Storring Beer to Bottle Later

[nicklawmusic]

I am currently setting up a brewery in the UK. At the moment, I'm cuckoo brewing of sorts on their pilot kit. It only does 18 gallons, so I'm packing around 60-80L per batch in bottles. I work one day a week (in theory!) at the brewery so I'm trying to brew as much as possible in order to make stock. I guess it's a glorified version of homebrewing in one sense.

Here's my predicament...

I'd like to brew for three weeks and bottle batches on the fourth and fifth. This means i need to rack beer out of the fermentors into something. My plan thus far has been to store it in casks and use those as makeshift conditioning vessels. I'm good to fill one ferkin full but have found that I dont have enough beer to fill a second ferkin full, meaning there's air in the cask (in this instance it has 30L of beer in it).

I decided to put a tiny bit of priming sugar into the cask and an airlock so there would be some CO2 in there blanketing the beer.

I'm wondering, on such a small scale (or even on a bigger small scale for those bottle condition relatively small batches), what's the best way of storing beer so I can do a mass bottling session, rather than having to bottle every 2 weeks?

I hope that made sense!

Thanks,
Nick
