I have been roasting single origins for the past year and am wanting to get back to blending so, I just ordered each of these (my old faithfuls) from Brendan @ BeanGreen :
Brazil Daterra Estate Sunrise - pulped natural RFA Cert.
Colombian Bachue Supremo
Costa Rican Tarrazu - SHB
Indonesian Sumatran Mandheling - Blue Batak
Any suggestions on a nice punchy blend? I make 95% of my coffees as flat whites with the occasional espresso and want high body and low acidity. I do have some robusta to throw in in small quantities to round things out.
I like roasting in 400gm SO batches in the KKTO and then blending post roast but can reduce a batch if necessary as long as I end up with close to 1.7-1.8kg of brown.
