Grease and lightly flour the pan, preheat the oven (175 degrees).
Mix the flour with the baking powder, salt and sugar.
Add the beer while stirring (the dough remains viscous).
Pour the bread into the tin and bake on the middle shelf for about 60 minutes.
If the bread gets too dark before the end of baking, cover it with aluminium foil (so it continues to cook, but does not brown any more).
At the end of baking make a cooking test with the wooden skewer, if there is still dough sticking to the skewer, the bread remains in the switched off oven for another 10 minutes.
If no dough sticks to the skewer, the bread is taken out of the tin and placed on a cake rack to cool down.
