The Espresso Martini is the #1 cocktail on bar menus right now. It's also one of the slowest to make — 90 seconds minimum per drink when made scratch. That's 40 drinks per hour maximum from one bartender. At $18 per cocktail, that bottleneck is costing you real money every night the house is packed.
Here's the thing: the guests don't care how it gets made. They care that it's cold, frothy, and in their hand fast. The solution is batching it on draft — and once you do the math, you'll wonder why you waited.
The Math That Changes Everything
Let's put real numbers on the table. One bartender, one station, one cocktail. Here's how the three methods stack up:
| Method |
Time per drink |
Drinks/hour |
Revenue/hour at $18 |
| Scratch (shake per order) |
90 sec |
~40 |
$720 |
| Pre-batched (shake per order) |
45 sec |
~80 |
$1,440 |
| Draft keg (pour and serve) |
~15 sec (pour + garnish) |
~240 |
$4,320 |
That's not a typo. Draft puts 10x+ the revenue potential in reach. Even at 20% of that capacity during a busy shift, you're looking at a dramatically different P&L. And your bartenders aren't exhausted from shaking espresso martinis all night.
The key is a batching-grade cold brew concentrate — one that's calibrated for cocktail ratios so you're not improvising in the back with bags of ice and a prayer. That's exactly what Top Hat Cold Brew Coffee Concentrate is built for.
Five Coffee Cocktails Built for the Tap
Below are five recipes we've developed and tested specifically for batch-and-draft service. Each one is designed to scale cleanly, hold quality across a keg, and pour consistently from the first glass to the last. Start with one. Once your regulars find out, you'll wish you'd put two taps on.

The Balboa Cafe Espresso Martini: A San Francisco Icon Built on Draft
In 2017, we activated an Espresso Martini on draft program at the Balboa Cafe in San Francisco using our Cold Brew Coffee Concentrate. What happened next wasn’t something we planned for — it became a phenomenon.
The Balboa Cafe Espresso Martini is now on travel itinerary lists for visitors to San Francisco. They sell branded “Tini Time” t-shirts and hats. And the program running on our cold brew concentrate — the same concentrate you can order right now — delivers:

Espresso Martini on Tap
The OG that started the whole coffee cocktail moment — and the one your guests are going to order five times tonight. Batched with Top Hat Cold Brew Coffee Concentrate, vodka, and simple syrup, then force-carbonated and served on draft, it's everything your guests love: that deep espresso flavor, silky foam, perfect chill. No shaker. No wait. No bottleneck.
Key Ingredients
Top Hat Cold Brew Coffee Concentrate
Batch-calibrated cold brew for cocktail ratios. Rich, consistent, no guesswork.
Top Hat Simple Syrup
Rich 2:1 pure cane sugar syrup. Balances perfectly in batch without over-sweetening.
Top Hat Agave Nectar
Ultra-premium mouthfeel — warm, earthy agave that adds depth and silkiness.
Carajillo on Tap
The Carajillo has been quietly taking over cocktail menus from Mexico City to Miami — coffee and Licor 43, served cold, impossibly smooth. It's a two-ingredient drink that punches way above its weight and has some of the highest bar margins you'll find. On draft, it goes from ordering to hand in under 10 seconds. If you serve a Latin-leaning crowd, this is a no-brainer addition to the tap lineup.
Key Ingredients
Top Hat Cold Brew Coffee Concentrate
The coffee backbone of your Carajillo batch. Bold, smooth, ready to scale.
Top Hat Simple Syrup
Adds that subtle sweetness to round out the Carajillo without fighting the Licor 43.
Top Hat Agave Nectar
Ultra-premium mouthfeel — warm, earthy agave that adds depth and silkiness.
Café Coquito on Tap
Think of the Café Coquito as your seasonal weapon — a creamy, coconut-and-coffee batched cocktail that turns heads, sells itself, and has the kind of Instagram appeal that turns into table-to-table orders. It's Puerto Rican eggnog meets cold brew: coconut cream, condensed milk, rum, and Top Hat Cold Brew Coffee Concentrate. Batch it, keg it, and watch it disappear. This one earns its tap handle.
Key Ingredients
Top Hat Cold Brew Coffee Concentrate
Deep coffee flavor that holds its own against coconut cream. Consistent batch after batch.
Mexican Espresso Martini (Tequila/Mezcal)
Swap the vodka for tequila or mezcal and you've got a completely different cocktail — smokier, more complex, with that agave backbone cutting right through the cold brew. This one plays especially well at cocktail bars with a spirits-forward identity. If you've already got a tequila-heavy menu, this is the obvious draft addition that ties your program together. Guests who find it love it loudly.
Key Ingredients
Top Hat Cold Brew Coffee Concentrate
The coffee foundation that holds its own against the boldness of mezcal or blanco tequila.
NOLA Espresso Martini
New Orleans brought us café au lait and chicory coffee — this is what happens when that tradition meets a modern bar program. The NOLA Espresso Martini layers cold brew with chicory bitters and a whiskey or rum base for a richer, more complex flavor profile than your standard espresso martini. It's a great way to position a premium draft cocktail at a higher price point. Give guests something they can't get anywhere else.
Key Ingredients
Top Hat Cold Brew Coffee Concentrate
Rich cold brew that plays beautifully with chicory notes and a whiskey base.
Level Up: Serve Your Espresso Martini, Carajillo or Café Coquito on NITRO
There's draft — and then there's nitro draft. Add a nitrogen infuser to your setup and your Espresso Martini, Carajillo, or Café Coquito will pour with that slow, cascading waterfall effect: dense, velvety foam that settles into a glass-half-dark, half-cream pour. It's theatrical. It's Instagrammable. And it transforms your bar program from "efficient" to "a whole experience."
Nitrogen naturally suppresses carbonation and creates that signature creamy mouthfeel — it's the same science behind a Guinness tap, applied to your coffee cocktail program. Once guests see their neighbor get a nitro espresso martini with that cascading pour, you're selling two at a time.

Frequently Asked Questions
What equipment do I need to batch espresso martinis on draft?
At minimum: a commercial keg (typically a 1/6 or 1/4 barrel Cornelius-style "corny" keg works great for cocktails), CO₂ tank and regulator, a draft tower or tap handle, and refrigeration to keep the batch cold. Most bars already have the refrigeration infrastructure — the cocktail keg setup is an add-on. For nitro, you'll swap CO₂ for a nitrogen tank or a CO₂/N₂ blend. We can walk you through the full equipment spec — just reach out.
How long does a batched espresso martini keg last?
A properly batched and kegged espresso martini will hold quality for 2–3 weeks refrigerated under pressure. The key is keeping dairy out of the batch (no cream liqueurs) and keeping it cold. Once you tap it, plan to turn it within a week for best flavor. If you're running events, plan to kill a keg the same day — draft cocktails for events are typically batched fresh the day before or morning of.
