# Best Commercial Iced Tea Brewer for Cafes (2026): The Bunn TB3Q
Josh Caliguire · Oct 12, 2026
I research everything I recommend. As an Amazon Associate, I earn a small commission on purchases through my links. Your price stays the same, and I get to buy more tea. Win-win.
If you run a cafe, restaurant, or coffee shop and want to serve fresh-brewed iced tea all day, **the best commercial iced tea brewer for most businesses is the Bunn TB3Q**. It brews 3 gallons at a time from real tea leaves, fits under most cabinets, and is the machine you'll find behind the counter at a huge number of restaurants.
Bunn invented the commercial fresh-brewed iced tea brewer back in 1978, and it still owns this category. So the real question is which Bunn fits your volume and your menu. Here's how I'd pick:
Serving hot tea too, or still deciding what kind of brewer you need? Start with the bigger picture: [Blog: Commercial Tea Brewers](https://www.joshcaliguire.com/blog/commercial-tea-brewer?hsLang=en).
- **Best for most cafes and restaurants:** Bunn TB3Q (3 gallons per batch)
- **Best for high volume or sweet and unsweet:** Bunn TB6 Twin (6 gallons across two dispensers)
- **Best for tea and coffee from one machine:** Bunn ITCB-DV
- **Best for multiple tea recipes:** Bunn ITB Infusion Series
## Why a Real Iced Tea Brewer Beats Brewing by Hand
Plenty of shops start by steeping tea in a pot and pouring it into a pitcher. It works until you get busy. A commercial brewer fixes the three things that hurt you at volume:
**Consistency.** The brewer runs the same water, temperature, and time every batch. Your iced tea tastes the same on Tuesday morning as it did on Saturday night, no matter who's on shift.
**Labor.** Load a filter with tea, press one button, walk away. The brewer pushes hot water through the leaves and dilutes the batch for you, straight into a dispenser with a spigot.
**Better tea.** Fresh-brewed from real leaves tastes far better than powder or bag-in-box concentrate, and customers notice. If you want to turn tea into a real menu item, I wrote more about that in [Blog: How to Upgrade the Way You Sell Tea](https://www.joshcaliguire.com/blog/how-to-upgrade-the-way-you-sell-tea-and-why-its-worth-it?hsLang=en).
## How to Choose a Commercial Iced Tea Brewer
**Volume.** Start with how much iced tea you pour on your busiest day. A 3-gallon brewer covers most cafes and small restaurants. If you're refilling all afternoon, or you serve both sweet and unsweet, go to a 6-gallon twin.
**Plumbing and power.** These are automatic brewers that connect to a water line. The TB3Q's spec sheet lists a 1/4 inch flare water inlet, 20 to 90 PSI, and a standard 120V plug. **Pull the spec sheet for your exact model before you order** and send it to your plumber and electrician.
**Height.** Measure under your cabinets. The TB3Q is about 29 inches tall, and the brewer has to clear the dispenser lid underneath it.
**The dispenser.** Most Bunn tea brewers **do not include a dispenser**. Budget for at least one, and two if you want a backup batch ready (more on that below).
**Tea and coffee needs.** If you also brew coffee into airpots or carafes, one machine that does both can save counter space.
## 1. Bunn TB3Q 3-Gallon Iced Tea Brewer: Best for Most Businesses
This is the workhorse. The TB3Q brews **3 gallons of iced tea per batch** directly into a dispenser and can turn out up to 26.7 gallons an hour. The "Q" stands for Quick Brew, a shorter brew cycle than Bunn's standard model, which matters when you run out at lunch.
It stands about 29 inches tall, so it fits under most cabinets. A SplashGard funnel keeps hot liquid away from your staff's hands when they pull the brew basket.
If you serve one house iced tea and want it reliable, consistent, and fast, this is the one I'd buy. [Check price on Amazon](https://www.amazon.com/dp/B00345WZVU?tag=joshcaliguire-20).
## 2. Bunn TB6 Twin Iced Tea Brewer: Best for High Volume and Sweet/Unsweet
The twin brewer sits two dispensers side by side under **a rotating brew basket**. Brew into the left, swing the basket, brew into the right. That's 6 gallons on the counter at once.
This is the setup you see at barbecue joints and Southern restaurants for a reason: **sweet tea on one side, unsweet on the other**, or a black tea and a seasonal flavor. It's also the right call if one 3-gallon batch disappears before your next one is ready.
You can find the [Bunn TB6 Twin here](https://www.amazon.com/dp/B003SO2AJO?tag=joshcaliguire-20), and Bunn also makes a Quick Brew version, the [Bunn TB6Q](https://www.amazon.com/dp/B003SNYOE4?tag=joshcaliguire-20).
## 3. Bunn ITCB-DV Iced Tea/Coffee Brewer: Best for Tea and Coffee
If counter space is tight and you brew both iced tea and coffee, this is the one. The ITCB-DV has **a flip tray with three positions**, so the same brewer fills a tea dispenser, an airpot, or a thermal carafe.
You also get a digital display, three brew buttons with two batch sizes (so you can program different recipes), an energy-saver mode for slow hours, and a display that reads in English, Spanish, or French for your staff. "DV" means dual voltage, so it can run on a standard 120V circuit or a higher-voltage 120/208-240V circuit for faster recovery. Ask your electrician which you have.
