Atmos is incredibly simple to use. Just fill, tamp and flip.
Here are a few things you should know before you start, and more info to explore when you're perfecting your own style.
Before You Start
Setup on a level, waterproof surface such as your kitchen benchtop to minimise the risk of stains and spills. Give everything a thorough rinse to ensure it is clean for your first brew
Your coffee grinds are the most important ingredient: Freshly roasted and ground beans will give the best flavour, but to begin, your favourite "espresso grind" coffee will work.
The finer your grind is, the slower your extraction will be.
This simplest part of making coffee, although your water source and temperature are important factors in perfecting your process.
How long your brew takes will depend mostly on the grind and amount of coffee. We recomend 6 - 10 hours, but your first brew might be quicker or slower.
1 - Fill
Fill the basket with coffee grounds using MIN-MAX indicators as a guide . For best results, use fresh espresso ground coffee. Fill one of the bottles with water.
We recommend filling to the MIN. side of the scale (loose, uncompacted grind) until you get a feel for how fast your particular grind is. Aim for about 6 hours to start, then adjust the amount of coffee to make it faster or slower.
Don't forget to write the amount and type of coffee on your brew card. The more details you record, the better.
2 - Tamp
Wipe off any excess grounds from the rim, then press and lock the tamp into place.
If it's difficult to press down far enough, you've probably used too much coffee.
3 - Flip
Screw the water bottle into the tamp and your empty bottle into the basket then flip in one fluid motion.
Try to flip it quickly & smoothly without holding horizontally.
Check that it's straight, then stand back and admire your handiwork.
Check the drip rate
After setting up your brew, you should start to see drips after about 30 mins. Then it should drip roughly once per second or two.
- If your first drip takes longer, you may have packed the basket with too much coffee for how fine your grind is. This means your whole brew will take longer, and be richer in flavour.
If after about an hour no coffee is visible in the grooves, you may want to try again with less coffee or a coarser grind, because your brew might take very long to finish. Just flip ATMOS (over a sink) so that the water is on the bottom, disassemble and try again.
- If your drips are too quick, or you find the coffee is weak - try more coffee next time.
After Every Use
Give ATMOS a light scrub with the included brush, making sure the holes and grooves are clear. The bottles should also be cleaned thoroughly with detergent, and rinsed well. Dishwasher Safe.
After Extended Use
1. Dissolve one tablet in a tub of water.
2. Place ATMOS and bottles in the solution.
3. Ensure all parts are fully submerged.
4. Leave to soak for 15 - 30 minutes or brush until clean.
5. Rinse thoroughly (at least twice) in fresh water after soaking.
6. Do not leave the descaler solution to dry on ATMOS as this may
cause discolouration. Wash hands / gloves after handling product.
Mastering The Art
Beans: Cold drip coffee extracts less acid and often has a smoother flavour than hot coffee. This makes it ideal for single origin roasts, as the individual flavours are easier to distinguish. We love using an Ethiopian Keffa Wush Wush, that makes a super fruity, delicate brew.
Brew time is impacted by the amount of coffee & water, coffee coarseness and humidity, as well as how fresh your coffee is and the temperature of your water.
Flavor is impacted by type of coffee, freshness, water quality and brew time.
Amount: We find that the amount of coffee has the largest impact on the brew time.
Try weighing your coffee and altering the amount while keeping the grind constant (and recording the results on your brew card).
Grind: Then try altering the grind while keeping the amount constant. A finer grind will compact more closely, slowing the water's flow and releasing more flavour. If you're really serious, using a sifter like the KRUVE will help you know the exact size of your grind.
Water: The purity, source and temperature of your water will affect the taste and speed of your brew. Using chilled water may slow your brew down, giving an even smoother flavour.
Weather: The temperature, humidity and pressure will all affect the flow rate to some degree. If you want to get scientific, try recording these on your brew card as well - or set up in an airconditioned room, or the fridge.
Storage: How you store your coffee, before and after grinding will affect the speed and flavour too. It's best to keep your coffee in an airtight container and grind it just before use. Some people like to use vacuum coffee canisters to remove the air and humidity during storage.
The nature of using atmospheric pressure to control the flow, means there will be many factors with a small influencing the flow rate. If you'r aiming for perfect consistency, try to keep as many of these as possible constant.
- Check that the grooves are smooth and free of obstructions like coffee grinds or dirt.
- Check that your kitchen bench, or surface you are using is level - try finding a more level surface, or placing a piece of folded paper under a plate to level it.
- If your drips are coming early (sooner than about 20 minutes) try using a finer grind or more coffee. ATMOS is designed to drip slowly, and the grooves may not work as well if the flow rate is too high
- Wetting the grooves before starting the brew, can also help increase the capillary action, making sure your coffee ends up in the bottle.
The flow doesn't start
- If your coffee fill level is below the MIN indicator, the water may not be drawn through the holes in the tamp. Try using more coffee, and if the the brew get too slow, use a coarser grind.
- Check that the water from the top bottle is flowing into the tamp. If not, try unscrewing the top bottle a few millimetres to allow the water to flow into the tamp more easily.
