Eyes and Old Men

Boiling Water

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. :)
