All we've bought for a good 25 years now is San Francisco Bay French roast beans from Costco. Grind enough for each morning and brew our coffee manually with pour over filters directly into the mug of choice. My wife is always into a 20 oz Yeti and I normally do mine into a 10 oz Yeti. Other times, I brew into an 18 oz Yeti Rambler bottle and pour into a vintage (1940's/50's) Victor porcelain diner mug.
