Portafilter filter basket open basket double shot

🧺 Espresso Basket, open choice, essential for making a professional espresso shot because it allows full control over grinding, distribution, dose, and tamping, and shows the true flavor of the coffee without "artificial assistance" in the crema. Available sizes: 51 mm basket | 58 mm basket. Suitable for regular portafilter as well as bottomless baskets. ☕ Preparation of single shot (non-tamped). Coffee dose: 10–12 g usually (note: 30g doses are used for special recipes/heavy ristretto and are not standard for most single baskets). Extraction pressure: ~9–10 bar (most machines are calibrated at 9 bar, and 15 bar is the maximum pump capacity, not the ideal extraction pressure). Target time: 20–30 seconds depending on the recipe. Usual yield: 25–35 ml (depends on your style: ristretto/normal/long). ☕ Preparation of double shot — the most commonly used standard. Coffee dose: 17–18 g (very common in 58 mm baskets). Target time: ~28 seconds. Yield: ~60 ml (or approximately 1:2 extraction ratio). Suitable for: pure espresso and milk-based drinks. 🧺 What is a pressed basket? A pressed espresso basket has a small hole/valve that creates pressure before the coffee exits, giving crema even if the grind is coarse or not ideal. When is it useful? For beginners or when using pre-ground coffee. When do we not prefer it? When you want a professional taste and full control — choose the non-pressed basket. 🎯 How to choose the size? If your machine is home-use with a small set: mostly 51 mm basket. If professional/semi-professional: mostly 58 mm basket. Breville machines are usually 53 mm. For advanced baristas, training, and extraction experiments: use a bottomless basket to monitor flow and avoid channeling. ✅ Quick summary: Non-pressed coffee basket = better taste and control. Pressed espresso basket = practical solution for beginners and "ready" crema. Common sizes: 51 mm basket and 58 mm basket. For the professional barista: bottomless basket + fine grind + good distribution + consistent tamping = perfect shot.
