Split Belgian batch

You aren’t thinking of Duvel are you?  That is supposedly the origin of their yeast, but I hadn’t heard that about Rochefort.

I’m with you - I’ve heard that about Duvel, but I hadn’t heard that about Rochefort.

That being said, I just took a look at the yeast strain tree on suregork’s site, and I noticed WLP540 (Abbey IV) is in the middle of the United Kingdom branch of the tree. WLP540 is supposedly White Lab’s Rochefort strain, and supposedly equivalent to WY1762. This makes a lot of sense to me from a flavor perspective. I think this might bump my 1762/English ale experiment higher up my “to do” list.

yup.

someone in the other forum (the big forum) said

“Yep, the Belgians are a bit of a mess, I think the most interesting one is WLP540. The Ardennes wasn’t the best place to be in WWII if you wanted a quiet life, and Rochefort struggled in the aftermath. They got help from Chimay and used their yeast for a bit, then got a consultant in who found them a new yeast from Palm. So WLP540 seems to be a close relative of Ringwood, that’s more fruity, less fusely and much more alcohol-tolerant. Works for me.”

as well as the sure gork “map”

Digging deeper into the map a bit, WLP838, a lager(?) strain, is pretty close on the tree to 540. I’m wondering if the Rochefort strain can put out a faux lager using a big, well oxygenated pitch that is fermented cold. I’ll have to include that in my next go round with this yeast.

That’s how I always ferment 1762 and I guarantee it would make a very unlagerlike lager

? you ferment it in the 50s or so? how does it turn out?

Start at 58 the last couple times, so I retract the “always”.  Turns out like Rochefort.

thanks, appreciated. i struggle with belgian yeasts.
