Hoppy-Spicy Rye Golden Ale

I have nothing against brewing to-style. You can make magnificent and delicious beers by using ingredients from a single region with the goal of a classic balance. That isn't who I am as a brewer though. The recipe for Sapwood Cellars' False Dragon is the sort that I'm passionate about. We selected ingredients from all over the globe to create a flavors and aromas that aren't authentic to any one tradition. What I wanted was an earthy-crisp malt flavor, a white-winey hop aroma (for less money than Nelson Sauvin), and a subtle spicy and fruity-boost from the yeast without getting in the way. That required malts from America and England, hops from America and Germany, and yeast from England and Belgium.

I'd been experimenting with the hop bill for a few months to get the ratio right, and eventually settled on 2:1 in favor of Mosaic. After a few test batches, Scott and I have embraced adding less expensive hops on the hot-side (Cascade, Columbus, Chinook, Centennial etc.) with the more aromatic and expensive varieties saved for the fermentor. I wanted to split my homebrewed test batch to compare S-04 alone against S-04 with 8% T-58. As with Ziparillo, dry yeast is cost-effective especially if you can't repitch thanks to early or mid-fermentation dry hopping. Belgian strains have shown heightened biotranformation abilities is some studies, so it seemed like a good candidate for double dry-hopping.

For the 10 bbl batch we decided to fill-in a gap in our range when the first batch of Rings of Light (our Citra dry-hopped hazy pale ale) came in under-alcohol at 4.8% thanks to lower-than-expected efficiency. In effect the two recipes switched places with False Dragon becoming the "bigger" pale ale at 5.3% rather than the 4.7% of the test batch. Our attenuation has been lower than expected across the board for our first five batches too. We're still trying to figure out the cause given it has happened with multiple yeast strains - likely mash related. Luckily our hop flavor and aroma have both been wildly better than either Scott or I have been able to achieve at home, I'm sure surface-to-volume ratio plays a role.

Your first chance to try this beer is at the Sapwood Cellars grand opening, Noon-10 PM on Saturday 9/29. We'll be open Thursday-Friday 4-10 PM and Saturdays Noon-10 PM from then on. Stop in, drink a beer, say hello!

The name False Dragon come from The Wheel of Time series of books by Robert Jordan. My commute has gone from 20 minutes on the subway to my desk job to ~40 minutes by car. Audio books are my new friend. While I'm sure brewing podcasts would be a more productive use of my time, after 12 hours brewing it is nice to have a little escapism.

False Dragon S-04

Smell – Had to go for a fresh pour after taking photos as it had gone a hint skunky after five minutes in the sun… Nose is a fresh “true” hop aroma to the Mosaic and Hallertau Blanc. White wine, but also some blueberry and green/herbaceous. Certainly Nelson-reminiscent, but a unique character as well.

Appearance – Pale yellow, pleasantly hazy. Good head and lacing, but the foam itself feels airy on the tongue. I guess I’ve gotten used (and miss) to the contribution of chit malt.

Taste – A firm amount of bitterness in the finish, but it doesn’t linger. Light and bright with the tropical-fruity hops starring. Rye doesn’t really make a strong showing, although I’ve always found it more subtle than some others taste.

Mouthfeel – The rye helps prevent it from being watery, but it is a summery pale ale. Glad we ended up a little higher OG/FG on the big batch. Medium carbonation, nice for a lighter beer.

Drinkability & Notes – A pleasant session IPA. The Mosaic and Hallertau Blanc work better together than apart.

Changes for Next Time – 10% chit in place of the base malt wouldn’t hurt. Could certainly up the rye too for a bigger contribution.

S-04 and T-58

Smell – More rounded, less grassy-distinct hop aroma. Tropical, juicy, inviting. The green flavors are now more honeydew melon. Impossible to say how much of that is actual hop chemical reaction, or synergistic between the hops and esters. Lightly bready.

Appearance – Looks similar in terms of head, color, and clarity.

Taste – Lower perceived bitterness. A more saturated/integrated fruity hop flavor. Passionfruit especially. I think this is the more approachable and interesting beer, and distinct from the other English-only fermentation we are doing (using RVA Manchester). Slightly elevated phenols, but much lower than from the WB-06 in Ziparillo.

Mouthfeel – Slightly creamier (perhaps just the lower perceived bitterness?), identical carbonation.

Drinkability & Notes – I was able to identify these pretty easily in a blind tasting. It is amazing how much impact such a small amount of yeast can make.

