Yes. We can ship namazake, however it is at the customer's discretion. Namazake is pretty sturdy, and at the right temperature, can make it to its destination safe and sound. Some namazake actually holds up better than others. Ask someone on the True Sake team for more info. It's usually best to avoid shipping namazake during the summer, but some customers roll the dice, and their namazake makes it to them without any issues. We will usually contact customers to get their approval to ship namazake unless they've instructed us otherwise.
We do not use ice packs, as a melting ice pack does compromise the integrity of a cardbox box, which leads to damaged packages. At the end of the day, ice packs actually do more harm than good. We also do not have the facility to house dry ice.
Namazake is an unpasteurized sake. Traditional sake is usually pasteurized twice. Namazake is typically pasteurized zero times, however there are variations of namazake that are pasteurized once.
