Frequently Asked Questions About Coffee Catering Supplies

How much coffee do I need for a 2-hour event with 100 guests?

For a 2-hour event serving approximately 100 guests, you'll typically need about 4 pounds of coffee beans. This assumes each guest will consume 1-1.5 drinks on average, with some guests having multiple servings while others may not drink coffee at all. Our calculator provides a more precise estimate based on your specific drink rate.

‍

What's the most common mistake coffee caterers make with supplies?

The biggest mistake we see is underestimating milk quantities, especially alternative milks like oat and almond. Many caterers are surprised by how quickly non-dairy options are consumed at events. Our calculator factors in standard percentages for different milk types based on current consumer preferences.

‍

How much extra should I pack as a buffer?

We recommend a 10-15% buffer on most supplies. Our calculator already factors this into the recommendations. For high-stakes events like weddings or corporate functions, consider increasing your buffer to 20% for peace of mind.

‍

What supplies do mobile coffee caterers most commonly forget?

Beyond the obvious coffee and milk, caterers often underestimate:

Water needs (both for brewing and handwashing)
Ice quantities for cold drinks
Napkins (plan for 1.5-2 per drink)
Stirrers and straws
Backup equipment parts like portafilter gaskets

How do I adjust for different types of events?

Different events have different consumption patterns:

Morning corporate events: Higher coffee consumption, more black coffee requests
Afternoon events: More specialty and flavored drinks
Evening events: Higher percentage of decaf and non-dairy options
Outdoor summer events: More cold drinks and higher ice requirements

Use our calculator as a starting point, then adjust based on your specific event details.