Changes for Next Time – We decided to back down the T-58 4.4% of the blend to allow a bit more of that fresh/distinct hop character through. Other than the higher gravity, the recipe was otherwise unchanged for the 315 gallon batch! We’ll probably up the rye for batch #2 now that we know we can handle higher percentages of high beta-glucan huskless grains.

I, Beer: What Goes Into Brewing

I, Pencil is a classic economics essay from 1958 by Leonard Read about the complexity of making a pencil. The iconic yellow #2 seems so simple, yet no one person could make it on their own (e.g., harvest the rubber, synthesis the polymers and pigments for the eraser, create the yellow paint, precisely cut the wood and graphite, mine and forge the metal band etc. ). The global economy doesn't have any person or group coordinating all of this activity, but to earn money people and companies fill niches, specialize, and compete to buy and sell in ways that creates things of immense complexity requiring the sum work of hundreds of people across continents so you can buy a pencil for $.25. This video gives a more hands-on view of what it takes to make a chicken sandwich when you don't buy anything from a supermarket.

It is tempting to say that beer isn’t like that. After all, each all-grain batch starts with the four basic ingredients and we do the rest… sure it would be a challenge to grow and malt barley, harvest and dry hops, isolate/propagate wild yeast, and haul water from a local stream, but what vessels would you use to boil/ferment? What about sanitizer, minerals, clarifiers, compressed CO2?

What follows is a high-level overview of what is required to brew a single batch of beer at Sapwood Cellars. Obviously, you could keep digging deeper into each one of these, peeling back layer-after-layer to the inputs of each input (e.g., the shoes that the hop harvester was wearing). I’ll arbitrarily stop where I lose interest. Needless to say though, the work of thousands in not millions of people goes into each of our batches. Scott and I just get the credit (or blame) because we're the ones at the end of the chain!

Ingredients

Water

Our water comes from Liberty Reservoir. From there it goes to Baltimore’s Ashburton water treatment plant. Baltibrew posted a nice series on the Baltimore water system. Luckily for us the existing minerals are mostly beneficial to the character of our beer. The carbonate is a bit higher than we’d like, but not by enough to require the waste of reverse osmosis.

Once pipes take it to the brewery it passes through a carbon filter to remove chlorine, and then an on-demand hot water heater. The fuel is natural gas piped into the brewery by BG&E (by way of fracking or older methods, and then refining). From there the water travels through a hose to our hot liquor tank where an electric element allows us to adjust the temperature. The electricity comes from a mix of fossil fuels, nuclear, and ~5% renewables.

To adjust the mineral content of the water, we add calcium chloride (from limestone-hydrochloric acid reaction or natural brine concentration) and calcium sulfate (harvested and refined from gypsum rock deposits). In addition, we add 75% phosphoric acid to adjust the pH of the water. Phosphoric acid is usually produced by combustion, hydration, and demisted from three ingredients: phosphorus, air, and water.

Grains

The grain we mash is a mixture of barley, wheat, oats, and rye depending on the beer. These are grown primarily on farms in North America and Europe. It is then soaked, sprouted, dried, and kilned by a maltster. The precise equipment required varies by malt and producer. In some cases it is a large industrial operation, in others the malt is still manually turned. The bulk of our base malt is Rahr brewer’s 2-row from Minnesota, but in our first order we also had sacks from Briess, Chateau, Simpsons, Crisp, Best etc. Most of the unmalted flaked grains (steamed and rolled to gelatinize their starches) are from Grain Millers.

We decided to hold-off on buying our own mill, to save the cost at the start… but after a few brews I can say a mill and auger are in our near future. We order our grains from Brewers Supply Group, which pre-mills the grain. We also occasionally add a few sacks to a Maryland Homebrew order from Country Malt.

Once we’re done with the now “spent” grain, they are picked-up by Keith of Porch View Farms. He feeds it to his animals as most of the carbohydrates are extracted into the wort, but proteins remain.

Hops

Our hops are grown throughout the higher latitudes of the globe, primarily the Pacific Northwest of the United States, but also Australia, Germany, and Czech Republic. The hops are first stripped from their bines, dried in an oast, and then baled. After selection, various lots are blended to create a consistent product and the hops are pulverized and pelletized. They are then vacuum-packed in mylar and stored cold to preserve their aromatics. Our hops primarily came from Hop Havoc, but we’re working on getting contracts for the upcoming harvest.

Yeast

Most of the yeast we’re using are the decedents of yeast that have been fermenting beer for hundreds or thousands of years. A couple hundred years ago their ancestors were part of a mixed-culture at breweries in England and Belgium, only to be lucky (and talented) enough to be isolated as a pure culture that gained success. Our Saccharomyces cerevisiae so far has come from RVA, Fermentis, and Lallemand for our “clean” beers. These needed to be isolated, propagated, and in some cases dried.

