A PROJECT ?
Yeast is often described as the brewer’s invisible worker: it is what transforms wort into beer, produces the aromatic profile (esters, phenols) and determines attenuation as well as clarification speed.
For a craft brewery, the choice of yeast type and packaging directly impacts your cost per batch, the productivity of your fermentation area, and the level of sanitary risk in the conditioning cellar.
Between the practicality of dry yeasts (in 100 g sachets or 500 g bricks), the responsiveness of budget‑friendly ranges and the aromatic potential of liquid yeasts, each format serves a specific production strategy.
To equip your brewery, explore our full catalogue of professional yeasts.
1. Dry yeast vs liquid yeast: The operational trade‑off
Even before selecting the strain or brand, the first technical decision is the packaging format of your yeast:
A. Dry yeast (The reliability and productivity standard)
Available mainly in professional 500 g bricks or 100 g sachets, rehydratable or direct‑pitch dry yeasts dominate the craft beer industry.
- Strengths: Extremely long shelf life (several years), thermal stability during transport, easy gram‑accurate dosing, and zero prior preparation. They allow immediate pitching without the infection risk associated with propagation.
- Weaknesses: None. If the range was once relatively classic compared with liquid yeasts, the trend has clearly shifted over the past few years.
B. Liquid yeast (High‑end aromatic signature)
Offered in our range of professional liquid yeasts, these living strains deliver a highly complex organic profile.
- Strengths: An exceptional catalogue of heritage strains (traditional Belgian, specific Kveik, rare lagers or sour beer strains).
- Weaknesses: Limited lifespan, strict cold chain and process constraints: given professional brew volumes (several hectolitres), inoculation requires a substantial starter (propagation) beforehand to reach the required viability and pitching rate, which demands dedicated equipment (propagator, Erlenmeyer/propagation tank) and working time.
2. Comparison of dry yeast brands and ranges
To optimise your brewery’s profitability while maintaining an impeccable level of quality, we have selected several brands tailored to specific needs:
| Brand / Range | Positioning & strengths | Ideal usage profile |
|---|---|---|
| Fermentis & Lallemand (Standard ranges) | The historic global benchmarks. Certified direct pitching, maximum viability, alcohol tolerance and flawless batch‑to‑batch consistency. | For your entire permanent range (“Core Range”), your IPAs, precise lagers and specialty beers requiring highly defined profiles (e.g. US‑05, SafAle S‑04, LalBrew Verdant IPA). |
| WHC Lab | Outstanding value for money. Modern strains strongly focused on aromatic biotransformation and contemporary IPA styles. | Ideal for reducing production costs on hop‑forward recipes (Saturated, Mango Madness, Haze Heaven...) without any compromise on aroma. |
| Lallemand Essential | Ultra‑economical range with high performance on classic and standard profiles. | Designed to minimise the production cost of high‑volume beers where yeast should step back in favour of malt and hops (though not only). |
| Brewline | Economical French brand. Combines attractive pricing with geographic proximity (supporting the national supply chain). | Perfect for breweries looking to optimise margins while highlighting a French sourcing approach. |
3. 100 g vs 500 g format: Stock management and dosing
The size of your dry yeast packaging must be aligned with your fermenter volume to avoid waste and maintain perfect cell viability:
- 500 g format (vacuum brick): The quintessential economical format for breweries running 5 hL, 10 hL, 20 hL or larger batches. At a standard pitching rate of 50 to 100 g/hL (depending on wort gravity and ale or lager fermentation type), one or two 500 g bricks perfectly cover the volume of a full fermenter.
- 100 g format (professional sachet): The flexible choice. Ideal for small brewhouses (1 hL to 3 hL), pilot batches, precise adjustment of pitching rate (e.g. adding 100 g for a very dense wort) or for specialty strains used occasionally. Once opened, a yeast sachet quickly loses viability: the 100 g format prevents having half‑used 500 g bricks sitting in the fridge.
Rolling Beers Pro Technical Team Insight
Calculate your pitching rate precisely to avoid sluggish fermentation! Under‑pitching wort to “save yeast” is a risky calculation: it increases lag time, encourages bacterial infections and generates off‑flavours (undesirable ester notes, diacetyl, off phenols). As a general rule for dry yeast, count 50 to 80 g/hL for a standard ale (OG < 1.060), and increase to 100 to 150 g/hL for low‑temperature lagers or very dense imperial stouts. Adjusting your purchases between 500 g bricks and 100 g sachets lets you strictly respect these ratios without ever leaving an opened sachet to oxidise in the fridge!
