Notes

For a fruity, spicy Belgian character there is no clean substitute for Belle Saison; SafAle T-58 is the closest dry Belgian strain but does not attenuate anywhere near as far.

Belle Saison is a diastaticus strain that finishes at 86 to 94% attenuation; T-58 finishes around 70%. If you want the bone-dry saison finish as well as the phenolic character, pitch T-58 first, then add a champagne strain such as EC-1118 to push the last points of gravity down.
