Whole Bean or Pre-Ground Coffee for Espresso? Start Here

One rule decides it: whole bean if you own an espresso-capable grinder, pre-ground if you want the fewest steps. The full answer is in the Home espresso setup guide under "Do I need a grinder?"; the short version is here.
Whole bean, if you can grind for espresso
Espresso needs a much finer, narrower grind range than drip coffee, and grinding your own buys you the fix: a shot that runs too fast or too slow is corrected with a grind change, and a drip grinder cannot make it. Grind close to brewing and keep the bag sealed away from heat and light.
Baratza Encore ESP. Settings 1 to 20 cover espresso and 21 to 40 cover filter coffee, so one grinder serves a shot and a pot. The 54 mm dosing cup matches the Bambino, a 58 mm adapter is in the box, and a 51 mm machine works with the cup held under the chute. Quiet enough for an early house. The catch: more grinder than a drip-only kitchen needs. Our note

Pre-ground, if you want the fewest steps
Pre-ground is not a beginner mistake. Buy coffee sold for espresso or a fine grind, and accept that you cannot make small adjustments when a shot tastes sour or bitter. A pressurized basket makes a fair shot from it, and both machines we list ship with one.
- Breville Bambino, 54 mm. Pressurized and non-pressurized baskets in the box: start on pre-ground, switch baskets when the grinder arrives. The catch: accessories are Breville 54 mm, not the common 58 mm. Our note
- CASABREWS CM5418, 51 mm. One-cup and two-cup pressurized baskets in the box, so pre-ground works from day one. The catch: 51 mm is the odd accessory size; search by model name, never "universal". Our note
The quick check
- Have an adjustable espresso grinder? Whole bean.
- Want the fewest steps? Pre-ground, sold for espresso or a fine grind.
- Machine ships with a pressurized basket? Pre-ground works on day one.
- Moving to a non-pressurized basket? Whole bean, grinder first.
Either way, the first bag
Buy a small bag you can finish while it still tastes good, pick tasting notes you already like, and change one thing at a time when you dial in: grind, dose, yield or time.
