Expert Review and  Insights

The Stelton jug is one of those rare items that genuinely excites people in the industry. It's a design classic, but it's the performance that makes it a professional staple. The choice of a glass liner is key—it’s a nod to quality and  flavour purity that many modern all-steel flasks miss. It tells you this was made for people who truly appreciate a good brew.

Emily Hart – Tableware Expert View Profile →

  • Best for Flavour: The glass inner means coffee tastes purely of coffee, not metal.
  • Handle with Care: The glass liner requires gentle handwashing; it's not for slamming around.

Case Study: Real Business, Real Results

'The Hepworth Gallery Kitchen' in Wakefield decided to upgrade their tabletop coffee service to better reflect the artistic and  modern environment of the gallery.

"We needed something that was both incredibly functional and  aesthetically pleasing. These Stelton jugs fit the bill perfectly. Our coffee stays hot through the busiest lunch service, and  they look like they belong in the gallery itself. Customers have definitely noticed the step-up in quality."

Michael Davies – Hospitality Manager

The change resulted in a marked improvement in service efficiency and  positive mentions in customer reviews regarding the presentation of their hot beverages.

Installation and  Maintenance Guide

Setting It Up

  • Before the first use, rinse the jug and  stopper with warm, soapy water and  dry thoroughly.
  • To maximise performance, pre-heat the jug by filling it with hot water for a few minutes before adding coffee.
  • For cold drinks, pre-chill it with cold water to keep them refreshingly cool for longer.
  • Ensure the stopper is screwed on firmly to create a proper vacuum seal and  lock in the temperature.

Keeping It Going

  • This jug is strictly handwash only. Do not place it in a dishwasher, as it can damage the seal and  finish.
  • Use a soft-bristled bottle brush and  mild detergent to gently clean the delicate glass inner.
  • Never use abrasive scouring pads or harsh chemical cleaners on any part of the jug.
  • After washing, allow it to air dry completely with the stopper off to prevent any odours from building up.

Buying Guide: Choosing the Right Thermal Jug

Need help choosing? Here are a few things to think about when selecting a jug for your business.

Capacity vs. Use Case

A 1-litre jug is perfect for tables of 2-4 or small meetings. For large buffets or high-volume service, consider buying several or pairing them with larger airpots.

Inner Material Matters

Glass inners, like in this Stelton 1L thermal coffee jug, offer the purest taste. Full stainless steel flasks provide maximum durability for very rough-and-tumble environments.

Style of Service

A beautifully designed jug is ideal for table service or elegant self-serve stations where presentation is a key part of the customer experience.

Cleaning and  Upkeep

Always check the care instructions. Handwashing, while more hands-on, often preserves the seals, finish, and  overall lifespan of a premium jug.

Match Your Aesthetic

Choose a flask that complements your brand's identity. A sleek, modern jug can be a subtle but powerful part of your establishment's overall decor.

Frequently Asked Questions

Q: How long will this jug keep coffee hot?

A: It will keep beverages hot for several hours. Performance is best when the jug is pre-heated and  remains mostly full.

Q: Can I use it for soup or other liquids?

A: It's primarily designed for beverages like coffee, tea, and  water. We'd advise against thick liquids like soup, as they can be difficult to clean from the glass inner.

Q: Is the glass inner fragile?

A: The glass inner is well-protected by the steel body but can break if the jug is dropped or handled roughly. It should be treated with the same care as glassware.

Q: Is this a genuine Stelton product?

A: Yes, we are an authorised UK supplier of genuine Stelton equipment, including the DE939 designed by Erik Magnussen.

Q: Is this jug suitable for busy commercial kitchens?

A: Absolutely. It’s designed for professional settings like cafés, hotels, and  offices where both high performance and  great style are essential.

Q: What is the capacity in cups?

A: The 1-litre capacity provides approximately 6-8 standard teacups, making it ideal for small groups.

Q: Can I put it in a dishwasher?

A: No, this model is strictly handwash only to protect the vacuum seal and  the delicate glass liner.

Q: Does the top seal completely to prevent spills?

A: The stopper creates a firm seal to prevent spills during transport and  to maximise heat retention. The spout is designed for a clean pour.

The Stelton Advantage: An Investment in Taste and  Style

Choosing a Stelton product is about more than just its technical ability to keep drinks hot; it's a deliberate investment in your brand's image. This commercial insulated jug Stelton DE939, born from the mind of Danish design legend Erik Magnussen, is an internationally recognised symbol of quality. It communicates a standard of excellence to your patrons before they even pour their drink. The thoughtful engineering—a hardy stainless steel exterior protecting a flavour-preserving glass interior—is a testament to a philosophy that refuses to compromise on quality. This isn't a flask you'll replace next year; it's a durable, long-term asset that enhances your service, reduces waste through superior heat retention, and  adds a touch of timeless class to your daily operations.

Why a Glass Inner is the Pro's Choice for Flavour

Ever notice a faint, slightly metallic taste in your drink from a standard flask? That's what a glass inner liner is specifically designed to prevent. Think of it as the difference between drinking tea from a fine china cup versus a metal camping mug. Glass is completely non-reactive and  non-porous, meaning it doesn't interact with the liquid it's holding or absorb old flavours. This ensures that your carefully sourced coffee or delicate herbal tea tastes exactly as it should—pure, clean, and  untainted by its container, from the first pour to the very last drop.

Who Should Buy This?

  • Boutique Cafés: An elegant solution for serving batch-brew filter coffee or hot water for tea at the table.
  • Corporate Boardrooms: Impress clients by keeping coffee and  water perfectly tempered throughout long, important meetings.
  • Luxury B&Bs: A stylish and  professional restaurant hot drinks dispenser for a premium breakfast buffet experience.
  • Fine Dining Restaurants: Offer guests a personal pot of coffee as part of a polished after-dinner service.
