Slight residual diacetyl and fruitiness; great for stouts. Clean, smooth, soft and full-bodied.

Customer Reviews

Use in IPAs Review by Adam
I was first switched on to this strain a few years ago and was impressed by its volcanic nature (don't ferment too warm). Because I enjoy slightly soft IPAs with a dry, malty backbone, this is my go to strain. If you like using tons of fruity hops in your IPAs and want a yeast to compliment the hop aromas/flavors, look no further than the 1084. This strain also bottle conditions well, as it leaves a tightly compacted cake. (Posted on 8/28/14)
great yeast for a stout Review by Brett
I just brewed a cream stout using this yeast (while creating a 2L starter). This ferments quickly and aggressively at easy to maintain temperatures. I would highly recommend this strain for most stouts. (Posted on 1/14/14)
Awesome Review by Tom
Very easy to work with. Always arrives fresh and in good condition. Also comes with freezer pack to make sure the yeast inside isn't spoiled. Great! (Posted on 1/5/14)

Great yeast Review by RJ
The best beer (NB- Irish Draught) i've made included this yeast.

I've used it two other times with stouts and the beer had a great taste. Go for it. (Posted on 11/6/13)
Solid Performer Review by Chris
Used it in a specialty grain packed Sweet Stout 1.072 OG without a separate starter and it was down to 1.021 in just over 5 days. Fermented on the higher side of things (69 deg) yet still remained clean without too much of the fruity esters common other strains. Sample at bottling had excellent body and was rich and smooth.

Nice, aggressive fermentation Review by Stuart
This yeast ferments aggressively, quickly, and cleanly. It leaves behind very mild esters so use in a porter or stout is ideal. Made a pumpkin porter with this and it turned out awesome. (Posted on 10/14/13)

Great for Stouts Review by Patrick
Great yeast for the Stouts I've made. (Posted on 8/17/13)
Very nice yeast Review by Max
I used this yeast in a Dry Irish Stout. It worked as advertised and it has a great flavor as of one week of conditioning prior to carbonating. (Posted on 7/14/13)
excellent yeast Review by Chip
Though the final product is still bottle aging, the "sample" I have had for Quality Control prove that this was the perfect yeast for what I brewed - a milk stout. Easy to use and great results. Looking forward to many more batches! (Posted on 7/12/13)
Excellent yeast for any Irish ale style. Review by Charles
I have used this yeast in four different batches and this yeast attenuates well, clears perfectly and creates true to form Stouts and Irish Red Ales. I will continue to purchase this item for many more batches. (Posted on 5/8/12)
Used several times Review by sol
Used this strain several times on classic dry irish stouts. Ferments in 3-4 days compared to 7-10 days for most ale yeast I am used to. My best stout I ever made was with this yeast fermented i the low 60's. Granted my experience is limited, but this yeast has done me a solid every time. (Posted on 1/6/12)
