Espresso is a really big and fun world. We definitely recommend scales, a grinder and timers for consistency and improved quality. If you are confident with a scoop and are happy for some leeway, follow the advice in this video. This guide is for making an 18g espresso or flat white.
For best results, use freshly ground coffee from a good quality grinder. Store the coffee in a cool place, and use filtered water wherever you can. Also, keep everything really clean – it makes your espresso taste way better – trust us. Clean your steam wand, flush your machine wherever you can, wash the handles with soapy water with the basket taken out – and your coffees will taste delicious all the time.
