Which clear/white sugar works the best in pale Belgian beers?

Starting with the publication of Brew Like a Monk a few years back there seems to have been a shift in the way American homebrewers view the use of sugar specifically, and adjuncts in general in their beer. There was a time when it was assumed that adding any sugar to your beer was a betrayal of the principles that the home and craft brewing revolutions were founded upon (and a good way to make it taste cidery). Almost everyone now sees the value in using flavorful sugars like dark candi syrup, unrefined sugars, and sugars derived from things like dates, cacti, and palms. In addition many people even see the value of using a refined sugar to thin out the body of a high gravity (particularly Belgian) beer.

After doing two rounds of experiments with the more interesting sugars the question remains, which of the many plain/white/clear sugars available makes for the best beer? Most of the result will be determined not on the actual flavor of the sugar (pretty much every last molecule of each will be converted to ethanol by the yeast), but on the byproducts the yeast produce while fermenting.

Here is what visitors to this site thought about the question:

They all work fine - 44%
Clear Candi Syrup - 14%
Clear Candi Rocks - 12%
Cane/Beet/White/Table Sugar - 9%
Corn Sugar - 5%
Better to leave them out - 3%



I am planning on doing a third in my series of Belgian sugar experiments in the next few weeks using just those sugars. I'm not sure how it will turn out, but I suspect there will be some subtle differences between the batches. More details on the methodology and of course results to come in future posts.

Sour Cider

After good luck with a relatively straight forward cider last year it seemed like it was time for me to give a cider with some funk a shot (I am the Mad Fermentationist, right?). Some traditional apple ciders do have a bit of a wild yeast character because they were made from unpasteurized apples (the peel of most fruit are covered in sugar loving microbes), and if it doesn't work out I'm sure I could put 5 gallons of apple cider vinegar to good use...



As always hard cider is one of the easiest things to ferment at home. Just dump the cider into a carboy, add some pectic enzyme (I've used 1/2 tsp per gallon in the past, but this time backed it down to 1/4 tsp to see if I could still get a crystal clear finished cider), and pitch the yeast about an hour or two later.



In this case though instead of a clean cider/ale/wine strain, I used some of the slurry from the Wine Barrel Flanders Red (it started out life as Wyeast Roeselare Blend and Lost Abbey Red Poppy dregs ~18 months ago, but I have no idea exactly what is in there now). When fermentation didn't appear to have started after 48 hours I decided to pitch some hefeweizen yeast left over from my Weizenbock. Hefeweizen yeast may seem like a strange choice, but it is a somewhat popular choice these days. The idea is that the fruit esters will boost the aroma of the cider, and you won't get much clove spice because apples lack the precursor needed for the yeast to produce it.

My concern with the general concept of a sour cider is that the sourness will seem too aggressive since cider ends up so dry. That said, because cider is so easily fermented there may not be that much residual sugar for the bugs to eat. Sour beers are generally brewed to have lots of complex sugars that the primary yeast strain can't ferment, but cider can easily get down close to 1.000 even with a regular ale yeast. We'll see how it turns out, if it ends up too sour I may blend it with a malty ale for further aging (New Glarus Apple Ale is the only similar beer I am aware of).


I probably won't really know the results of this one until next fall, but I'd love to know if anyone out there has tried something similar.

The Bottle: Wine Barrel Flanders Red

Saturday the DC Barrel Guys got together to bottle our first sour beer, the Wine Barrel Flanders Red we racked into the barrel last November. The year had been good to the beer, after a brief period of sickness (the pediococcus getting moving) the beer has developed a bright acidity, and huge fruit (cherry) and oak complexities (look for a full review in a couple weeks once it carbonates.) Of course I forgot to bring my camera, so I don't have any pictures from the actual event, but I am sure Dan (City Brewer) and Nathan (Des Jardin) will post some pictures and their own takes on the day soon.

We debated the amount of priming sugar for a long time. Originally we were working on the assumption that the beer would be wine flat, based on this quote from Vinnie Cilurzo (BYO Jan/Feb 2008) "Remember that if you are bottle conditioning, you'll need to add more sugar than normal, probably 1 cup of sugar per 5 gallons (19 L). This is because the beer has lost all of its CO2 during barrel aging. It is as still as wine when it comes out of the barrel." The beer tasted a bit carbonated though, so we decided to hold back on the sugar a bit, 149 g of corn sugar per 4 gallon batch was decided to be a good compromise (adding 2.45 volumes of CO2 to the beer). We also added some rehydrated champagne yeast to each bucket (20 grams total) to ensure timely bottle conditioning.

We needed to find a way to get the beer out of the bottom of the barrel without lifting it or disturbing the sediment. Noah rigged up his march pump with a 90 degree turned pickup in the barrel. It worked perfectly as we pumped 33.2 lbs of beer into bottling buckets set on Tim's postal scale (easier to divide the beer for priming purposes than volume.) This was the step I was most concerned about, but it gave us no problems.

Noah (Redcar) took a time-lapse video of the barrel emptying/filling, one shot every 15 seconds. Not that you'll be able to pick up too much of our technique, but it is a fun 1:43 (not sure who we should blame for the bucket halfway through).



