The ABC of Beer available at Castle Rock Homebrew Supply

 Any beer needs three basic things: grain, hops and yeast

(water is also super important of course)

At Castle Rock Homebrew Supply we provide a wide selection of the previous three so home brewers can working on their unique creations.



Brewers soak malted Barley, Wheat and Rye in hot water to convert starches to sugars for yeast to ferment into alcohol. Some grains provide a base flavor and some grains are used in small quantites to provide unique flavors, aromas and mouth feel. We have one of the largest selections of malts and adjuncts in the homebrew industry with over 80 well organized grains. Our grains originate from 3 continents and over 10 maltsters. Still, if you don’t see it, we can get it. 


HopsBeer hop trees

Hops add bitterness to beers to counter the malt sweetness. Hops also add flavor and aroma when added late in the brewing process. We carry one of the largest selection of 1 oz pellet hops with over 70 varieties. We also carry the most popular in 1 lb bags. Nitrogen packaged leaf hops are also always available. 





Yeast are single cell organisms that complete the process of fermentation. Yeast consumes various types of sugars and produce Ethanol, Carbon Dioxide and flavor and aroma compounds. Yeast makes the beer! Many homebrewers also use yeast in the bottle to carbonate their beer. This process is called bottle conditioning. We carry WYEAST, White Labs and the local liquid yeast company, Inland Island. For dry brewer’s yeast, we have a huge selection from Lallemande, Fermentis, and Mangrove Jack. We also carry a large selection of dry wine yeast and distillers yeast.

We have flasks, stir plates, yeast nutrient, slant tubes, and aeration systems to grow and propagate your yeast.
