For an office mainly drinking black coffee, start with a batch brewer such as the BUNN VP17-1. For an office regularly requesting espresso and milk drinks, consider a one-touch machine such as the JURA W8. Count the busiest fifteen minutes before choosing either: a daily rating does not tell you how long the morning queue will be.
Two concrete options
Model | Manufacturer information | Fits when | Check before ordering |
|---|---|---|---|
BUNN VP17-1 stainless, 13300.0001 | 12-cup pourover brewer, one lower warmer, no plumbing; servers sold separately | The office wants batches of black coffee and can manage serving and refills | Batch volume, compatible servers, counter space and electrical supply |
JURA W8 Dark Inox, NAA 15650 | One-touch drinks; recommended maximum daily output of 50 | Espresso and milk drinks are regular requests and someone owns the cleaning routine | Peak drink sequence, refills, milk cleaning and local service |

Translate capacity into your own mugs
Do not read a 12-cup brewer rating as twelve 12 oz mugs. Confirm the actual batch volume and server. For a hypothetical 60 oz batch, five 12 oz mugs exhaust it; a different confirmed batch volume changes that calculation.
Likewise, the W8's 50-drink daily recommendation does not establish a fifteen-minute capacity. Ask a seller to demonstrate your actual mix of drinks, with the required refills and cleaning included. If 18 people arrive together, the waiting time matters even when the whole day's demand is below the recommended maximum.
A demand worksheet before you request a quote
Count actual daily drinkers (N) and drinks per drinker (D): daily drinks = N × D. Observe the fraction of those drinks requested in your busiest hour (P): peak-hour drinks = N × D × P. Count hot-water requests too when they use the same tank.
For a hypothetical 20 drinkers taking 2 drinks each, with half requested in the busiest hour, that is 40 drinks per day and 20 in that hour. At an assumed 250 mL each, the hour uses 5 L of water before any cleaning or flushing. These are worksheet inputs, not a capacity claim for either machine. Milk, refills and cleaning can change the queue; check your actual fifteen-minute burst as well.
Write down who refills water and beans, who cleans the milk system, and who covers an absence. Ask the supplier to demonstrate the measured peak with your drink mix, then confirm installation, service access and warranty coverage for shared-office use. A daily rating alone cannot establish the peak throughput.
Assign the jobs around the machine
For batch coffee, decide who buys filters and coffee, fills water, manages servers and disposes of stale batches. For milk drinks, decide who stores milk safely and completes the manufacturer's cleaning routine. If neither task has an owner, the equipment will not solve the office's coffee problem.
Check installation and servicing before comparing price. Confirm the circuit, counter clearance, access for refills, repair provider and warranty terms. A low initial quote can become inconvenient if the machine must be shipped away for every repair.
Work out running cost
Use your actual coffee dose and prices. For illustration only, $18 for a 340 g bag at 18 g per drink is about $0.95 of coffee. Add assumed filters and electricity of $0.06. A hypothetical $2,000 machine used for 50,000 drinks contributes $0.04 per drink; $40 annual descaler over 10,000 drinks contributes $0.004. That makes about $1.05 before milk. An assumed $0.40 of milk brings it to about $1.45.
These are arithmetic inputs, not BUNN or JURA prices or measured running costs. Substitute your own values in the coffee cost-per-cup calculator.
Make the decision
Choose the batch option when black coffee covers the regular demand and you can serve batches promptly. Choose the one-touch option when milk and espresso demand justify the purchase and daily cleaning. If the morning peak is concentrated, verify that peak before choosing either machine; do not substitute the manufacturer's daily rating for a queue test.
