This week I take a look at one of Germany’s most popular beer styles, the light lager known as German Helles. Helles is a traditional German Lager produced primarily in Southern Germany (Bavaria) around Munich. The word “hell” in German can be roughly translated as “pale, light or bright” in English. The History of Helles […]

Any long-time readers may recall my interest in the original Russian Imperial Stouts – brewed in England with four malts (pale, amber, brown, and black) plus caramelized sugar. Fermented with English ale yeast and Brettanomyces. They bear about as much resemblance to modern pastry stouts as the original English-brewed IPAs do to today’s hazies and milkshakes.

Of the many recipes from this blog that we’ve adapted to the big system at Sapwood Cellars (Atomic Apricot, Cherry Wine, Tmavé Pivo, Scottish Stout, Cheater Hops, Saphir Pilsner, Berliner etc.) my Courage RIS-Inspired is probably the one I was most excited about! We closely followed the original recipe from 2007 (which I preferred to the 2016 rebrew). Last summer we released the base beer (Lord Rupert Everton), followed last fall by Lord Rupert Barrelton which had a quick dip in barrels that held Cognac Finish Rye Whiskey from Sagamore Spirits.

After refilling the barrels from kegs of the same base beer, we pitched the same strain of Brett I used for the original, WY5110 Wyeast Brett anomalus. It's been out of production since 2007, but I asked everyone I could think of (starting with Wyeast) and no one had the strain available… French microbiologist Christophe Pinchon to the rescue! We’d already gotten “his” Willner Brett strain second hand for our gose (Salzig). The culture he sent started up quickly and I pitched half of an active 2L starter into each 80 gallon barrel in September… then not much happened. The Brett didn’t produce any CO2 or reduce the gravity over six months. Originally, we planned to bottle the beer once it stabilized, but without any apparent fermentation we decided we were better off kegging the beer as Sir Rupert Barrelton.


Sir Rupert Barrelton

Smell – Loamy, with fresher notes of Tootsie Roll (from the malt) and coconut/vanilla (from the barrel). I really have a hard time figuring out it that earthy note is Brett, or just mild oxidation from time warm in the barrels. The spirit-character is relatively subtle, but is enough to immediately make it clear this isn’t an authentic take.

Appearance – Black with chestnut edges. Pretty good dark brown head. Solid retention.

Taste – Smooth flavor without any sharpness from the roast. The Maris Otter and Amber malt help to fill-in the background of the black malt. Plenty of baking soda prevents the roast-acidity that can cause stouts to become acrid. The dark candi syrup brings a subtle dark fruitiness without being obnoxiously raisin/plum like dark crystal can be.

Mouthfeel – Not as thick as stout drinkers are used to (I’ve seen some stouts finish above 1.080 now… and I used to think Dark Lord’s 1.060+ was absurd)! Low carb, just how I like by big/dark beers.

Drinkability & Notes – It’s a unique beer compared to the other more “modern” stouts we brew. The “reasonable” FG of 1.026 makes it easier to drink than the typically sweeter ones. I like the depth of the combination of barrel-character and malt. The age/Brett give it additional complexity. If you are in Maryland and want to try the beer we'll have it available in crowlers the next month or so.

Changes for Next Time – Maybe it was the alcoholic boost from the barrel that prevented the Brett from doing more? Better to use more neutral barrels, or stainless with oak barrel-alternatives. We refilled the barrels with a riff on my Big Funky Ale and pitched additional microbes. It would be fun to try making our own invert no.4 to replace the dark candi syrup.


Courage RIS Inspired 2016

Smell – Brett (cherry, funk, dusty). The Brett C really covers up the malt almost completely in the nose. Blind I suspect I’d lean towards calling it an Oud Bruin.

Appearance – Black with dark-brown edges. Big tan head that is held up by the carbonation for a few minutes before deflating.

Taste – Stout-ier than the nose, with some cocoa notes. However, the Brett is still the primary flavor. Some nutty (almost peanut brittle) flavors from the malts. Moderate bitterness.

Mouthfeel – Carb is similar to what I remember, higher than I’d prefer. A little thin, although once the carbonation is swirled-down it improves.

Drinkability & Notes – It’s a bit beer with a lot of funk, plenty of alcohol, and a bit too much carbonation, not exactly a beer I (or many) would drink quickly.


Courage RIS Inspired 2007

Smell – Oaky. Unlike Sir Rupert, it is the wood rather than spirit coming through. Not damp basement, and not Home Depot lumber aisle either. Just a pleasant vanilla-sugar cookie woodiness. A hint of licorice. The roasty-toasty malt is there, but is subtle. Like Sir Rupert the Brett is restrained, honestly makes me more confident that the Brett really did do “something” in the fresher beer.

Appearance – Black with chestnut highlights. Head pours small and drops quickly.

Taste – Every bit as good as it was 10 years ago. Cookie-toasty, vanilla-oaky, cocoa-roasty, and leather-earthy. It is relatively dry for a beer this big, but the bitterness is mostly gone too. I don’t get any wet paper, or any other signs of detrimental oxidation.

