What is the difference between square and circle Chemex filters?
The square and circles are functionally the same. The points of the squares protrude a bit from the top of the brewer, making it easier to remove the filter. Filters out fine sediment and oils so the final brew is clear and flavorful. The Chemex brewing system has been around since 1941. What brew ratios should you use for a Chemex? Golden Cup Standard: The Golden Cup Standard is an excellent baseline for any brewing method, including pour-overs. The standard recommends a coffee-to-water ratio of 1:17 to 1:18, meaning you would use 17 grams of water for every 1 gram of coffee grounds.Size: The Chemex comes in bigger sizes, which is great for brewing lots of coffee at one time. The V60 is more convenient when you just want to brew a cup or two. Filter papers: The Chemex uses thicker filter papers, which remove the oils and make for a clean, juicy, light-bodied brew.Conclusion. To sum it all up, the Chemex is a well-known pour over coffee making method. Compared to other pour over brewers, the Chemex stands out due to its beautiful glass body, flexibility in size, and thicker filters which result in a unique brew with a hint of sweetness.A Good Ratio for the Chemex is 1:16. While this general range of 1:16 to 1:18 will produce decent brews across most of the brewing spectrum, each particular brew method calls for a more specific ratio within this range.
