Hualien: two drums on the coast
East-coast roasting, dehumidifiers included.
Humidity as a process variable
Every roastery on this coast runs a dehumidifier all year. Without it the first crack arrives late and unevenly.
The workaround is longer drying phases and slightly larger batches, which is why east-coast roasts tend to be a little more developed.
On the east coast, freshness beats variety.
What they buy
Luye and Ruisui lots are bought by the sack, often the week they are milled. The distance is the advantage.
Ask for the Taiwanese list; on this coast it is usually longer than the imported one.
