Has anyone tried caramelizing lactose?

I am working on a creme brûlée stout recipe. The beer has been made, 1.100 down to 1.025 with 4 ounces of lactose in the boil. I want to add some dark caramelized sugar to give it that burnt sugar element. I started thinking about the idea of caramelizing lactose, as it is not fermentable and so maybe more of this flavor I'm after will stick around. I did a little research, and was pleased to find that not only will lactose caramelize but that it tends to hold volatile aromas longer than other sugars, as per this article
http://www.usdec.org/files/pdfs/US08D_08.pdf
So I'm excited! Has anyone tried anything like this? I am thinking that along with the vanilla beans, the lactose and caramelized sugar I should be able to pull off some sort of a custardy burnt sugar thing. I'll post results to this thread - maybe this will work!
 
I haven't tried anything like this, but it sounds like it would be delicious. I'll be adding lactose to my banana split stout whenever I get around to brewing it, so your post has prompted me to consider trying your idea out. If you do it before I do, let me know how it turns out and I will do the same if I brew it before you do.
 
Sounds fair! I may do it this weekend but likely it will be next.. Or next ;) I'm pretty backed up.
 
Yeah, same here. I've got a lot of brews planned, but this idea is so exciting, I may bump my English pale ale to do this. It would make a better fall/winter beer anyway.
 
Cool idea! I can't wait to hear more about it. I'm all for caramel! Beer and caramel = win win!
 
Hmm...haven't done anything like this either but also am curious how it turns out. Would you be willing to post your full recipe and comments when you are done with it? Sounds like it would be a fantastic cold weather brew.

Yes I will once it is done. I'll post it up in the recipe section and link back to here.
 
Well, just so you know, it may be easier and more flavorful to caramelize regular sugar. Lactose doesn't have much flavor by itself- ever stick your finger in the bag and taste it? Once you caramelize regular sugar it becomes unfermentable- if you caramelize it, all that flavor is going to stay in your beer.

What source says that caramel is unfermentable? I know whatever has carbonized won't ferment, but I'm pretty sure everything else will.
 
Well, lactose is already unfermentable as it is, so caramelization wouldn't change that. But after a quick search, daksin seems to be correct. The reactions that occur during caramelization form higher molecular weight sugars that I'm assuming are unfermentable.

EDIT: After thinking about it a bit, this actually makes some sense. When you caramelize sugars in the boil, that flavor also remains, so it's not unreasonable to expect caramelized sugar added during or after the boil to exhibit the same behavior.
 
Interesting. I may have to try an experiment with that sometime. It would be easy and cheap to caramelize a little sugar and see if it it fermentable.
 
More research! Apparently table sugar doesn't take part in Maillard reaction because it is not a reducing sugar. I'm not sure exactly what constitutes a reducing sugar, but table sugar isn't one while lactose is one. This means that caramelized lactose would have a multitude of yummy flavors from the Maillard reactions while table sugar would just taste like caramel. This makes the decision for me... lactose!
 
I'm feeling smarter and smarter about this ;)

Seriously! This is such a great idea and now I am even more excited by it than I was before. I've got to wait just shy of a month before I can try this in a brew, but I am going to make some lactose caramel this weekend and see how it tastes. If all goes well it will end up in my Banaynay Split Imperial Stout.

EDIT: Just to put it out there, apparently the Maillard reaction requires the reducing sugar in the presence of amino acids, so I am going to make it with skim milk to keep the fat out of the beer. I'm not sure how much lactose there is in skim milk, but I'm pretty sure it's not enough to get a good flavor out of the caramel. I'm probably just going to use a standard caramel recipe but use lactose (obviously) and skim milk instead of water.
 
Last fall I threw together a four pound batch of homemade syrup from the directions in this thread,https://www.homebrewtalk.com/f12/20-lb-sugar-jar-yeast-nutrient-114837/. I subbed a pound and a half of lactose for table sugar and it made some pretty darn tasty syrup. I made the double cooked syrup and the reactions seemed to happen at a lower temperature than what the recipe indicated. I am wondering if maybe the sugars in lactose don't convert at a little lower temperature. Or maybe my thermometer is off, but something to keep in mind when you make your caramel.
I used my syrup in a Dubbel Style Cider experiment, and it fermented down to 0.995 so I think cooking the lactose broke the sugars down so they were fermentable, but the flavors were there and that is what we are looking for.
The cider turned out darned tasty, btw, better than I dared hope for.
 
You are correct. In my above mentioned research, I did read that lactose caramelizes at lower a temperature than table sugar. I assume the same is true of the Maillard reactions. Also, it's encouraging to know your syrup came out super tasty.
 
I like this thread, i was going to attempt a creme brulee stout, but was going to reduce my first runnings, i may use your guys route instead if it turns out to be the best way.

You used caramelized lactose for this? If so, how much?

Made a Syrup out of Table Sugar / Water. Cooked it down till it hit right temp... Became really thick and Carmel Tasting and colored also. Cooked til 290* was hit.

I've out caramel in beer before, and caramelized wort but never lactose. That's what we want to do! Congrats on your first AG beer

Thats why Brewing is so great... Doing different methods... TY... I would like to know how it turns out if you attempt a Lactose Carmel~ization.. :mug:

Your subscribed. My wife just found my 2 lbs of vanilla beans I hid from myself and I'll get a pound of lactose with my MoreBeer order on Tuesday so it's time to move this baby to secondary. Stay posted for results. I want to do a dry caramel method but I'm a little leery because I'll only have the one pound so I can't mess up, so I'll probably do a wet start caramel.
 
So I tried doing a lactose caramel with skim milk this weekend. Let's just say I wouldn't want F up perfectly good beer with whatever it is I made. I think the best course of action is going to be to use a straight lactose syrup and caramelize it. Using the skim milk to have proteins present for Maillard reactions didn't work out as planned. Next time I hit up the LHBS I'll grab some lactose and see what I can do with it. I'm excited to hear about your results, bottlebomber.
 
I just used a pound of table sugar, a few tablespoons of water, and a drop of lemon juice. Heated it slowly until the mixture melted and caramelized, then added it to my wort.

It was hard caramelized, not a syrup. And it dissolved well in the wort.

Lactose caramel sounds interesting. Looking forward to getting more info on it.

Supposedly you can use DAP to get the necessary nitrogen for a maillard reaction.
