What is a good espresso machine for home use?

Expert reviewers say this is the best espresso machine for serious coffee aficionados. The Rancilio Silvia gets high marks for its espresso taste, features, ease of use and build quality. The stainless-steel Silvia has a forged-brass boiler for durability and to better retain heat. Some users say the Silvia is sensitive to grind coarseness -- meaning that coffee beans need to be finely ground and tamped properly -- but the machine is compatible with packaged coffee pods as well. A separate pod adaptor kit (*Est. $90) is required, however. Frothing milk properly also takes practice, but experts say that the Silvia lives up to its reputation as best in this price class.


Why is it good to avoid the first 1-2 cups from an espresso machine?

Commercial espresso machines have a large boiler half-filled with hot water (and half-filled with steam). This is not the water you use to make espresso. Instead, water for the coffee is pumped (cold) into a small chamber called a 'heat exchanger'. This heat exchanger uses the heat from the boiler to flash-heat the cold water. This freshly-heated water is used to make your coffee. It's good to avoid the first 1-2 cups from an espresso machine because the water that comes out for those first coffees has probably been sitting in the heat exchanger, being hot, for a long time. Water that's been hot for a while loses it's dissolved oxygen and has a 'flat' taste that most folks don't like. Barista Tip: Run each group for 1-2 minutes in the morning before making coffee, to flush the heat exchangers. Your customers will thank you.

Can you use a boiler drain valve on a washing machine?

Yes, you can use a boiler drain valve for a washing machine, but it's not the most common choice. Boiler drain valves are designed to release water from heating systems and may not be as efficient for washing machines, which typically use standard hose connections. Ensure the valve is compatible with the washing machine's water supply requirements and that it can handle the pressure and flow rates involved. It's advisable to consult a plumber or the manufacturer's guidelines for the best fittings.
