Kitchen Brewing: Making Brewer's Invert Syrup for Tawny's Burning Calamity Barleywine

Back in 2012, I did a post on making your own Candi Sugar for Belgian beers. Nine years later, it's time to make Brewer's Invert Syrup for British beers.

While these syrups are available commercially, they're tough to find in the US, as there are only a handful of homebrew shops that carry them. They're also not exactly cheap, so why not make your own?

The sugar I prefer to use for making Invert Syrup is Turbinado. Complexity is what I want from these syrups, and I feel that Turbinado, as well as other raw sugars, create more complex flavors than plain white table sugar does. However, table sugar works just fine. 

Here's the basic procedure for making one pound of Invert Syrup:

  1. Mix one pound of sugar with approximately 1 cup of water to make a thick syrup.
  2. Over Medium heat, gently stir the liquid until the sugar is dissolved. 
  3. Add 1/4tsp of Cream of Tartar. You can optionally add roughly 2Tbsp of Lyle's Golden Syrup at this step to help avoid crystalizing your syrup.
  4. Maintain Medium heat and slowly bring the mixture to a boil. 
  5. Keep boiling, and when the temperature reaches 236F(114C), you should have either a clear to slightly golden (table sugar), or a light amber (Turbinado or other raw cane sugar) syrup. 
  6. At this point, you can either stop, or continue heating. If you used raw sugar, the initial syrup will be roughly Invert Syrup #1.
  7. If you choose to keep going, Invert Syrup #2 should be reached around 260F(127C), and #3 at 280F(138C). I tend to stop at #3, as getting past 300F(149C) can get you into the territory of accidentally making hard candy.
  8. When the syrup is done, you can either add it straight to the brew kettle (my favorite), or put it in a mason jar. If you jar the syrup, store it somewhere cool.

The syrup for the beer below is an amber one that's in the ballpark of Invert Syrup #2.

My syrup is going into an English Barleywine that's a ramped up version of an Old Ale I brewed a few years ago. That beer was very loosely based on Fuller's 1845. What I have here is essentially a beer that's been inspired by a beer that was inspired by a beer. Seems simple enough.

Because beers like this can develop Port-like qualities as they age, I'm speeding the process up by introducing an oak spiral dipped in Tawny Port that will be added six weeks before bottling. I'm pretty confident it will do what I intend it to. I'll find out if that's the case in roughly six months.

As a final step, I'm bottle conditioning my beer using 6oz of Lyle's Golden Syrup, along with fresh White Labs WLP002 yeast (a.k.a. the Fuller's strain).

In the Fermentor: Bohemian Kölsch

Being a brewer on a budget, I don't have an extra fridge to lager in. That poses a bit of a problem, because I love a good Pilsener on a hot Summer day. To my palate, the closest style to Pilsener in the ale department is a German Kölsch . To that end, I've wedded a Bohemian Pilsener influenced recipe with a Kölsch yeast strain to create my Bohemian Kölsch pseudo-lager. I realize that the finished product won't be as clean, crisp and clear as a traditional Pils, but I'm hoping to come close. I want a full five gallons of this beer. Since my kitchen setup isn't conducive to five gallon all-grain batches, I've taken the partial-mash approach. I've also thrown in a bit of Irish Moss toward the end of the boil to help with clarity. Here's the five-gallon recipe: Grains: 3.5 lbs German Pilsener 8 oz Munich 8 oz Crystal 10L 4 oz CaraPils Hops: 1 oz Saaz: First Wort Hopping 0.5 oz Merkur: 60 min 1 oz Saaz: 7 min Extras: 3 lbs Pilsen ...

Out of the Bottle: Porter vs Porter

My Beer My attempt to clone Samuel Smith Taddy Porter is ready to pour. For a change of pace, I've picked up a 4-pack of the real deal to compare and contrast against my efforts. Since I'm not exactly an impartial judge, my girlfriend agreed to blind taste test the two beers side by side in identical, unmarked glasses. I've mixed her notes in with mine. First off, I must say that the beers look remarkably similar. Taddy pours with a slightly larger head, but the beers share the same deep garnet hue. Mine has a bit more carbonation going on. Both beers have good head retention and leave some lace behind. My girlfriend's first comment was that my beer was very similar, but finished quicker than the Samuel Smith. She also noted that the Samuel Smith is slightly more bitter, with more depth of flavor. The first thing I noticed was that my beer has a more roasted edge and is a bit nuttier. It also lacks the unique dark fruit esters that I sense in all of the Samuel...

In the Fermentor: Grodziskie

I'd never even heard of Poland's Grodziskie, until I read about it in a Zymurgy article. Not content to simply read about the beer, I've decided to go ahead and brew one. Besides, who wouldn't want to try a beer made entirely from Smoked Wheat? I've mostly followed the plan laid out in the Zymurgy article. The Mash schedule and hop addition times are as prescribed. However, I don't have easy access to the Lublin hops used in the magazine brew, or the correct yeast strain. In place of the Lublin hops, I've used Polish Sybilla. The beer also calls for a clean ale yeast. I've turned to White Labs ,Dusseldorf Alt yeast to fill the role. In a few weeks my efforts will be rewarded. Here's the five-gallon brew: Grains: 5 lbs Weyermann Oak Smoked Wheat Hops: 0.75 oz Sybilla (6.4% a.a.): 105 min 0.5 oz Sybilla (6.4% a.a.): 30 min Total Boil Time: 120 min Yeast: White Labs WLP036 - Dusseldorf Alt Mash Schedule: Acid Rest: 100F for 30 min ...
