TL;DR: A SMaSH beer is brewed using one type of malt and one hop variety, making it easier to taste exactly what each ingredient contributes. SMaSH brewing is especially useful for learning how different malts and hops affect flavor, aroma, bitterness, color, and body without other ingredients getting in the way. Watch Craft a Brew's guide to brewing a SMaSH beer to see how simplifying a recipe can help you better understand malt and hops.
Beer recipes can become complicated quickly. Some contain several different malts, multiple hop varieties, specialty ingredients, and carefully selected yeast strains.
That's the idea behind a SMaSH beer recipe, which stands for Single Malt and Single Hop. Instead of building a complex grain bill and hop schedule from numerous varieties, you choose one malt and one hop and let those ingredients take center stage. For homebrewers, it's both a brewing method and a useful experiment.
What Does SMaSH Mean in Brewing?
SMaSH stands for Single Malt and Single Hop.
A single malt single hop beer — or SMaSH — uses exactly one malt variety and one hop variety. A traditional SMaSH recipe contains: one malt variety, one hop variety, water, and yeast. The goal is simplicity. Using fewer variables makes it easier to identify what a particular malt tastes like and what characteristics a particular hop contributes.
That's especially helpful when you're learning ingredients or experimenting with a hop you've never used before.
Why Brew a SMaSH Beer?
SMaSH brewing helps remove some of the complexity from recipe formulation.
When a beer contains several malts and hops, identifying which ingredient produced a particular flavor can be difficult.
A SMaSH recipe gives you a clearer picture.
Learn What Malt Actually Tastes Like
Malt provides fermentable sugars, but it also influences:
- Flavor
- Color
- Aroma
- Body
- Mouthfeel
Using a single malt makes its characteristics easier to recognize.
Learn What Individual Hops Taste Like
Different hop varieties can produce dramatically different aromas and flavors.
Depending on the hop, you may notice:
- Citrus
- Pine
- Floral notes
- Tropical fruit
- Stone fruit
- Herbal character
- Spice
- Resin
Using only one hop lets you experience that variety without another hop competing with it.
Craft a Brew uses a similar approach with its Single Hop IPA, where a clean malt foundation allows one hop variety to showcase its individual aroma, flavor, and bitterness.
Improve Your Recipe-Building Skills
One of the best reasons to brew a SMaSH beer is to learn beer ingredients individually before combining them. Once you understand ingredients on their own, combining them becomes easier. Instead of choosing malt and hops because a recipe tells you to, you begin understanding why those ingredients work together.
That's what makes SMaSH brewing particularly useful for homebrewers interested in eventually developing their own recipes.
What Malt Should You Use for a SMaSH Beer?
Choose a malt capable of forming the foundation of the beer.
For all-grain SMaSH brewing, common choices include base malts such as:
- 2-Row
- Pilsner malt
- Pale ale malt
- Vienna malt
- Maris Otter
Each provides fermentable sugars while contributing a different malt character.
For example, a relatively neutral base malt can make it easier to focus on your chosen hop, while a more flavorful malt can turn the experiment into an opportunity to explore both ingredients equally.
If you're new to brewing, Craft a Brew's How to Make Beer guide explains the role malt plays alongside hops, yeast, and water.
What Hops Should You Use in a SMaSH Beer?
Almost any brewing hop can become the focus of a SMaSH recipe.
The best choice depends on what you want to learn.
Popular hop profiles include:
| Hop Character | Flavors You Might Explore |
|---|---|
| Citrus | Grapefruit, orange, lemon |
| Tropical | Mango, passion fruit, pineapple |
| Piney | Pine, resin |
| Floral | Flowers, perfume |
| Herbal | Grass, herbs, tea |
| Spicy | Pepper, spice |
| Stone fruit | Peach, apricot |
A versatile dual-purpose hop can be especially useful because the same variety can contribute bitterness during the boil and flavor or aroma through later additions.
