The Big Green Blog Post


When I was a kid, my mom had an old green Volkswagen bus, you know, similar to the one in Scooby-Doo; the iconic hippie-mobile. At the time I was really embarrassed by my mother’s eccentric taste in automobiles, but looking back it made perfect sense. The beads in her hair, the penchant for woodworking, and the green VW bus all pointed to one thing—she was a TOTAL hippie. Naturally, hippies were the first thing that came to my mind when I saw The Big Green Bus pull into our parking lot here at Stone on Wednesday afternoon, leaving a pungent aroma of hash browns in its wake.

The Big Green Bus

The Big Green Bus is a full-size bus (1989 MCI Motorcoach, to be exact) remodeled by 15 Dartmouth students to be as sustainable and energy efficient as possible. The students are taking their green labor of love on a summer-long cross-country tour to raise awareness about sustainability and energy-efficient practices. And it smells like hash browns because it runs on 100% recycled vegetable oil, not because the students have a deep affinity for breakfast fare.

At first glance, The Big Green Bus looks like a glorified version of my mom’s old green VW bus, but that couldn’t be father from the truth. “We spend a lot of time convincing people that we’re not gross-smelling hippies,” said one student, “most of us showered this morning.” The Big Green Bus is much more than a meagerly-funded flower-child mobile with wicked green graphics. Along with running on biodiesel, the bus is also a mobile showcase of environmental conservation. Everything inside, from the low-energy plasma TV to the recycled bamboo flooring, is the epitome of energy efficiency.

If a summer-long tour on The Big Green Bus sounds like a great time, think again. These kids work hard. According to Kerry, it’s about 90% work and 10% play. Not exactly your quintessential summer of love. Everywhere the students go they’re greeted by news cameras and general media hubbub, and Stone was no exception. Escondido Mayor Lori Pfeiler, the folks at the California Center for Sustainable Energy, and a bevy of local media joined us in welcoming them to Stone on Wednesday afternoon.

So why did they come to Stone? Because they were hungry, of course (I guess word got out that our Bistro serves locally-grown, organic food). They also enjoyed a tour of the brewery and learned a bit about our solar array and our other efforts to operate sustainably. But most importantly, they came to fill up their tank with our Bistro’s used vegetable oil—the same stuff that our Lead Brewer John Egan uses to power his truck.

We’re stoked The Big Green Bus chose to stop and share a part of their journey with us, and we’re glad we could help spread their message. If you spy a lumbering green bus speeding down the highway smelling like Sunday brunch at iHop, give those hard-working Dartmouth students a honk in support. They deserve it.

HOPPY 13th Anniversary To Us…


With all the latest beer gossip just a click away, it’s near impossible to keep a secret these days. Many of you may have heard rumors about Stone 13th Anniversary Ale, but it’s time we set the record straight. Here’s the official word:

Take your idea of a hoppy Stone beer and throw it out the window, because Stone 13th Anniversary Ale is the hoppiest beer we’ve ever brewed. Just how much hops is in this year’s batch? You may want to sit down for this…4.5 lbs. PER BARREL! To lend you a bit of perspective, Stone 10th Anniversary IPA, revered by many as the quintessential hopped-up Stone Anniversary Ale, had about 2.5 lbs. per barrel.

Stone 13th Anniversary Ale has officially trumped our collaboration brew, BrewDog / Cambridge / Stone Juxtaposition Black Pilsner, as our hoppiest beer. Of course, all those hops would be worthless if the beer wasn’t balanced. That’s where brewers Mitch Steele, Tom Garcia, and John Egan came in.

When Steve and Greg gave the green light, Mitch, Tom, and John took the reins of the recipe. The beer went through three iterations before they dialed it in, finally deciding on Chinook hops for bittering and a 50/50 blend of Centennial and Simcoe hops for dry hopping. The careful blend of hops, combined with pale malt, various crystal malts, amber malts, and just a touch of chocolate malt, resulted in a rather tasty 7% abv red ale—but it just wasn’t quite worthy of a Stone Anniversary Ale yet. “It had a nice hop character,” said Mitch, “but it didn’t have that extra something that I thought the beer needed.” After tasting it, Greg even asked Mitch “It’s going to be bigger, right?” To which Mitch replied “Yeah, it’s going to be bigger.” The solution was to bump up the hopping and alcohol a bit, and the result was a very big, very Stone 9.5% abv Ale. As if that wasn’t enough, the brew crew decided to dry-hop it again just prior to filtering and packaging.

When asked to describe Stone 13th Anniversary Ale in one word, guess which word Mitch chose? You guessed it–“Hoppy.” Sure, it’s a monstrously hopped, extremely bitter beer, but it also has a bold malty character that balances out the bitterness. “It’s really bitter, but it’s also malty,” said Mitch. “It’s pretty well balanced; not as dry as you’d think.” Dr. Bill agreed with Mitch when he tasted it. “It’s really well balanced for as hoppy as it is,” said Dr. Bill. “And it has a nice malt complexity with hops throughout.”

