Description
  • 2124 is a Carlsberg type yeast—the most widely used lager strain in the world
  • Produces a distinct malty profile with some ester character and a crisp finish
  • Activator Smack-Pack System™ "proofs" the yeast and shortens lag time when it hits your wort
  • When smacked, the Activator™ packet releases sugars and nutrients to initiate the culture's metabolism
  • Wyeast has been a pioneer in craft brewing for over 35 years and is committed to creating the finest fermentation products available
  • Although beneficial, cultures do not need to be activated prior to inoculation

For best results we always recommend ordering an ice pack with your liquid yeast.

Please Note: When choosing an ice pack option beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.

Quick
I made a Czech Dark Lager with OG of 1.050. After 4 days it was at 1.015, I did a D-Rest for 2 days. Cold crash after 7 days. I would call that quick for lager yeast.

Arrive fresh. Pack it's swelled quickly. Fermentation fast start even at low temp. Looks like it will be an excellent beer.

Great Product
Consistent 75-76% attenuation. Leaves good body/mouthfeel w/ a beautiful but subtle dark fruit/floral aroma/flavor. Never any diacetyl in finished product but this dude does produce some major sulfur during fermentation. Aways, IME, cleans itself up though in 3+ weeks total ferment time. I LOVE this yeast.

Nice versatile yeast
Ferment at ale temps results in a fruity, but not overwhelming beer. Nice neutral flavor at lager temps.

First experience
First time with this strain. Starter was a little slow to take off and once pitched it was a little slow getting started in the fermenter. Once it got started, it moved right along, going from 1.072 all the way down to 1.010 in 5 days. It definitely lets the malt come through.
