Ok, so I already mentioned my feelings about Jailbreak..
I have now tried 3 variants from HasBean...
1) Jailbreak: terrible, bitter dirty flavour with a thin paint stripping finish. would never buy again.
2) Kicker: too bitter for me, better finish than jailbreak and smoother but would not buy again.
3) Blake: more cojones, richer flavour, great for macciatos, a little too astringent as an espresso but still tastier than the other 2. Will buy again.
Disclaimer! I like bold, rich coffee flavour. I hate astringent acidy flavours. My ideal coffees are the beautiful back street of Naples espressos (where they still use those awesome antique lever machines) and the kiwi double macchiatos. I do not like milk flavoured coffee. I want to taste the stuff. and I want it to be smooth, creamy.
None of the above coffees is the best I have tasted but you dont know unless you try.
