Tables – dontcha just love ‘em? I do, as you’ve probably already gathered. I really do have a thing about numbers. Can’t get enough of them.

You really wouldn’t want to see what goes on in my head. It even looks weird to me. But I’m digressing like a digressing stick.

My second look at the 2015 Bock crop is focused on top-fermenting examples. It’s a sign of the transformation of Dutch brewing that these greatly outnumber their bottom-fermenting counterparts. 63 to 29, if you’re interested. Though neither of those totals includes beers labelled Doppelbock.

Once again, a couple of the beers fall outside the parameters of a Dutch autumn Bok. Anything under 15º Plato is too low in gravity. And anything with a colour value below 30 is way too pale.

Though the two beers with the highest EBU value were both top-fermenters, there’s nothing to pick between the average bitterness of them and the bottom-fermenters. Most of the other averages are also pretty close, with the top-fermenters slightly higher in gravity and ABV. The biggest difference is in the colour, where the bottom-fermenters are significantly paler. Take a look:

I’m having arsing issues again so I’ll leave you with all the pretty numbers lined up neatly in rows.
