What is a bar in pressure?
The bar is a metric unit of pressure, but not part of the International System of Units (SI). It is defined as exactly equal to 100,000 Pa (100 kPa) , or slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar).
How do I lower my espresso pressure?
- Use Coarser Ground Coffee. The first thing you should try to decrease the pressure in your espresso machine is to use coarser ground coffee