Stock on this one moves around, so [check availability on Amazon](https://www.amazon.com/dp/B07CNXCYQG?tag=joshcaliguire-20).
## 4. Bunn ITB Infusion Series: Best for Multiple Tea Recipes
The ITB is the tea-only version of the ITCB, built for shops that take tea seriously. It uses **pre-infusion and pulse brewing**, so it wets the leaves first and then brews in stages, which gets more flavor out of good tea. It has digital temperature control, three brew buttons, and two batch sizes.
Pick this if you rotate several iced teas (a black, a green, an herbal) and want each one dialed in with its own recipe. It's sometimes out of stock on Amazon, so [check the Bunn ITB listing](https://www.amazon.com/dp/B084SRJ8D5?tag=joshcaliguire-20) for current availability.
## Don't Forget the Dispenser and Filters
The brewer fills a dispenser, and your customers or staff pour from its spigot. **Buy two**, so one batch is ready to swap in while the other gets washed.
**Bunn TDO-4:** a 4-gallon oval dispenser with a brew-through lid (the brewer pours straight in, no lid juggling), a sump valve that drains every last drop, and a faucet handle labeled "sweetened" and "unsweetened." It's made for the TB3 series. [Bunn TDO-4 Iced Tea Dispenser](https://www.amazon.com/dp/B075DKFWQM?tag=joshcaliguire-20).
**Bunn TDO-N-3.5:** a narrow 3.5-gallon version with 8 inches of cup clearance and front-to-back handles that save counter space. It fits the TB3, TB3Q, ITB, and ITCB brewers with a 29-inch trunk. [Check price on Amazon](https://www.amazon.com/dp/B00HQ0A642?tag=joshcaliguire-20).
**Filters:** stock Bunn's own paper filters. A [500-count box of Bunn tea and coffee filters](https://www.amazon.com/dp/B00NWTE8YA?tag=joshcaliguire-20) lasts a long time. Confirm the filter size in your brewer's manual before you order.
## Tips for Better Iced Tea at Scale
**Start around 1 ounce of loose black tea per gallon.** That's a common commercial starting point. Taste, adjust, then write your recipe down so every shift brews it the same way. Pre-portioned iced tea filter packs make this foolproof.
**Use quality tea.** Bulk loose leaf from a good supplier costs pennies per glass and tastes miles better than the cheapest option. Store it sealed and away from heat and light; the same rules from [Blog: Best Tea Storage](https://www.joshcaliguire.com/blog/tea-storage?hsLang=en) apply at any size.
**Sweeten while it's hot.** For sweet tea, add sugar to the dispenser before you brew so it dissolves in the hot concentrate. Sugar dumped into cold tea sinks to the bottom.
**Don't let it sit too long.** Most food safety guidance and brewer manuals say to **discard brewed iced tea after about 8 hours** and clean dispensers and faucets daily. Label each batch with the time it was brewed. Check your local health code for the exact rule.
**Descale on a schedule.** Hard water scale is what kills tea brewers. A water filter on the line and regular deliming keep your brewer running for years.
Want the brewing science behind all this? [Blog: Why Is My Tea Bitter? It's Time and Temperature](https://www.joshcaliguire.com/blog/time-and-temperature?hsLang=en) explains why over-steeping turns tea harsh, and that matters even more at 3 gallons.
## Just Making Iced Tea at Home?
Everything above is commercial equipment, and it's overkill for a household. For home, a countertop iced tea maker like the [Brentwood KT-2150](https://www.amazon.com/dp/B07RM6Y4WM?tag=joshcaliguire-20) brews a pitcher in minutes, or skip the appliance entirely with my [Blog: How to Make Iced Tea with Loose Leaf Tea](https://www.joshcaliguire.com/blog/how-to-make-iced-tea-with-loose-leaf-tea?hsLang=en) method. If you already own a Bunn coffee maker, it brews tea too: put loose tea in a paper filter, and brew double strength over a carafe half full of ice.
## Commercial Iced Tea Brewer FAQ
**How much loose tea do you use per gallon of iced tea?**
About 1 ounce of loose black tea per gallon is a common starting point. Adjust to taste and keep it consistent.
**How long can brewed iced tea sit in a dispenser?**
Most guidance says to discard it after about 8 hours and clean the dispenser daily. Follow your local health code.
**Do commercial iced tea brewers need plumbing?**
Yes. Automatic brewers like the TB3Q connect to a water line. Check your model's spec sheet for the water and electrical requirements.
**Can I use a home iced tea maker in a cafe?**
For a few glasses a day, maybe. Once iced tea is a real menu item, a commercial brewer pays for itself in labor and consistency.
## The Verdict
For most cafes and restaurants, buy the **Bunn TB3Q** and two dispensers. If you pour a lot of iced tea or serve sweet and unsweet, step up to the **TB6 Twin**. If you need tea and coffee from one footprint, get the **ITCB-DV**.
For hot tea, pair it with a good hot water source: [Blog: Best Water Boiler for Tea](https://www.joshcaliguire.com/blog/best-water-boiler-for-tea?hsLang=en).
**Homework:** before you order, measure the height under your cabinets, find the nearest water line, and check your outlet. Those three numbers decide which brewer actually fits your shop.
