Just transferred a French Farmhouse Ale and used Wyeast 3711. Started at 1.062 and fermented for 2 weeks at 68.

When I transferred, it was down to 1.002. I use a refractometer and NB's online calculator.

Can this be right?

It's possible, but yeah using a refractometer for FG is going to leave you w/ less than desirable accuracy.

What was the grain bill and mash schedule like?

Double check with a hydrometer, but it is very possible that it is at 1.002.

3711 is a beast and will often finish that low.

Grain bill was:

6.75lbs Vienna
5lbs Munich
10oz Carawheat
5oz Caramunich
5oz Melanoiden

152 for 60 minutes.
This is the recipe that Two Brothers Brewing gave me.

I normally use a hydrometer, but thought I would give the refractometer with NB's calculator a test. When I keg next weekend, I will double check and see if it is right or not.

I got a weird reading with the APA I also transferred today. I think it is the calculator.

Most accurate calculator I have seen is this one:

Wy3711 could certainly bring 1.062 down to 1.002 with that grain bill and those mash parameters.

Sounds like the reading is at least a little bit off. That attenuation just doesn't seem likely w/ that grain bill/mash schedule.

I agree. With that recipe and mash schedule it probably will not get quite that low.

Just an update.

Kegged it today and it was at 1.008 so the calculator was way off.

1.008 makes A LOT more sense.
