For office parties, plan about 1.3 drinks per guest, one barista per 60–80 guests, and a menu of 5–6 drinks including chai. Diwali and year-end dates fill fast — book 3–4 weeks ahead.

At a glance: the numbers that matter
Start here. These four figures answer most of what planners ask us in the first phone call about a beverage counter for office parties, and the rest of this guide explains how each one moves.
- Drinks per barista-hour
- 60–80
- Sustained on a commercial two-group machine
- Counters at peak
- 1 per 250
- One counter per 250 guests arriving in the same window
- Drinks per guest
- 1.3
- Across 4 hours; two scheduled breaks pushes it to 2
- Setup window
- 90 minutes
- Machines need 20 minutes to reach brew temperature
In short: one barista on one commercial machine sustains 60–80 drinks an hour. Plan one counter per 250 guests arriving in the same window, 1.3 drinks per guest across four hours, and a separate chai queue to take roughly 40% of the load off the espresso machines.
Counters, baristas and throughput by guest count
Capacity planning is arithmetic, not instinct. A barista on a commercial two-group machine sustains 60–80 drinks an hour once the queue is steady, and everything below works back from that figure at 1.3 drinks per guest across a four-hour window. For office parties: Diwali and year-end dates fill fast — book 3–4 weeks ahead.
| Guest count | Counters | Baristas | Peak drinks per hour | Service window |
|---|---|---|---|---|
| Up to 100 | 1 | 2 | 120–160 | 3–4 hours |
| 100–300 | 2 | 3–4 | 200–320 | 4 hours |
| 300–800 | 3 | 5–6 | 350–480 | 4–5 hours |
| 800–2,000 | 5 | 8–12 | 600–900 | 5–6 hours, staggered |
| 2,000+ | 6 or more | 12+ | 900+ | Multi-zone with shift rotation |
Figures assume a commercial two-group machine per counter and a separate chai or non-coffee queue, which typically absorbs 40% of Indian event demand. Conference agendas with two sharp breaks push consumption towards two drinks per guest — size for the peak, not the average.
Recommended setup
Festive office parties with coffee, mocktails and cheer. Most clients combine these services:
- Mocktail Bar
- Cold Brew Bar
- Live Coffee Bar
Staffing and timing
Align service with the event's peak moments and confirm final numbers 72 hours before.
How to size a beverage counter for office parties for your guest count
Here is the sequence we walk clients through, in the order the decisions actually have to be made.
- 1
Find your peak, not your headcount
Step 1Work out how many guests reach the counter in the same 20 minutes. A 500-guest conference breaking all at once is a far harder job than a 500-guest wedding spread across four hours.
- 2
Convert guests into drinks
Step 2Plan 1.3 drinks per guest across a four-hour window. Agendas with two scheduled breaks, late-night functions and winter events all push that towards two drinks per guest.
- 3
Divide by barista throughput
Step 3One barista on a commercial two-group machine sustains 60–80 drinks an hour. Divide your peak-hour drink count by 70 to get the number of barista-and-machine pairs you actually need.
- 4
Split the queue before it forms
Step 4Put chai or the non-coffee option on its own counter. In India it reliably absorbs around 40% of demand, which is cheaper than adding a second espresso machine to carry the same load.
- 5
Stage for the peak and brief the crew
On the dayShare the agenda so milk is steamed, cups are stacked and staff are at the counter before sessions break. Most visible queues are a staging failure rather than a capacity failure.

How we measured these throughput numbers
These are operator numbers, not market research. 5,000+ events and 2.5M+ cups since 2016, across 60+ cities, is the dataset behind this page — which also means the numbers carry our own assumptions, listed plainly below.
- ●Throughput timed on live counters rather than taken from machine manufacturer claims
- ●Drinks-per-guest ratios counted from cups served against confirmed headcounts
- ●The coffee-to-chai split measured across Indian corporate and wedding events
- ●Counter counts validated against events where queues formed, and against events where they did not
What the quoted rate includes
- Commercial espresso machine and grinder
- Trained, uniformed baristas
- Beans, milk, syrups, cups and consumables

- Travel, transport and stay for venues outside city limits, charged at cost
- Venue-supplied floor space, 16A power points and water access
- Overtime beyond the booked service window, billed hourly
- Menu items outside the agreed list, and print production beyond the standard counter wrap
