KOHIRO.
Step-by-step pour over guide.
Follow a glass V60 from the first rinse to the last drop, with a timer and a water-weight target for every pour.
From kettle to cup.
Watch each stage.
Glass brewing equipment rendered in Blender shows when to heat, rinse, dose, bloom, pour and let the water drain, under a Liquid Glass interface.
Pour to the target.
The timer follows the recipe. Read the water weight for the next pour and watch your scale as you go.
