Ales vs. Lagers

Top Fermenting Yeast-Saccharomyces cerevisiae

Have you ever wondered what exactly is the difference between an Ale and a Lager? Let’s chat about it.

There are two different categories of beer- “Ales” and “Lagers.” Within these two categories are hundreds of different styles that can vary widely in taste, bitterness, color etc. Ales are brewed with a top-fermenting yeast, while Lagers are brewed with a bottom-fermenting yeast. What does this mean to you? Hold on for a minute while we geek out just a bit.

Top-Fermenting yeast or Saccharomyces cerevisiae as we like to call it, is the most common yeast out there. Chances are, you consume it on a daily basis. This is the type of yeast that is common in bread making, wine making and beer making. Pretty good stuff, right? The reason we say it is top-fermenting is because as the fermentation process happens, the yeast cells circulate throughout the beer, magically converting the wort (sugary water) into alcohol and C02. As the process finishes, the yeast rises to the top creating a thick Krausen and if not removed, will drop to the bottom of the fermentation vessel. Ale yeast ferments at a warmer temperature (between 60F-75F), and because of this, reaches attenuation at a faster pace than Lagers.

Saccharomyces uvarum (Bottom-Fermenting) yeast cells work from the bottom up, at a slower pace and a colder temperature (46F-59F). The term “lager” comes from the German word “lagern” which means “to store.” The discovery of lager yeast is believed to have been made in the Middle-Ages when Bavarian brewers fermented and stored their beers in ice caves over the winter. Because of the longer, colder fermentation process, Lagers are generally very crisp and clean tasting.

Did any of that make sense? We hope so, but let’s be honest, at the end of the day- Ales or Lagers, we love them all!

Happy November! Pints for a Purpose 2015/2016

Fall is here and we are very excited to announce the 2015/2016 recipients for our Pints for a Purpose program. For those unfamiliar with Pints for a Purpose, let us explain. Each year, we invite local nonprofits to submit applications on behalf of their organizations and we as a staff vote to choose our top five favorites. November through March each group is awarded their own special evening, and from 5-10 p.m. $2 of every pint of beer sold goes straight to their organizations. We invite the group’s representatives to spend the evening with us, and share a pint as they answer questions, and offer information as to who they are and what they do. Here is the lineup for this year:

March 9- No LNG Campaign 

No LNG Exports Oregon is a statewide coalition of activists, experts, and community members with the goal of stopping two LNG pipeline projects in Oregon.

So there you have it! Last year, we raised over $2,300 (that’s 1,150 pints!) benefitting five different wonderful nonprofits including, Rogue Climate, Water Watch of Oregon, Friends of the Ashland Public Library, Rogue Farm Corps and Rogue Valley Earth Day. We are very happy to continue with the tradition and hope you join us at one (or all) of our Pints for a Purpose evenings this season.
