I'm still dialing it in, but at 11.36g in / 41.73g out, it was pretty good. Still not there, but closer than I thought on the first pull. I vaguely taste a fruit (apple maybe?) and some cacao. Not so much milk chocolate, as stated on the bag, and it's a bit more acidic that I would expect from this roaster, but both of those points could be just it not being dialed in yet.
It is, indeed, a light roast. I usually do around 1:2 with darker roasts, but I've noticed that the BBE does better with longer shots on light roasts. I tried 1:3 on the Blue Bottle, but 1:4 tasted so much less acidic, so I started with 1:4 on this light roast. I'm thinking pulling closer to 1:3.5 tomorrow morning, and go from there. I wouldn't mind getting suggestions :)
I've gone as far as 1:3, 1:4 just sounded like quite the stretch to me. I'm still fairly new to espresso, so by no means an expert! If it tastes good, you're probably on the right track.