Mouthfeel – The body a bit thin, but considering I brewed it when I was 24 and I’m 37 now I can’t complain! A testament to my beginner's luck… and metabisulfite. Carbonation is low, but I wouldn’t mind if it was even lower.

Drinkability & Notes – What can I say about a beer I brewed more than 1/3 of my life ago? The other two are good beers that I enjoy, this one is something special. A huge range of flavors that all work in unison. Sadly this is my last bottle.

On their surfaces the fermentations of beer and wine seem like they should be similar. A cool, sugary liquid is inoculated with Saccharomyces cerevisiae (or a close relative) and the eventual product is packaged with a goal of minimizing oxidation. Why then are the two approached in such fundamentally different ways from yeast pitching rate to the use of oxygen scavengers?

I’ve only made a handful on wine kits over the years so I’m by no means an expert vintner. That said, I’ve been thinking about cider while I wait for TTB-approval to begin production at Sapwood Cellars. The question is, do we approach it like a beer or a wine?

Wine yeast for a Flemish Red

Wine yeast has a different history than beer yeast. Where ale and lager strains have been domesticated for centuries, most wine strains were at best semi-domesticated until the last few decades. A big reason for that is the seasonal production differences between the two products. Dried grain and hops store and ship easily compared to grapes, so harvesting and repitching yeast was common in beer long before wine (which relied on an annual spontaneous fermentation).

Wine strains are still less domesticated (more wild) and thus tend to be more “competitive” than beer yeast, producing kill factors and generally being able to bootstrap up from low cell counts. As a result, suggested pitching rates for wine are usually much lower than for beer. A typical pitching rate for a 1.080 beer might be 3 grams of dried yeast per gallon, where wine is usually 1 g per gallon. This is also reflected in the package size for the strains (5 g vs. 11.5 g).

For home winemakers anyway, it is difficult to find best-practices for things like pitching rate and oxygenation. We can certainly debate the credibility and accuracy of the advice, but homebrewers have widely referenced formulas and targets for these based on original gravity and type of yeast (ale vs. lager).

Riesling Fermentation

Wine must isn't boiled to avoid destroying its fresh fruit flavor, so without chemical intervention there is no “clean slate” to begin fermentation. Even pitching a pure culture of yeast wouldn’t guarantee a product that doesn't eventually sour or go off. That helps to explain the common uses of antimicrobial sulfite and sorbate (which winemakers have widely referenced formulas for dosing rate). Chemical stabilization also allows the packaging of sweet wines, where brewers have mash temperature to control fermentability.

Most of the analysis of wine, must, and fermentation has happened since the 1970s. Where some of the earliest work on microbiology (not to mention scientific measurement) was from breweries a century earlier. Beer became science-ified first thanks to the earlier industrialization of brewing (again a result of the differences in ingredients). 

Saison Fermentation

Modern breweries are built upon keeping oxygen out of the beer post-fermentation. Much of this is accomplished with purging with carbon dioxide or nitrogen and transfers and packaging under pressure. Conversely, conventional wine production relies on dosing with metabisulfite (a potent oxygen scavenger) to neutralize oxidation while the process doesn’t do as much to avoid it.

Part of this is that breweries may make 25 or more batches of beer in a given fermenter each year, while seasonal wineries don’t have this luxury. This means even smaller breweries can afford to spend more on their equipment allowing for transfers under pressure rather than pumps. Dealing with force-carbonation makes pressure vessels a requirement. There are also stages of winemaking, like punch-downs or separating the skins from the fermented wine, that are nearly impossible to do without introducing some oxygen. There is also an expectation of stability and ageability with wine.

Traditionally beer was naturally carbonated, which allows the yeast to scavenge oxygen introduced during packaging. Combine that with typical quick consumption and oxidation wasn't as large of a concern until recently.

Natural wineries that avoid the addition of sulfites do take some cues from brewing in limiting oxygen, but this is currently a growing but still niche winemaking approach.

Chemical additions for a white wine kit

Beer has always been a recipe: grains, water, and herbs at a minimum. Sugars, fruit, spices etc. all have a historic precedent in brewing. It is no big surprise then that brewers are more likely to add 100 different ingredients than vintners who can make wine from crushed grapes alone - although adulteration had a historic place. Most of the wines I see with a "flavor" addition (e.g., chocolate, almond etc.) are inexpensive gimmicks. The lone exception is herbs in wines like vermouth. Where most of the expensive highly sought-after beers contain additions that fall outside of the core ingredients.

Modern wineries add all sorts of processing aids, acid/sugar adjustments, nutrients etc. but generally with the goal of balancing, showcasing, or heightening the fruit expression. Wine strains are now carefully selected to have specific interactions to increase aromatic compounds (e.g., the ability to converts the thiol 3MH to 3MHA). Wine yeast blends are also popular with one strain freeing a compound and another converting it. All things that are rarely considered for brewing.

Brewers have only relatively recently begun to embrace aging in oak barrels, something many wineries never gave up on when stainless steel became the standard. Brewers have very much relied on the secondhand barrels from wine and spirit production rather than buying new or directly supporting coopers.

