Wyeast | 1084 Irish Ale | Beer Yeast | Activator Smack-Pack System™ | 100 Billion Cells

    Description

    • 1084 is a versatile yeast that ferments extremely well in dark worts. It is a good choice for most high gravity beers
    • Low temps produce a dry, crisp profile with subtle fruitiness. Fruit and complex esters will increase at temps above 64°F
    • 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

    This versatile yeast ferments extremely well in dark worts. It is a good choice for most high gravity beers. Beers fermented in the lower temperature range produce a dry, crisp profile with subtle fruitiness. Fruit and complex esters will increase when fermentation temperatures are above 64°F (18°C).

    Attenuation: 71-75%
    Flocculation: Medium
    Alcohol Tolerance: 12%
    Optimum Fermentation Temp: 62-72°F
    Cell Count: 100 Billion
     

    Styles:

    • American Barleywine
    • Baltic Porter
    • Dry Stout
    • Foreign Extra Stout
    • Imperial IPA
    • Irish Red Ale
    • Oatmeal Stout
    • Other Smoked Beer
    • Robust Porter
    • Scottish Export 80/-
    • Scottish Heavy 70/-
    • Scottish Light 60/-
    • Spice, Herb, or Vegetable Beer
    • Strong Scotch Ale
    • Sweet Stout
    • Wood-Aged Beer

      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.

        Stopped fermenting

        I’m y sure what happened but my wort bubbled a little for about two days and then stopped. I just pitched more yeast (dry yeast). I’m not sure if I did something wrong but this is the first time I’ve had a wort that just will not ferment.

        Tight Yeast

        With proper brewing techniques this yeast settles out quick and forms a firm yeast cake that does not disturb easily. Makes Commercial clear bear without any finings.

        Great quality yeast

        This was my first time using a smack pack but once I understood how to locate the internal pouch and break it open the rest was a breeze. I much prefer the constancy of this over WL's Pure Pitch which is very thick.

        Strong fermentation

        Good to go without starter (although others recommend). Had a good week long fermentation that started within the first 12 hours.

        Seems fine

        I made a starter with it which seemed to ferment and grow normally. I haven't yet tasted the first batch (an Irish Red Ale) that I'm fermenting with it but it is about ready to bottle. I've used it in the past and think it is fine for stouts and some other styles. A minor disappointment is that I liked the old graphic on the Wyeast packs which showed a lovely colorful view of Mt. Hood a lot better than the new one.

        Favorite Yeast For Stouts

        I've brewed a few different stout recipes using this yeast and have been very happy with all of them. This yeast really gives a nice balance to a stout and just enough yeast character to let you know it's there. It doesn't over attenuate your stout which really adds to the nice full mouth feel that I enjoy, but still has a crisp finish. If you like rich full bodied stouts, this is a yeast you should try.

        First liquid will never go back

        Used with an Irish red being my first time using liquid yeast i did not know what to expect. It swelled up after only 3 hours and added far more complex flavor to the beer my previous batches with dry yeast could not compare too

        Will use again

        I used this on an Oatmeal Stout and was very stoked with the outcome. Gave an outstanding dry mouth feel that really changed one of my longtime recipes for the better. If you ever want to change up a stout recipe, definitely give this a go.

        Fantastic Yeast

        Brewed an Irish Red, that actually turned brown because I messed-up the grain bill, but flavor is excellent. Will use this yeast again !

        Stout

        I just used this and drank my first glass of stout tonight. It has great flavor. I have used four different yeast in the same basic stout recipe and this is by far my favorite. It came in a smack pack that swelled quickly. I had strong fermentation within 12 hours. I will use it again.
