So a buddy and I were having a conversation about final gravity. I have several recipes that have finished below 1.010. Around 1.005-1.008 to be exact. He mentioned getting that low usually means wild yeast was introduced somewhere. I've only been brewing for a year and typically US-05 is my go-to yeast. What do you think of this hypothesis?
I think it's completely off the mark unless the beers taste like they're infected.
Yes, you should, but it's not completely necessary if you're trying to keep your first brew day simple. With an extract kit, as long as your volume measurements are accurate, your OG will be on target since all you're doing is dissolving a known quantity of sugars in a know quantity of water.
Similar to the arsenic in apple juice craziness that hit the media a while back, beer is now getting its arsenic inspection.
Mehmet Coelhan, a researcher at the Technical University of Munich, reported that nearly 360 beers tested in Germany had some trace amounts of arsenic. And while
arsenic is a natural substance that seems to pop up in water and apple juice, a few of those beers were found to have more than 25 parts per billion of arsenic. The standard for drinking water in the States? Ten parts per billion.
NPR reports that the source of arsenic seems to be the filtering process, which uses diatomaceous earth that contains iron and other metals. "The levels shouldn't be alarming, because it's the kind of thing you see in dust or air," Roger Boulton, a professor at University of California, Davis, told NPR.
The same filtration process, NPR notes, is also used for wine, and while there seems to be no taste appeal for filtering wine or beer, there is definite visual appeal in a clear, cold brew, or a crisp glass of white wine.
There aren't many other options for filtration, NPR notes, as other methods affect the taste of the brews and wines more so than diatomaceous earth. And while this means maybe we should all try some cloudy brews, let's note that the same arsenic scare occured with apple juice, to no avail. While studies found 10 percent of apple juice to contain more arsenic than drinking water standards, the FDA claimed that "a risk to public health does not exist for apple juice. Unlike drinking water, the levels routinely found in apple juice are either not detectable or occur at very low levels."
Sam Calagione started on a 10-gallon system. Just sayin ;-) obviously not ideal
He's also incredibly good at marketing and self-promotion. Yeah, life is easier if you have a lot of talent. If you don't, you'll need help.
