For a 470 g charge , I usually start at 2 . 5 3 . 5 kPa , lower it around 160 C or 170 C to 1 . 5 2 . 0 kPa , and then I ' m around 0 . 5 1 . 5 going into first crack . I ' ll often drop it to 0 . 2 kPa or lower part way into FC to prevent the flick delta BT increase . It changes for each bean of course , but this is my usual range . I have the T , vacuum out the pipes every roast , and I ' ve never cleaned my pipes or drum after 200 roasts but probably should ! .<| sep |> Kinda unrelated but i once stepped on a thistle while I was playing in my grandmother ' s garden . Hurt like hell , I don ' t recommend it . <| sep |> Lol I love autocorrect . Thanks for catching that p <| sep |> Shiny hunts are always fun .
