Quote History Quoted:
Where did you find out that pasteurizing removed B vitamins and anti-oxidants? What are you actually looking for, beer with active/live yeast in it?
A way to determine this yourself would be to check the bottom of the bottle for a thin layer or dusting of flocculated yeast. You can also stick to styles that lend themselves to bottle conditioning.

I did find out Sierra Nevada bottle conditions their beer, so that's a start!

I am familiar with the pasteurization process, so I am aware temperature affects nutrients. I did not realize pasteurization of beer required a fairly high temperature. To me, bottle conditioning would be fine, as live yeast is re-applied and nutrients are preserved.So yes...I am looking for beer with active/live yeast in it. The problem is may brewers do not do this...
Quoted:
What enzymes aren't denatured in the boil?
Why do you think that heating beer destroys vitamins?
Why do you think it does not? Very basic information related to heat pasteurization discusses how temperature affects both bacteria and nutrients. It has been proven over and over again that low heat milk pasteurization has a negative effect on nutrients. My understanding is the process for beer pasteurization (heat) involves a higher temperature than milk, which would further decrease the benefit from active yeast.
Honestly, I'm too lazy to chase down links and citations, so if you have some info disputing this, please do tell?
I am new to the brewery forum, so I will leave it to the experts, but if you have some vast knowledge on how the pasteurization does not negatively influence nutrients in beer, please educate me...
The information I have read indicates pasteurization of beer is not ideal if trying to preserve nutrients. I have also contacted more than one large national brewery regarding the issue and the few that responded have have all indicated pasteurization is not ideal if the goal is to preserve nutrients. Then again...how many people are actually using beer to get their nutrients? You might be surprised...
