Espresso:
Nothing exceptional here, overall I was quite disappointed.
Store St - SqM Sweetshop was the only option. It was OK. Just OK. And I like nice bright fruity coffee....
Craft - A SO from Notes that was pretty nice and syrupy and spicy. Really nice people (I told them the forums sent me).
TAP (Rathbone Pl) - Their house blend, bright and quite nice. Not that memorable.
Alchemy - San Sebastion - Really Orangey. Not that memorable.
Filter:
Much better here
Caravan - a rare Panama Geisha Natural (the same coffee was also available washed) brewed in a Chemex. Loads of ripe juicey stone fruit once it had cooled down. Really cool place and nice vibes. Very busy. Really friendly staff, had a chat with the Barista and bought a bag of the Panama.
Origin - Best coffee of the trip by far, Kenya Gatura. Incredibly complex and less bright than a lot of Kenyan's I have tried recently. This place looks amazing, very cool with a beautiful brew bar. It was quiet so I had a nice chat with the Barista about coffee in general whilst he took great care and attention and it showed. Absolutely stunning filter. I'm definitely going to be buying more of their beans.
Workshop (Clerkenwell) - Had a filter of a Kenyan I think. Brewed in an aeropress, although I wasn't given an option. It was nice but forgettable. Had a chat with the barista on the espresso machine who was friendly and sold me a bag of the current cult of done which is an SO Burundi. Incredibly busy.
Gentleman Barista's - really cool place that had more locals than coffee geeks. The incredibly friendly barista offered me a choice of 3 coffee's either as aeropress, chemex or v60. A v60 of a washed Columbian from a roaster I have never heard of before and have since forgotten (Sunday something?) was super clean and quite floral. When I asked about it the barista brought the bag over to me and told me about the roaster and the coffee and was just a really nice guy who clearly cared a lot about whether his customers were enjoying the coffee.
Always good to see what else is going on so thanks again for all the recommendations.
