Simple.
Mostly pils, touch of wheat to anywhere between 1.035 and 1.050. Bigger if you like big saison - I like the session/refreshin' from slightly more historically aligned (although even mine is stronger).
Noble hop, hall mit preferred, to around 30 ibu.
Step mash with 15 mins at 62, 40 odd at 68-70.
Ferment with 3711 (or the belgian or farmhouse -all 3 wyeast are great but french is my favourite), starting at reasonable ale temps but allowing to rise to ambient summer temps within 48 hrs. Ferment to fg, condition, then cold condition
