Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. Organization: Ceres Classic L.P. (the “Partnership”) is a Delaware limited partnership organized in 1998 to engage primarily in the speculative trading of futures contracts, options on futures and forward contracts, forward contracts on physical commodities and other commodity interests, including, but not limited to, foreign currencies, financial instruments, metals, energy and agricultural products (collectively, “Futures Interests”) (refer to Note 4, “Financial Instruments”). The General Partner (as defined below) may also determine to invest up to all of the Partnership’s assets in United States (“U.S.”) Treasury bills and/or money market mutual funds, including money market mutual funds managed by Morgan Stanley or its affiliates. Ceres Managed Futures LLC, a Delaware limited liability company, acts as the general partner (“Ceres” or the “General Partner”) and commodity pool operator of the Partnership. The General Partner is a wholly-owned subsidiary of Morgan Stanley Domestic Holdings, Inc. (“MSD Holdings”). MSD Holdings is ultimately owned by Morgan Stanley. Morgan Stanley is a publicly held company whose shares are listed on the New York Stock Exchange. Morgan Stanley is engaged in various financial services and other businesses. Morgan Stanley Smith Barney LLC is doing business as Morgan Stanley Wealth Management (“Morgan Stanley Wealth Management”). This entity currently acts as the placement agent for the Partnership. Morgan Stanley Wealth Management is a principal subsidiary of MSD Holdings. As of June 30, 2021, all trading decisions were made for the Partnership by Graham Capital Management, L.P.

Investments, All Other Investments [Abstract]
Financial Instruments	4. Financial Instruments: The Partnership trades Futures Interests. Futures and forwards represent contracts for delayed delivery of an instrument at a specified date and price. The fair value of an exchange-traded contract is based on the settlement price quoted by the exchange on the day with respect to which fair value is being determined. If an exchange-traded contract could not have been liquidated on such day due to the operation of daily limits or other rules of the exchange, the settlement price will be equal to the settlement price on the first subsequent day on which the contract could be liquidated. The General Partner estimates that, at any given time, approximately 32.0% to 37.7% of the Partnership’s contracts are traded over-the-counter. In general, the risks associated with non-exchange-traded non-exchange-traded The Partnership also has credit risk because MS&Co. acts as the commodity futures broker, or the counterparty, with respect to most of the Partnership’s assets. Exchange-traded futures and exchange-traded forward contracts are fair valued on a daily basis, with variations in value settled on a daily basis. With respect to the Partnership’s non-exchange-traded non-exchange-traded non-exchange-traded The General Partner monitors and attempts to mitigate the Partnership’s risk exposure on a daily basis through financial, credit and risk management monitoring systems, and accordingly, believes that it has effective procedures for evaluating and limiting the credit and market risks to which the Partnership may be subject. These monitoring systems generally allow the General Partner to statistically analyze actual trading results with risk adjusted performance indicators and correlation statistics. In addition, online monitoring systems provide account analysis of U.S. Treasury bills, futures, forward and option contracts by sector, margin requirements, gain and loss transactions and collateral positions. The Futures Interests traded, and the U.S. Treasury bills held, by the Partnership involve varying degrees of related market risk. Market risk is often dependent upon changes in the level or volatility of interest rates, exchange rates, and prices of financial instruments and commodities, factors that result in frequent changes in the fair value of the Partnership’s open positions, and consequently, in its earnings, whether realized or unrealized, and cash flow. Gains and losses on open positions of exchange-traded futures and exchange-traded forward contracts are settled daily through variation margin. Gains and losses on non-exchange-traded In the ordinary course of business, the Partnership enters into contracts and agreements that contain various representations and warranties and which provide general indemnifications. The Partnership’s maximum exposure under these arrangements cannot be determined, as this could include future claims that have not yet been made against the Partnership. The General Partner considers the risk of any future obligation relating to these indemnifications to be remote. Since its discovery in December 2019, a new strain of coronavirus, which causes the viral disease known as COVID-19, The outbreak of the novel coronavirus in many countries is having and will likely continue to have an adverse impact on global commercial activity, which has contributed to significant volatility in financial markets. The global impact of the outbreak has been rapidly evolving, and as cases of the virus have been identified in additional countries, many countries have reacted by instituting quarantines and restrictions on travel. These actions are creating disruption in supply chains, and adversely impacting a number of industries, including but not limited to transportation, hospitality, and entertainment. The impact of COVID-19 The rapid development of this situation precludes any prediction as to the ultimate adverse impact of the novel coronavirus. Nevertheless, the novel coronavirus presents material uncertainty and risk with respect to the Partnership’s investments and operations.

Investment In The Trading Company	7. Investment in the Trading Company: On January 1, 2021, the assets allocated to WCM for trading were invested in CMF Winton, a limited partnership organized under the partnership laws of the State of New York. CMF Winton permits accounts managed by WCM using the Winton Futures Program, a proprietary, systematic trading system, to invest together in one trading vehicle. The General Partner is also the general partner of CMF Winton. Individual and pooled accounts currently managed by WCM, including the Partnership, are permitted to be limited partners of CMF Winton. The General Partner and WCM believe that trading through this structure promotes efficiency and economy in the trading process. The General Partner and WCM have agreed that WCM will trade the Partnership’s assets allocated to WCM at a level that is up to 1.5 times the amount of assets allocated, provided that the General Partner may instruct WCM to change such level in accordance with the investment management agreement from time to time. The General Partner is not aware of any material changes to the trading program discussed above during the fiscal quarter ended June 30, 2021. The Partnership’s/Trading Company’s trading of futures, forward, swap, and option contracts, if applicable, on commodities is done primarily on U.S. and foreign commodity exchanges. The Partnership/Trading Company engage in such trading through commodity brokerage accounts maintained with MS&Co. Generally, a limited partner in the Trading Company may withdraw all or part of its capital contribution and undistributed profits, if any, from the Trading Company as of the end of any month (the “Redemption Date”) after a request has been made to the Trading Manager at least three days in advance of the Redemption Date. Such withdrawals are classified as a liability when the limited partner elects to redeem and informs the Trading Company. However, a limited partner may request a withdrawal as of the end of any day if such request is received by the Trading Manager at least three days in advance of the proposed withdrawal date. Management fees, General Partner fees, ongoing selling fees and incentive fees are charged at the Partnership level. All clearing fees paid to MS&Co. are borne directly by the Partnership for its direct trading. In addition, clearing fees are borne by the Trading Company and allocated to the Trading Company’s limited partners, including the Partnership. Professional fees are borne by the Trading Company and allocated to the Partnership, and also charged directly at the Partnership level. At June 30, 2021, the Partnership owned 100% of CMF Winton. It is the Partnership’s intention to continue to invest in the Trading Company. The performance of the Partnership is directly affected by the performance of the Trading Company. Expenses to investors as a result of investment in the Trading Company are approximately the same as they would be if the Partnership traded directly and redemption rights are not affected.