Overall the day was surprisingly quick and smooth. With that many people we were able to run three bottling stations at a time. From the time we started emptying the barrels to the time all the beer was in (~350) bottles and 20 gallons in carboys and kegs it only took 2.5 hours (and that was with some delicious beer samples from our BrewLocal tour of Bullfrog Brewing and Selin's Grove, and some excellent fried eggplant pizza from Pete's Apizza in Columbia Heights where Dan works).

I took half of my 8 gallon share in bottles (everyone who took bottles got 1.5 cases of 12 oz bottles, and six 22 bombers). Not a bad return on a 5 gallon investment.


I also took a six-pack of my share and added some bottle hops. I was inspired by a bottle of El Rojo Diablo from Bullfrog (a sour red dry-hopped with Amarillo). I decided to go with a combination of Amarillo, Simcoe, and homegrown Cascade (about one hop cone of each), I thought the citrusy character would match well with the acidity (I was really right - tasting). New Belgium does something similar as well with a pale sour beer to make La Terroir.


My other 4 gallons was racked onto 2 lbs of sour cherries I bought at the local farmers market and froze back in July. In addition to boosting the cherry character of the base beer it should renew fermentation, boosting the funk and acidity. I'll probably let it age another 3-4 months before putting it into bottles.


After three hours of bottling we still had the task of racking the next beer (Sour Single) into the same barrel. We did not clean out the barrel, but we did suck out all but ~1 qrt of the slurry (for use in other batches). 20 gallons of the Single had stopped fermenting around 1.020, 10 had just been brewed in the last 36 hours, and 25 gallons had fermented out completely 1.006-1.012. The resulting blend was around 1.030, lots of residual sweetness, but that will be gone pretty quickly (the airlock was starting to bubble just a couple hours after we finished). This beer will probably stay in the barrel until this time next year.

The Barrel Aged Wee Heavy is also coming along nicely. It has a nice bold acidity, but without much funk. It has a solid barrel/oak character, but not too much bourbon character. Hopefully it will be ready to bottle in the next few months, an Imperial Porter is the leading candidate for the next beer into that barrel.

This one turned out great, first tasting.

The cherry half was infused with Sorachi Ace and lime peel and entered into the Iron Mug.

The cherry half turned out well, huge acidity, balanced cherry contribution.

Weizenbock Recipe

Fermenting WeizenbockWith a yeast cake of White Labs 300, Hefeweizen Ale Yeast, left over from my Extract Hefeweizen sitting in my fridge I wanted to brew something with it. I considered doing a Dunkleweizen (Dark German Wheat) or a Roggenbier (German Rye), but with cold winter weather approaching I decided to step it up and do to my first Weizenbock. This is a rich, generally dark, wheat ale typified by Schneider Aventinus. Rather than having the big banana character of a Hefeweizen, Weizenbock has a more complex fruit character with banana mingled with dark fruit and a firm Bock-ish Munich maltiness.

I decided to go with a pretty moderate gravity for this batch (1.075), I wanted it to be big and flavorful, but not so big that I couldn't enjoy a pint on a weeknight. In general I like beers in this middle range (6.5%-8.5% ABV) sitting between session ales and the big monster alcohol bombs.

For most of the malt I went with a pretty standard mix of dark Munich, Vienna, and wheat malt. Instead of adding pilsener malt for the rest of the base I added some Marris Otter, which will add a bit more depth of maltiness that I don't get from pils in such a rich beer. I also added some Simpsons Extra Dark Crystal which added a wonderful character to the lagered Wheat Triplebock I brewed last fall. It adds a nice combination of dark fruit with just a hint of coffee, as well as some nice color. I went a bit lighter on it than I did in the Triplebock because this is a lighter beer that I want to be easier drinking.

I kept the fermentation pretty cool (58-60 ambient) to ensure that this beer turns out pretty moderate in terms of alcohol and ester character. After fermentation finished I gave the beer some time at 45 to allow the yeast to drop out and the flavors to meld.

Yeast cake saved from extract weizen when it was racked to the keg 9/25/09

Brewed 10/03/09 By myself.

Fly sparge. Collected 6 gallons of 1.055 wort. Added 1/4 tsp of CaCl to the runoff to drop the pH and ensure a good hot break.

1 Year old hop pellets reduced from 3.5% AA.

Cooled down to ~70, put into 58 degree fridge.


Pitched after ~4 hours with 60 seconds of pure O2. Good fermentation by 8 hours.

Good hard fermentation, a bit of blowoff after 2-3 days.

10/05/09 Upped temp to 60 to help it finish.

10/14/09 Dropped temp to 45 to help clear.

10/25/09 Still pretty hazy, balanced fruit character, some caramel. Down to 1.016 (79% AA, 7.8% ABV)

10/27/09 Racked to a three gallon secondary. Took out of fridge, left at basement temp.  Extra beer racked into a growler and primed.

11/29/09 Bottled with 2 5/8 cane sugar. The growler was very tasty a few weeks back shared with a few friends, so I have high hopes for this one.

