English Mad Mild

Fermentification

So you like beer but feel trapped in a world of high ABV extreme craft brews? Me too. I've been on a very brief quest (barely left the Shire) for a good low ABV beer to accompany days of lawn mowing, snow shoveling, etc.

After cruising around the forums at HomeBrewTalk.com I came across this little recipe from a poster named Orfy. His Mild Mannered Ale has received 33 pages(!) of reviews and recommendations. I decided it's a shoe-in for my next brew. Low ABV beers also lend themselves well to the Brew In A Bag (BIAB) method so it works well with my small setup. Let's get on with it, shall we?

Mad Fox's Ale Yeast

My first step on my low-ABV journey led me to Mad Fox Brewing Company, in Falls Church, VA. I've been enjoying their <4% Mason's Mild for some time now and ordered one on a particular Saturday in November. Fortune smiled upon my wife and I when our server asked if we'd like a behind-the-scenes tour of the brewery. Hell yes!

Our tour guide, Charlie Buettner, asked if there were any homebrewers in the crowd and I sheepishly raised my hand. I had been brewing for about three weeks at this point and could barely tell a ball valve from a bung hole. Charlie mentioned they regularly dispose of 40lbs. of yeast per batch and would rather give it to homebrewers than dump it down the drain. After taking him up on this offer I went home the proud parent of billions of little ale yeast cells.

The Grist + Willamette Hops

Now with an English yeast in hand and most of the ingredients in inventory it was time to craft a recipe. I was able to obtain all of the grains from my local homebrew store but had to substitute Willamette hops for the Fuggles called for in the recipe. Since I've never used an English style hop before I imagine I won't taste much difference.

After noticing a bit too much trub in the fermenter from my last brew I decided to increase the mill gap to 0.028" from 0.025". The BIAB method lets me use a finer crush than a traditional mash and lauter system because there's no worry of stuck sparges.

Makeshift Mash Tun

The BIAB method isn't all upsides though. One problem we have with this method is retaining heat during the duration of the mash period since the brew kettle serves as our mash tun. One great suggestion I found online was to wrap the brew kettle in an old sleeping bag (remove from stove first...).

Over the course of the 60 minute mash I lost only four degrees and that includes stirring the mash every 15 minutes. This brew was mashed at 158 degrees to promote a more dextrinous wort to give this low ABV mild a little substance.

Fancy Cooling System

After mashing I ended up with a pre-boil gravity of 1.048, waaaay over what I was shooting for with this 1.037 OG mild. Future brews will need to account for these epic ~95% BIAB efficiencies. After calculating a 1/2 gal. water addition during the chill phase I ended up with a 1.037 OG on the money! That also helped reduce my chill time which is pretty... chill.

At the end of the day my 4 gal. recipe ended up yielding 5 gal. after overestimating evaporation and low-balling my efficiency estimate. Free beer!

2/2/2013 - Pulled a sample to test gravity. SG is 1.013. Mash temp was a little high so not surprised if this is about as low as it gets. Plan to bottle next weekend regardless. Tastes pretty good, a little chocolaty and sweet. Julie detects a coffee aftertaste but she's a coffee bloodhound.

2/10/2013 - Pulled a sample. SG reading 1.012.

2/16/2013 - FG finished out at 1.010. Collected 4.75 gal. from carboy, yielded 47 bottles. There was a lot of flour/grit on the side of carboy after racking. Probably need a coarser grind. Not much appeared to transfer into the bottling bucket though. The roasty finishing character mellowed out a bit. Julie finds it a little more pleasing. I'm leaving these bottles on the main floor where it's a little warmer for one week to carbonate then plan to cellar.
