What is Burbujito and how does it work?
Burbujito is Congas' soda maker, manufactured entirely from 304 stainless steel with a stainless steel needle for greater hygiene, precision, and durability. It operates completely manually, without plugs or cables: install a standard screw-in CO2 cylinder, connect the bottle with cold water, and press the top button 1 to 3 times to achieve your preferred level of carbonation.

Includes 2 reusable 1-liter bottles (valued at €40). Food certifications LFGB, FDA, and ISO9001.

Can I cancel the Soda Club at any time?
Yes, without commitment or penalties. You can unsubscribe from your account or by writing to us at contacto@congas.es.
You will only have to pay for the return of any cylinders you have at your disposal at that time, which will cost 10 euros.
Shipping & Returns
Where do you ship to?
We ship to all of Spain, excluding the Canary Islands, Balearic Islands, Ceuta, and Melilla.
How do I return empty cylinders?
Each order includes a return box. Place the empty cylinders inside and hand them to the courier on your next pickup. Zero waste, zero hassle.
Sustainability
Is it really more sustainable than buying bottled sparkling water?
Yes. Each reusable cylinder replaces up to 120 plastic or glass 500ml bottles. We also work with carbon-efficient couriers, use durable stainless steel, and operate in a closed loop without unnecessary packaging.
