Brewing Process

beer process illustration


Malting is the process in which raw barley or another grain is made ready to become the main ingredient in the brewing process. The grain is steeped in water, then rested under precise conditions to encourage germination, and finally dried in a kiln and/or a roaster.

Milling takes the whole barley or wheat kernels and cracks them open, being careful to not crush the barley to dust. The husks end up being a very important part of the brewing process down the line.

This is the process of mixing the crushed malt with hot water at a very specific temperature. Given the right conditions, enzymes in the malt activate and go to work converting starches into sugars. This process takes between 30-90 minutes.

(German for “recirculation”)

The process of clarifying the liquid (now called wort - pronounced wert) by recirculating from the bottom of the mash back on top of itself. The mash/grain bed, including the intact husks from the milling process, becomes a natural filter bed thus clearing the wort over about 15 minutes.

The process of separating the wort from the spent grain while extracting as much of the sugar still trapped in the grain. This clear wort is slowly transferred into the boil kettle. The leftover spent grain is given to a local farmer to use as livestock feed.

This is where the wort is boiled, concentrated, and volatile compounds are boiled off. Hops are added for bitterness, flavor, & aroma throughout the boil; sometimes other flavors are added here. Typically wort is boiled for 60-90 minutes.

Once the wort is boiled, it gets transferred to the fermenter. As the wort is transferred, it passes through a heat exchanger, cooling it to a specific temperature. Once the transfer is complete, yeast is pitched into the fermenter. Over the next 4-6 days the yeast consumes all of the sugars, turning them into alcohol and carbon dioxide. When fermentation is complete, the liquid is now officially beer. The beer is cooled to 30 degrees for conditioning, this process helps clarify the beer & allows us to collect the yeast for reuse.

Final Transfer

Once the beer has conditioned, it is time for its final transfer into a serving tank. This is where the beer is carbonated to the appropriate level, and served in a beautiful, “beer clean” glass.

Meet Our Brewers

Jon Lambert

I am Jon Lambert, Head Brewer, and partner at HCB. I started home brewing in 2010 before taking it up a notch (or ten) and turning pro. I love the brewing process but, more than that, I love sharing beer with friends and family. Brewing is an extension of cooking for me, using high quality ingredients, solid processes, and attention to detail. While brewing I create a specific goal and, although I may not hit the bullseye every time, I believe this mindset has made me better at my craft. When I am not brewing, I love to cook, camp, mountain bike, and explore the great outdoors.

Rachel Leiby

Hey all, I am Rach! I have been brewing for two and a half years. Something uncommon about my brewing career – My very first batch of beer was done leading a team of women of varying skill levels for the Pink Boots Society’s International Women’s Day collaboration. I have since led another Pink Boots Brew Days and look forward to many more! Pink Boots Society helps women of all skill levels learn and succeed in the fermented/alcoholic beverage industry.

I have worked at three breweries, starting as an assistant brewer before becoming a head brewer and am now a brewer at Hairy Cow Brewing Company. I have learned a great deal in each position and am excited to be part of the Hairy Cow team!
