A flask is a simple yet indispensable accessory for professional hot beverage service. Vacuum insulation between two layers of stainless steel reduces heat loss, keeping beverages at an optimal temperature for hours. Professional flasks differ from household models with their larger capacity, more durable stainless steel body and ergonomic opening mechanism designed for intensive daily use. BHS offers a wide range of professional flasks for HoReCa businesses across Europe.
Types and capacities of flasks
Professional flasks are available in various capacities to suit different applications. Smaller models of 0.5–1 litre are ideal for table service, pouring individual portions for guests. Medium flasks of 1.5–3 litres are used to store and serve a single coffee machine jug or a batch of tea in a café. Large flasks of 5–10 litres are designed for hotel breakfast areas, conference coffee breaks and banquet service. Also available are Thermos Flasks with Tap for easier large-volume serving without spills. The choice of flask capacity depends on the number of portions served and the intensity of customer flow.
Heat retention and hygiene
High-quality professional flasks keep hot beverages at 85°C–95°C for 4–6 hours, after which the temperature gradually decreases. Important: preheat the flask with hot water before use to significantly extend heat retention time. In the HACCP context, the temperature of beverages in the flask must be monitored – coffee and tea below 60°C are not recommended for prolonged storage. Regular cleaning and disinfection of the flask after each use is a mandatory hygiene requirement. The BHS range includes flasks with easily replaceable and washable internal components.
HoReCa usage scenarios
In hotel breakfast areas, flasks with coffee and tea are a standard buffet element, providing guests with convenient self-service without staff involvement. In cafés, flasks are used to store prepared coffee and tea between orders, ensuring faster service. For conference centres, flasks are a more efficient solution for organising coffee breaks than small coffee machines. In catering, flasks are the main tool for serving hot beverages without an electrical connection. For banquet service, flasks with coffee and tea enable efficient service for large groups. BHS helps select the most suitable flask models, capacities and configurations based on the business’s service specifics and daily customer flow.
Frequently asked questions
How long does a flask keep coffee warm? A high-quality professional flask keeps coffee above 80°C for approximately 4–6 hours. After 8–10 hours, the temperature is usually 60–70°C, which is still acceptable for serving coffee. The heat retention time can be significantly extended by preheating the flask interior with hot water for 2–3 minutes before pouring in coffee or tea.
How to clean a flask properly? After each use, wash the flask with warm water and a mild detergent, thoroughly rinsing all parts. Special flask cleaning tablets can be used regularly to remove coffee and tea residues. Do not use abrasive cleaners or scouring pads, as they scratch the inner stainless steel surface and impair heat retention.
