If you’ve been looking for a dry version of the Conan strain of yeast… it’s finally here! The Conan Strain is used by Alchemist Brewing to ferment Heady Topper.
About: “LalBrewTM New England is an ale strain selected specifically for its fermentative consistency and its ability to produce a unique fruit-forward ester profile desired in East Coast styles of beer. A typical fermentation with LalBrewTM New England will produce tropical and fruity esters, notably stone fruits like peach. LalBrewTM New England exhibits medium to high attenuation with medium flocculation, making it a perfect choice for East Coast style ales.”
Classified as a Saccharomyces cerevisiae, a top fermenting yeast.
Typical Analysis of LalBrewTM New England Yeast:
Percent solids 93% – 97%
Living Yeast Cells ≥ 5 x 109 per gram of dry yeast
Wild Yeast < 1 per 106 yeast cells
Bacteria < 1 per 106 yeast cells
Finished product is released to the market only after passing a rigorous series of tests
*According to the ASBC and EBC methods of analysis
In Lallemand’s Standard Conditions Wort at 20°C (68°F)LalBrewTM New England yeast exhibits:
Vigorous fermentation that can be completed in 7 days, a bit slower than most ale strains. This is perfectly characteristic of this strain..
Medium to High Attenuation and Medium Flocculation.
Aroma and flavor is fruity and phenolic with a hint of alcohol.
The optimal temperature range for LalBrewTM New England yeast when producing traditional styles is 15°C (59°F)* to 22°C (72°F)
Lag phase can be longer compared to other ale strains, ranging from 24-36 hours
Fermentation rate, fermentation time and degree of attenuation are dependent on inoculation density, yeast handling, fermentation temperature and nutritional quality of the wort.
Depending on the desired gravity of the beer, among other variables, different yeast pitching rates should be applied. For LalBrewTM New Englandyeast, pitching rate varies between 100 grams and 100 grams of active yeast to inoculate 100 liters of wort.
A pitching rate of 100g per 100L of wort to achieve a minimum of 1 million viable cells per ml.
The pitching rate may be adjusted to achieve a desired beer style or to suit processing conditions.
LalBrewTM New England has an ABV tolerance of 9%. For beers above 9%, the yeast will require nutrient addition such as 1g/hL of Servomyces.
Rehydration of LalBrewTM New England is recommended for use, and will reduce osmotic stress on the yeast when rehydrated and pitched in liquid form. Rehydration guidelines are quite simple, and present a much lower risk of contamination than a starter, which is unnecessary with dried active yeast.
Sprinkle the yeast on the surface of 10 times its weight in clean, sterilized water at 30-35°C (86-95F). Do not use wort, or distilled or reverse osmosis water, as loss in viability will result. DO NOT STIR. Leave undisturbed for 15 minutes, then stir to suspend yeast completely, and leave it for 5 more minutes at 30-35°C. Then adjust temperature to that of the wort and inoculate without delay.
Attemperate in steps at 5-minute intervals of 10°C to the temperature of the wort by mixing aliquots of wort. Do not allow attemperation to be carried out by natural heat loss. This will take too long and could result in loss of viability or vitality.
Temperature shock, at greater than 10°C, will cause formation of petite mutants leading to long-term or incomplete fermentation and possible formation of undesirable flavors.
LalBrewTM New England yeast has been conditioned to survive rehydration. The yeast contains an adequate reservoir of carbohydrates and unsaturated fatty acids to achieve active growth. It is unnecessary to aerate wort upon first use.
When using Lallemand Brewing Yeasts, you may repitch the yeast just as you would any other type of yeast according to your brewery’s SOP for yeast handling.
LalBrewTM New England yeast should be stored dry below 4C° (39.2°F)
LalBrewTM New England will rapidly lose activity after exposure to air. Do not use 500g or 11g packs that have lost vacuum. Opened packs must be re-closed, stored in dry conditions below 4°C, and used within 3 days. If the opened package is re-vacuum sealed immediately after opening, yeast can be stored for up to two weeks below 4°C.
Do not use yeast after expiry date printed on the pack.
As of this posting, the only offering I’m aware of for LalBrew New England American Ale Yeast is a 500 gram offering via Brewcraft USA. 500 grams is a tough homebrew purchase, but could make sense for a group buy. Hopefully we’ll see homebrew-sized pitches of LalBrew New England soon.
