Linea Caffe's espresso parameters for A4: 19 g in a double basket for a ristretto-style 24–25 g out in 24 seconds.

Linea state the temperature as 199.7–200.1 °F (93.2–93.4 °C) and the yield as a window; both are recorded as stated. Their instruction with the yield: "Going ristretto style is important. Not super ristretto – but very ristretto compared to current norms." Linea's own brew-guides page states different espresso parameters for A4 (200.4–201 °F, 24–26 g yield, 24–26 s); neither surface is authoritative on this domain, and this document carries the product page's block.
