Not much time, other than to say we tried the Otto today and we failed miserably

The Otto guidance suggests fairly fine coffee, but this all relative to the capabilities of your grinder & the unusually deep portafilter on the Otto allowed us to put way too much coffee in. As you would expect we were greeted with a chronically over-extracted brew

On the second attempt we faired much better as we weighted out 16g with fine scales, but we still over extracted in a big way as a result of having the grind too fine

Next time we will run a much coarser grind and hope to come much closer to being ‘in the zone’
