Eyes and Old Men

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. 😃

# Number of Boils?

This is also related to the *number of boils" which contrary to the name has nothing to do with the number of boils the water has gone through. It actually has to do with how high the temperature of the water reached. So if you know of this method then a rough translation between these two ways of determing the best temperatures and what to expect from different temperatures of tea are:

  • First Boil: Pre-shrimp eyes
  • Second Boil: Shrimp eyes
  • Third Boil: Fish eyes
  • Fourth Boil: Old mans water - this is when its been over-boiled and its generally not recommended at this point.
