A traditional Vietnamese brew tool, our Original 4 oz Phin Filter makes a perfect single serving of highly caffeinated brew. Great for reducing coffee waste. We recommend a 1:2 ratio of coffee to water. So start with 2 tablespoons of coffee, then you can add or decrease your coffee depending on how strong you like it. Super versatile! With the 4 oz Phin, we recommend doing a second pour of hot water since some of the water always gets absorbed by the coffee. This Vietnamese brew tool is perfect for your daily grind. - No paper filter - it's sustainable! - Stainless steel - 4 oz chamber with 3.25 inch plate diameter - Great for traveling - Perfect brew in 5 minutes Buy one for the price of 3 lattes and use it everyday.
