If you’ve ever stood in front of the beer section wondering what really separates an ale from a lager, you’re not alone. The difference isn’t just about taste or colour — it starts deep in the brewing process and shapes everything from aroma to mouthfeel.
At MacLean’s Beer, we brew both. Whether you’re sipping a smooth Cherry Porter, a crisp Light Lager, or a bold Pale Ale, each beer tells a different story. Here’s a complete guide to understanding what makes ales and lagers unique — and why both deserve a spot in your fridge.
The Key Difference: It’s All About the Yeast
The main thing that separates ales and lagers is the yeast used during fermentation.
- Ales use top-fermenting yeast, which rises to the surface during brewing. This yeast thrives in warmer temperatures (15°C to 24°C) and produces complex, fruity flavours.
- Lagers use bottom-fermenting yeast, which settles at the base of the tank. It ferments slowly at cooler temperatures (7°C to 13°C), creating a smoother, crisper taste.
These differences affect not only the flavour but also the aroma, clarity, and even how long the beer needs to mature.
Brewing Process at a Glance
Ales are typically brewed faster — often ready to enjoy in a week or two — because of their warm fermentation. Lagers take longer, sometimes up to six weeks, as they ferment cold and need extra time to mature. This patient process gives lagers their famously smooth, clean finish.
Temperature, yeast, and time define the divide between these two beer families. Warm fermentation brings expressive flavours, while cold fermentation produces precision and balance.
What Is an Ale?
Ales are among the oldest styles of beer in the world. Their warm fermentation creates bold character, rich colour, and layers of flavour that stand up well to hearty meals and cool weather.
Common traits:
- Slightly higher alcohol content
- Notes of caramel, fruit, spice, or roasted malt
- Fuller body and rounder mouthfeel
Popular ale styles include:
- Pale Ale — balanced and hop-forward, like MacLean’s Original Pale Ale
- Porter — dark and roasted, such as MacLean’s Cherry Porter
- IPA — aromatic with pronounced hop bitterness
- Scotch Ale — smooth, malty, and warming for winter

What Is a Lager?
Lagers came later, first brewed in Europe’s cool cellars where the cold fermentation process naturally developed. The result was a beer that was lighter, clearer, and incredibly refreshing.
Common traits:
- Pale to golden colour
- Smooth, crisp, and balanced flavour
- Lower fermentation temperature and longer conditioning
Popular lager styles include:
- Pilsner
- Helles
- Amber Lager
- Light Lager, such as MacLean’s Premium Light Lager

Serving Tips for Ales and Lagers
Getting the most from your beer isn’t just about what you drink — it’s also about how you serve it.
Temperature
- Ales: 10–13°C — slightly warmer to bring out malt and fruit notes.
- Lagers: 4–7°C — colder to emphasise their crisp, clean finish.
Glassware
- Ales: Use a tulip, snifter, or nonic pint to capture aromas.
- Lagers: Choose a tall, narrow glass to keep carbonation lively and maintain the head.
Did You Know?
The word “lager” comes from the German lagern, meaning “to store.”
Early brewers kept their beer cool in caves or ice cellars, which naturally developed the smooth, refined style we now know as lager.
How to Pair Ales and Lagers with Food
Ales:
- Roast beef, lamb, or BBQ.
- Sharp cheeses, caramelised vegetables, or chocolate desserts.

Common Questions About Ale and Lager
What’s the easiest way to tell if a beer is an ale or a lager?
If it’s fruity, aromatic, or slightly heavier, it’s probably an ale. If it’s clear, crisp, and light-bodied, it’s likely a lager.
Is one stronger than the other?
Not necessarily. While ales often have higher alcohol content, lagers can be just as strong depending on the recipe.
Which is more popular in Ontario?
Lagers have long dominated Canada’s beer shelves, but the rise of Ontario craft brewing has brought ales into the spotlight, especially porters, IPAs, and pale ales.
Is lager always lighter than ale?
No. Some lagers, like amber or dark lagers, can be as rich and malty as many ales.
Which type of beer ages better?
Ales — especially stronger ones like Scotch Ale or Porter — often develop deeper flavours with time. Lagers are best enjoyed fresh for their crispness.
Can you enjoy both all year round?
Absolutely. Lagers shine in summer, while ales bring warmth and depth in the cooler months.
Two Styles, One Shared Craft
Whether it’s the fruit-forward depth of an ale or the clean refreshment of a lager, both styles reflect the art and patience of brewing. Each has its place — and at MacLean’s, we celebrate both.