Craft a Brew's Single Hop IPA approach uses one hop variety across bittering, flavor, and aroma additions, making it easier to understand the full range that hop can contribute.
How Can One Hop Create Different Flavors?
Using one hop doesn't mean adding it only once.
Timing changes what you get from the hop.
The same hop variety can be added at several stages during brewing.
Early Boil Additions
Hops added earlier in the boil generally contribute more bitterness.
Later Boil Additions
Adding hops closer to the end of the boil preserves more of their flavor and aroma.
Dry Hopping
Hops added after the boil during or after fermentation can emphasize fresh aromatic hop character without contributing the same level of bitterness as a long boil addition.
This means a SMaSH recipe can still have layers of hop character even though every addition comes from the same variety.
Is a Single Hop Beer the Same as a SMaSH Beer?
Not necessarily.
A single hop beer uses only one hop variety but may contain multiple types of malt.
A true SMaSH beer simplifies both sides of the recipe:
Single Malt + Single Hop
This distinction matters.
A single hop IPA can be a great way to explore hops, even if its malt bill contains more than one grain.
Craft a Brew's current Single Hop IPA, for example, is specifically designed to highlight one hop variety against a restrained malt profile.
How Do You Brew a SMaSH Beer?
Knowing how to brew SMaSH beer doesn't require a completely different process from any other beer — the overall steps are the same. The simplicity comes from the ingredient selection, not from skipping important brewing steps. For an all-grain SMaSH recipe:
- Choose your malt.
- Choose your hop.
- Mash the grain to convert starches into fermentable sugars.
- Separate the wort from the grain.
- Boil the wort.
- Add your single hop at the desired times.
- Cool the wort.
- Transfer it to a sanitized fermenter.
- Pitch yeast.
- Ferment completely.
- Bottle or keg.
- Condition and taste.
The simplicity comes from the ingredient selection, not from skipping important brewing steps.
What Yeast Should You Use for SMaSH Brewing?
If your goal is specifically to study malt and hops, a relatively neutral yeast can help keep the focus on those ingredients.
A highly expressive yeast may produce fruity esters, spicy phenols, or other fermentation characteristics that make it harder to isolate what you're tasting from the malt and hops.
That doesn't mean expressive yeast is wrong.
It simply introduces another variable.
For your first ingredient-focused SMaSH experiment, keeping fermentation relatively clean can make comparisons easier.
Are SMaSH Beers Only for All-Grain Brewers?
No.
The basic concept can also be adapted for extract brewing.
Instead of using a single base grain, an extract brewer can use one type of malt extract and one hop variety.
The experiment isn't identical to an all-grain SMaSH beer, but it follows the same educational principle:
Reduce the number of ingredients so they're easier to understand.
This makes the homebrew SMaSH beer concept an approachable way for newer homebrewers to experiment without immediately moving into all-grain brewing — the educational principle stays the same regardless of method.
How Can SMaSH Brewing Help You Learn Hops?
One of the best ways to use SMaSH brewing is to repeat the same recipe while changing only the hop.
For example:
Batch 1: Base Malt + Hop A
Batch 2: Base Malt + Hop B
Batch 3: Base Malt + Hop C
Keep everything else as consistent as possible.
When you taste the finished beers side by side, differences become much easier to identify.
This same concept is why single-hop beers are valuable for learning hop varieties.
Craft a Brew describes its Single Hop IPA as a way to compare hop varieties and understand how each changes aroma, flavor, and bitterness.
Can You Use SMaSH Brewing to Learn Malt?
Absolutely. A single malt beer experiment is one of the best ways to understand how base grain choices affect the finished brew. Simply keep your hop and yeast consistent while brewing several batches with different malts.
You could compare:
- 2-Row
- Pilsner
- Vienna
- Maris Otter
Then taste them side by side.
