I have found that the price of most barrels doesnt make it worth wile when the cornys are £50 or less from norm on ebay
and they are good for this time of year if you keep them in the shed , and you can allways fill a bottle from the corny too so you get best of both worlds.
they are 19ltr so you got about 1Ltr to bottle up for a 20ltr brew more for bigger brews
but they need company more is better with theese
