Use Blow Off Tube
I have used this yeast twice this year, once for a 2.5 gallon batch of Tripel, brewed in July, and then bottle conditioned 4 months. It was a 10% ABV monster with lovely spicy phenolic yeast notes, grain bill, and hop additions were kept very simple to really let the yeast shine, and this turned into a favorite recipe I will be sure to repeat, it nailed Westmalle character. The other is a 5 gallon batch of Dubbel with holiday spices that will be getting kegged later this week and is currently in the fermenter. For both beers I made a starter the night before pitching, and in less than 24 hours after pitching, the yeast was at the top of the fermenter. Both times I barely caught it in time to make a makeshift blow-off tube, next time I'll set it up form the start. The Tripel started at 1.086 and fermented down to 1.008, and the Dubbel started at 1.070 and fermented down 1.012.This yeast flavorful, reliable, and aggressive, I would recommend this yeast all day everyday for any Belgian styles, and especially Abbey styles. Once last thing: before racking, cold crash your beer after fermentation completes, otherwise this yeast will stay in suspension. I would say the "medium" flocculation is a very low medium.

Trappist 3787
This is a very consistent Belgian yeast for high alcohol brews such as tripel and dark strong. This yeast gets off to a strong & quick start and ferments down to low gravity numbers. I have used this yeast many times and am very pleased. Provides some very good phenols as well and has that distinct Belgian flavor depending on the fermentation temperature you choose.

Ooooh yeah try me
This is my favorite for all around belg. Beers. best with less age. Some of these belg. yeast need the age to get that right flavor. Not this one. Tripels, dubbel in a month, boom drinky drinkie

This is certainly my number one favorite Belgian yeast and provides true and up front Belgian character.

one of my favorite yeasts of all time
Attenuates quickly and thoroughly. Not finicky, and adds a very nice Belgian yeast character without being difficult to use like others (think Belgian saison 3724?)

My Go-to Belgian Yeast
I have used this yeast 10 times at least. It is an excellent product for making Belgian ales. I usually go for the Belgian Strong Ale - formerly know as a Belgian Quadrupel. :-)
