Eyes and Old Men
December 31st, 2008
If you’ve never heard of the terms: “Fish Eyes” and “Old Mans Water” then may I enlighten you to an ingenious way of determining the temperature of your boiling water.
Shrimp Eyes – This is in reference to the size of the bubbles in the water. If they’re small – like that of a shrimps eye balls – then you’re at a temperature of 60-70C.
Fish Eyes – Bigger bubbles like fish eyes are a sign of 75-85C.
Old Mans Water – This is when the water has lost all its oxygen and ‘rolls’ in the kettle. When you get this you’ve hit 100C.
For the vast majority of uses fish eyes is the best to brew with.
