quite true for food-grade 18/8 stainless steel, which is the material we exclusively use for our tumblers (it’s the standard for commercial food and drink vessels, tested and approved by global health and safety bodies). The chromium in 18/8 steel forms a tight, protective oxide layer on the inner wall that prevents acid from seeping into the metal. We’ve run 24-hour acid soak tests on our tumblers as part of our quality control process, and even after 24 hours of sitting with a 5% citric acid solution (way more concentrated than lemon juice, which is only about 2-3% citric acid), there’s no detectable leaching, and the taste of a toddy made in the tumbler is indistinguishable from one made in a traditional glass mug. The only catch here is that if you leave lemon residue sitting in your tumbler for days (not hours), the citric acid can dull the exterior finish over time—so a quick wash after use is all it takes to avoid that. That’s easy enough, right?
Next, there’s the issue of sugary syrups and honey, which are also common in hot toddies. Honey is hygroscopic, meaning it attracts moisture, and sugar can build up in small crevices—especially around the seal of the tumbler’s lid. If you’ve ever had a sugary coffee stuck in the rim of your tumbler, you know this can be a minor hassle, but it’s not a safety issue. Our tumbler lids are made with BPA-free Tritan plastic, which is resistant to sugar and honey residue, and the silicone gaskets we use are food-grade, so they won’t absorb or react with sweeteners. That said, I always advise customers to take an extra minute to rinse the lid and gasket right after finishing a toddy, rather than letting it sit for days. It’s not about damage to the tumbler—it’s about making sure your next drink doesn’t get a weird, old honey aftertaste.
Now, let’s address the elephant in the room: the alcohol. Whiskey, rum, and bourbon are lower-proof spirits, so they’re not going to cause any kind of reaction with stainless steel or the other materials in your tumbler. The high-proof spirits (100 proof or higher) won’t either—there’s no material in our tumblers that will break down from alcohol. That’s another common concern I hear from customers, but after working with bartenders who use our tumblers for craft cocktails on the go, I can confirm that this is a non-issue as long as you have a quality lid. A good vacuum-sealed lid is key for a hot toddy, because it keeps steam from escaping (which would cool your drink down fast) and prevents spills if you’re carrying it from the kitchen to the couch, or to a friend’s house for a cozy night in. Our lids are designed to be leak-proof when closed tightly, and easy to sip from when you’re ready to take a drink—no fumbling with a separate lid for your toddy.
But let’s not pretend there are no caveats here, because if I’m being honest, not every tumbler is right for a hot toddy. I’ve seen customers grab thin, single-walled tumblers from gas stations or discount stores and be disappointed when their toddy is lukewarm after an hour. That’s not the tumbler’s fault—it’s the insulation. Single-walled tumblers don’t have the vacuum layer, so heat transfers right out into the air. Those are fine for cold drinks, but hot drinks need double-wall vacuum insulation to hold temperature. Also, lids matter: a thin, flimsy lid that doesn’t seal properly will let steam escape, so your toddy will cool down quickly. Another thing to watch out for is tumblers with decorative finishes on the inside. Some lower-quality tumblers have a non-stick or painted interior that can react with acidic drinks over time, but that’s not a problem with food-grade stainless steel like what we use.
Let’s talk about real-world use cases, because that’s what matters most. Last winter, I had a regular customer who worked from home as a freelance writer. She told me she used to make her hot toddy in a regular ceramic mug, but she’d get up to make coffee or stretch her legs, and by the time she came back, her toddy was cold. She bought two of our 16oz tumblers specifically for hot toddies, and she emailed me three weeks later saying it was a game-changer. “I make my toddy at 9 a.m., write for two hours, take a break for lunch, and it’s still steaming hot when I’m done,” she wrote. That’s exactly the kind of feedback we love. Another customer, a bartender at a cozy downtown restaurant, started using our 20oz tumblers for take-home toddies during the pandemic. He told me that even when customers drove 20 minutes to pick up their orders, the toddy was still at 130°F (54°C) when they arrived—hot enough to enjoy without burning their tongues, and way better than the to-go paper cups that would go cold in 10 minutes.
Now, let’s cover a few common mistakes people make when using a tumbler for a hot toddy. First, don’t pre-heat your tumbler? Wait, actually, that’s a good tip. If you want to maximize the heat retention, you can fill your tumbler with hot water for 30 seconds before adding your toddy, dump that water out, then add your hot drink. That pre-heats the inner wall of the tumbler, so it doesn’t draw heat out of your toddy. It’s a small step, but it can add 30-60 minutes of temperature retention, which is perfect for a long toddy sipping session. Another mistake: over-filling your tumbler. If you fill it all the way to the top, there’s no space for the steam, which can cause pressure to build up when you seal the lid, leading to a slow leak. Fill it to about ¼ inch below the rim, leave a little room at the top, and that avoids any issues. And finally, don’t put your tumbler in the microwave. A lot of people don’t realize that stainless steel (and most tumbler lids) can spark in the microwave, so if you need to reheat your toddy, pour it out into a microwave-safe glass or mug. That’s a safety tip, not a flaw in the tumbler.
As a tumbler supplier, my goal isn’t just to sell you a cup—it’s to make sure you’re using it in a way that works for your favorite drinks, and that means being honest about what our products can and can’t do. The short answer to “Can I use a tumbler for a hot toddy?” is a resounding yes—if you choose a high-quality, double-wall vacuum insulated tumbler made with food-grade 18/8 stainless steel and a sealed, BPA-free lid. That said, if you’re using a cheap, single-walled tumbler, you’re going to be disappointed because your toddy will cool too fast. If you’re using a tumbler with a non-food-grade interior, you might end up with a metallic taste from the lemon or honey. That’s why we put so much time into testing every tumbler we supply—we want you to be able to use it for your morning coffee, your afternoon iced tea, and your evening hot toddy, no matter the drink.
I’ll be the first to admit that I didn’t always get this right. Early in my career, I sold a line of lower-cost tumblers that were great for kids’ water bottles and casual use, but they didn’t have the insulation to hold a hot toddy for more than an hour. We got so many customer complaints about toddies going cold that we reworked our entire product line, invested in vacuum insulation technology, and started testing every tumbler for hot drink retention. That experience taught me that the best tumblers aren’t one-size-fits-all—they’re built for the specific needs of the people who use them, and for many of us, that includes a warm, spiced toddy on a cold night.

If you’re someone who loves making hot toddies for yourself or for friends, and you’re tired of lukewarm drinks that go bad before you can finish them, we’ve got you covered. Our tumblers come in a range of sizes (12oz for a single serving, 20oz for a toddy to share, and even larger sizes for people who want extra liquid) and a variety of finishes, so you can pick one that fits your style.
