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.
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
