Coffee Shops, Cafes, Tea Rooms Industry Terminology

Acidity

In specialty coffee, the bright, tart, fruity sensation that gives coffee and tea their liveliness; not the same as low pH sourness. Managed through origin, roast, grind, temperature, and recipe. Often described as citric, malic, phosphoric, or tartaric in sensory notes.

This Kenyan has sparkling acidity with blackberry notes; Lower the brew temperature to tame the perceived acidity; Guests asking for low-acidity options prefer our cold brew and certain teas.

Average Ticket

Average revenue per transaction, calculated as total sales divided by number of transactions. A key KPI for upselling, menu mix, and pricing effectiveness.

Average ticket rose from 7.80 to 8.40 after we added alt-milk upcharges; Baristas, aim to add a pastry to increase average ticket; Our midday daypart has the highest average ticket due to lunch combos.

Barista

A trained coffee professional who prepares espresso, brewed coffee, and tea beverages, while managing quality, speed, hospitality, and cleanliness. Often responsible for dialing-in, milk steaming, latte art, and equipment upkeep.

Our lead barista will dial in the espresso each morning; Train baristas to steam milk to 55-60 C for latte art; A certified barista can manage both speed and quality during rushes.

Brew Ratio

The proportion between the amount of dry coffee used and the beverage produced. For espresso it is often stated as input mass to output mass (for example 1:2), and for filter coffee as coffee-to-water ratio (for example 1:15 to 1:17).

We pulled that espresso at a 1:2 brew ratio, 18 g in and 36 g out; For pour-over we target 1:16 coffee to water by mass; Adjust the brew ratio if the cup tastes weak or too intense.

COGS (Cost of Goods Sold)

The direct cost of ingredients used to make beverages and food, such as coffee, tea, milk, syrups, and pastries. Excludes labor and overhead, and is used to calculate gross margin and menu profitability.
