comment Why does WLP002 sometimes attenuate more?
Thanks for your answer! Pardon me for asking, but is not shaking the carboy bad for the beer, as in O2? On the other hand, the amount of O2 left in the carboy at that time is probabliy very small. At what temperature do you ferment?

comment WLP036 (Düsseldorf Alt) and cool temperatures
Thanks! SG is now 1.018 (target is around 1.013), and it is still fermenting, albeit slowly. I have never used this yeast and was amazed at the speed of primary fermentation. Ambient temperature is now 16 C after I moved it to a different location, but I am considering moving it to room temperature.

comment Why do kit wines age differently?
I think that your kit wine would be even better at 12 months. Similarly, from-scratch wines would be drinkable after 6 months. So I don't think that kit wines age faster.

comment Belgium clones leffe brune
Seems hard to find a clone recipe. But why not brew a dubbel and see how one can adjust that?

comment Different fermentation procedures for fruit wine
Thanks! I was thinking more or less the same: that the fermentation on the fruit -- with possible nutrients -- acts as a kind of "starter", allowing yeast to multiply and build up reserves for the main sugar-fueled fermentation.

Thanks! You are basically saying that underpitching may lead to overattenuation?

comment Why does WLP002 sometimes attenuate more?
Thank you, this is a good idea. I actually think early flocculation may be part of the problem. However, I do not understand 83 % attenuation at mash temp of 66 C. I think I should check the calibration of my thermometer.

I would like to read more about underpitching 002, if you have explicit sources. In fact, I may have underpitched slightly but not much; about 0.5 mill/ml/deg plato. However, the temperature may have been slightly low during the second week, about 17 C. May explain early flocculation. Still, I think 83 % attenuation is much on this beer.

Thanks for the answer! However, please explain to me: How can underpitching or underaeration lead to overattenuated beer? True, it may be that I underaerated, and that the fermentation atcually got stuck before bottling. However, WLP002 attenuating to more thatn 80 % at 66 C mash temperature? I find it hard to believe.

comment To Squeeze or Not To Squeeze the speciality grain mesh bag?
@brewchez Thank you for the clarification. So tannin extraction by, say, oversparging is due to rising pH?
