Wyeast 3787 Trappist High Gravity

SKU: Y3787

Wyeast 3787 Trappist High Gravity strain is a robust top cropping beer yeast with phenolic character. Wyeast 3787 Trappist High Gravity beer yeast has an alcohol tolerance to 12%. It's ideal for Bière de Garde, as it ferments dry with rich ester profile and a malty palate.

We strongly recommend ordering dry yeast in the summer months. We do include complimentary ice packs with all liquid yeasts. It is difficult to guarantee that the ice packs will survive the trip given transit times and particularly hot temperatures.

Go-to belgian yeast Review by Ricker
I re-pitch this yeast on everything Belgian. A few months ago I brewed the Patersbier kit, washed the yeast, then threw it into a Blonde, a Petite Orange, a Dubbel, and a Trippel. It kicked off pretty quickly and led to a bunch of great beers. Highly recommend. (Posted on 7/29/14)
Total Workhorse Review by Jason
As the previous review wrote this is a vigorous fermenter. I used a starter for this yeast on a Belgian Tripel. It provided a great spice note to the brew and had great fermenting time. (Posted on 1/18/14)
solid fermenter Review by noah

Sourdough of Beer yeasts! Review by Christian
I love the complexity of flavors that come from this yeast. In the Patersbier kit, I'm continually amazed at the banana, clove, biscuit, and wild sweetness that are brought out from such a simple grain/hops bill. It's like making a sourdough bread in a bottle! (Posted on 12/3/13)
Great for high gravity without a starter Review by Thomas
I did a belgium dubbel this fall. It was a litte stronger than anticipated (10.90) and after two weeks in primary the gravity was 10.16. the final product was delicious and I received many compliments on the aroma and spice flavors of my beer. (Posted on 10/30/13)
My Favorite Review by Chad
Love the flavor that this yeast imparts. I've brewed a Tripel and a number of Patersbier kits with it. (Posted on 10/27/13)
Neutral flavor for Belgian yeast Review by Golden_Sky
This yeast was used in a Belgian Dubbel, fermented in upper 60's. Started slightly slow, but within 48 hrs had a krauesen forming. Primaried for 2 weeks, and secondary for 2 weeks. Final product displayed good malt tones with a dry yet silky finish and a little spice. I would gladly use again for a Belgian style beer that doesn't require too much of that good 'ol funk.
ps The first smack pack did not inflate after 48 hrs, so NB promptly sent me another which did its job well. (Posted on 10/1/13)
Trappist HG Review by Vincent

First time using this yeast Review by Mike
Used with the La Petite Orange Ale. Just bottled the beer so I'm not sure how it will affect the flavor, but have high expectations (Posted on 8/23/13)
A Robust Yeast!! Wowsa! Review by Henry T
I used this yeast to brew the Le Petite Orange. The first time I used the Wyeast 1214 Belgian Abbey
but that wasn't available this time. I created a starter and although it was slow to start-up, whew! I ended-up having to replace my fermentation lock with a blow-off hose. Figorous fermentation! I fermented at a controlled 64 degrees. I highly recommend this yeast. Very similar to 1214. (Posted on 8/14/13)
Blowoff Needed ! ! Review by Tom
This was my first liquid yeast, used it on the "La Petite Orange Dubbel". Had a 6.5 Gal carboy and temp control at 67* and thank goodness I had a blowoff, but unlike what i saw from others it only happened once. I also had to slowly ramp up the temp to get the last couple of gravity points. OG 1.058 FG 1.009

It took awhile for it to mature to taste like a proper Belgian. Started with a very strong sulphur smell while in primary, but it goes away after 4+ weeks bottle conditioning. (Posted on 8/8/13)
Classic Belgian Yeast Review by Brett
Vigorous fermenter. Great spicy ester notes classic Belgian flavor profile. Versatile as well, I've used this yeast for high gravity triples and for saisons. (Posted on 7/16/13)
Nice Complexity Review by Mike
I have not used this yeast for any "high gravity" beers, just the Patersbier kit where it is the recommended yeast and that has become one of my favorite beers ever! And the only thing that could contribute to the complexity of that kit MUST be this yeast since the list of ingredients is pretty sparse. I'm not a huge fan of the really heavy Belgian ales but now I'm curious to try one made with this yeast. (Posted on 7/14/13)
Great belgian yeast Review by Jason
Used on Patersbier all-grain kit. Beer fermented out quickly with no starter. Nice Belgian flavor profile. (Posted on 7/12/13)
Slow starter, good results Review by Jim B.
Do not be alarmed when this yeast fails to show any activity for the first couple of days. After 48 hours at ~72 F, it looked still. By the end of the third day there was the slightest hint of activity. By 96 hours there was full on active fermentation.

Used with the patersbier kit available from NB. (Posted on 7/2/12)
We will see Review by Tbreebo
Used a caribou slobber grain bill + 2 lb 2 row, 1lb of amber Belgian candy syrup hoping it comes out like a dubble hops Golding @ 60 & vanguard @ 15 with candy syrup and of course a yeast starter (Posted on 4/26/12)
One of the best yeast strains Review by Paulysci
3787 is a fantastic yeast. It ferments with robust flavor that isn't completely identifiable as "Belgian." Though robust, this yeast ferments to a silky smoothness that, combined with all that flavor, masks nearly all alcohol. This makes your beer much more drinkable than most... dangerously drinkable.

I used this yeast in a Belgian-style strong dark ale (9%). The beer came out perfectly. It fermented fully in 7 days and tasted wonderfully of dark fruits like black cherries, figs, plum/prunes, and a light maltiness I usually only find in English ales.

The second time I used this I used it in a strong mocha stout. I am a "dyed-in-the-wool" Guinness lover, and this beer is now my new favorite stout.

Use it once and your in love. (Posted on 3/9/12)
Great yeast for belgian spice Review by Brendan
depending on the temp you ferment, this can either give peppery, lovely spice, or turn out like a fine pilsner flavor profile, it is very diverse. I will say higher temps yeild a more belgian profile. (Posted on 1/23/11)
