How bad are the Kirkland House Blend (Sbux) for a Ninja AutoBarista Pro?
I picked them out cause they seemed closest to roast date but then realized they're really oily, which isn't optimal for the grinder. Any long-term effects from a 5lb bag recently calibrated?
The bags also only show a BBD, is the roast date typically 12-mo from BBD?
Which beans would be best from Costco for this machine, the Lavazza?
