Brewing Beyond Standard: Bringing Something New to IPAs
When was the last time you drank an IPA that truly stood out? In the vast world of craft beer, the IPA has often fallen victim to brewing the "standard". It's tried and true — often with hops like Citra and Mosaic, and yeast strains like Foggy London Ale. This makes a great beer, no doubt, but the similarity between each brewery's iterations can be striking. At Escarpment Labs, we believe in pushing the boundaries, inspiring brewers to craft unique and exciting beers that stand out on tap lists.
But, how do we move beyond the standard? Different yeast strains are a great place to start! Try some of our suggestions below, and scroll further for the full breakdown of each strain:
- LalBrew Pomona™ — The peachy trendsetter
- TERPS — The citrus heavy hitter.
- Elysium — The pineapple ester sensation.
- Thiol Libre — The game changer for tropical thiol aromas.
- Hydra — "Hazies on easy mode"
-
House Ale — Versatile, clean, fast fermenting
---------------------------
1. LalBrew Pomona™
LalBrew Pomona™ is a hybrid yeast developed by our team at Escarpment Laboratories, selected for flavour and fermentation performance in hoppy beers.
Inspired by the goddess of fruit trees, LalBrew Pomona™ brings a deliciously unique and juicy flavour profile, with hints of peach, citrus, and tropical fruits.
Using advanced yeast breeding and some pretty cool science in our lab, we developed this strain to thrive in high ABV and highly hopped IPA fermentations. The result? A fruity, robust, and stress-tolerant yeast that adds incredible biotransformation and haze to your modern IPAs.
PRO TIP: Enhance Pomona's biotransformation by loading up the wort with precursors, ensuring that they carry over to the fermenter. You can also tailor a hop bill to complement the Geraniol (fruity/floral) into Citronellol( citrusy/floral) characteristics by using hops like Moteuka, Bravo, US Cascade, Mosaic, Soachi Ave, and Citra. LalBrew Pomona™ may also attenuate higher than other modern IPA strains, which is ideal for high gravity brewing!
Key Characteristics
- Attenuation: 75-84%
- Optimal Temp: 18-22ºC (64-72ºF)
- Biotransformation: Medium (Terpene flavouring)
- Flocculation: Medium
- Alcohol Tolerance: Medium (Up to 10%)
- Flavour Profile: Peach, Citrus, Tropical Fruit
2. TERPS
A recent addition to our yeast family, TERPS is your new go-to for your west coast IPAs with high citrus and mango flavour. We used the adaptive laboratory evolution method to train up the American Ale strain to transform more terpenes. Brewers can expect high efficiency and attenuation, plus stronger terpene biotransformation than Cali Ale or other conventional strains meaning brewers will get punchier hop aromatics.
PRO TIP: In particular, this strain pairs well with West Coast IPA hops (think Centennial, Chinook, Simcoe, and Citra) where it will transform geraniol (floral) into citronellol (citrus/lemongrass) and boost overall aroma impact of hops. We also find that terpene biotransformation combined with myrcene-rich hops and yeast esters produces a distinct mango perception in IPAs.
Key Characteristics
- Attenuation: 77-87%
- Optimal Temp: 16-22ºC (71-72ºF)
- Biotransformation: High (Terpene flavouring)
- Flocculation: Medium (Easy to Harvest, Repitch)
- Alcohol Tolerance: Medium (Up to 10%)
- Flavour Profile: Citrus, Mango, Orchard Fruit
3. Elysium
Strong pineapple esters and good flocculation define Elysium, offering brewers the advantage of faster turnaround times. Its balanced hop biotransformation profile makes it versatile, suitable for not only IPAs but also sours and more. Efficiency in fermentation and ease of harvesting make Elysium a valuable tool in the brewer's arsenal.
PRO TIPS: Looking to enhance the pineapple esters? Elysium can be fermented warm or with a free rise. A fermentation that starts at 22ºC and rises to 26ºC will maximize pineapple ester in Elysium. This yeast also has somewhat high nutrient requirements, so make sure it gets plenty of oxygen and Yeast Lightning. While this yeast has lower attenuation, you can add dextrose or Brewers Crystal to your wort to make it more fermentable, which can help with production of drier finishing West Coast IPAs using Elysium. Hop pairings to punch up the fruit include Amarillo, El Dorado, Citra, and BRU-1.
