I’ve recently been experimenting with making sourdough breads. Now, while I haven’t perfected it to the point of blogging (hopefully that will come soon) I have made some tasty product. However, for every one success, there are probably three failures. Personally, I hate wasting food, especially failed cooking experiments. While I was pondering what to do with the bread besides trying to compost it, I remembered the relatively obscure Russian beer kvass.
Classically, a kvass is a low alcohol beer brewed from old rye bread. The bread is mashed and the resulting slurry is fermented and consumed in a thick, often lumpy, smoothie. In more modern variations, the bread is separated from the sugary liquid and then the resulting wort is fermented. Being low in alcohol and before the time of “modern” brewing, it is likely that kvass developed a level of sourness after only a few days. It makes sense that a sour dough bread, having had lactobacillus already sour the mix, would be a perfect choice for a more modern take on the classic Kavas.
In order to extract as much sugar from the wheat as possible, I mashed with a bit of brewers malt just to make sure that the enzyme level was high enough. I had relatively poor control over the mash temperature so the temp ranged from the mid 150s to the low 140s. After an hour I did a quick sparge and then squeezed the brewing bag to extract a fair amount of liquid. I then boiled for an hour with a single bittering hop addition.
I wanted to take this one step further. Since this beer is about as far from Reinheitsgebot as you can get, a bit of experimentation was in order. I chose to make this beer into an herbal beer, adding thyme and basil to complement the bready characteristics. I wanted the beer to remind the drinker of bread sticks and salad (sounds a bit weird, but its a combo that has worked for Olive Garden for years). Going above and beyond I wanted to see what this beer tasted like in both a “clean” and “soured” form. One gallon went to a clean German wheat fermentation, the other went onto some jolly pumpkin dregs I had kicking around the house.
Recipe: San-Fran Kvass
Weird… Yah, Tasty… depends on who you ask. The clan version is very pleasant, with a freshly baked bread flavor and a hint of herbs on the finish. It only has a mild level of sourness, just enough to give a slight twang on the tongue. Overall, it is dry and refreshing, perfect after a day under the sun! The sour beer will be ready in a few months and will hopefully be drinkable. This modern take on a Russian kvass brings together San Francisco sour dough flavors with a nice basil and thyme backbone. At such a low, ABV this is a good session beverage which has a sour tang without the need to mess with sour bugs…. unless you want to.
