Ozeri digital scale
Amazon If you've got the pour over and the kettle, and you're committed to seeing this brew process through to the end, then take the red pill and get yourself a kitchen scale, too. This digital kitchen scale will help you achieve the ideal ratio of beans to hot water, so that you don't end up with a coffee that is too bitter or too weak.

Tucked inside your robot's dustbin is an air filter. It's designed to trap fine dust particles inside the bin as air flows through the vacuum. Over time these filters will become clogged with lint, hair and other physical debris. It's a good idea to inspect the filter each time you empty the bin. 

Andrew Hoyle/CNET This shot was much trickier than I imagined and I ended up taking this shot with my iPhone XS Max. That's because the sky was incredibly bright compared to the rocks in the foreground and the boat itself. I needed something called a graduated neutral density filter -- essentially, a piece of glass where the top half is darker than the bottom. By sliding it into position, it darkens the sky, helping to balance the exposure overall. 

My first stop was at this waterfall I spotted a short walk from the side of the road. Because I wanted a long exposure to blur the motion of the water, I shot using the iPhone's standard camera mode with Live Photos activated. I like the way the water streaks out as it hits the pool, but I didn't keep the phone still enough. Some of the rocks and landscape came out a little blurry. 

Tyler Lizenby/CNET Takeya Cold Brew Coffee Maker
Outside of an old-school Mason jar, it's hard to beat the low $25 price of this Takeya cold coffee brewer. The BPA free dishwasher safe plastic pitcher comes with an airtight seal and has a slim profile made to slide into fridge door shelves. With its fine mesh reusable filter, It's also easy to clean and makes solidly satisfying cold brew. If you want strong, concentrated coffee though, the Takeya Cold Brew isn't your cup of tea. It brews a weaker drink than other similar products. 

Whenever possible, I brew double shots of espresso for all my test runs. I make sure to record the weight of the grounds I use, plus the weight of espresso for each shot I pull. This data, along with readings from a portable refractometer, allows me to calculate two important percentages: TDS (total dissolved solids) and extraction percentage.

You can pull away dust clogging the filter by hand. A better method is to clear the filter by using a handheld vacuum. This way you won't let dust escape into the air or back onto the floor. Don't wash air filters though with water. 

To pull shots, I start with the suggested method outlined in a given machine's product manual. Usually that covers the amount of coffee grounds expected per shot, along with any guidelines regarding coarseness level. Likewise, I follow tamping instructions (light, medium or hard tamp) if the manual provides them.

On any robot vacuum, the first surfaces to come into contact with floor-borne dirt are its wheels and brushes. Dust and debris builds up around them as they rotate. Items such as string and hair are particularly challenging to these spinning parts. Remove them regularly to check if any of the troublesome objects have become wrapped around your robot's brushes and wheels.

$15 at Amazon Pour-over coffee
If you've never tried pour-over coffee, either at a local coffee shop or at home, prepare for a completely different world of coffee. If you have any inquiries relating to exactly where and how to use Wifi Controlled Lights, you can speak to us at our site. Pour over methods release layers of flavor you never knew coffee could have: fruity, chocolatey, earthy, floral, juicy -- coffee drinks can taste like all of these and more without going to the coffee shop. At home, try brewing with one of these, which each require their own type of paper filter. You'll add a little extra time to your coffee ritual, but you will be rewarded with a cup of piping hot coffee that will have you savoring every precious drop of flavor.

Whether you prefer specialty coffee, iced coffee, dark roast coffee or even anything a step above instant coffee, any of the above will help you explore new ways to enjoy great coffee. And for coffee enthusiasts, that's really what life is all about. As Johann Sebastian Bach said, "Without my morning coffee I'm just like a dried up piece of roast goat." Don't be a dried up piece of roast goat -- make a good cup of coffee.

Some gadgets even create cold brew in a fraction of the time it usually takes. The $109 Gourmia Cold Brew and $129 Dash Rapid are excellent examples. Both countertop machines complete the process in minutes, not hours.
