** A growler is simply a glass jug that carries 64 ounces of your favorite Nashoba Valley fresh Draft beers. You pay for the jug and fresh draft beer inside ($22.50 plus fill price) and you’re on your way. The best part is you can bring the Growler back in for refills ($7.00 for standard beers $9.00 for premiums, $12.00 Special Reserve). That is about a six pack of beer for $7.00 or just slightly more than a dollar a glass. Just note that you must always refrigerate growlers. Doing so will give them a shelf-life of 7-10 days, or around 2-3 days once opened.
