Turbid Mash Lambic-Style Ale (In The Tradition Of Brasserie Cantillon)

Wild Yeast 03Months after we originally intended to, Gregory and I finally brewed our lambic-style ale on 09 February 2015.  We used Jim Liddil’s tek which is a conversion of Brasserie Cantillon’s turbid mash schedule to the homebrew scale.  Since we don’t currently have a barrel with neutral enough character, we opted to add French oak spirals to primary (we boiled the hell out of them beforehand so they wouldn’t overwhelm the beer).

We don’t have a koelschip and we didn’t let the beer spontaneously ferment per se, rather we chilled with a wort chiller as usual and pitched both of the batches of wild yeast that I harvested from my house (see my previous post).  We also overlooked the fact that our homebrew store wouldn’t have raw wheat and, as we were pressed for time, we just settled on regular wheat malt.  Though theoretically this could actually harm our efficiency because the wheat has already been well modified, the real goal here was to conduct the turbid mash, so we went ahead with it and did hit our intended gravity.

We have not yet decided if, when this beer is ready, we will serve it straight, fruit it, or blend it with a younger lambic-style ale to produce a gueuze-style ale; we’ll keep you posted.

Notes

02.09.15 — Cold crashed and decanted the growlers of wild yeast I propagated morning of brew day

Brewed on 02.09.15 with Gregory

02.09.15 — After a nearly eight hour brew day, chilled wort to 70F and pitched the wild yeast into a carboy with the oak spirals and put in on the brewbelt.

02.13.15 — Signs of fermentation activity

03.25.15 — Transferred off of the oak spirals into secondary fermentor and added the bottle dregs from Brouwerij Oud Beersel Oude Geuze

02.11.16 — Pulled a sample from the carboy and tasted it.  Lots of oak character even though we boiled the spirals for quite a while and changed the water numerous times.  Surprisingly not too much acidity/sourness yet, will probably pitch some extra bottle dregs soon.

Calculated OG: 1.048
