The most common feedback we have gotten over the last 14 years is "you grow the BEST carrots". We don't know why it is, but we agree. Our sweet storage carrots got frosted HARD before we dug them, so they're even sweeter than our summer carrots. We have eaten a properly stored carrot harvested TEN MONTHS prior and it was still crunchy and sweet.
Store in a humid, cold place (right in the bags we sell them in, in your fridge, is best). Do not let freeze.
