Thiols on Trial

Fermentis SH-45 MBAA Thiol Trial

Niagara Teaching College Brewery

4.1% Alcohol

Release the thiols!

Not the catchiest name I’ve seen for a beer. Certainly not up there with Juicy Ass or Sneaky Weasel (30% sneakier) that’s for sure. But the name appears to be the yeast of our worries. Time to break it down. Niagara College Teaching Brewery (NCTB) brewed a beer for the Master Brewers Association of the Americas (MBAA) conference. They used SafLager™ SH-45 yeast from Fermentis (by Lesaffre), a yeast that “possesses the capability to release and esterify thiols”, hence the name Fermentis SH-45 MBAA Thiol Trial. RELEASE THE THIOLS I say! What is a thiol you may ask. * Hell if I know but I’m about to quaff a glass full.

A light golden pour for a bordering on light lager. A nice dense bright white one finger (no not that finger) head which interestingly enough was there from start to finish. Malt hoppy aroma, reminiscent of a West Coast pils. First swig is malt sweet with some fruit and a very crisp dry finish and very dry aftertaste. It continues with a malt mild citrus touch of bitters crisp finish but not nearly as dry as the first swig, but still that dry aftertaste. As the bottom became closer to the top the fruit morphed into floral.  There were some twists and turns with this one.

I enjoyed the mild fruit malt combo and the pils like finish. Too bad some floral found it’s way into the experiment. All in all an interesting beer, if it could have maintained those nice early fruit notes it would have attained super suds status.

*Editor’s Comment: There are two families of compounds that can be released from hops. Thiols and Terpenes. Thiols exhibit fruity characteristics. According to Fermentis “In the hops, some thiols can be bound to cysteine or glutathione and the terpenols to sugar chains resulting in non-volatile and odorless compounds so-called “aromatic precursors”. The volatile aromas can then be released through the action of specific enzymes (beta-lyase for thiols, glyco- and glucosidases for terpenols and C13), their effect can be expressed by yeasts or bacteria. Terpenols are a little more complex as they can be also bioconverted by yeast (reduction and isomerization) into other terpenols and be naturally hydrolyzed in the right pH conditions. As a consequence, their concentration is indeed affected by the yeast but is quite complex to predict over time.”

*Reviewer’s Comment: Thanks for clearing that up for me.

Final Rating: The Verdict is a 14 out of 20
