Maxxx elevates the BBQ briquet to a bigger, better fuel. Maxxx briquets contain no fillers, chemicals, or toxic mystery ingredients that produce bitter smoke and mountains of ash. So, what is in them? The same incredibly dense hardwood Jealous Devil uses to make their lump charcoal, plus a pinch of plant-derived starch (that is it, yes, really). It is compressed into the biggest pillow briq on the market for the longest burn time on the market, and put in a cool waterproof resealable package.
