I actually use the vacuum tops a lot for wine so I will try them out. Point of using the refractometer is to pull small samples thou.

True, but when I really care about the numbers I always use a hydrometer. I usually pull a sample from my beer taps and degas with the wine tool or the foodsaver if it is out already. I like the fact that the beer is good, in a pint, and a sample being degassed to have my "finishing numbers." Then I don't overthink anything, because the beer is 100% done even if I didn't hit my numbers. If I were to sample with a hydrometer before I was drinking it and off, I would fool with it more than necessary. I usually just "reference" it with the refractometer while enjoying my first pint though, and that is good enough for me. I check at first, then come back a few hours later and look more accurately at the refractometer reading. There is always a difference in that time frame though by a few marks.

Thing is when lagering and ending up at 2.* vol co2, i need better readings to know when to crank down the spunding valve and start decreasing temperature, and the benefit of the refractometer is a small sample pulled.

Flananuts - Do you find that the dip tube contains an accurate sample of the beer fermenting in the rest of the keg volume? Or, do you pull enough to get beer from the bulk fermentation?

You know you make a good point. I may not be pulling enough sample to get an accurate read in the refrac.

I would think all the beer in the keg is the same. It all has working yeast making the same alcohol. I may be wrong so if anyone knows absolutely I would love to hear different.

Wortmonger - You're probably right.

When you guys are drawing off samples, do you just use the keg's natural pressure, or do you remove the spunding valve and add CO2 pressure while drawing-off to maintain consistent ferment pressure?

I agree, the SG has to be the same no matter where you sample from.

I use the pressure in the keg.

I would think that the racking cane in my setup would contain higher gravity wort if I was only pulling a small sample vs enough for the hydro sample since its under pressure.

Also, since the dip tube is at the bottom, how do you avoid drawing off a bunch of yeast and trub when you sample? I just took an ounce or so from a beer that I started pressure fermenting on Wed night, and it was pretty much all trub.
