I’ve done a decent bit of kegging this past week, to square away some beers slated for the Lake Arrowhead Brewfest that I’ll be serving with Horse Thief Brewers. The festival is just under a month away, but with a new baby soon to arrive in the household I know that time will be tight. Gotta keg while the kegging’s good!
My cold storage space is also tight, so I’ve decided to get the beers carbonated and conditioned using a more “traditional” keg priming technique. Not only does it cut down on my CO2 usage, but it also should help to eat up any residual oxygen from the transfer and help the beers stay a bit fresher. Now of course it would be ideal to do the full keg purge with CO2 and closed transfer thing. But as I said…I’m tight for time and not keen on always blowing through my CO2 supply. I also feel that these two beers should hold up pretty well (both are fairly high alcohol and one is quite tart); if it was a delicate lager, crystal malt heavy porter, or hoppy IPA, I would definitely do things differently.
In any case, here are the details on everything.
I brewed this beer on June 25, and fermented it at the ambient temperature–around 75° on up. I kegged the batch on 12 July 2017, with 2.75 oz. of corn sugar boiled in 1 cup of water. Around 5 gallons went into the keg. Final gravity was 1.003, down from 1.055. This works out to around 6.8% abv.
I brewed this beer on 27 June, fermenting it at around 66°. On the fourth day of fermentation, 1 July 2017, I added around 1L (~4.25 cups) of Vintner’s Harvest raspberry puree. After about a week, I moved it out of the fermentation chamber to finish out at ambient temperature, around 78°.
I kegged the beer on 14 July 2017. The flavor was nice and tart, although at this point the raspberry comes through more in the aroma than in the flavor. I will have to see if that changes when I chill it and serve it carbonated; there might be some minor adjustments required prior to the festival, if that’s the case.
Because I wanted to keep this beer for home use too, I split it between two mini-kegs. Three gallons went into one, with 1.82 ounces of corn sugar boiled in 1 cup water (targeting around 3 volumes of CO2). The remaining 2 gallons or so went into another keg, which I force carbonated to around 2.8 volumes.
Final gravity for this batch was 1.013, down from 1.044. That clocks in at 4.1% abv–a very nice session beer!
