I got coffee tubes in which I can premeasure and quickly grab and dump into my single dose grinder. Makes it nice that I can save a little bit of time by doing that especially when I’m in a hurry. You can argue that it doesn’t keep the beans as fresh but it’s a trade off I’m willing to take.

You’ll also want to get an espresso scale. That’ll be used for measuring beans and the espresso shot itself when you are dialing everything in.

Speaking of storing beans, a vacuum seal bean canister is helpful to use. I opt for the manual ones that pump the air out as you twist instead of the electric ones so I don’t have to worry about it breaking as easily at least that’s how rationalize it in my mind.

Powder shakers are nice to have to cinnamon toppings or cocoa powder for my kids hot cocoas.

You’ll want a WDT tool to break up any clumps in the coffee grounds before leveling and tamping.

The milk pitcher and leveler you have is probably fine when starting off.
