Behmore Coffee Roaster - 1st roast

PNG Simbu 

High altitude 1500m 

So a dense bean.

These are Arabicas from the Central Highlands in Simbu provence.

1500m +

For a PNG Arabica from Simbu Province, the bean is typically a washed, high-altitude coffee with bright acidity, medium body, and floral/citrus notes. The roast profile can vary depending on your desired flavor balance.

Using P1 setting of the Behmore

Profile P1 (Default) - Hard Bean (Highest Heat Profile)

 All Centrals, Peruvian and Colombians

 Press appropriate weight button (100, 200 or 400), then press Start button

Note, Profile P2  is also for Hard Bean All Centrals, Peruvian and Colombians 

 P1 in Auto Mode raises the temperature as fast as possible without scorching (and doesn't cut the power). 

P2 in auto raises the temperature as fast as possible (like P1) and then it  drops in power to 70% at the 2/3 mark of the roast. It holds this power setting till 9/10 of the roast time where the power rapidly increases to 100%.

----------------------------------------------------------------

I Preheated the Behmore at P1 for 1.30 mins then placed the beans into the drum (with heat gloves).

start 100g dose

finish 86.2g 

thus 13.8% weight loss.

The programmed time changes depending on the amount of coffee.

100g has a time of 8.30mins

200g has a time of 12 mins

400g = 18 mins
