Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States (“GAAP”) for complete consolidated financial statements. In the opinion of management, all adjustments (consisting only of normal recurring accruals, unless otherwise indicated) considered necessary for a fair presentation of the interim financial data have been included. Operating results for the three and nine months ended March 31, 2013 are not necessarily indicative of the results that may be expected for the fiscal year ending June 30, 2013. Events occurring subsequent to March 31, 2013 have been evaluated for potential recognition or disclosure in the unaudited consolidated financial statements for the three and nine months ended March 31, 2013. The accompanying unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2012, filed with the Securities and Exchange Commission (the “SEC”) on September 10, 2012.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company reviews its estimates on an ongoing basis using currently available information. Changes in facts and circumstances may result in revised estimates and actual results may differ from those estimates.
Fair Value Measurements	Fair Value Measurements Fair value is the price that would be received to sell an asset or paid to transfer a liability, in an orderly transaction between market participants. The Company maximizes the use of observable market inputs, minimizes the use of unobservable market inputs and discloses in the form of an outlined hierarchy the details of such fair value measurements. See Note 2 for additional information.
Coffee Brewing Equipment and Service	Coffee Brewing Equipment and Service The Company classifies certain expenses related to coffee brewing equipment provided to customers as cost of goods sold. These costs include the cost of equipment as well as the cost of servicing that equipment (including service employees' salaries, cost of transportation and the cost of supplies and parts) and are considered directly attributable to the generation of revenues from the Company's customers. Accordingly, such costs included in cost of goods sold in the accompanying unaudited consolidated financial statements for the three months ended March 31, 2013 and 2012 are $7.0 million and $6.7 million, respectively. Coffee brewing equipment costs included in cost of goods sold for each of the nine months ended March 31, 2013 and 2012 are $19.1 million. The Company capitalized coffee brewing equipment in the amounts of $7.1 million and $9.9 million in the nine months ended March 31, 2013 and 2012, respectively. Depreciation expense related to capitalized coffee brewing equipment reported as cost of goods sold was $3.2 million and $2.9 million in the three months ended March 31, 2013 and 2012, respectively. Depreciation expense related to capitalized coffee brewing equipment reported as cost of goods sold was $9.8 million and $8.7 million in the nine months ended March 31, 2013 and 2012, respectively.
Revenue Recognition	Revenue Recognition Most product sales are made “off-truck” to the Company's customers at their places of business by the Company's sales representatives. Revenue is recognized at the time the Company's sales representatives physically deliver products to customers and title passes or upon acceptance by the customer when shipped by third party delivery. The Company sells roast and ground coffee and tea to The J.M. Smucker Company ("J.M. Smucker") pursuant to a co-packing agreement. The Company recognizes revenue from the co-packing arrangement for the sale of tea on a net basis, net of direct costs of revenue, since the Company acts as an agent of J.M. Smucker in such transactions. As of March 31, 2013 and June 30, 2012, the Company had $0.3 million and $0.8 million, respectively, of receivables related to this arrangement, which are included in “Other receivables” in the consolidated balance sheets (see Note 4).
Earnings (Loss) Per Common Share	Earnings (Loss) Per Common Share Basic earnings (loss) per share ("EPS") represents net earnings attributable to common stockholders divided by the weighted average number of common shares outstanding for the period, excluding unallocated shares held by the Company's Employee Stock Ownership Plan ("ESOP"). Diluted EPS represents net earnings attributable to common stockholders divided by the weighted average number of common shares outstanding, inclusive of the dilutive impact of common equivalent shares outstanding during the period. However, nonvested restricted stock awards (referred to as participating securities) are excluded from the dilutive impact of common equivalent shares outstanding in accordance with authoritative guidance under the two-class method. The nonvested restricted stockholders are entitled to participate in dividends declared on common stock as if the shares were fully vested and hence are deemed to be participating securities. Under the two-class method, earnings (loss) attributable to nonvested restricted stockholders are excluded from net earnings (loss) attributable to common stockholders for purposes of calculating basic and diluted EPS. Computation of EPS for the three and nine months ended March 31, 2013 does not include the dilutive effect of 567,088 shares issuable under stock options since their inclusion would be anti-dilutive. Computation of EPS for the three and nine months ended March 31, 2012 does not include the dilutive effect of 662,810 shares issuable under stock options since their inclusion would be anti-dilutive. Accordingly, the unaudited consolidated financial statements present only basic net loss per common share for all periods presented (see Note 10).
Dividends Declared	Dividends Declared Although historically the Company has paid a dividend to stockholders, in light of the Company's current financial position, the Company's Board of Directors has omitted the payment of a quarterly dividend since the third quarter of fiscal 2011.

In addition to an annual test, indefinite-lived intangible assets must also be tested on an interim basis if events or circumstances indicate that the estimated fair value of such assets has decreased below their carrying value.

The estimated future cash flows are based upon, among other things, assumptions about expected future operating performance, and may differ from actual cash flows. If the sum of the projected undiscounted cash flows (excluding interest) is less than the carrying value of the assets, the assets will be written down to the estimated fair value in the period in which the determination is made.

The accompanying unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2012, filed with the Securities and Exchange Commission (the “SEC”) on September 10, 2012.

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company reviews its estimates on an ongoing basis using currently available information. Changes in facts and circumstances may result in revised estimates and actual results may differ from those estimates.

Fair Value Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability, in an orderly transaction between market participants. The Company maximizes the use of observable market inputs, minimizes the use of unobservable market inputs and discloses in the form of an outlined hierarchy the details of such fair value measurements. See Note 2 for additional information.

These costs include the cost of equipment as well as the cost of servicing that equipment (including service employees' salaries, cost of transportation and the cost of supplies and parts) and are considered directly attributable to the generation of revenues from the Company's customers. Accordingly, such costs included in cost of goods sold in the accompanying unaudited consolidated financial statements for the three months ended March 31, 2013 and 2012 are $7.0 million and $6.7 million, respectively. Coffee brewing equipment costs included in cost of goods sold for each of the nine months ended March 31, 2013 and 2012 are $19.1 million. The Company capitalized coffee brewing equipment in the amounts of $7.1 million and $9.9 million in the nine months ended March 31, 2013 and 2012, respectively.

Earnings (Loss) Per Common Share

Basic earnings (loss) per share ("EPS") represents net earnings attributable to common stockholders divided by the weighted average number of common shares outstanding for the period, excluding unallocated shares held by the Company's Employee Stock Ownership Plan ("ESOP"). Diluted EPS represents net earnings attributable to common stockholders divided by the weighted average number of common shares outstanding, inclusive of the dilutive impact of common equivalent shares outstanding during the period. However, nonvested restricted stock awards (referred to as participating securities) are excluded from the dilutive impact of common equivalent shares outstanding in accordance with authoritative guidance under the two-class method.

Impairment of Indefinite-lived Intangible Assets

The Company performs its annual indefinite-lived intangible assets impairment test as of June 30 of each fiscal year. Indefinite-lived intangible assets are not amortized but instead are reviewed for impairment annually by comparing their fair values to their carrying values.

In addition to an annual test, indefinite-lived intangible assets must also be tested on an interim basis if events or circumstances indicate that the estimated fair value of such assets has decreased below their carrying value. There were no such events or circumstances during the nine months ended March 31, 2013.

Long-lived Assets, Excluding Indefinite-lived Intangible Assets

The Company reviews the recoverability of its long-lived assets whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Long-lived assets evaluated for impairment are grouped with other assets to the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. The estimated future cash flows are based upon, among other things, assumptions about expected future operating performance, and may differ from actual cash flows.
