S-33 is NOT Belgian. It is the old Edme ale yeast from 15 years ago, resurrected. It was the standard yeast thrown into a lot of homebrew kits. It is actually a very good yeast, but English in nature, not Belgian. My own notes that I've compiled from various sources over the past couple of years:
"A general purpose, widely-used ale yeast with low sedimentation properties that can perform in beers up to 11.5% ABV. This strain is extremely consistent, with excellent wort attenuation and a superb flavor profile. Flocculation: Low. Attenuation: 75%. Optimum temp: 59°-75° F. This is the old Edme ale yeast."
I haven't used it in about 15 years so I don't have any more specific comments about flavor or anything. But from what I gather from many sources, people like it, and I wouldn't hesitate to use it again. I might have to give it a shot sometime. Maybe in a bitter or ESB or something like that. Even an IPA. It's certainly versatile... and it's certainly NOT Belgian, contrary to sources up to and including the manufacturer themselves!!! Fermentis... they don't speak English so good, eh!
