The grid like pattern on the Stochasticity Project Grapefruit Slam IPA bottle label is a two-dimensional random walk. Random walks explain observed random behaviors and processes and are the most elementary way of showing recorded stochastic activity. Random walks allow us to find patterns in behaviors and processes that seem random. In short, randomness isn't really that random after all.
Titrations need four things: sample, acid, base, and an indicator. You add acid to a base and indicator-infused sample and by knowing the exact volume of acid added to neutralize the basic solution and change from pink to blue, you can determine how much of a substance is in solution. Titrations are used to determine the total amount of hardness, calcium, and alkalinity in brewing water. This is…
Triangle testing is an essential part of our sensory program. It involves a set of three samples - one sample is a test and the other two are experimental controls which are presented blind to the taster. The goal for the taster is to try to determine which sample tastes different from the other two. This test is an important, unbiased way of determining if a change in the brewing process…
UV-vis spectrophotometers are the swiss army knives of brewing chemistry because of the sheer amount of compounds it can analyze for and for the cheaper price tag.
Spectrophotometers (“specs” for short) are used to measure the amount of iso-alpha acids in beer, which gives you IBUs.
Specs can also measure, in wort and beer, the amount of free amino…
The vanilla compounds from the spirit barrel combine with the fruity esters from the Belgian yeast, and in the case of this particular beer, some tropical fruit and citrus notes from the hops that we chose for the whirlpool addition. The furan compounds in the bourbon barrel will give some light caramel and toffee notes to the beer, and a slight perceived sweetness. All this combines…
Just like the universe, we're expanding. All the time. You may recall from our big announcements back in May 2011 that we were embarking on a $50M+ expansion plan to include several new adventures including: Stone…
Craft beer is life here at Stone. In the best cases, however, our beer has the ability to make positive impacts on the lives of others. Such is the case with one of the first beers brewed up on our brand new ten-barrel brewhouse at our equally new second farm-to-table restaurant,…
They say good things come to those who wait. Fermentation has proven this true for us time and time again; however, we are, at our core, pretty darn impatient. We have grand aspirations and want to push the craft beer envelope by providing new ways for people to experience hand-crafted ales and lagers. Grand aspirations require grand gestures. Grand gestures take grand effort. Grand effort…
As the Brewing Manager at Stone Brewing World Bistro & Gardens – Liberty Station. I would like to introduce a new series of beers that will rotate through our central San Diego brewery-restaurant. We at Stone make no secret of our love for hops and are always pushing the boundaries with beer experimentations—especially when it…
On October 9, 2014, we announced the selection of Richmond, Virginia, as the home for our upcoming Eastern U.S. brewery, packaging hall and Stone Brewing World Bistro & Gardens farm-to-table restaurant. Located in the city’s Greater Fulton community, the project site offers everything we asked for and more, even though, at first glance, few might be able to see its potential…
