Quick answer: Choose a commercial iced tea brewer by volume (gallons per hour), brewing method (dedicated tea brewer or a coffee/tea brewer with tea settings), dispenser type and ease of cleaning. Brew at about 195°F for 3–5 minutes, hold brewed tea no more than 8 hours, label every dispenser with brew and discard times, and clean the brewer, dispenser and faucet daily.
Key takeaways
- Brew hot: about 195°F for 3–5 minutes.
- Hold ≤8 hours, then dump.
- Clean daily, including faucets.
- Label every batch with brew and discard times.
Why iced tea needs rules
Iced tea feels low risk, but tea leaves can carry bacteria, and brewed tea sits at room temperature in dispensers for hours. Food Safety News, citing CDC guidance, notes that tea leaves may carry coliform bacteria and recommends brewing at 195°F for 3–5 minutes, storing no longer than 8 hours and cleaning brewers, dispensers and faucets daily. Sun tea is higher risk because it never gets hot enough.
Brewer types
| Type | How it works | Best for |
|---|---|---|
| Dedicated iced tea brewer | Brews concentrate, then adds dilution water | High-volume tea programs |
| Coffee/tea combo brewer | Tea settings on a batch brewer | Cafés with moderate tea volume |
| Infusion brewers | Precise steeping with programmable recipes | Specialty and flavored teas |
| Manual (kettle + pitcher) | Brew concentrate, dilute and chill | Very low volume |
What to look for
- Capacity: gallons per batch and per hour for your peak
- Dilution control: consistent strength batch after batch
- Temperature control: reaches the right brewing temperature
- Dispenser compatibility: sizes that fit your counter and fridge
- Cleanability: removable sprayheads, funnels and faucets
- Certification: NSF certification covers sanitation design and cleanability
Dispensers
- Clear dispensers show freshness and color.
- Faucet design matters; easy-to-disassemble faucets clean faster.
- Lids should fit tightly.
- Labels or dry-erase tags for brew and discard times.
Daily cleaning routine
BUNN's cleaning guide for its ITCB tea and coffee brewer is a good model. It calls for daily cleaning and sanitizing of funnels, tips, screens, dispensers and faucets, with faucet parts soaked in sanitizer for at least 10 minutes, plus weekly sprayhead cleaning.
- Empty and rinse the dispenser.
- Disassemble the faucet.
- Wash all parts with detergent and a brush.
- Rinse.
- Sanitize at the label concentration; chlorine's effectiveness depends on concentration, temperature and pH.
- Air dry.
- Clean the brew funnel and spray area.
Weekly and monthly
- Remove and clean the sprayhead.
- Inspect and replace worn faucet seals.
- Descale per the manufacturer and your water hardness.
Holding and labeling
| Step | Rule |
|---|---|
| Brew | ~195°F, 3–5 minutes |
| Label | Brew time and discard time (brew + 8 hours) |
| Hold | Covered dispenser; follow local code on temperature |
| Discard | At discard time, even if tea remains |
| Never top off | Don't add fresh tea to old tea |
Sweetened and flavored tea
- Sweeten after brewing with liquid sweetener or simple syrup so it dissolves evenly.
- Flavored teas and fruit additions may need refrigeration; follow your health department's guidance.
- Offer unsweetened as a default with sweetener on the side; many customers prefer it.
Cost per glass
Illustrative 16 oz iced tea:
| Item | Cost |
|---|---|
| Tea (portion of a 1 oz bag per gallon) | ~$0.08 |
| Cold cup, lid, straw | ~$0.20 |
| Ice and water | ~$0.03 |
| Total | ~$0.31 |
At $3.25, that's under 10% cost, making iced tea one of the most profitable drinks on the menu, as long as you're not dumping half-full dispensers every day. Brew smaller batches more often if you're discarding a lot. Cost yours with our cost per drink guide.
Right-size your batches
The biggest cost in an iced tea program is usually waste, not tea. Track how much you dump at each discard time for two weeks. If you're regularly pouring out a third of a dispenser, switch to smaller batches brewed more often, or use a smaller dispenser during slow seasons. In summer, the opposite problem appears: running out at noon. Plan a second brew before the lunch rush and keep tea bags pre-portioned so any barista can start a batch in seconds.

Clear cups for a clear drink
Iced tea looks best in clear cups. Affogato Bean prints branded clear cold cups and lids with design help included. See products or request samples.
Follow your local health code for brewing, holding and cleaning.
Frequently asked questions
How long can iced tea be held in a café?
CDC guidance reported by Food Safety News recommends holding brewed iced tea for no more than 8 hours. Label dispensers with brew and discard times and follow your local health code.
What temperature should iced tea be brewed at?
The CDC guidance recommends brewing tea at 195°F for 3–5 minutes. Avoid sun tea, which brews at lower temperatures and is higher risk.
How often should an iced tea dispenser be cleaned?
Clean and sanitize the brewer funnel, dispenser and faucet daily. Manufacturer guides, such as BUNN's for its ITCB brewer, also call for disassembling and soaking faucet parts in sanitizer.
