Would you believe someone have improved out trusty friend the airlock.
Now I may be out of date here - 'cos I make red wine and thus have not used air locks for years.
Having just purchased three new airlocks for a batch of white, I was pleased to see they have a reference fill level. They are the cylinder type, but the lid (bright orange) does not clip on. When the yeast started I became aware of this tapping noise - yes you guessed it the lids pop up and down with each bubble. It is now very obvious which barrels are working and which not and how fast.
A bit like the whacka mole game
