I ran adventure tours on the Cape York Penninsular in north Queensland
for over six years during that time we always froze our beer
. We had a pretty decent fridge for the food
and would pre freeze cartons of beer
and load them into an esky(cooler to US citizens and Chilly bin to the Kiwi's). This was so the food
temp wasnt comprimised with 10 very thirsty dirt bike riders constantly opening the fridge to inhale beers at the end of the day. As the tour went on we would tend to eat the more perishable foods first (ckicken ,fish) and then move on to the cryovacked (vacume sealed) beef. As this happened we would load beer into the new space in the fridge at the start of the day when a full days running of the truck would allow the beer temp to be pulled down without sucking the batteries dry and load them into the esky at the end of the day.
We would fill the esky with frozen beer and leave just enough room for what we estimated we would drink the first day, and load in verry cold but unfrozen beer in that space. drink that beer that night next day chill some more in the new space left in the fridge that night load into esky by about the trird or fourth day all the beer in the esky was defrosted but still very very cold at which point we would start to get some ice and or load up the now pretty empty fridge.
The trick with freezing the beer is to (if youve got the room) load it into the freezer
carton and all, or at least load a heap in at once and group it together so that it takes longer to freeze, in six years and an estimated 2160 cartons of beer we never had a complaint and burst half a dozen beers.
As a reformed full mash home brewer and beer nut i can vouch that as long as the beer is allowed to thaw properly the flavour is not affected.
Oh and if your stacking lots of beer and the rides a bit rough you can loose cans from rubbing very quickly keep them upright and tightly packed and every second layer turn upside down, this stops the base edge of the can punching the pull tab of the can below.
