What are the best green coffee beans to start roasting at home?

What are the best green coffee beans to start roasting at home? We suggest the best coffee beans to use when starting roasting is probably washed Colombian beans. Most coffees that come out of Colombia are washed.

Why use a washed green bean if you start roasting coffee beans at home?

Washed green beans are a little more forgiving and can take a little abuse and still create a coffee that is drinkable! The Colombian green coffee beans are especially good for this and will reward you with something quite special once you have nailed your technique. They also have a lot to offer in terms of what you will get out of them. You can get a bright fruity coffee and a dark chocolate taste profile all from the same bean.

So if you’re new to roasting green beans at home, start by ordering some quality Colombian green beans and have fun trying different roast profiles. We suggest you start by dropping them just before the second crack. Then try dropping your beans towards the end of the first crack. There is far more to profiling coffee roasting but this is a good starting point.

TIP, try your coffee just after roasting and again in 3 or 4 days. In general, roasted coffee tastes better after a few days and will keep changing up to 24 days after.
