How do you folks finish your Belgian trappist-like beers? Cold crash? Gel fine? Bottle? Keg? This is how Rochefort does it: “Secondary fermentation lasts a rather short two or three days in horizontal lagering tanks, with yeast and sugar added after centrifuging.” (BLAM)
Not sure whether a force carbonated trappist ale will not be frowned upon if I submit one to a competition in BE/NL…
In Belgium, refermentation in the bottle is considered a sign of quality for trappist like beers. There are some exceptions, such as Westmalle Dubbel, which is also served on draft. But force carbonation in the bottle is a big no, as there is no more evolution over time.
I lager for a brief period of time. Ideally I would lager for much longer but it isn’t convenient in most situations to have to reyeast those beers. I’ll take a little extra yeast in the bottle over having to work up a fresh starter of yeast at bottling.
Maybe clear, force carbonate to 2/3 the desired volumes CO2 then bottle with enough sugar to get that last third. Then it’s ‘refermented’ without too much crap in the bottle.
I think bottle conditioning is more about quicker, efficient carbonation and conditioning than about any kind of flavor contribution.
Once the beer has reach terminal gravity, the reintroduction of yeast at bottling isn’t going to impart a flavor element so much as it will serve as reinforcement for the “fallen soldiers” used in the primary fermentation.
Cheap champagne yeast here should be more than sufficient.
Yes, I think so. I’m assuming by “evolution” we are talking aging, smoothing out of flavors, etc. These sorts of things happen with big Stouts, Barleywines, etc. without the introduction of bottling yeast. I don’t think the Trappists or other Belgian Brewers in the same vein have anything different going on.
Aging and blossoming along with suppression and mellowing of certain flavors occurs in beers with and without the addition of additional yeast at bottling.
This is merely a matter of utility for many of these breweries. They have tons of fresh primary yeast at their disposal. It isn’t used because of special flavor characteristics.
Also remember that most of the Trappists filter, condition or centrifuge the old yeast out before bottling to clear the beer. Adding new yeast is a necessity, not necessarily an attempt at flavor complexity.
There will still be plenty of yeast in suspension to get the carbonation job done, even after extended lagering. If it’s high gravity, you may want to add a bit of neutral yeast at bottling for insurance.
