I'm a medium roast enjoyer. I've tried dark roasts and light roasts. Neither do the job. Right now my daily driver coffee is maxwell house breakfast blend that I buy in bulk in the big tins. On special occasions like holidays I will buy some pouch coffee. I like to get Volcanica brand from Amazon they make some really good coffee. I think I tried their Peruvian coffee and it was nice.
I've tried blue horse kona and I just don't like kona. I know a lot of other people think kona is great coffee but it's not for me.
Sumatran coffee is okay. I went through a phase were I drank a lot of that. But it's considered a premium coffee sold in pouches here in the USA and I needed to buy cheap coffee to feed my addiction and I gravitated to a medium roast breakfast blend.
