Belgian Sugar Experiment: Round 2

Since I did my first split batch sugar experiment last summer I've been wanting to do it again.

I tried to keep the recipe as similar as possible, due to convenience I changed the basemalt to French Pils since I had a sack of it, Wyeast 3787 because my local homebrew shop doesn't carry White Labs (WL530 and WY3787 are both reportedly the Westmalle strain), I also used melanoidin malt instead of aromatic (very similar extra dark Munich type malts from different maltsters).

I also made a change in the procedure, last time after the boil I immediately split the batch and did the primary fermentation in separate jugs. This created a terrible mess, so this time I did the primary in a 6 gallon fermenter and then added the sugars to the individual jugs for secondary fermentation. This may increase the impact of the various sugars because they will not be subjected to the violent primary fermentation.

Notes
-----
Brewed 10/08/07 with James

Added 4 grams CaCl to 4 gallons of mash water to get the calcium up to make sure mash was around the right pH (measured around 5.4 at room temp, 5.1 at mash temp)

Collected 6.25 gallons of 1.045 runnings, 4.25 gallons post boil topped up with a jug of Poland Springs water

Placed the fermenter in 60 degree freezer for 5 hours, topped up to just under 5 gallons with 3 quarts of Poland Springs water. Gave 1 minute pure O2, then pitched a fresh, inflated smack pack of yeast. Fridge adjusted to 64 degrees.

Took about 24 hours to get going, but after that it had a vigorous fermentation.

After 48 hours of active fermentation I bumped the ambient temp up to 70 to prevent the yeast from "crashing" and to encourage the formation of esters.

10/14/07
Took 3.5 oz of each sugar and brought it to a boil with 3.5 oz of water. I then mixed each sugar with a little less than a gallon of beer in a 4 liter jug for secondary fermentation.
1. Agave (Used to make Mezcal/Tequila)
2. Lyle's Golden Syrup (Common in English baking)
3. Granulated Date Sugar (Dehydrated dates, ground up) Rehydrated it got really thick and tasted like pureed dates
4. Homemade Candi Sugar (plain white sugar with regulated temp rise)
5. Gur/Jaggery (An Indian sugar made from either Palm Sugar or Cane Sugar, not sure which mine is, but I think it is palm.)

By the next day it appeared that all of the batches were fermenting again, with the date sugar batch seeming the most active.

Bottled 10/28/07
Aiming for 2.8 volumes of CO2 about 22 grams of corn sugar per batch. Got a six pack and a bomber of most of them.

Final Gravities:
Agave - 1.006
Homemade Candi Syrup - 1.006 (It's fermentable Woohoo!!)
Gur - 1.007
Lyle's - 1.006
Date Sugar - 1.005

Full tasting in late December.

Are you afraid of brettanomyces?

Apparently not most of the people who vote for polls on my blog, the final tally was:

If you answered:

Yes (30 people, 28%)
-Brett is nothing to fear (at least as a home brewer), but you are right to be weary as it can certainly spread from one beer to another if your sanitation and cleaning are lackluster.

No (66 people, 63%)
-Good work on selecting the correct answer! Add 5 points to your score.

What??? (8 people, 7%)
-Have you been paying attention at all! Brettanomyces (Brett, Bret, Bretta) is a wild yeast used in the production of many sour and funky beers. Some people (particularly wineries and most commercial breweries) fear it as the rampant madman of the fermentation world, capable of tainting their precious "pure" strain fermented beverages. While Brett can turn a delicious beer into a thin and funky mess, good sanitation practices will prevent this from happening.

Pumpkin Kegging

Inspired by recent talk of mashing and fermenting in a pumpkin I decided instead to take the easy route and serve some commercial pumpkin ale out of a pumpkin.

I took a standard pumpkin, cut the top out scraped out the "guts" like I was getting ready to carve it. I cut a small circle in one side of the pumpkin and then screwed in the spigot from my bottling bucket, it took some extra scarping to get the nut screwed on the inside. I then chilled the pumpkin for a few hours in the refrigerator. I filled the pumpkin with a selection of pumpkin beers (Post Road, Dogfish Head, Saranac, Buffalo Bills, and Smuttynose). Amazingly it worked without leaking and the blend of beers actually tasted pretty good.

I really don't think serving from the pumpkin added much flavor, but it really enhanced the appeal of the beer to the "non-beer" people at the party. The key was to get both the beer and the pumpkin as cold as possible so that the maximum amount of carbonation remained in the beer.

As a plus when the beer was finished we got to carve the pumpkin. I gouged out the eyes and nose and a more artistically gifted friend carved the mustache.

Cider 2006

With fall and apple season upon us once again I felt it was time to put up a cider post. Last Fall I brewed a very simple hard cider. I threw the recipe together spur of the moment before heading off to Denver for a few weeks. I added some malt extract to the cider to give it some residual sweetness and some yeast nutrient to aid the yeast. I used a packet of dried champagne yeast which makes for a very clean cider, but one that is pretty low in character.

I have a new batch fermenting now, that is a bit less traditional, but should have a bit more interesting flavor and hopefully won't take so long to get good.

My 1st Cider


Recipe Specifics
----------------
Batch Size (Gal): 2.00
Total Grain (Lbs): 16.75
Anticipated OG: 1.055
Anticipated SRM: 6.9

Cider/Extract
---------------
16.50 lbs. (2 gallons) Cider
0.25 lbs. Generic DME - Light

Yeast
-----
EC-118 (Champagne yeast)

Notes
-----
Made 10/31/06 by myself

Heated a cup of juice with 1 cup DME and .5 tsp yeast nutrient.

