This topic is very interesting to me. I recently enjoyed a Rochefort 6 and was intrigued by the black flecks in the bottom of the bottle. I've had many bottle conditioned beers but I' d never seen flecks like that before.

Rochefort has a lot of floaters.

Yeah, I get Rochefort sometimes that has a fairly uniform sediment in the bottom with no floaters, other times even chilled and undisturbed it has lots of floaters. I read where Gordon said that a beer with lots of floaters in suspension is often past its prime. Although it's pretty hard to picture a 10 ever being past its prime.

I have a mash question.  It is rumored that it is the following step infusion mash: 135-145-165-172° F (57-63-74-78° C). Would you advise that I do this?

BTW "Fermentation begins at 68° F (20° C), and the temperature rises to 73° F (23° C) during six to seven days of primary." (BLAM)

Had a 6 yesterday, no floaters. Expiration date: end 2020!

Referencing BLAM:

"...pH drops to 5.8-5.9 in the mash, with mineral acid used to drop the pH to 5.2 in the kettle."

That suggests that the water may stay relatively untouched, no?

I'm not sure whether I understand this completely. Does it mean I brew with water with high alkalinity and then use phosphoric acid to drop the pH during the boil? How do I calculate that?

I'm not sure I do either!

Seriously though what you described is how I interpreted it.

This page inspired me to try a Rouchefort, never had one before. The liquor store by my house only had a 10 so I guess I'll start at the top.

That's awesome Nate.

The 10 can be a bit boozy when it's young but are still delicious.

If you have the will power to let them sit for a while you'll be rewarded. I had one in January for my birthday that had been aging for about 7 months. Awesome.

I personally enjoy the 8 the best, then the 6 and finally the 10.

The 10 is one of my favorites in the world. I do like all three immensely, but like the 10 best.

Do you agree with my assessment on aging the 10?

Oh yeah. Can't go wrong aging it. Though I kinda like a lightly boozy one. Kind of a rum-soaked raisin thing.

Rochefort 8 is my absolute favourite beer, the 10 runs it close though.
