Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The consolidated financial statements include the accounts of National Beverage Corp. and its subsidiaries. Significant intercompany transactions and accounts have been eliminated. The consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and rules and regulations of the Securities and Exchange Commission for interim financial reporting. Accordingly, they do not include all information and notes presented in the annual consolidated financial statements. The consolidated financial statements should be read in conjunction with the annual consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the fiscal year ended May 2, 2015. The accounting policies used in these interim consolidated financial statements are consistent with those used in the annual consolidated financial statements. The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. In our opinion, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Results for the interim periods presented are not necessarily indicative of results which might be expected for the entire fiscal year.
Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments We use derivative financial instruments to partially mitigate our exposure to changes in raw material costs. All derivative financial instruments are recorded at fair value in our Consolidated Balance Sheets. The estimated fair value of derivative financial instruments is calculated based on market rates to settle the instruments. We do not use derivative financial instruments for trading or speculative purposes. Credit risk related to derivative financial instruments is managed by requiring high credit standards for counterparties and frequent cash settlements. See Note 5.
Earnings Per Share, Policy [Policy Text Block]	Earnings Per Common Share Basic earnings per common share is computed by dividing earnings available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share is calculated in a similar manner, but includes the dilutive effect of stock options.
Inventory, Policy [Policy Text Block]	Inventories Inventories are stated at the lower of first-in, first-out cost or market. Inventories at August 1, 2015 are comprised of finished goods of $27.4 million and raw materials of $19.2 million. Inventories at May 2, 2015 are comprised of finished goods of $24.9 million and raw materials of $18 million.

Disclosure of accounting policy for major classes of inventories, bases of stating inventories (for example, lower of cost or market), methods by which amounts are added and removed from inventory classes (for example, FIFO, LIFO, or average cost), loss recognition on impairment of inventories, and situations in which inventories are stated above cost. If inventory is carried at cost, this disclosure includes the nature of the cost elements included in inventory.
