Beverage thermoses and percolators are a crucial element of professional service — they allow hot tea or coffee to be kept warm for extended periods without the need for reheating. This is particularly important in buffet service, conferences and events where beverages must be offered to a large number of guests simultaneously. In the HoReCa sector, a professional thermos and percolator system is a daily service necessity.
How beverage thermoses work
Professional beverage thermoses operate on the principle of double-wall insulation — a vacuum or special thermal insulation material is created between two metal or glass walls, minimising heat exchange with the surrounding environment. A high-quality stainless steel thermos can maintain the beverage temperature within +60–+80°C for 6–12 hours, depending on capacity and insulation quality.
Percolators differ from thermoses by having a built-in tap for dispensing — making it easier to serve beverages to a large number of guests without holding a heavy container. Some models are equipped with a heating element to maintain a constant temperature. Modern thermos designs include a hermetically sealed lid, which prevents temperature loss from the outside and facilitates transportation.
Applications of beverage thermoses
In buffet service, a set of thermoses with separate compartments for tea and coffee is a standard solution for conferences, breakfasts and events. In cafés, small thermoses or thermal carafes can be placed on guest tables, allowing customers to help themselves to additional beverages. In restaurants, a tea service with a thermos ensures that guests always have hot tea without the need for additional service.
In catering businesses, a thermos system is the primary solution for transporting hot beverages to event locations outside a stationary kitchen. In hotels, rows of buffet thermoses with different types of tea and coffee are a common element of a welcoming breakfast service.
HACCP and hygiene requirements
Beverage thermoses and percolators must be washed and disinfected after each use. The stainless steel interior should be cleaned with special detergents to remove limescale and greasy deposits from the glass or metal surface. Regular descaling prolongs the equipment’s service life and ensures the purity of the beverage’s flavour.
Thermos lids, taps and other removable parts should be disassembled during cleaning to ensure no product residue remains at the joints. To maintain hygiene, it is recommended to follow the manufacturer’s cleaning protocol, which typically includes rinsing with cold water immediately after use and hot washing after the work shift.
HoReCa usage scenarios
In a café’s buffet area, a large stainless steel thermos with a tap for tea and a percolator for coffee provide accessibility for a large number of guests independently. During conference and seminar breaks, a thermos system with hot beverages and frequent availability is an indispensable part of the service. In hotel breakfasts, multiple thermoses with different beverages along the buffet area meet guests’ needs without direct staff involvement in serving each drink.

Frequently asked questions
How long does a thermos keep a beverage hot? A professional stainless steel thermos with vacuum insulation keeps a beverage hot for 6–12 hours — depending on capacity, how often the lid is opened and the initial beverage temperature. Larger thermoses often retain heat longer, as they have less surface area relative to volume.
What is the difference between a thermos and a percolator? A thermos is a hermetically sealed container with a lid that must be tilted for pouring. A percolator is equipped with a built-in tap for convenient dispensing without lifting the container — ideal for buffet service and situations where quick and easy beverage dispensing is needed for many guests.
