I maintain, after PROPER seasoning (20+ lb) and with shots prepared identically, slower RPM will produce fewer fines and faster flow. That graph did not indicate either of those requirements had been met and was provided by the distributor. Until you can change no variables and pull back to back to back shots that run within 0.1g and

Neither formula contains chlorine. The classic does contain some chloride (about 16 mg/L Cl⁻ ion) and the espresso formula does not. The espresso formula also contains that bicarbonate which should make it better from a corrosion risk perspective. Per Taylor Minor of TWW: "Third Wave Water capsules - add to water for better

So what did you try next?

Let's say you have a pour over that's 1:15, e.g. 10g of coffee and 150g of water. About 2x10g of water is retained in grounds so you have about 130g of water in the cup. If you make an immersion brew and want it to be the same strength, and you get the same extraction percentage, then you'll want

It does read only to the nearest gram - for me that's not an issue. If you look under the tray (where you put the object to be weighed) there is a little raised rim that

I haven't solved this yet. Seems like a 30-50% increase in costs since my last order. Bags with valves and zippers are running in the 70+ cent range for a 16oz back. Shawn's is 73 cents in my size. Last time I bought bags they were 46 cents each. Hmm

Shawn in case you aren't aware, Tricor Braun Flex (formerly Pacific Bag) bought PBFY now as well

I have a Rocket R58, which I can say from experience has a similar/same interesting behavior: if the brew switch is engaged at (or even shortly after) power-up, the pump does not run. Rather it locks out and eventually registers an error. Since my machine is plumbed, I was very happy when I accidentally discovered this feature by