Mitch knows that hop-heads who missed hops in last year’s Stone Anniversary Ale will rejoice, not only because Stone 13th Anniversary Ale is a hop monster, but because it’s damn good. “I think it’s going to be right up there with some of the older Anniversary IPA’s,” he said, “and if all goes well, right up there with the Tenth.” We’ll let you decide when Stone 13th Anniversary Ale is released on June 29th.

What the Hell is Stone Bombastic Lager?


That’s the exact same question I asked our Lead Brewer (and infamous biofueler) John Egan after seeing the pompously named beer rear its head in various places, such as on the tap list for Southern California Storm and on the Stone Company Store’s growler fill schedule. So what’s the official word?

To sum it up, Stone Bombastic Lager is the beer left over from propagating the pilsner yeast we used in BrewDog / Cambridge / Stone Juxtaposition Black Pilsner. What does that mean? Let me explain.

When we acquire new yeast to propogate (pilsner yeast in this case), we throw it in our yeast propagating tank, and over the course of a few days we continually add wort to “feed” it and facilitate yeast growth. To feed the pilsner yeast, we added Stone Pale Ale, Stone IPA, and Stone Imperial Russian Stout wort straight from the brewhouse into the yeast propogating tank over several days. Once we were confident that there was enough growth, we pumped the yeast off the bottom (lager yeast is bottom-fermenting) and sent it over to the fermenting tank to ferment the Collaboration brew. John then transferred the leftover beer into another tank, but before transferring it he had a spark of creativity and decided to add some crushed coriander, french oak chips, and “literally a handful” of chopped vanilla beans. It sat for about a week or so, and then we gassed it up and put it in kegs. There were no additional hops or malt added; it was just a blend of a few worts.

“As far as style goes, I have no idea,” said John. “It’s kind of a ‘suicide’ like we did as kids with our sodas; just a mix of whatever is available. It tastes like an ale to me, but it’s a lager—and a weird lager at that!” John added that the brew weighs in at 6.8% abv.

So there you have it. Now when you stumble across Stone Bombastic Lager on the tap list at Southern California Storm or on tap for growler fills in the Stone Company Store on May 15th and July 10th, you can wow your dumbfounded friends with your in-depth knowledge, complete with a healthy dose of bombast.

John Egan Brews His Own Fuel Too


Remember last summer when gas prices were ridiculously inflated? Remember wiping away the tears while your hard-earned cash ticked away at the pump faster than our national debt? John Egan doesn’t. While the rest of us were subject to the tyranny of fossil fuels, John avoided gas stations entirely, comfortably enjoying his wallet-friendly biofuel solution. When John isn’t supervising our brewing team, managing our cask and barrel aging program, and watching over our prized special creation beers (like Stone Smoked Porter with Vanilla Beans), he’s indulging in his green side by converting 100% of our Bistro’s waste oil into biodiesel fuel to power his truck. So how does he do it?

John Egan’s 1999 Dodge Ram 2500, which weighs 7,000 lbs., can get up to 24 mpg using biodiesel. John also uses biodiesel in his 1980 Mercedes Benz 300D.

Every other week, John uses an electric pump powered by his truck battery to extract waste oil from a 50-gallon drum behind our Bistro. Once the oil is filled back into the containers it first came in, he takes it home, processes it in the custom-built system in his garage, dumps it in the tank of his truck, and voila!

So what does biodiesel have to do with beer? Well, according to John, being a brewer comes in handy. “There are a tremendous amount of parallels between biodiesel and brewing,” said John. “You take raw materials and turn them into something else, and quality is extremely important. Much of the same equipment is used such as pumps, hoses, valves, tanks, filters, etc.  Actually, used brewing equipment would work exceptionally well to make biodiesel with.”

While John genuinely enjoys “taking waste materials and turning them into something of value,” he admits that brewing biodiesel isn’t a walk in the park. “It’s quite involved and takes effort,” said John. “It’s not one of those things that you try out, and then decide to scrap after a few months.”

Sure, brewing biodiesel isn’t easy, but it is easy on the wallet. After processing, one gallon of biofuel comes out to about $1. Aside from being outrageously cheap, biodiesel also runs a lot cleaner than regular diesel, and emits a pleasing french fry smell as an added bonus. It can be slightly less efficient than regular diesel, though still more efficient than regular gasoline.

John is obviously a fan of the environment, but he’s also realistic. He feels that biofuels are “an important part of our energy matrix as a supplement, but they aren’t the solution to our energy problems.” Sure, biofuel may not be the magical panacea for our energy woes, but it definitely helps. John put it best when he said “it feels very good to reuse things that would otherwise find their way into a landfill.” That’s something I think we can all agree on.
