Is it better to infuse spices whole or ground?

Expanded Explanation

Whole spices are usually better for liqueur infusions because they extract more slowly and cleanly. They give the maker more time to control flavor development, and they are easier to remove when the desired intensity is reached. Whole cinnamon, cardamom pods, star anise, and peppercorns often produce clearer, more refined results.

Ground spices extract very quickly because they expose much more surface area to alcohol. This can be useful for fast experiments, but it increases the risk of bitterness, harshness, sediment, and cloudiness. Ground spices can also be difficult to filter completely, leaving a dusty texture or dull appearance.

A good compromise is to lightly crack, bruise, or split whole spices rather than grinding them into powder. This opens the ingredient enough to release aroma while keeping extraction manageable. For professional-looking liqueurs, clarity and control usually matter as much as flavor intensity.
