Coffee contains many phytochemicals, antioxidants and other nutrients that research has shown as beneficial to our bodies. But unfortunately, drinking coffee can sometimes cause acid reflux or similar issues. Luckily, some research has shown you can still have your daily coffee(s) if you brew it cold. Coffee brewed hot is far more acidic than cold-brewed, according to a number of scientific studies, and some say cold-brewed coffee even has a sweeter taste because of its lower acidity.

In general, your body requires a delicate balance (pH) of acidity and alkalinity to function and heal. The human body thrives with a higher level of alkalinity than acidity, and the foods and drinks we ingest determine, in part, our pH levels. When you drink high-acidity coffee your body’s pH becomes unbalanced, often creating discomfort for the consumer.

If drinking hot coffee causes such issues for you, try switching to cold-brewed. The benefits will still be present, but hopefully the discomfort won’t. If you truly prefer hot coffee, simply brew it cold and strong, and mix in hot water before you drink it. Making this small change in your routine could mean the difference between feeling bad and feeling better.

    Components list now also includes wooden frame pieces. We built a quick frame from MDF, although we are thinking about a laser cut acrylic frame for Version 2.

    The frame creates a series of stacked boxes which houses the glassware perfectly. Marking this project as done for now, while we enjoy our first batch of cold brew coffee!

    After ordering a custom beaker and some flasks, they have finally arrived!

    Flat bottomed flask (2000ml) for catching the coffee after the drip system

    A round bottomed flask (2000ml) for holding the ice, plus a stopper valve (full assembly) for letting the melted ice drip at a constant rate into the beaker.

    Custom designed beaker (1000ml) with clamp and drainage hole at the bottom. The grounds will go into this beaker and the water will drip through slowly to the flat bottomed flask.

    The old coffee machine looking on as we place the retort stand that will hold the cold brew equipment. Stand has a very heavy base and is solid in order to hold all the kit!
