Japanese coffee equipment company Cafec has added a new layer of subtlety to home brewing coffee with a line of paper, cone-shaped coffee filters designed to take advantage of particular roasts. The line of filters allows the serious coffee drinker to perfect their home brew further.
Called Cafec Osmotic Flow, the filters come in three types. One each for light, medium-dark and dark roast coffees.
The magic comes from Cafec’s proprietary drying process that uses hot air and results in what Cafec calls “creping.” This is a crepe paper like texturing on their paper filters, each side of the cone, instead of just on one side. Each filter in the line takes a different approach to the dual sided texturing that allows different mesh densities and thicknesses which changes the water flow and extraction from the ground coffee.
The light roast paper filters is the thinnest but the most dense at 0.15mm. This allows the fines to gather evenly along the walls. This slows down the flow and encourages aroma while brewing. The density retains fines for better cup clarity.
The thickest paper is for medium-dark filters that are creped on each side. The paper is 0.28 mm thick but lower density. This gives the paper a faster flow that is supposed to promote balance.
The darkest roast paper filters come in at 0.22 mm thickness and are creped on each side. The interior crepe allows for faster liquid flow in the beginning and then accumulates fines towards the end. This slows the flow at the tail end in order to promote body and sweetness.
Cafec’s line includes a selection of drippers each intended to be paired with a custom filter. Cafec’s cone filters fit the ceramic Flower Dripper which has a petal shaped interior that promotes flow.
Bon Appetit has some tips for making a better cup of coffee. These are for regular brewed coffee and not cold brew.
Pre-warm your mug. If you pour your just-right temperature coffee into a cold mug, you’ve blown it. Make a little extra hot water and (especially if you do it pour-over method) and pour some into your cup. They say you will keep the temperature and flavor longer.
Don’t boil the water for your coffee. They say the optimum temperature is 200 degrees. If you boil your water for pour over, let it cool down a little.
Use your beans up. Don’t let them sit around for special occasions. This is also assuming you are buying whole beans. The further out the beans are from the date they are roasted, the weaker the flavor is.
Use the Golden Ratio. They say the ratio is 1:16 as a general rule, or 22 grams coffee to 352 grams water or about 3 tablespoons for every 12 ounces water. The ratio can be played with to your liking, depending on how strong you want your coffee.
Wet your filter ahead of time. If you are making your coffee pour over or drip, wet the coffee filter before putting ground beans in. Using some water first will help remove any flavors in the filter and hold tighter to the machine.
The GINA smart coffee instrument by Goat Story is now on kickstarter. As of today there are 45 more days to back it. So what makes this one different? The Victor crew will give a synopsis:
First of all, this instrument has a built-in scale and an app. It will also brew coffee as pour-over, immersion, or cold drip. WHAT?! The only thing it doesn’t do is grind.
So there is a Bluetooth scale that will show amounts on the app on your phone so you can make sure you have the right ratio of water to coffee. You can save your data and even share it. There is a valve that allows you to choose which brewing technique you prefer: open it for pour-over, close it for immersion, or set the drop flow for cold drip. Note: Cold brew will still take 8 1/2 hours to make. One drawback is it will only make 10 oz. using any method. They claim it would destabilize the construction. They recommend you make it stronger and add more water after you pour it.
If you were early, you could have gotten Gina for $145; there are 7 left for $160; you can pledge $175, $200 (you’ll also get a mug and specialty beans), $290 (2 Gina coffee makers), $540 (4 Gina coffee makers), $550 (one gold-plated Gina), or $990 (9 Gina coffee makers). You can also just pledge $25 for a Gina mug.
Yes, it’s finally happened. There is now an iPhone connected coffee maker. You can schedule the Poppy Pour-Over to brew your coffee from the Wink app. Even order refills of beans, water filters and coffee filters delivered by Amazon when the machine detects you’re running low.
It has a burr grinder to grind the beans. It has a glass double-walled carafe. You can adjust temperature, grind size, and brew time. It makes 10-oz or 20-oz servings.
