The source attributes this V60 recipe to Josh Cook of Brew Coffee Better. It begins with 20 grams of medium-fine coffee and an overall water target of 320 grams, providing a clear one-to-sixteen starting ratio.
Rinse and warm the filter and brewer, arrange the grounds with a small depression, and bloom with 60 grams of water. Swirl to wet the coffee. At about 45 seconds, make a slow, steady circular pour until the total reaches 320 grams. The source suggests another gentle swirl near one minute fifty.
Its finishing window is roughly three minutes fifteen to three minutes thirty. Use that as a comparison point rather than a requirement to force every coffee into the same time. Record the taste and flow, then adjust the grind deliberately before redesigning the whole recipe.