2/7/10 First tasting, turned out very well, good complex blend of flavors and aromas and solid drinkability.

4/28/10 Scored a 32.5 at the 2010 NHC.  Judges thought it was old/oxidized, a character I don't really get.

Adam Clone First Tasting

With the cold weather arriving in DC early (I already saw my first snow of the year a couple days ago in Williamsport PA) I thought it was time to dip into my stash of big beers for this review. Six months ago I brewed a clone of Hair of the Dog Adam, a terrific, but uncategorizable dark ale with a kick of peat smoked malt. For more details on the recipe and beer check out my initial post on the brew.

The carbonation still hasn't shown up in this one, but it has enough residual sweetness and body to still be tasty. That is something my liquor spiked barleywine (which finished a few points lower) was not able to handle (incidentally the carbonation is finally coming along on that one).

Adam Clone - 10/19/09

Appearance – Dark, dark, dark brown... ok black. Clear when held at a steep enough angle to gaze through the otherwise opaque body. Thin, coarse, tan head. Despite the lack of carbonation it has decent head retention.

Smell – A combination of coffee and earthy peat malt take the lead. The smoked character is very well integrated into the rich caramel malt. Certainly some alcohol, but I wouldn't call it hot. Nice dark fruit character as well, prunes in particular.

Taste – Well balanced, thick maltiness balanced by bitterness from both the hops and the dark malt/smoke. The smoke and coffee/chocolate/biscuit malt notes blend perfectly. The hops are not as potent as the 65 IBUs might suggest, but that may be a result of the clean Galena and Super Styrians used for bittering. Not much hop aroma is left from the Tettnanger addition at 10 minutes. A clean ethanol bite, not too surprising from a ~10% ABV at cellar temp ~60 F.

Mouthfeel – Rich and full, honestly it has enough body to hold up without carbonation, but it still would be better with some fizz.

Drinkability & Notes – I'm really pleased with this one, but at 5 months in the bottle it will probably take some additional yeast to get any carbonation. I think the original Adam is a smokier beer, so if you are looking for a true clone I would up the amount to what was originally called for, but it is great as is. Not much I would change if I brewed it again, but the sample of Cherry Adam from the Wood I had a month back was enough to convince me that cherries (subtle) and bourbon soaked oak would be a good addition to this one.

Extract Weizen and Single Tasting

After a few weeks under pressure in the kegs my first two "return to extract brewing" experiments are ready to taste. Both of them turned out well, clean (no mythical extract twang) and surprisingly pale.

If you are an all-grain brewer I'd suggest giving an extract batch a shot if you are short on time some day. You may not have quite as much control as you are used to, and it may cost a bit extract, but it can certainly produce excellent results.

Extract Hefeweizen

Appearance – Slightly hazy golden-orange body. Certainly lighter in color than most people think an extract beer can be, and certainly no darker than my decocted all-grain hefeweizen (if anything it might be a bit lighter). Nice looking creamy white head, with good retention, but not much lacing.

Smell – Pretty mellow aroma, a slight hint of banana and some spice. It is lacking the bready/yeasty character that great hefes have, but that may be more a result of the kegging (and the lack of yeast) rather than the extract. As the beer warms it begins to show a hint of sulfur, hopefully that will pass with a bit more age.

Taste – The flavor is similar to the aroma, very subdued. The ester character is only banana and a pretty restrained one at that. It is supported by some classic clove notes (not as much as I like though, the ferulic acid rest certainly seems to have boosted the clove in the all-grain compared to this). Pretty dry with just a touch of hop character to balance the slight sweetness. It has a slight carbonic bite to it from the high carbonation, which adds a touch of acidity to the beer.

Mouthfeel – Moderate-thin body with a nice firm carbonation. As it warms and the carbonation beings to wane it comes across as thin, but fresh out of the tap it is just refreshing.

Drinkability & Notes – A solid beer, but it doesn't have the complexity that my all-grain version did. I would like to try this recipe again to a bit higher gravity and with Wyeast 3068 (rather than White Labs 300) which seemed to give me a more complex ester profile.

Extract Single

Appearance – Another really great creamy head with great retention, and nice coating lacing. The body is a shade darker (probably due to the liquid extract) and a bit hazier (probably because it is a week younger than the hefe).

Smell – Great complex nose with notes of pepper, and lemon. There is even some breadiness from the malt, or maybe that is just a bit of suspended yeast.

Taste – Great complex phenol character, clove, cinnamon, and pepper. Almost saison like, but not quite that dry. There are some esters as well, pear with a light touch of banana, but the low fermentation temperature kept them moderate. Good balance with just a touch of herbal hop, not as much as I expected from an ounce of hallertau at 5 minutes. It could be a bit drier, but I wouldn't call it sweet.

Mouthfeel – A bit fuller than the hefe, with moderate carbonation. Could be a touch thinner/crisper, but it is very drinkable as is.

Drinkability & Notes – One of the better non-sour Belgian beers I have made, good balance with plenty of complexity. I'll be interested to see where this one goes with a bit more age, hopefully it doesn't clean up too much in the keg. I'll certainly be brewing this one again, although I might boost the sugar to help it finish a bit drier.
