A downtown San Antonio floor can pour a perfect morning espresso and still ruin cold brew by 3 p.m. The mix did not shift. The room did. After lunch, many cubes empty and the VAV drifts. The pantry, a small interior room, climbs. Kegs and opened milk sit in a space that feels like a closed car.

We already write about afternoon drink-mix swings on hot days. This is the thermostat and the pantry geometry. Alamo Heights and Stone Oak campuses feel it when the HVAC is zoned for offices, not for a closed kitchen.

Measure pantry temperature, not outdoor temperature

A 100-degree afternoon on the River Walk does not automatically cook the station if the pantry stays at 72. A 92-degree pantry on a milder day will. Put a cheap sensor on the wall we can photograph. If it reads above the milk spec, facilities owns the first fix, not a larger cold-brew order.

Medical Center floors with 24-hour HVAC behave differently from a downtown HQ that setbacks at 2 p.m. Tell us which you are.

Do not add more cold brew until the room is honest

More product in a hot box is more waste. Move the keg to a colder wall, crack the pantry door on setback days, or ask building engineering for a minimum airflow. Our weekly visit can rotate product. It cannot invent air conditioning.

Use the two-week trial FAQ and log pantry temperature next to cup counts. The break room readiness quiz is a useful score if facilities already knows the kitchen is the hottest room.

Milk dating gets stricter in a warm pantry

Opened cartons die faster. Name the person who dumps on a set weekday. Guest cups on a Fiesta week are a different problem. Heat is this one.

What we need on the call

A photo of the pantry, whether the HVAC setbacks after lunch, and yesterday’s afternoon temperature if you have it. Mention downtown versus Stone Oak if the account spans both.
