What is a dual hopper coffee machine?
With two separate hoppers, you can easily brew two types of coffee without swapping beans or equipment. Most versatile dual coffee makers are great when your coffee routine isn’t the same every day. You can fix a fast cup on your way out the door or make a full pot when you have people over, all in one machine.
What is the 2 hour coffee rule?
Quick answer: the 2 hour coffee rule suggests waiting at least two hours after waking up before drinking your first cup of coffee. This guideline aligns with the body’s cortisol levels, aiming to optimize both the effects of caffeine and the body’s natural wakefulness cycle. If you drink coffee right after waking, adenosine hasn’t fully cleared, and your natural cortisol peak (the hormone that helps you feel alert) hasn’t finished rising. By waiting 45–90 minutes before your first caffeine, you allow your body to wake up naturally.
What is the 2:1 rule for espresso?
A 1:2 ratio means you use 1 part dry coffee to make 2 parts liquid espresso by weight. So: 20g in → 40g out. For example, we should aim to extract 36g of liquid espresso from the 18g of ground coffee in 30 seconds, giving us our target ratio of 1:2. Don’t be afraid to try different coffees or big changes in your ratio style, but when you find a coffee you like, stick with it for some time!If the extraction time is too short, the espresso will be weak and under-extracted. If the extraction time is too long, the espresso will be bitter and over-extracted. It is important to monitor the extraction time to achieve a well-extracted shot.
