For those of you who have never heard of SMaSH beer recipes, SMaSH is an acronym used in homebrewing for single malt and single hops. A SMaSH beer is a beer brewed using only one variety of malt and one variety of hop. This is significant since most beer recipes involve several different malts and several different hops. But SMaSH beer recipes only involves one malt and one hop.
After perusing Dave Miller’s Homebrewing Guide for some new beer recipes, it occurred to me that a very short list of ingredients could be used to brew a range of very different brews. With a single type of malt extract, a single hop, and a single yeast strain, you could brew a bitter, an ESB, and an IPA, simply by changing the proportion of ingredients used. This offers an opportunity for brewers to take advantage of bulk pricing on homebrew ingredients (which we offer here at E. C. Kraus), while still being able to brew a variety of beer styles.
The three SMaSH beer recipes below (all single malt, single hop, five-gallon batches) will require a total of:
- 16.5 lbs. light dried malt extract (DME)
- 9 oz. Kent Goldings hops
- 3 packets Safale S-04 ale yeast
Feel free to amend the beer recipes with other ingredients you may have on hand, such as different hops or some specialty grains. Alternatively, treat these brews as an experiment to get a strong sense of what each ingredient can contribute to a beer. All 3 SMaSH beer recipes assume brewing with a five-gallon kettle. Follow the instructions for extract brewing to brew each recipe. Don’t forget your caps and priming sugar!
