Of the bioethanol places that I've tested so far for my stove, the ethanol from Richter Chemie is so far the best. Combustion will evolve very beautiful yellow flame (which was not the case with every make, I've tested so far) and that you still have the typical ethanol odor but it is significantly weaker than in the brands previously used.
Only the handling of the canister is not easy, but it should be clear for 10l canisters from the outset. Therefore, for the handling of my no penalty.
PS: Who has an ethanol fireplace, maybe you should read my recession over the Jockel household grease fire extinguisher.
