Your first lager versus your first ale and which to brew first

The difference is the yeast

Ales and lagers are separated by yeast, not colour or strength. Ale yeast works best at roughly 16 to 22 °C. Lager yeast prefers about 8 to 13 °C and works more slowly. Ale yeast is Saccharomyces cerevisiae. Lager yeast is Saccharomyces pastorianus, a hybrid species that is well suited to cold, slow fermentation. Our guide to ale versus lager yeast covers the biology.

That temperature gap drives everything else. Cool, slow fermentation leaves very few fruity esters, which is why a good lager tastes clean and crisp. Warmer, faster ale fermentation leaves more fruit and character.

What a lager asks of you

Brewing a lager properly means three things:

1. Cold fermentation at about 10 to 12 °C for two weeks or so, held steady.
2. A diacetyl rest, letting the beer warm to about 16 to 18 °C near the end so the yeast cleans up the butter flavour it made earlier.
3. Lagering, which is cold storage near 0 to 2 °C for several weeks while the beer clears and smooths out.

In a Delhi summer, or in Chennai at almost any time of year, none of these happen without a dedicated fridge with a temperature controller. A lager also needs more yeast than an ale of the same strength, often two packets of dry yeast for 20 litres.

Lagers hide nothing. A pale lager has so little to mask faults that any slip in sanitation, oxygen or temperature shows straight away.

What an ale asks of you

An ale needs a steady 18 to 20 °C for about a week, then a few days to finish. Indian homes rarely sit that cool either, but getting a fermenter down to 18 °C is much easier than holding it at 10 °C for weeks. A tub of water with frozen bottles can do it in the cooler months.

Ales also forgive more. A pale ale or a brown ale has enough malt and hop character that a small fault does not dominate. Most ales are ready two to three weeks after brew day, while a lager can take six weeks or more. In your first months, that means more batches and more chances to learn.

Our advice: ale first

For almost everyone, we say brew two or three ales first. You will learn the brew day, sanitation, fermentation control and bottling on beers that tolerate small mistakes. By the third batch, you will know whether your temperature control is good enough for a lager.

When you are ready, our guide to brewing a lager at home walks through the full schedule.

The shortcut: a lager-like ale

If you want something crisp and pale now, there are two well-known routes.

• A clean ale yeast at the bottom of its range. Some American and Kolsch-type ale strains ferment very cleanly at 15 to 17 °C. Pale malt, a little rice or maize for lightness, noble hops and a few weeks cold in the fridge after fermentation will get you something close to a lager.
• Kveik. These Norwegian farmhouse yeasts tolerate very high temperatures, often 30 °C or more. Some strains stay surprisingly clean. They are popular with homebrewers in hot countries. They will not taste exactly like a lager, but a clean strain makes a crisp, easy pale beer without any cooling at all.

Neither is a true lager. Both are good beers and both teach you skills that carry over.

What decides your answer

If you already own a spare fridge and a controller, go ahead and try a lager early. If you do not, brew ales until you do. Either way, avoid the classic first-timer error of fermenting a lager yeast at room temperature, which gives a sulphury, fruity beer that is neither style. Our list of common first homebrew mistakes has more.

The jump from ale to lager is mostly about control: of temperature, yeast count, oxygen and time. That control is the core of what we teach. Once you have it, the style you brew becomes a choice rather than a limitation.
