I’ve found the link is mostly CO2 + surface oils: lighter roasts can show thin crema unless you give them a gentle 8–10s preinfusion at about 2–3 bar, then ramp up — like inflating a balloon slowly so it doesn’t tear… @claire_h92, have you tried a paper puck screen to keep the crema pretty but the cup cleaner? For darker roasts, drop brew temp 1–2°C to keep that big crema from tasting ashy.
I get fuller, more stable crema on light roasts by bumping brew temp 2–3°C and adding a paper puck screen under the basket. Building on @michaelv93, hold a slow about 3–4 ml/s preinfusion until first drops before ramping; if your water’s very soft, that combo really helps. Small caveat: ultra-soft water (<40 ppm alkalinity) can make crema collapse, so SCA‑ish water helps (https://www.baristahustle.com/blog/a-recipe-for-water/), and remember crema’s more lipstick than flavor.
If your crema’s thin on light roasts, increase headspace — drop the dose 1–2 g in the same basket and cut the shot a beat before blonding. Building on @michaelv93, this gave me a denser, longer‑lasting cap on our Linea PB with no extra gear; just note you may need a touch tighter grind to keep flow in check. Since last week’s talk on “everyday” sustainability, I like this as a zero‑cost tweak — what basket are you on, stock or high‑flow?
Different angle: if your water’s ultra‑soft, the cap collapses fast — aim for about 40 ppm alkalinity and about 70–90 ppm hardness with some Mg, and the top sticks around like it means it. @jonesy54, have you noticed this when swapping waters?
One lever that’s been huge for me is rest time by roast: lighter roasts often hit a stable head around days 10–14, while darker roasts peak closer to days 3–7; too fresh and you get big bubbles that disappear fast. Quick step: pull the same coffee on days 3, 7, and 12 and note head height vs flavor. @michaelv93 have you A/B’d rest windows, and this piece sums it up nicely: https://www.baristahustle.com/blog/how-fresh-is-too-fresh/.
