Cold Brew Research

Scientists recently took a deeper look into how cold brewing coffee works; the chemical changes; how to brew the perfect cup. They couldn’t meet as planned due to the Covid-19 pandemic so they had a virtual meeting.

They looked at the diffences in types of coffee used to see the different compounds left in the coffee. The looked at different ratios as well.

They found that caffeine contents and antioxidant levels were similar in hot and cold brewed batches for lighter roast beans but it varied more for medium and dark roast beans. They found the hot brewed coffee had more antioxidants in the darker beans. The darker the beans the more the difference. Also in the darker roast, the acidic content was less.

A Coffee Break

I took a coffee break last week. I went a full week without drinking coffee. The main reason was to see if I would sleep any better without my cold brew. It did not make a difference. What I did that week was drink more tea. I drank green tea, Earl Grey tea, a flavored herbal tea, and a flavored black tea. For a really good collection this winter try this Winter Solstice Loose Leaf Sampler. The box has a handy guide for how long to steep each type of tea.

I also treated myself to this tea infuser for loose tea. Rather than buy a special tea cup that comes with an in-fuser, you can turn all your own mugs and cups into tea infusers.

I am back to making my cold brew but it’s still nice to have a cup of tea in the afternoon or evening.

A New Way to Make Cold Brew

There’s a new cold brew coffee maker out there. And it’s fast. Just 4 minutes to your cold brew happiness. FrankOne started in Bogota, Colombia as a Kickstarter campaign. The idea was to brew using vacuum called VacTec™.

It brews using a reusable filter. It pulls the water using vacuum through the coffee grounds. Hot coffee can brew in a mere 30 seconds! It takes just 4 minutes for cold brew instead of 8-12 hours.

Jägermeister Cold Brew

Jägermeister has indeed developed a blend of their Jägermeister in an herbal (blend of 56 herbs, blossoms, roots, fruit) liqueur with arabica coffee and cacao. It is not yet available but will be the beginning of 2020. You can sign up to be notified on their website: jagermeister.com

It has 33% alcohol, so maybe this won’t be your daytime drink of choice. It is meant to be served in frosty shots (with about 10% of the caffeine found in a normal cup of coffee).

Hot vs. Cold Coffee

Some people like their coffee hot while some like it cold. There is a difference between iced coffee and cold brew so mistake the two for the same thing. Iced coffee is put on ice after it has been hot brewed. Cold brew never sees warm water.

  • Hot coffee has more antioxidants than cold brew.
  • Most cold brew has less caffeine.
  • Hot coffee makes you feel warm and cozy. People have warmer feelings toward someone holding a hot cup of coffee.
  • Coffee can help prevent having a heart attack.
  • A whiff of coffee brewing in the morning can help wake you up and make you feel less stress.
