  A fermented beverage is described together with a method for its production from one or more component of a Cannabis plant. The beverage comprises carbohydrates derived from hydrolysis of cellulose and/or hemicellulose from Cannabis , as a fermentation substrate. The beverage may contain alcohol or may be non-alcoholic. Active phytocannabinoid compounds may be present, preferably in the non-alcoholic beverages. The method includes the steps of (a) obtaining a cellulose-rich pulp from the one or more components of the Cannabis plant, from which lignin and/or hemicellulose has been released (through any number of multiple prehydrolysis steps); (b) degrading the cellulose-rich pulp into carbohydrates (saccharification step) with enzymatic hydrolysis by one or more cellulose-degrading and/or hemicellulose-degrading enzymes, and/or with acid hydrolysis to form carbohydrates; (c) preparing a wort from the carbohydrates with (or if desired without) sufficient yeast nutritional requirements and flavoring from portions of the Cannabis plant; and (d) fermenting the wort to form the fermented beverage. (e) Optionally performing steps to finish the beer including but not limited to aging, alcohol removal, formulation and flavoring by addition of phytocannabinoids and/or terpenes, xylooligimers, and/or Cannabis extracts and/or Cannabis oils with or without accelerants (to accelerate the onset of the bioactive effect) and/or deccelerants (to shorten the duration of the bioactive effect) as desired. The optional removal of alcohol may be conducted by reverse osmosis or other process. Phytocannabinoids or flavorings may be introduced as desired.
