Cold Brew vs Sparkling Tea on Tap: Which Keg Should Your Cafe Add First?
Both cold brew and sparkling tea work great on tap - but they serve different customers and dayparts. Here's how to decide which to start with.
Co-Owner, PourZero
If you can only add one keg to your cafe, start with cold brew if your customers are caffeine-driven, or sparkling tea if they're flavor-and-wellness-driven.
Both products pour well, look great, and have strong margins. But they serve different needs and different dayparts. Here's the full comparison.
Head-to-Head Comparison
| Factor | Cold Brew on Tap | Sparkling Tea on Tap |
|---|---|---|
| Caffeine | High (150-200mg/serving) | Low to none (0-50mg) |
| Best daypart | Morning, early afternoon | All day, especially afternoon |
| Flavor profile | Rich, smooth, chocolatey | Light, floral, fruity |
| Visual appeal | Dark, cascading (if nitro) | Colorful, sparkling, eye-catching |
| Instagram factor | High (especially nitro cascade) | Very high (colors photograph well) |
| Margin | 60-75% | 55-70% |
| Shelf life (tapped) | 2-4 weeks | 4-8 weeks |
| Customer overlap with coffee | High - same customer, same need | Low - new need, new occasion |
| Gas | Nitrogen (best) or CO₂ | CO₂ |
Start with Cold Brew If…
- You already have a coffee-focused identity and want to deepen it
- Your peak traffic is morning and early afternoon
- You want to replace pre-batched cold brew with a more consistent, longer-lasting keg format
- Your customers are primarily caffeine-motivated
- You already have a nitrogen setup (or want that premium cascading pour)
Start with Sparkling Tea If…
- You want to attract new visit occasions beyond coffee
- Your space gets afternoon/evening traffic and you need something non-caffeinated
- You serve health-conscious customers who care about ingredients and wellness
- You want something that looks different from what's already on your menu
- You don't have nitrogen and want to keep it simple with CO₂
The Best of Both Worlds
If you can run two taps, do both. They complement each other perfectly:
- Cold brew covers your morning-to-early-afternoon caffeine customers
- Sparkling tea covers your afternoon-to-evening wellness/social customers
- Together, they give you draft coverage for every daypart
