Ask the Brewmaster: My Homebrew Smells Like Rotten Eggs and Corn!

This Month’s Question:  My beer sometimes has a corn-like sulfury smell.    What can I do about it?

Answer:  A corn-like smell is usually due to a specific chemical compound called dimethylsulfide, or DMS for short.  DMS forms in the malting process and in the boiling process while brewing any beer.  It is the result of a thermal degradation of sulfur-containing amino acid in the grain called s-methylmethionine.   This amino acid is present in all malts.  Hence, all beers have some amount of DMS.

DMS is a highly volatile compound.  This makes it an easily detectable compound in aroma, even in trace quantities.  Fortunately, the volatility makes it fairly easy to scrub out of your beer.

DMS-scrubbing-by-co2

The amount of DMS in your finished beer depends on a number of factors.  First of all is the amount of s-methylmethionine in the grain.  High protein malts such as six-row have higher amounts, hence more DMS.  Some of the DMS is driven off by heat in the kilning process.  Hence, the paler malts kilned at lower temperature have more.  These two factors combined contribute to the fact that pale lagers (made from pale six-row malt), often have high levels of DMS.  Not surprisingly, corn also contains a lot of s-methylmethionine.  These characteristics are a hallmark of lager beers.  A lager without DMS tastes rather bland.

The second factor that affects the amount of DMS is how much is removed from the wort during the boil.  Every bubble of steam that comes out of the kettle will carry some DMS with it.  Hence, longer boiling times and a more vigorous boil tend to reduce DMS levels.  For best results, you want to keep the boil rolling for the whole time.  Don’t simmer your beer!

New Club Website

The new club website also marks the demise of our monthly newsletter and periodic email announcements.  In the interest of reducing overhead and duplication of effort, the website will become the club’s primary method of communications and will essentially replace the newsletter and emails.  The monthly newsletter will evolve into a monthly flyer promoting that months events with the rest of its monthly content  moving to the website.  The email announcements will be replaced with notifications from the website when articles are posted.

Pacific Gravity’s Summer ‘Party Gras’: Who Needs a Bayou When You Got Beer?

IMG_1445Ooh-wee, baby, ooh-wee. The good times rolled and the great beer flowed at Pacific Gravity’s 13th annual Summer Party on July 18, which brought a bit of New Orleans revelry to the Pacific Palisades plantation estate of club member Dean Sussman (right), the site of the celebration for seven years running.

Bedecked in strands of Mardi Gras beads, over 275 club members, guests, families and friends got their Creole on for this homebrew fais do-do, grooving to iPod mixes of N’awlins funk, Cajun zydeco, swamp rock and Dixieland jazz, noshing on Louisiana-styled eats, and swilling down a wide variety beer –– both homemade and commercial –– and sodas. And the perennial “Home Brew Club Summer Party Band” reformed once again to contribute a couple sets of booty-shakin’ blues rock. Think Fat Tuesday during Mardi Gras –– except nobody had to give anything up the next day!

Special guests at the party, all of whom were among the many who donated gifts for the party raffle, included Larry James of Wine Warehouse distributors (who brought along a four-year-old keg of Echte Kriek!), former club member Michael Bowe of Angel City (who tapped kegs of his Vitzen and IPL – India Pale Lager), Paige Reilly of Shmaltz Brewing, Brian Lenzo of Blue Palms Brew House, Ryan Sweeney and Brandon Bradford of Verdugo Bar and BoHo, and Billie Anderson of Lucky Devils. Also, beer-blogger Sean Inman was in the house, and covered the party for the Food GPS blog.

Club master chef Ian Fraser came out of semi-retirement to oversee and help prepare the massive New Orleans-influenced feast, Read more

Mead Day

Meadday-header

Did you know that Saturday August 1 is the American Homebrewer’s Association National Mead Day?  It is, and Pacific Gravity will be having a Mead Day Celebration at the home of Dan Hakes (that’s me!).  We will be brewing, tasting and talking about mead.  Last year Mead Day was held at my house and we put some black walnut and fresh apricot in two separate batches of two-year-old mead.  We will be sampling these on Saturday.  We can also sample the mead we made last year and see how it’s coming along.  I have a few others sitting around and you never know what I might find in the cellar.  If you have some mead to share, bring it along.

Michael Steinberg will be bringing snacks, and the Carriage House Taproom will be open.  Drop by, socialize, and watch how easy it is to make mead!

Also on mead day, we will be selecting the Club’s next entry for the AHA Club-only competition.   The next competition is for Amber Hybrid beers, BJCP category 7.  We will judge them at Dan Hakes’ place.   Please bring 3 bottles for each entry, and please fill out the entry forms which you can download from the AHA website at:http://www.beertown.org/homebrewing/pdf/entry_recipe.pdf.  The club picks up the entry fees and shipping for this one, so it is free to you.

Road Trip to Stone 13th Anniversary Fest

Stone 13th AnniversaryThis year’s event will take place Saturday, August 22, on the campus of Cal State University San Marcos in North County San Diego. And for the fourth time, Pacific Gravity will be chartering a beer bus to shuttle thirsty club members from Culver City to the first session (only) of the fest, which lasts from 11:00 a.m. – 2:00 p.m.

How do you get on board? It’s easy.

BUY YOUR FESTIVAL TICKET

First, buy your own ticket to the Stone Fest’s morning Session A (only; the PG bus will NOT be traveling to the afternoon Session B). Tickets are $35 per person and are available now.

Order your tickets ASAP. Not only does the first session always sell out, but on August 15, the ticket price rises to $40. The price buys you entrance to the event, a 13th anniversary tasting glass and 10 taster pours from over three dozen breweries. And don’t forget to bring your ID. Yes, they check.

ONCE YOU HAVE YOUR STONE TICKET, BUY YOUR BUS TICKET

Then, reserve a space on the PG bus, by paying $30 per person ($31 if using PayPal). You can use the “PAY NOW” button below or drop your payment off at Culver City Homebrew Supply, or sign up for the road trip and pay at the Summer Party on July 18. Don’t delay in reserving a space on the bus either; it has sold out in previous years. Rest assured, beer drinking IS allowed on the bus –– and there will be a working bathroom on board as well!

The bus will leave from Culver City Homebrew Supply at 8:00 a.m. sharp on Saturday, August 22. Do not be late or you will be outta luck. A lunch stop (probably at one of the Pizza Port brewpubs) will be made en route home, and we should arrive back at the homebrew shop by 6:00 p.m.

By the way, Stone’s 13th Anniversary Ale, due to hit store June 29,
is an Imperial Red hop monster at 9.5% abv.

Don’t miss out on the club’s most popular road trip of the year!
