My starter brewing kit came with 100g of Sodium Metabisulphite for sanitation. It advises to dissolve 1 tsp per pint of water. However there are no futher instructions.
I don't know how long I need to leave it in contact with my equipment and whether I need to rinse everything thoroughly with water after contact with the sodium metabisulphite solution.
I need to sanitise a 23 litre fermenting bucket and around 50 glass bottles, so is it best to make up a full 23 litres of sanitising solution and fill the bucket entirely, or can I just sloosh a smaller amount around in my bucket?
