I like the matcha Starbucks uses. Problem is the sugar’s mixed in and you can’t adjust it. All pre-sweetened. I would prefer unsweetened and adding my own honey or agave.
Get the Sencha Matcha from Amazon (LINK). Outstanding quality and reliability, and by far the best price per ounce for the quality. My entire family uses it, with raw milk or almond milk, honey or maple syrup or agave, and one of those handheld whisk things from Ikea.