This goes after the larger point that brewers are currently less tethered to their industry's recent past than wineries. The most popular craft beers of today don't look or smell like any beers that were produced 30 years ago, while wines have remained relatively unchanged. Much of the American craft beer boom was based on taking dead or dying styles, ingredients, and techniques and resurrecting them. It is great to see the same becoming more popular in wine with the resurgence of orange wine, obscure varietals, and natural winemaking.

Barrels for aging

I’m not here to argue that either brewers or vintners are better. I think there are things that each side could learn from the other. Why don’t we see dry hopped wine? Why don’t brewers add 5 PPM of metabisulfite as insurance for the hazy IPAs? Why don’t we see more wineries reduce their sulfite usage by purging their tanks and bottles? Why don’t we see more brewers celebrate the terroir of local ingredients? I even wrote an article for BYO about using wine yeast in beer.

Someone could likely write a similar article about distilleries, cideries, sake-producers, etc. The point is to get out of your box, and see what other experts suggest in their chosen domain. Determine if any of it is useful to what you do!

I've talked to cidermakers who operate just like a winery in terms of their fermentation and highlighting of the apples, while others are clearly more influenced by craft beer (take Graft). We'll likely take a hybrid approach for our ciders, using our best low-oxygen transfers along with winemaking techniques that make sense to us. Celebrating the character of the apples, but still sometimes having fun with additional flavors.

With our first anniversary (and party) coming up, I wanted to write a post on one of the many areas I didn't know anything about as a homebrewer that goes into an event like this. One of my many hats at Sapwood Cellars is compliance. It is a necessary part of the dream job, but luckily not the whole thing! It includes things like record keeping, filing excise taxes, and TTB submissions for formula and label approvals. The taxes took awhile to get used to, but aren't that bad now that we have adequate record keeping procedures in place.

We're lucky to be in that Maryland doesn't require federal COLA label approval for in-state distribution. So we're just now getting into that as we've recently been approved to sell beer in Virginia, DC, California, and Oregon. Don't get your hopes up, for now it's just small shipments for festivals and events (e.g., Modern Times Festival of Dankness, Aslin Anniversary Party, Snallygaster). So far it hasn't been too burdensome, mostly just getting the templates for our labels and keg collars in spec, and then learning what words are required or problematic. It is a bit more work given the wide variety of beers we produce (more than 150 in our first year), but most of those are tasting room only.



The more annoying piece is formula approvals (FONL). Despite what several brewers have told me, formula approvals are required any time you are adding ingredients not in the list of Exempt Ingredients and Processes regardless of whether label approval is required or where/if the beer will be distributed. I called the TTB and had my understanding confirmed. True, the odds of getting in trouble for not having an approved formula are low for a beer that stays in state (especially taproom only), but as a long-time government employee I'm just not an "ask for forgiveness" kind of person. The issue is that it seems approvals are really subjective/inconsistent.

Last fall I'd requested a formula with acorns, to do a small batch with the acorns I dry-fermented. I was rejected. Well that isn't entirely true, what the TTB usual responds is to request the GRAS (Generally Regarded as Safe) notification from the FDA for the ingredient in question. The issue is that they know well that the most ingredients aren't on there, and that the only way to get it there would be to fund a study showing its safety. As a result, most of "GRAS" substances are specific chemical compounds (e.g., Xylooligosaccharides from sugarcane, Ergothionine, and Synthetic dihydrocapsiate) that large companies have gotten through. You know what isn't on there? Apples, while apple peel powder is. Oranges, but orange pomace and enzyme-treated orange pomace is. You get the idea.



When I contacted the FDA about acorns they responded that while acorns were not GRAS, I could use "tannic acid extracted from nutgalls or excrescences that form on the young twigs of Quercus infectoria Oliver and related species of Quercus." Pass...

Recently I saw another brewer mention that they had gotten acorn flour approved (but were still requires submission of a "tannin leaching" process). I submitted a formula for a dark saison with acorn flour, and was rejected again, but this time for the reason that acorn flour is approved without a request being required. Not sure what grinding the acorns up does to change it from requiring FDA study to being allowed without even having to submit a formula request.

Something similar happened with Staghorn Sumac (which I'd used at home with wonderful results). GRAS notification was requested from my submission, which annoyed me because I've had several commercial beers brewed with. I responded:

Maybe I am misunderstanding the GRAS Notices? It doesn't seem to include most of the typical ingredients added to beer, e.g., hops or barley. Most of the entries are for chemical compounds or specific extractions from plants, not fruits, vegetables, or other commonly consumed foodstuffs? Rhus typhina (staghorn sumac) has been made into a lemonade-like drink for centuries. Here is an info sheet from North Dakota State on the species, that includes: "Food - Sumac lemonade made from berries."

Three weeks later and my formula was approved without further comment...

I've got nothing against safety rules on what goes into beer. I'd just prefer they were clearly delineated and widely followed.

Since both of these ingredients are foraged and thlimited, we decided to make 15 gallon variants with each for the anniversary party. A barrel-aged dark saison (based on Funky Dark #4) for the acorns and a pale sour fermented with The Yeast Bay Melange for the Sumac!
