Phin filter brewed coffee is more concentrated due to the water to coffee ratio. Additionally, phin filters don’t require a paper filter, so the extraction process and final cup differ from pour over.

Our pricing is derived from a variety of factors such as fair labor wages, costs of materials, and production. Our producers are a small, woman-owned team in Vietnam who make our phin filters in batches. Phins at supermarkets may have been mass produced in factories without any information provided on origin or sourcing. We’re striving to be as transparent and ethical as possible through every level of our business, and the prices are an effort to reflect that.

Factors including how you’re grinding, what’s your grind size is, and whether or not you have dialed in the grind size to the phin filter affect total brew time.

For Nguyen Coffee Supply phin filters, we recommend a fine grind size and a 2:1 ratio of water to coffee. For other phin filters, we recommend experimenting to dial in according to that specific filter.

For example, coffee that is too coarse will drip too fast. Using less than 2 tbsp of coffee in a 4 oz phin filter may result in a fast drip as well.
