Coffee, to brew or not to brew

It really is possible to make coffee using cold water, Terzi insists. Cold percolated coffee takes an entire night to brew, but is supposed to be easier on the stomach.

Like many others, the E61 is spring-operated. This means the coffee is brewed at a controlled but variable pressure: initially high, when the barista pulls the lever to compress the spring, gradually declining as the spring releases. Controlling the pressure is key to creating a good espresso.

The general assumption is that a small cup of espresso is stronger than a long coffee – but that isn’t necessarily the case. “Caffeine can melt very easily in the water, so in the first five or 10 seconds you extract all the caffeine from the coffee,” Terzi explains.

 

But a short coffee is more easily digested than a longer one, because in the beginning you extract only the good substances from the coffee.” After that, he says, if the coffee keeps on brewing, it starts to release other elements as well which are not so desirable.

I brew mine quick then stir and let set all day in grinds using a mesh strainer to pour each cup – this way I get 3 cups of  flavorful strong iced coffee and brew only once.

Happy brewing!

All the world’s gold came from collisions of dead stars, scientists say

 

Researchers have new evidence that gold comes from the collision of neutron stars.

 

“We can account for all the gold in the universe from these collisions,” said Edo Berger, astronomer at the Harvard-Smithson Center for Astrophysics. Berger spoke about these results, submitted for publication in The Astrophysical Journal Letters, at a press conference Wednesday.

“Smash two of them together at close to the speed of light and you can expect fireworks,” Woosley said.

“The gold and platinum in our rings as well as the uranium in our bombs and reactors are little pieces of neutron stars that merged in our galaxy long before the sun was born,” Woosley said.

This same gold from space became part of the formation of Earth and the rest of the solar system, including the sun.

 

Gold that was present in the Earth’s formation sank to its core. But we have gold that can be mined closer to the planet’s surface because meteorites brought it later, according to a 2011 study in the journal Nature. More than 200 million years after the planet was formed, a shower of meteorites hit and brought with them gold, which stayed in the planet’s mantle.