You'll begin noticing differences in:
- Breadiness
- Toastiness
- Malt sweetness
- Color
- Body
- Aroma
This type of controlled comparison can help you understand why different beer styles call for different malt foundations.
What Beer Styles Work Well for SMaSH Brewing?
SMaSH isn't necessarily a traditional beer style itself. It's a recipe-building approach.
However, some beers lend themselves particularly well to simplified recipes.
Examples include:
- Pale ales
- IPAs
- Blonde ales
- Light ales
- Simple lagers
Hop-forward pale ales and IPAs are especially useful when your primary goal is exploring hop character.
Craft a Brew's Single Hop IPA follows this same principle by using a restrained malt foundation to put the selected hop front and center.
How to Design a SMaSH Experiment
If you're brewing primarily to learn, treat your batch like an experiment.
Change One Variable at a Time
If you're comparing hops, don't also change the malt and yeast.
Keep Brewing Conditions Consistent
Try to maintain the same:
- Batch size
- Water
- Mash temperature
- Boil time
- Yeast
- Fermentation temperature
- Conditioning time
Take Notes
Write down what you notice about:
- Aroma
- Flavor
- Bitterness
- Malt character
- Body
- Finish
The more consistent your process is, the easier it becomes to understand what changing one ingredient actually did.
Common SMaSH Brewing Mistakes
Choosing Ingredients That Don't Work Well Alone
Some specialty malts are intended to complement base malt rather than make up an entire grain bill.
Choose a malt that can properly serve as the recipe's foundation.
Changing Too Many Variables
The educational benefit disappears if every batch uses different malt, hops, yeast, temperatures, and brewing techniques.
Change one ingredient when comparing batches.
Assuming Simple Means Boring
A SMaSH beer can still have plenty of complexity.
Different hop addition times alone can create layers of bitterness, flavor, and aroma from a single variety.
Ignoring Fermentation
Even a simple recipe can produce poor beer if fermentation temperature, yeast health, or sanitation aren't handled correctly.
The Brewing Guides can help reinforce the fundamentals while you're experimenting.
Final Thoughts: What Is a SMaSH Beer?
A SMaSH beer is one of the simplest ways to understand what individual brewing ingredients actually contribute.
By using a Single Malt and Single Hop, you remove many of the competing flavors found in more complicated recipes. That makes it easier to identify malt character, hop bitterness, flavor, aroma, and the interaction between the two.
Once you understand those ingredients individually, building more complex recipes becomes much more intentional.
FAQs
What does SMaSH stand for in beer?
SMaSH stands for Single Malt and Single Hop, meaning the beer is brewed using one malt variety and one hop variety.
Is a SMaSH beer an IPA?
Not necessarily. SMaSH describes the recipe structure rather than a specific beer style. However, pale ales and IPAs are popular choices because they can showcase hop character clearly.
What's the best malt for a SMaSH beer?
Base malts such as 2-Row, Pilsner, Pale Ale, Vienna, and Maris Otter are common choices because they can provide the fermentable foundation of the beer.
What's the best hop for a SMaSH beer?
There isn't one best hop. Choose a variety based on what you want to explore. A versatile hop that works for bittering, flavor, and aroma can make an especially useful SMaSH experiment.
Is a single hop beer automatically a SMaSH beer?
No. A single hop beer uses one hop variety but can still contain several malts. A SMaSH beer specifically uses one malt and one hop.
Are SMaSH beers good for beginner homebrewers?
Yes. In beginner homebrewing, it can be hard to know what each individual ingredient is contributing when a recipe contains several malts, hops, and adjuncts. SMaSH beers solve that by reducing the variables. Their simple ingredient lists make them especially useful for learning how malt and hops influence a finished beer without as many competing flavors to sort through.
Start Brewing with Confidence
SMaSH brewing turns your next batch into a hands-on lesson in beer ingredients. Start with one malt and one hop, take notes on what you taste, then change a single ingredient in your next batch to begin building your understanding of recipe formulation.
