Le Bijou line…
I typically let mine sit for at least a year.
They are pretty good ROTT (after a travel nap of course)
Good at a year…
Really good at 2+ years…
I once smoked a 5yo petite rob, followed (next day) by a 2yo rob…………about the same, with the 5 yo being just a bit “smoother”
Just pick one of your Le Bijou fivers, and smoke one out of it every 6 months……….keep notes……..and you will find your sweet spot
