Our vacuum jugs and pump flasks are great when you are dining outdoors, having a picnic or when you are a large crowd at the dinner table. Brew tea or coffee and simply pour it into a vacuum jug and it will stay warm for a few hours and it also looks good! If you are a big gathering then a pump flask is very handy. It has a generous capacity and is easy to serve from. Great for the buffet table or large family dinners. If you use your vacuum flask for coffee, and then if you use it for tea, it won't taste great. Therefore, we recommend you use a separate jug for coffee and a separate one for hot water or tea.
