I reactivated some starter that had been in the refrigerator since July 2019.
I'm pleased with the results. FWSY Overnight Country Brown. I used commercial WW flour, rather than the home-milled wheat berries. Next batch I'll use home-milled WW.
Much better crust and crumb than the 'pseudo' sourdough starter from the Poilâne book.

The yogurt + commercial dry yeast jump-starts things for the beginning baker, and avoids cultivating a starter from scratch, which can be discouraging to some.
If leftover Yogurt/ADY starter/pre-ferment is kept and fed, it eventually becomes sourdough.
The Poilane bakery doesn't really want to give out their secrets, because they ship thousands of loaves/day all over France, EU, and the US.
according to one Amazon reviewer, the book allows an approximation, but not a real imitation.
I may pick up a copy at $20, which is current Amazon price (MSRP $35 US), as an homage to the family.

I posted my experience with making the Poilâne-style starter in this post: http://www.thefreshloaf.com/node/62690/poil%C3%A2ne-sourdough-attempt
I included photos of the recipe for both the starter and the bread.
In my opinion, both the starter and the resulting bread were pretty meh.
I did this follow-up post to show the contrast between the Poilâne loaf and a 'regular' SD starter loaf from the same kitchen and baker.