The sour and wild beers are too complex to track. They come from labs, bottle dregs, and a house culture. They may have come via a barrel, the breeze, an insect, or any number of other vectors into a brewery or labs. For example the Hanseniaspora vineae we are fermenting a hoppy sour for Denizen's Make It Funky festival came from Wild Pitch Yeast which isolated it from tree bark.

Fruit

We don’t have any beers far enough along for fruit, but we’re planning to source as much of it as we can directly from local farms and orchards. Most fruit is at its best when it is picked ripe and used quickly. I'm sure we'll use dried fruit, aseptic purees, juices, and freeze-dried fruits depending on quality, availability, and desired results as well. The first batch will probably be a tart saison on grape pumace (the pressed skins) from a local natural winery.

Other Consumables

Gas

Carbon dioxide is usually produced as a byproduct of some other activity (e.g., hydrocarbon processing). Our CO2 is stored in a 750 lb tank in a liquid state. We use it to carbonate and serve beer. It isn't economical at our scale to recapture the CO2 released by fermentation. Our supplier is Robert’s Oxygen.

As the air on Earth is 70% nitrogen it is usually concentrated with the use of a nitrogen generator. These rely on a membrane that allows nitrogen through. We need nitrogen to help push the beer through the long-lines from our walk-in to the tasting room (pure CO2 would lead to over-carbonation at those pressures). As the second most abundant gas in the atmosphere, oxygen generation uses similar technologies. We pump .5L/minute into the wort as it exits the heat exchanger, the yeast quickly uses it to create sterols for healthy cell walls when they bud. We get these two gases in large cylinders that are swapped out.

Chemicals

We need cleaners like caustic (sodium hydroxide) to remove organic deposits, and a phosphoric-nitric acid blend to remove inorganic beer stone and passivate the stainless steel. For sanitation we use iodophor for fittings in buckets, and peracetic acid for the tanks. These are made in a variety of industrial processes that I’m totally unaware of. Our chemicals are provided by Zep/AFCO.

Clarifier

Whirlfloc G helps proteins clump together in the last 15 minutes of the boil to be left behind. It is derived from Irish moss (seaweed) that is dried and granulated. As a vegan brewery, no gelatin or isinglass for us.

Barrels

Oak barrels start as oak trees. They are processed into planks, and then purchased by a cooperage which dries (either in a kiln or naturally). They are then assembled into barrels with metal hops, toasted, and sealed. From there they go to vineyards and distilleries that age their products in them. Beer is best in barrels that have already lost much of their oak character, so we buy them from other producers. A small amount of the wine or spirit is still present in the wood, providing a moderate contribution to the first batch, diminishing with each additional batch.

Equipment

The stainless steal for the vast majority of our equipment comes from China. Our brewhouse was constructed by Forgeworks in Colorado. Our fermentors and bright tank from Apex and DME in China. Our keg washer from Colorado Brewing.

The cooling of the fermentors is accomplished by a glycol chiller from G&D Chillers in Oregon. The ethylene glycol itself comes from ethylene and oxygen. The chiller also assists chilling the wort with our two-stage Thermaline heat exchanger (primarily more stainless steel). The copper pipes that carry the glycol are insulated with Armaflex. The flow of the glycol to individual tanks is controlled by electronic temperature sensors and solenoid valves.

Other equipment includes hydrometer, refractometer, pH meter, hoses, gaskets, and all manner of other valves and fittings.

For the space itself there was already plenty of concrete, bricks and metal. We hired Kolb Electric and B&B Pipefitters to do the installation of the bulk of the wires, pipes, and connections.

There is also everything that goes into serving a beer once it is ready. Kegs (Corny kegs for the sours and infusions, sanke for the standard clean beers), stainless steel fittings, beer lines, glasses (including the printed logo and the glasswasher) etc.

What’s the Point?

I don’t really have one. To me it is just remarkable how much of the complexity of brewing a batch of beer is now hidden in the inputs. I know how to brew beer at my house or a brewery, but if you put me out in the woods even with all the ingredients, I couldn’t brew a batch. Thinking about what is required for each batch makes me appreciate how nice it is to live in a time when I can brew beer as simply as going online and ordering the equipment and ingredients I want. It also shows me how much I still have to learn about making beer.

At the same time, it means that beers everywhere are mostly separated by the choices the brewer makes rather than the availability of ingredients. The exchange of information accelerated by the Internet. I hope there continue to be regional variations, specialties, and preferences. Traveling isn't as exciting when everyone brews NEIPA and pastry stouts.
