The La Marzocco Linea Mini delivers commercial-level stability in a home format, offering precise temperature control and consistent pressure. With Gruetini, this allows for a structured, syrupy espresso that balances sweetness, depth, and clarity.
Gruetini is designed to perform as a refined espresso: dense crema, integrated acidity, and a smooth, rounded finish that carries through beautifully on its own or in milk.

Step-by-Step Method
1. Preheat & Prepare
Turn on the Linea Mini at least 20–30 minutes before brewing to ensure full thermal stability.
Lock in the portafilter during warm-up so it reaches proper temperature.
Purge the group head briefly before inserting the portafilter.
2. Dose & Distribute
Grind 18g of Gruetini to a fine espresso consistency.
Distribute evenly and tamp with firm, level pressure. Consistency here directly affects balance and extraction.
3. Extraction
Insert the portafilter and begin extraction immediately.
Aim for:
-
First drops at 6–8 seconds
-
Full extraction at 25–30 seconds
-
36–40g final yield
The espresso should flow like warm honey — steady and cohesive.
In the Cup

-
Structured sweetness
-
Balanced intensity

-
Velvety mouthfeel
-
Long, refined finish
The Linea Mini’s temperature stability ensures sweetness remains pronounced while preventing harshness or over-extraction.
Dialing In
If the shot tastes sharp or underdeveloped:
Grind finer or increase yield slightly.
If the shot tastes bitter or heavy:
Grind coarser or reduce yield.
If sweetness feels muted:
Raise brew temperature by 0.5–1°C.
If acidity dominates in milk drinks:
Pull slightly shorter (closer to 1:2 ratio).
