SKU# Y3787

Flat Rate Shipping only $7.99 only from Northern Brewer

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 Cold Ice Packs with all liquid yeasts. However, it is difficult to guarantee that the ice packs will survive the trip, given transit times and particularly hot temperatures.

Voracious, complex
I tried this strain with a patersbier (OG=1.056) and a very simple malt bill to highlight the esters. Pitched without a starter into oxygenated wort and fermented at 66-68 degrees. A big blow-off tube was necessary and even then, the krausen climbed up the tube a fair bit within 48 hours. It was finished fermenting within 5 days or so. But, leave it longer to clean up the considerable sulfur this strain emits. I'd say it needs a couple of weeks before kegging or bottling, maybe 3. Complex fruity esters with some minor phenols as well.

One of the best yeast strains
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.

Sourdough of Beer yeasts!
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!

Go-to belgian yeast
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.

A Robust Yeast!! Wowsa!
I used this yeast to brew the Le Petite Orange. The first time I used the Wyeast 1214 Belgian Abbeybut 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.

My go-to Belgian Yeast
I nearly always go with 3787 now unless I'm going for a traditional style. It is best to start lower, at 68, and let it rise normally, but its much more forgiving with the off flavors when its too warm inside the house and the fermentation temps go too high for comfort. Never too much of the overly sweet or funky flavors, not much of the weird banana smells, more subtle and spicier.

Nice Complexity
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.

My Favorite
Love the flavor that this yeast imparts. I've brewed a Tripel and a number of Patersbier kits with it.

Prompt delivery of needed yeast
When we realized that the yeast we had on hand was too old, a quick order from NB got us set up and going again. Thanks NB!

Anyone ever tried this yeast in a saison? Was going to wash and reuse as I just used this for a tripel. Thoughts?

BEST ANSWER: That should be perfectly fine, and not inappropriate. On the Wyeast site, the 3787 lists some styles of beer it is good for, and one is Bier de Garde, which is very close to a Saison. This will be a fine choice to ferment a Saison, I'd say go for it! -Mike W, Northern Brewer
