Here it was about 50g coffee and 100g milk but you can adjust it to your taste

A bit coarser then espresso grind but finer then for filter. I am using medium heat.

Everything in this video is only about $800~850 but you could easily use more affordable tools, scales are $20 bucks, mokapots $30 bucks, the grinder they use is expensive $650 but you don't need that high end of a grinder (the fellow opus is $200 bucks and is great) the nanofoamer is very high end as well $150 (but you could easily microwave/or stovetop your milk and use a $10 frother), Milk pitcher $10 bucks.

You are right. I was a bit lasy to take out my all purpose grinder (100€) that also works find for this purpose. I might make another video with that grinder. And maybe find a cheaper metod for milkfroth as well. This was just an idea I got with the stuff I had on the counter. But well observed 👍
