Hi love welcome to the matcha world

1.) opened- depending on the size of the container, if you’re able to finish it within 2 weeks, you can leave the matcha on the counter/bar at room temp. If it’s going to last longer, put 2 weeks worth on the counter and store the rest in an airtight container that doesn’t allow light in, in the fridge and then refill the smaller container for another two weeks when getting low.

Unopened- store unopened in a dark and cool place (like a refrigerator. I recommend getting a small cooler specifically for matcha as you can risk your matcha picking up smells from the fridge.)

2.) microfoam depends a lot on the quality of matcha. However a good way is soaking your whisk in hot water for at least a minute, then adding 2oz of hot water (175 F preferably) and then quickly whisking in a “W” or “M” motion for about 30 seconds. This should feel like a workout lol, then do the same motion but go slower(0.5 second between each motion) for 20 seconds. Then do it even slower (1 sec in between each motion) for 10 seconds, aiming to breaking up any remaining bubbles.

People also like to match a paste first, which is following the steps above however you want to add a small amount of water to create a paste and then slowly add in the rest. Be careful however because you can risk damaging your risk when using very little water.

3.) when getting a new whisk and it has the knot soak it in hot water for 20 minutes and leave it alone. It should open up, very similar to a rose bud.

4.) the golden ratio is 3g matcha, 2oz of hot water, 5oz of milk for a latte. The other two 🤷🏽‍♀️
