Difficult. Gawith Hoggarth Cherry, or Abraxas Firedrac. Or any non-coarse Abraxas actually, the premium and Cafe(11?) were so good. My god I crave their offerings.
Honestly I suggest a variety of grinds and moisture content because what works for others might not work for you, and just don’t forget that what works for you may change over time. My nose doesn’t get on so well with many of the coarser moister types mentioned here for example (though I really love the aromas), because I get irritated, front and back drip and so on. So I tend to stick to mostly the medium-fine end of the spectrum. Been much happier here, though you’ll need to get your preferred method down as you get used to it.
I think Wilson’s is the place to go for SP, personally. Gold Label, Tom Buck, Grand Cairo, Grove- all good to me, and all a different twist of the SP theme.
