As many of you are aware, we took quite a while before we started doing growler fills. This was for a number of reasons but first and foremost among these is the fact that since our beer is only available in our tasting room, we wanted to make sure that any beer "to go" was as close to as good as it is right off the taps. I found some faucet adapters called the "Bowie Bottler" and rigged up filling wands similar to the principal of bottle fillers where the beer is filled from the bottom under presssure.
We have now been using these for around a month and I happen to have a couple of bottles at home that were filled four weeks ago to the day. Just as carbonated as it was when it was bottled with no discernable off flavors. So far so good. I will try the other bottle in another month or two and let you know. Here is an image of the Extra Pale Ale for your enjoyment (actually for mine :-D).
On another note, I don't think we mention this very often but since our beer is not pastuerized and not filtered, it should ALWAYS be kept cold and will not hold up to shipping well either.
