I would have to disagree with John. Is manual brew better than drip machine? I have had less than a handful of coffee nirvana moments, and two of them are from machine dripped. First one was at Terroir's open house tasting a Kenyan brewed through Technivorm, another time was at Esselon when Scott Rao was running the place and had his Yirgacheffe through Fetco. Scott has since opened Myriade in Montreal where you can get espresso drinks, Clever single drip, French press, eva solo and Hario syphon but machine dripped is not offered. George Howell at Terroir on the other hand is still championing Technivorm, a drip machine. Another person, James Hoffmann, after he played with multiple manual brew devices, asked are we throwing away our drip machines too soon? I have had good drip, bad drip, good Clover, bad Clover, good syphon, bad syphon, good single drip, bad single drip. I have had horrible shots from La Marzocco and Synesso, and decent shots from supposedly lesser machine/grinder. I think it is the person behind the counter, not any particular piece of equipment. The way I see it, the advantage of individual brew coffee is it's brew to order, the danger of drip machine is leaving the coffee in the pot too long. That however, is a training issue that can be addressed.
I personally don't think offering Americano instead of drip is a good idea. Some coffees work better as drip, Terroir's masterfully done Kenyans for example would not work well when extract through espresso machine.