Cider was from Whole foods, pasteurized but no preservatives. 1/2 packed of yeast added straight into fermenter.

11/18/06 transferred to two 1 gallon jugs and stuck them in the fridge. 1.010, tasted pretty good with a sour twang at the end.

11/24/06 Bottled aiming for 2.5 volumes of CO2.

1st Tasting 10/17/07

Aroma
- Sweet apples soaked in white wine. There is a hint of sulfur as well, but it is just a background note like is often present in many white wines (not sure if that is the only reason I thin.

Appearance -Nearly opaque it is so cloudy because I didn't use finings or pectic enzyme. The cider is yellow-tan with a thin white head that has surprisingly good retention. Personally I don't mind a hazy beverage, but if you do some pectic enzyme is important because it breaks up the pectin (the same stuff that is responsible for the thickening jams and jelly).

Taste - Tangy with a light apple flavor. Some apple skin as well. It still tastes pretty fresh, with no oxidation or other off-flavors apparent. It strikes a good balance between sweetness, dryness and acidity. However, the flavor is very mild to the point of being bland.

Mouthfeel - Prickly carbonation and a bit thin. There is a light tannic roughness on the tongue as well.

Drinkability/Notes - Finally getting pretty good after almost a year, but it is still rather bland. As time has passed the apple flavors have come more to the front which is nice, in fact I think this is the most I have enjoyed a bottle of this one so far. It really didn't turn out badly for a batch that I threw together on a whim and fermented while out of the state.

Homemade Candi Syrup

After talking to Brian Mercer the importer of the amazing Dark Candi Syrup and making multiple attempts to make my own at home, I think I have come up with something that will hopefully be tasty, but doesn't approach the color contribution. I have included this one in my second Belgian Sugar Experiment, so I'll have a more accurate impression of the flavor and fermentability by early November.

Steps:

1. Take 1 lb of plain white sugar and mix it with 3 cups of water in a heavy bottomed saucepan.

2. Stir to dissolve over medium heat (if the heat is too low there is a chance that the sugar will crystallize on you, so make sure you have rapid bubbling)

3. Monitor the temperature until it hits 285 degrees then add a tablespoon of water.

4. Adjust the heat until it is hot enough that you get bubbles all over the surface of the syrup, but not so hot that the bubbles build way up the pan.

5. Repeat this as needed not letting the syrup get above 285 (This will be a lot easier if you have a thermometer with an alarm). During this process you will smell an amazing range of aromas starting with butter, then moving through rummy and finally to sort of a roasted raisin thing.

6. Once the syrup takes on a nice dark color add 1/3 cup of water and let cool.

What is the point of all this?

Boiling sucrose for awhile in water causes some of the disaccharide sucrose molecules to split (invert) into the monosaccharides glucose and fructose. Some recipes call for the inclusion of an acid to aid the inversion process, but the importer assured me that the only ingredient in his product is refined beet sugar (sucrose).

Once some of the sugar is inverted holding it at around 285 presumably allows some of the newly created fructose to caramelize (caramelization temp of 220), while the more robust sugar molecules glucose (caramelization temp of 300) and sucrose (caramelization temp of 340) remain intact and more importantly fermentable.

The final addition of water allows the finished sugar to remain liquid at room temperature, making it much easier to add to a beer than lumps of solid sugar.

Log:
1st attempt: 1 lb sugar, 1 pint water, 1 tsp 10% phosphoric acid, 45 minutes @ 260-275
Result: Way too sour, apparently I used way too much acid.

2nd attempt: 1 lb sugar, 1 pint water, 1 gram acid blend, 150 minutes @ 260-275
Result: The syrup turned out a bit thin and the flavor just seemed flat.

3rd attempt: 1 lb sugar, 1 pint water, 180 minutes @ 260-275 (accidentally let it get up to 310 in the middle of cooking)
Result: Good flavor, but a bit too much char probably from the high temp.

4th attempt: 1 lb sugar, 3 cups water, 180 minutes @ 260-285
Result: Good flavor with less burnt notes than attempt 3, but also not as dark.

I used my 4th attempt in my second sugar experiment. I am happy to report that the portion of the experiment with the homemade candi sugar got just as dry as the other portions. The beer tasted good at bottling time, but it will be a few weeks before I can give a real report on the success or failure of this technique.

Here is a short little video of attempts two (left) and three (right) boiling. You can see just how much the sugar bubbles can build up.

My Homebrew Club




Recently I've had a bunch of people ask me if I'm a member of a homebrew club. As a matter of fact I've been a member of BURP for almost a year now. It is a great club with loads of members who are amazing brewers and there is at least one person who can answer any question whether it be about how to treat you water or how to use a wine barrel. Every meeting I go to I feel like I make a new friend and learn something new about brewing.


The club seems to be undergoing an infusion of new brewers, every meeting there seems to be three new people coming for their first meeting. So don't feel like everyone will know everyone else and you won't know anyone else when you show up.


If you live in the metro DC area stop by a meeting and say hello, but first send me an email so I can tell you who to look for. If you aren't local find a club near you, its the best way to meet local brewers and get to taste some amazing beer.