Key Characteristics
- Attenuation: 68-76%
- Optimal Temp: 18–26°C (64–79°F)
- Biotransformation: Medium (Terpenes and Thiols)
- Flocculation: Medium-High (Easy to harvest and repitch)
- Alcohol Tolerance: Medium (Up to 10%)
- Flavour Profile: Pineapple, Guava, Lemon
4. Thiol Libre
Unlock bolder tropical fruit aromas without the need for extra hops or adjuncts with Thiol Libre. Thanks to thiol compounds like 3-MHA, beers fermented with Thiol Libre boast enhanced guava and passionfruit aromas. This yeast option is a game-changer for brewers seeking an extra layer of aromatic complexity.
PRO TIP: Try using hops with high amounts of bound thiols, such as Cascade, Saaz, Calypso, and Perle. We recommend experimenting with your local hop farmer's Cascade! Use these in the mash (mash hopping) and whirlpool. Borrow a thiol release pro tip from Sauvignon Blanc white wine makers: ferment cool (17-18ºC) to retain more thiol aroma, with the tradeoff of a slightly slower fermentation. With Thiol Libre, you can go lighter on the dry hop.
Key Characteristics
- Attenuation: 68-80%
- Optimal Temp: 17–23ºC (63–73ºF)
- Biotransformation: Very High
- Flocculation: Medium
- Alcohol Tolerance: Medium
- Flavour Profile: Passionfruit, Guava, Grapefruit
5. Hydra
A genetic hybrid of Cerberus and Vermont strains, Hydra offers lower attenuation for a juicier flavour profile coupled with robust mango and citrus aromatics. Ideal for hazy, hoppy beers, Hydra addresses the challenge of hop creep, ensuring a balanced and flavourful IPA. Extra wort oxygenation is recommended for optimal performance.
PRO TIP: No need to adjust your mash regime! This low attenuating strain leaves plenty of residual sugars, which is perfect for hazies. If you are struggling with over-attenuated hazy IPAs and your brewhouse lacks the capability to do a mash out step to lock in fermentability, this strain is for you. Hydra will help keep those beers juicy even with over-active mash enzymes and some hop creep during dry hop. If you want a drier finish, you can control attenuation by substituting a percentage of your malt with simple sugars. We find this strain pairs exceptionally well with Strata, Mosaic, Chinook, Cashmere, and Centennial hops, all of which benefit from terpene biotransformation.
Key Characteristics
- Attenuation: 65-72%
- Optimal Temp: 20–25ºC (68–77ºF)
- Biotransformation: High
- Flocculation: Medium-Low
- Alcohol Tolerance: Medium
- Flavour Profile: Mango, Stone Fruit
6. House Ale EL-D1
Our dry active yeast strain, House Ale EL-D1, is the go-to option for those seeking neutrality, cleanliness, and balance. Adaptable to various recipes, it finishes fermentation and diacetyl/acetaldehyde cleanup efficiently, saving time in both fermentation and maturation. Highly repitchable, House Ale allows for easy experimentation across styles.
PRO TIP: House Ale EL-D1 is more neutral than the other options in this article, making it an excellent option to show off the natural character of your hops. You can use it anywhere you'd use a California ale strain. When used in a hazy IPA wort, it can also be used to make hazy IPAs although it is not haze-positive. This is the go-to strain for ramping up your beer production without worry in advance of the busy summer beer season. Hop pairings include highly aromatic hops that do not require much biotransformation, such as Citra, Mosaic, Galaxy, and Nelson Sauvin.
Key Characteristics
- Attenuation: 75-85%
- Optimal Temp: 16–22ºC (61–72ºF)
- Flocculation: Medium-Low
- Alcohol Tolerance: High
- Flavour Profile: Neutral, Clean, Balanced
