This blog is about beer and life.
Beer is Green
Beer is greener than you might have known. E-Fuel, the maker of the EFuel100 MicroFueler ethanol maker has teamed up with Sierra Nevada to use the left over yeast from the brewing process, called trub, pronounced “trube”, to test the invention. I love it, yet another reason to pour another pint. 
E-Fuel last year unveiled its $9,995 home ethanol machine which ferments a mix of water and sugar into ethanol. Ethanol is mixed into gasoline at 10 percent. Flex-fuel cars can run on E85, an 85 percent blend of ethanol and gasoline.
Sierra Nevada every year generates 1.6 million gallons of “bottom of the barrel” beer yeast waste, which it now sells to farmers as feed. The MicroFueler will be able to raise the alcohol content in that mix to 15 percent and remove water.

Glissade Golden Bock

After last year, I’ve been rather reticent to write up a beer tasting. But, well, the weather is getting rather “Spring-y” out there and, well, I’ve never seen this at my retailer. It’s a great time for a bock. They say: As winter begins its slide toward the sunny days of spring, we bring you

When “ale” did not mean “beer”
about 8 months ago - No comments
“Ale” and “beer” have not always been synonymous. Used to be ale didn’t have hops, for one thing. Zythophile (a favorite read of mine) offers up a lengthy article on when the two terms merged. It’s not as simple as many think. Why weren’t stout and porter called ales? This is a reflection, 200 years

Beer-a-Day #291 Kellerweis is one of the only American Hefeweizens made using the traditional Bavarian style of open fermentation. This difficult and labor-intensive technique adds uncommon depth and flavor complexity. Our hazy-golden hefeweizen is deeply flavorful, refreshing and perfect for a sunny day. To serve, pour two-thirds into a glass, swirl and pour the rest.
Sierra Nevada Torpedo Extra IPA

Beer-a-Day #289 Sierra Nevada Torpedo Ale is a big American IPA; bold, assertive and full of flavor and aromas highlighting the complex citrus, pine and herbal character of whole-cone American hops. I’d been hearing a lot about this beer, but I wasn’t seeing it at any of my local retailers. I’m glad it came into

40 Random Beers Ratings

Of the 40 beers I received for my birthday I’ve tracked thus far how each has rated against the unofficial Hop-Talk beer rating scale. I am a bit behind on my posts, so the snapshot below is probably from mid-February. The highest score is a 5, which we have never officially given to a beer,
Session #23: What I will NOT miss from 2008
about 1 year ago - 2 comments
I don’t want to put a downer on it all, but 2008 was not one of the best years I’ve had. I could swing this as a “looking forward to 2009″, but let’s face it… this is just a “buh-bye” to 2008. For this Session, I’ve put together a top 5 things I will not
