The Victor crew came across an article* that seemed very interesting regarding the amounts of caffeine we are actually consuming is based on several factors.
One factor is what type of coffee you are brewing. Caffeine is actually a natural pesticide so it will vary in the beans dependent on where they are grown. If they are grown in regions where there are a lot of insects, the beans will adapt and produce more caffeine.
Another factor is the size you grind your coffee. The smaller the grounds, the more surface area they have. Different brewing methods use different sizes. Cold brew uses a larger grind while espresso uses a fine grind.
Water temperature can factor in as well. The higher the temperature the higher the extraction is. Cold brew would only extract about 75% of the coffee.
Brewing style matters as well. You completely cover the grounds with immersion brewing where you leave the grounds sitting as opposed to simple pour over.
You may have heard that slogan in a Dunkin’ Donuts commercial for their coffee. Well, Dunkin’ has taken it a bit further and has built a tiny house that runs on Dunkin’ coffee. It is powered on recycled coffee grounds. The oils are extracted to make a bio-fuel to power the generators that run the house.
They designed the outside to have the textures of coffee. It is decorated in Dunkin’s colors: orange and pink. The house has been recently listed at Airbnb if you are interested in staying there. It is currently in Nahant, MA.
This was made possible through a partnership of Dunkin, actress Olivia Wilde, and New Frontier Tiny Homes.
After a recent trip, this member of the Victor Crew wanted to drink cold brew coffee but wasn’t able to make any.
The first one was at a restaurant in Portland, Oregon. One of the more popular brands of coffee in Portland is Stumptown. It is not inexpensive. The 10 oz bottle of cold brew cost $4.50, but it was very good. Given a glass and half and half, I was able to make it tasty.
The other time I bought cold brew was from a Dunkin’ Donuts and had them add half and half. It wasnt as tasty as the more expensive one but it was pretty good as well.
The only other time I tried ready-made cold brew was from a Starbucks. It was actually too strong for me and they left no room to add a lightener.
Two former Googlers, Jake Knapp and John Zeratsky who worked on Gmail and YouTube, have some advice for handling your caffeine habit.
They suggest you not drink coffee first thing. Perhaps wait until after 9:30 am. Cortisol is highest before that so its not needed earlier.
They say that caffeine doesn’t give an energy boost but prevents energy from waning. “If you wait until you are tired, it’s too late.” Since energy level goes down after lunch, have your second coffee half hour in advance.
If you miss that second cup in time, they suggest you take a nap.
Instead of another big cup of coffee in the afternoon, switch to tea or espresso (small cup), which have less caffeine.
Use proper timing for your last cup. Caffeine half-life it 5-6 hours so if your last cup is 4pm, you will still have half the effect of the caffeine at bedtime.
