I have a B.S. in chemistry, so you can imagine I have a fondness for laboratory glassware.  That’s why the Ovalware RJ3 Airtight Cold Brew Iced Coffee Maker caught my eye.  But you don’t need a degree in chemistry to make coffee in this maker.  You simply add ground coffee and cold water and come back in a few hours.  You may wonder why anyone would bother with cold-brewing when there are so many coffee makers on the market that can produce a cup in seconds or a whole pot in a few minutes.  Well, cold brewed coffee has a richer taste and is 70% less acidic than hot brewed.  It’s a concentrated solution sitting in your fridge until you decide to dilute it to make iced coffee or heat it for a hot cup.  It also works great for brewing tea from loose tea or tea bags.
The brewer is available in a one- or 1.5-liter size. Â The carafe is extra-thick, lab-tested borosilicate glass that can even stand up to hot brewing. Â The rust-free superfine dual-mesh filter and the cap are made of 18/8 medical-grade stainless steel. The cap has a BPA-free silicone airtight seal. The whole kit is dishwasher safe.
Put ground coffee in the mesh filter, add water, and put the carafe in the fridge for 12-24 hours, depending on how strong you like your coffee. Â When brewing is done, remove the filter. Â You can store the concentrated coffee in the refrigerator for up to two weeks.
The Ovalware RJ3 Airtight Cold Brew Iced Coffee Maker is $29.99 for the one-liter size or $35.99 for the 1.5 liter size at Amazon.

Love the chemistry and coffee comparison, looks like something straight out of breaking bad!
I’ve never cold brewed tea, but will give it a go after reading this!
