Did a 12 gallon batch (split it into 2 carboys) 8 days ago and fermented ~73 using Wyeast 3638. Got great attenuation (86%). What do you think about cold crashing to say 30* to knock down some of the chill haze?
I wanted to add lactose and fruit extracts. when is a good time to do this?
I’d add the sugar and extracts before crashing.
How come? just curious.
Depends how you are crashing I guess. Personally I like to get everything mixed up early on so it will mature. I don’t like additives added late in the game as they don;t seem to meld as well as they would have if conditioned all together.
Just my opinion.
+1 on adding the lactose now. You can add fruit extracts at kegging or bottling.
Just curious why would you want to crash a weiss? If you want to crash I like to cool down to about 34 for 36-48 hours. You wont clear chill haze, but it will help yeast drop out of suspension…which to me you want in a weiss beer. Maybe Im misinterpreting your question.
Lactose … in a weissbier? Have to say, I’ve never heard of that one.
To me adding lactose will make it a bit sweeter to complement the fruit extract.
Right? I dunno. I wouldn’t use it.
Interesting. I’m not a big fan of lactose in beer, personally, but I recon I can see where that would work.
If you hear jackboots in the night, it’s the Reinheitsgestasi coming for you!
Wasnt there a recipe on the front page of the website a few weeks back for a Peaches N Cream Hefe with lactose and peaches?
LOL! 
Actually it’s not a Weissbier- more like a fruit beer. And after reading your responses I think i will add the lactose first (thanks Euge-makes sense what you said) then get the beer down in the upper 30s long enough to force carb for a few days. Then add my extracts and bottle. My intention is to produce a slightly sweeter version of a Blueberry wheat I did last year. Problem with the last one is the blueberry flavor was gone rather quickly. and that’s after double dosing with extract. Peaches N Cream Hefe is where i got the lactose idea.
OK another question:
I mixed a pound of lactose with 2l. water and was going to add to my 12 gallons of beer. is oxygen a concern?
Not if you boil it first.
