Is it possible to download an entire WordPress site to use offline?

Hello all,

I’m currently building out a cocktail database using WordPress to manage content. Each recipe is tagged with ingredients and various other information to make searching easy for our salespeople. What I would like to do is load the entire database onto a USB stick for each salesperson to take with them to accounts where there is no internet access so that they can share information with clients. Is this possible? OS usage for our salespeople is split about 50/50 between Windows and OS X.

Thanks in advance for all of your help!
