Caffeine matters—coffee creation method of choice at your startup?

The basic tradeoff seems to be: Quantity + speed vs quality + effort

We still haven't found the right balance. Here's our results so far:

# Nespresso Pros: stupid simple; good-quality espresso Cons: pods are costly and wasteful; can't get quantity you always want

# French press Pros: high quality coffee (when combined with our burr grinder and fresh beans) Cons: takes too much time and effort (set up, operation, cleanup) for every cup

# Melitta / other single-cup drip Pros: basically the same as the French Press Cons: ditto

# Drip coffee pot Pros: easy; mass quantities Cons: haven't found one that makes coffee well enough; doesn't taste good

# Local coffee shop Pros: great coffee Cons: huge fucking waste of everyone's time

The current best alternative I can imagine: ->Create a big-ass french press (size of a small child) and get a massive vacuum-insulated thermos to keep all the coffee warm for quite awhile.

^I mean that only half tongue-in-cheek

Anyone figured out a better solution?
