NOW: Coffee Breakdown; Why it’s a good morning choice, and ways to keep it warmer longer

A lot of people all across the world like to enjoy a nice warm cup of coffee during the morning. If you are looking for that caffeine pick me up or just a burst of warm flavors that cup of coffee is a great choice. Coffee can be broken down into two main groups; a light roast or dark roast. A popular light roast of coffee is the breakfast blend, while a popular example of a dark roast coffee is a French blend.

Light roast coffee is made when the coffee bean is roasted at 350-400 degrees Fahrenheit. This cooler cooking temperatures allows most of the coffee bean oil to remain within the bean itself. A dark roast bean is cooked at 460-480 degrees Fahrenheit. Due to the warmer temperatures the coffee bean oil is brought to the surface, giving the bean a more shinny look. Both roast's of coffee do have positive health impacts.

Coffee helps to impact the Cortisol hormone. Cortisol helps to regulate the amount of sugar in the bloodstream. If you are looking to get the most impact out of your cup of coffee in connection with your Cortisol levels, drink your cup of coffee an hour after you wake up, or between the hours of 9-11:30am and 1-5pm. This is the time period in between Cortisol maximums, so you get a little extra kick from the coffee's caffeine making you more alert and focused.

During this time of year keeping your coffee colder, longer can be a little bit more of a challenge. If you are struggling to keep your coffee warmer, it may be the type of material your thermos or mug is made out of. A thermos with insulation improves the duration your coffee stays warm, with the best insulation being vacuum insulation due to airs relatively higher heat capacity in comparison to plastic. A stainless steel vacuum sealed thermos, like a Yeti thermos is your best option, especially in comparison to an all plastic mug. Plastic has a medium heat capacity, but provides less insulations.

There are two main modes of heat transfer that takes place from the coffee to the mug, and then to the air surrounding the mug. Conduction takes places as the heat from the coffee transfers through the mug walls to the outside of the mug. Convection takes places when the warmer outside layer of the mug gives heat to the air outside. So when the temperatures are colder this time of year, this transfer of heat happens quicker, resulting in your coffee cooling quicker.
