Head Retention for Extract Beer
  • Hey everyone, I hope to get some help here. I've brewed 3 extract batches, each with a 3kg can of extract. The beers have been ok, but I'm looking for ways to improve them, especially with head retention. The foamy head of my beers dissipates quickly and leaves no lacing at all, so it looks like a flat beer. The bubbles are large, weak and gone in no time.

    Are there certain ingredients (here in Korea) I can use or is it a technique error on my part?

    Thanks a lot!
  • I'm extract, but have never had any head retention issues, however I don't use local extract so I'm not sure if there is any problems with that.
  • Kunk, the "local" extract is from Oz and UK, so maybe freshness is an issue. I've used Munton's and ESB. What brands do you use? Could you provide a sample extract recipe?

    As I said before, I just use the 3kg can of extract, no DME. Could that be a factor?
  • I've read that wheat will help with head retention. I believe adding limited amounts of wheat can build head without affecting the flavor of your beer. I personally haven't brewed with wheat yet, but you might want to look into it.

    Good Luck!
  • How long does it take for the head to dissipate? Does it pour thick and then completely disappear, or does a ring of foam remain around the edge of the glass? (For some beers, that's actually normal.)

    What style of beers were they? Was the extract pre-hopped? (ie. did you have to add hops?) Higher hopping sometimes makes for better head retention.

    Also, did you supplement the extract with DME, or with sugar, or not at all? (And if yes, how much?)

    What did you use to carbonate the beer, and how carbonated was it?

    I don't know much about extract-related issues, but wouldn't taste be a problem as well if freshness was an issue? (Also, if the extract cans were gotten here, I suspect the freshness issue might have more to do with warm storage after-arrival, and the stock turnover of the brewshop, than with the length of time spent in shipment. Or that's the impression I got from a visit to one shop here...)

    Another culprit I've seen for this kind of problem is that there's some residual soap either on some of your brewing equipment when you were using it to brew, or more commonly, on the cups in which you're serving the beer.
  • I use WilliamsBrewing extract, I like them because they have the specialty malts already in them. Yeah I would say it is probably soap or oil or something like that is affected the retention.
  • Kunk, how much does an order + shipping from Williams typically cost?

    Gord, I'll get to those questions after my son is asleep!
  • *How long does it take for the head to dissipate? Does it pour thick and then completely disappear, or does a ring of foam remain around the edge of the glass? (For some beers, that's actually normal.)

    It pours thick and starts to disappear very quickly. Although I can't say it's actually "thick", the the foam is not dense, it's very weak. Most of it is gone in a minute. A ring remains for a couple minutes more, then it's gone.

    *What style of beers were they? Was the extract pre-hopped? (ie. did you have to add hops?) Higher hopping sometimes makes for better head retention.

    I've done a Munton's Old Conkerwood Black Ale (Good Beer) and two ESB APAs (Beer School).

    *Also, did you supplement the extract with DME, or with sugar, or not at all? (And if yes, how much?)

    I supplemented the black ale and one batch of APA with 1kg of sugar. The other batch I steeped some Caramunich and Wheat malt.

    *What did you use to carbonate the beer, and how carbonated was it?

    I use 2/3 cup of table sugar per 1 pint of water for bulk priming. They are nicely carbonated. A good hiss and steady bubbles for a long time off the bottom of the glass.

    *Another culprit I've seen for this kind of problem is that there's some residual soap either on some of your brewing equipment when you were using it to brew, or more commonly, on the cups in which you're serving the beer.

    I use a very mild baby dish soap that rinses quite easily. Our serving glasses seem to be well-rinsed.





    I hope the solution lies somewhere here, thanks for addressing all these variables, Gord!
  • *What style of beers were they? Was the extract pre-hopped? (ie. did you have to add hops?) Higher hopping sometimes makes for better head retention.

    Also, I've added 2oz of Cascade pellets to the APA extract which was prehopped, as was the black ale.
  • Thought I'd chime in on this. I started using carapils for all my beers in a very small amount and have had no problems with head retention since. I am not sure why, but it has done the trick for me. About 100g crushed per 5g(or more if you like, crystal/caramel malt is supposed to aid head retention in addition to adding color and sweetness).

    Wheat malt is also very helpful for this as it adds a lot of proteins into the beer, and its the proteins that make the head. I am unsure if you can make that work in an extract batch, as wheat needs barley malt enzymes to convert to sugars and proteins and dissolve into the water. I assume that for just getting some more proteins in your wort it would be ok to steep crushed wheat, but I don't know for sure.

    You say that your beer is well carbed, what kind of bottles are you using? I have had issues with crown caps not carbing the beer as much as I would like.

    Another point here is that serving temperature matters. Beer around the freezing point has less head as the liquid has more of the CO2 dissolved in it and releases it much more slowly. Try letting it warm a little bit before opening the bottle and see if that does anything. Rinse your glasses with a little water before pouring the beer, just to be sure. And if none of that works, well its mostly aesthetic. If the beer still tastes good, just enjoy it as is.
  • Oats and Kunkemonster hit some of the important points. To add to them: I wonder whether you might not have thinned the beer out excessively using 1kg of sugar for 3.3 kg of extract. It sounds like a lot, at more than 20%. Maybe the thinness also accounts for a thinner head. I don't know, as I have little experience with extract.

    If you wanna test the soap theory, get an unused paper cup or plastic cup someplace and try your beer in that. :)

    How long as the beer sat in the bottle? How long did you let it carbonate and condition before refigerating it? If you're drinking it too fresh, or haven't properly chilled it (for a while) prior to serving I find the carbonation can be of a slightly different character: bigger bubbles, and less bubble stability. Or so I half-recall from my 100% bottling days...

    Oh, but a correction to Oats' last comment: wheat malt actually has very good diastatic power, and can convert itself fully without any barley. (You've tried a few of my 100% wheat beers, actually, Oats, but maybe I didn't mention the fact.) I'll post more about that in another post, but I just figured it'd be good to eliminate that misconception here. However, if you want to use wheat, you can't just steep it like with crystal: you need to mash it. ("Minimash" would be the pertinent approach, Mangy17.)

    You could easily minimash some wheat in some of your brewing water prior to adding malt extract, and in fact if you were wanting to make your extract more highly fermentable (ie. drier), you could pull the wheat out after mashing it, and then add the extract, and just let it sit for a while at the lower end of the mash temp range and let the enzymes from the wheat work on the extract, before boiling it. If you wanted to avoid that, you'd bring the post-mash water to a boil before adding your extract. I *think* that'd work, since wheat has relatively high diastatic power. (And, supposedly, so do oats!)
  • Oats, I'm using 330ml Cass bottles with crown caps. I try to sell a few so that's why I do that size.

    Gord, I guess I'm pretty impatient with the beer. I'll give it a week or two in the bottle at ambient temp, then chill it the freezer or fridge just long enough so it's ready to drink.

    I'll try a mini-mash next time, guys. Thanks a lot!
  • Hey guys, the answer to my problem has been found. Extended refrigeration did the trick. I need to follow the 2-2-2 process more faithfully. Thanks again for all your input!
  • I had the same problem with extract. Nothing worked. I switched to PM then AG, 100g torrefied wheat in each batch and usually 250g or 500g Carapils. Excellent head ever since.
