 In the production of our espresso, we used a Baratza Encore 485 grinder, a
 star anise bottle as an improvised tamper, and an Aliexpress bottomless

+We dialed in four coffees, most from local roasteries:
+- *Lotus* from Ca Phe: medium-light roast
+- *Holy Roller* from Heretic Coffee: medium-light roast, complex, grain notes 
+- *Puerto Rico* from Radiant Coffee Roasters: medium roast 
+- Trader Joe's French Roast: very dark roast

+Ca Phe *Lotus*, while promising for french press, was undrinkably sour no

+fine as the grinder went, pull times as long as 30 seconds. I suspect the 
+pressure of this machine is not enough to get good extraction on lighter and
+more acidic coffees. Unfortunately, we lack the facilities to properly test
+this hypothesis.[1]

+Heretic Coffee's *Holy Roller* provides a nice complex and grain-forward flavor. 
+The Heretic owner explained to us that they had designed the roast to make good
+lattes, and it sure did. After the complete failure pulling the *Lotus*, we
+were pleasantly surprised by how well it worked given the lightness of the
+roast. This one will remain a household favorite for lattes,

 ## Footnotes
+[^1]: Though portafilters with pressure gauges exist, this machine is a nonstandard basket size. It would likely require custom machining a portafilter for use with a pressure gauge. We would be interested in undertaking this project had we the time or funds.
