Yes you can, you can find them here. These gift vouchers can be purchased either for yourself or for a gift or for someone else by entering their email address when prompted. The voucher code will then be automatically sent to the recipient chosen. This email will include the voucher code and redemption options, but will not include billing details, which will be sent to the purchaser separately.
You can also now buy gift cards to use in our bars! More info just here: brewdog.com/gift-card
