Field Review

One of the enduring attractions of bioethanol cooking is its elegant simplicity. There are no moving parts, no pressurised fuel canisters and very little that can fail. The Vesuv Hotspot 40 embraces that philosophy whilst introducing an important refinement that immediately distinguishes it from many traditional alcohol burners.

At the heart of the burner is its carbon felt absorbent core. Rather than allowing fuel to remain free inside the stove, the carbon felt absorbs and securely retains the alcohol, significantly improving safety. When filled to the recommended maximum capacity, the stove is effectively non-spill. Should it be accidentally knocked over before or during use, the fuel remains held within the carbon felt rather than immediately flowing across the ground. It's an elegantly simple solution that provides genuine reassurance when cooking in the outdoors.

The carbon felt also contributes to the stove's excellent performance. During our testing, the Hotspot 40 consistently bloomed quickly and produced a stable, even flame that remained remarkably consistent throughout the burn.

The additional 40ml fuel capacity makes the Hotspot 40 particularly well suited to larger cookware and longer cooking sessions. We found it pairs beautifully with the Evernew Titanium UL Pot 0.9L and equally well with the Evernew Titanium Pasta Pot 1.3L, providing ample burn time for boiling water, preparing dehydrated meals and simple backcountry cooking.

As with the Hotspot 30, we often recommend using less fuel whenever full burner output isn't required. A reduced fuel volume naturally creates a slightly smaller flame diameter, making simmering easier whilst also reducing overall fuel consumption. It's a simple technique that adds another level of versatility to an already highly efficient burner.

Reliability is another quality we particularly appreciate. There is virtually nothing to maintain, adjust or service. Simply add fuel, light the burner and cook. That uncomplicated dependability is one of the reasons bioethanol stoves continue to be trusted by experienced backpackers around the world.

The Hotspot 40 also integrates beautifully with the Vesuv Outdoors Titanium Windscreen, which has been purpose-designed around the burner and complementary cookware. Together they create an elegant cooking setup that provides excellent wind protection whilst maintaining exceptional packability and fuel efficiency.

Throughout our testing, what impressed us most wasn't simply the stove itself, but how naturally it integrates into a thoughtfully considered cooking system. Every component complements the next, resulting in a cooking experience that feels intuitive, dependable and quietly satisfying to use.

Who is it for?

The Vesuv Hotspot 40 is ideally suited to backpackers, wild campers and mountain enthusiasts seeking a lightweight, dependable and beautifully simple bioethanol cooking solution.

It is particularly well suited to those using larger titanium cookware, preparing meals for two people or simply wanting the reassurance of a little additional fuel capacity whilst retaining an exceptionally compact cooking setup.

Those pursuing the lightest possible solo cooking system may prefer the smaller Vesuv Hotspot 30.

Things to Consider

• Bioethanol stoves naturally require a little more patience than many gas stoves, particularly in colder conditions.
• Best performance is achieved when paired with an appropriately designed windscreen.
• Fuel efficiency will vary depending on cookware, weather conditions and the amount of fuel used.
• For improved simmer control, we recommend using a smaller quantity of fuel, naturally producing a smaller flame diameter.
