Open kitchen shelving - to or not to do?

I vote no. A think film of grease seems to find its way everywhere in a kitchen. Enclosed cupboards will protect the contents.

Open shelving is high maintenance. Looks great but keeping it looking great requires consistent and constant cleaning and dusting. It comes down to how much time and effort you want to invest in this maintenance.

If you really want open shelving, keep the number of items to a minimum and don't crowd. Less things, less work in cleaning it. It will also keep a neat appearance. For small items, put them in a basket/bin or tray that you can easily pick up/pull out. It helps with cleaning, a lot.

There's a mix of open and closed cabinets in my kitchen—and I totally love the open shelves. They're super practical for cooking and baking. They also feel like an easy way to "decorate" a space, since what's on display on the shelves (e.g., plates, bowls, mugs) instantly becomes the kitchen's distinguishing features.

I know there are arguments both for and against. Can't tell which you and your household will eventually prefer.
But you can protect yourself against buyer's regret by designing the open shelves (if you decide for them) so doors can easily be added.
Or, vice versa, leave one set of cupboards with doors unhung, in storage.
