![]() ![]() ![]() “Craft beer is so big now that everybody who used to homebrew to brew styles they couldn’t buy are like, ‘Screw it, I can just buy it, ’” says Jimmy McMillan, owner of the Philly Homebrew Outlet, who just opened a second location in an underserved neighborhood to leverage steeply declining sales at his original spot. Industry insiders attribute the slump to various factors but the one they can least ignore is the one that’s most counterintuitive: the popularity of craft beer itself. There are legal limits of 0.2 g/L (Europe) and 0.3 g/L (America) the sensory level for perceiving this chemical’s flavor is reported at 0.135 g/L.Īdjusting these from sorbic acid -> potassium sorbate (what a homebrewer weighs) gives legal limits of 0.26 g/L and 0.4 g/L, respectively, with a taste threshold of 0.18 g/L.For all the predictions of a looming brewery shakeout, it looks like the homebrewing industry may actually suffer through it first. Winemakers talk more about sorbic acid, the relevant chemical potassium sorbate is 74% sorbic acid. Longer version How much potassium sorbate? Tl drįor each gallon of cider, use 1/2 tsp of potassium sorbate and 1/2 tsp of 10% sulfite solution (an extra step, but worth making – the solution is easier to work with than dry potassium metabisulfite). This guidance from BYO magazine on backsweetening provides background on the approach. The most common method in home cidermaking is to add both potassium sorbate and potassium metabisulfite (“K-Meta”). If you add sugar to hard cider and don’t want that addition to restart fermentation (which would increase alcohol and leave the cider even drier), you’ll need to stabilize it. I re-researched this every fall when it came time to backsweeten the previous year’s cider, so I wrote this guide to future me. In the meantime, what better substance to keep the barrel full and wet than beer? Even if that beer ultimately becomes too sour to drink. Whenever it again becomes possible to do another full empty/fill cycle, we will evaluate the barrel’s state. This beer will sit indefinitely, with participants having the option to extract 5 gallons of sour beer and swap in 5 gallons of fresh. We decided to switch to a solera project. Summer 2020 update: Due to COVID-19 it was not possible to empty and fill the barrel in summer 2020, an activity which requires several people in a close space. Brewers often perform a tertiary fermentation on fruit – tart cherries are a favorite, this being Michigan – and sometimes blend with young or clean beers to cut sourness to taste. Beers from this barrel have won silver and gold medals in the American Wild Ale category at the 2016 & 2017 Michigan Beer Cup. This barrel has produced consistently good beers and the sour character is now well-established. We typically aim to bring 11 shares of 5 gallons each, filling the barrel to the top and leaving some extra to top up the angel’s share. The brewers are a rotating cast, with people dropping in and out. We empty + refill every six months or so.
