Lambic and Wild Ale

Cantillon is among the most traditional of lambic breweries but that has not deterred this family-owned brewery from offering a wide range of different beers.  One of the most unique and innovative year round beers is Iris. Iris stands out from the other Cantillon beers because it only uses malted barley instead of the traditional combination of malted barley and unmalted wheat.  The use of 50% fresh hops is another major difference from traditional lambic. The result is a real spontaneously fermented beer that is not a lambic (a true rarity).

Cantillon’s Cuvee des Champions is a special cuvée that is dry hopped in the cask for three weeks using Styrian Goldings hops. It is a blend of different lambics, but, unlike traditional Geuze, only two year old lambics are used, producing the characteristic soft pallet of the Cantillon Lou Pepe series.

As can be seen in the photo on the right, the elimination of wheat from Iris produces a darker color than traditional lambics. This difference was also reflected in the taste; Iris had a “heavier” ale-like caramel flavor. Although fresh hops were utilized in both beers, the smell and taste of hops was a lot more pronounced in Iris, which appears to reflect the fact that  in Cuvee des Champions the use of fresh hops was confined to dry hopping.  As a matter of fact, the use of fresh hops was hard to detect in Cuvee des Champions (perhaps this difference would have been clearer if this beer was compared to a traditional Geuze). Iris also had a stronger “barnyard” brettanomyces smell, a heavier mouthfeel, more  tartness, more astringency, and a longer finish than Cuvee des Champions, which was noticeably milder with less carbonation and more prominent citrus notes. Both beers are well executed, leaving the choice between the two styles a matter of personal preference. Cantillon’s Iris is a fine example of what spontaneous fermentation can achieve in other beer styles. 

Brettanomyces and hops are a predictable element in traditional lambic brewing but, as a general rule, the hops are not allowed to contribute to the flavor of the beer. One exception to this rule is Cantillon Iris, which does not contain wheat and includes fresh hops. As such, Cantillon has wisely decided not to label that a lambic beer. Another example of a beer that combines the Brettanomyces yeast and hops is the classic Trappist ale Orval.  But what can we expect from an experiment to combine Brettanomyces and American West Coast style hopping?

Signature Ale was conceived by the Port Brewing Company and De Proefbrouwerij in 2007 to find out. This  limited American / Belgian collaboration uses Sacchromyces and Brettanomyces and Amarillo, UK Phoenix, and German Brewers’ Gold hops during the boil and dry hopping. The result was released in 750 ml corked bottles.

The following notes were taken on Friday, March 27, 2009.

Poured into a snifter.

Appearance: Golden orange color. Substantial amount of yeast in bottom of bottle before pouring, resulting in a little yeast in the glass. 1.5 fingers of foam with some head retention and lacing.

Smell: Brett, pronounced orange smell, and citrus hops. Sweeter and more expressive when it gets warmer, but no element ever runs amok.

Taste: The malt, Brett and hops are in perfect harmony throughout. Ends on a velvety, hoppy finish. Warm and boozy.

Mouthfeel: Medium-bodied, nice carbonation, smooth, and creamy.

Drinkability: Smooth sipper. Beer changes with temperature, but is incredibly well integrated at every temperature. At 8.5% alcohol, this beer definitely packs a punch…take a taxi home!

Can one use Brettanomyces for beers that are not sour? I had an experimental 100% Brett beer once and was seriously underwhelmed, having to poor a portion of it down the drain. So it is fair to say that this beer was approached with some degree of caution. I am therefore glad to report that Signature Ale is absolutely stunning. The malt, brett and citrus hops present themselves in a beautiful balance. Finding a note that is off, even at different temperatures, is impossible.  This drinks like a strong but subtle Imperial IPA with the warm and introvert feel of a good Belgian Trappist Triple. This creation should not leave any remaining questions about the use of Brettanomyces for strongly hopped beers. A remarkable achievement.
