On bar now · OZBREW Coffee Roaster
Tomorrow's coffee was dropped by a regular.
Regulars and roasters drop sealed bags at the café. The guest coffee changes whenever a bag runs out or the freshness window expires. The café keeps count of the grams used daily. Regulars earn points as their bag is used, and roasters are paid on an invoice for each bag once it comes off the bar.

The gram log
Every gram, weighed.
At closing, the café puts each guest bag on its scale and saves the weight. What the bag lost since the day before is that day's grams used, whatever the brew, dial-in and beans sold by weight included. Past days are locked, and whoever dropped the bag can see every one of them, and what the bag has earned, at any time.
How one bag's grams get counted: the bag on the café's scale, the café's screen, and the contributor's screen
At closing
The guest bag goes on the scale. Nobody counts doses during the rush.
On the bar page
The café types in the number. BeansDrop takes it from yesterday's weight, and that's the day's grams used. Past days are locked.
