The sale forms part of a broader strategic overhaul unveiled by Greene King in March this year
Dozens of Greene King pubs have been put up for sale as the company reshapes its estate across the country.
Around 65 sites are being offered to potential buyers, although the move does not mean the pubs are set to close.
Greene King, the country's second-largest pub operator, placed the venues on the market today as part of a portfolio known as Project Portico.
Most of the pubs are "wet-led", meaning they focus mainly on selling drinks rather than food. Sapient Corporate Finance is advising Greene King on the sale.
Potential buyers can purchase all 65 pubs together, buy smaller groups of venues or make offers for individual sites.
Greene King has not revealed which pubs are included in the portfolio.
No closures have been linked to the sale, meaning the venues could continue trading under new ownership if they are sold.
A Greene King spokesperson said: "As part of our pub estate strategy announced earlier this year, we identified a number of pubs for potential sale in the medium term.
"As a result, we are reviewing each pub to determine the most appropriate route to market, which may involve an open sales process or a targeted off-market approach.
"In either case, prospective purchasers may seek to acquire individual or multiple sites."
The company said pubs with a similar operating profile have been grouped together when being offered to potential buyers.
Hospitality trade publication Propel was first to report details of the portfolio.
Greene King was founded in 1799 and currently runs around 2,500 pubs across the country. Of these, roughly 1,000 are operated under leased, tenanted or franchised agreements through its Pub Partners division.
The sale forms part of a broader strategic overhaul unveiled by Greene King in March this year.
At that time, the company flagged around 300 managed pubs as potentially better suited to alternative operating models.
Roughly half of those 300 sites are expected to transition into leased, tenanted or franchised venues within the group's existing Pub Partners network. The other 150 or so are being assessed for possible disposal over the medium term.
Today's Project Portico listing represents the most substantial tranche of that disposal programme to reach the open market.
The company has stressed that proceeds from any completed sales will be channelled back into strengthening its core pub estate rather than extracted from the business.
Greene King has already begun trimming its portfolio through smaller disposals this year.
In April, the company instructed Savills to market 13 freehold pubs and hotels with a combined total of 420 bedrooms, among them Ye Olde Talbot in Worcester, the Cromwell Lodge Hotel in Banbury and the Bear Hotel in Havant.
A further ten freehold managed pubs were brought to market via AG&G the following month.
Eight of those carried a collective asking price of roughly £9.4million, with offers invited on the remaining two. Six were still trading at the point of sale, while four had already ceased operations.
The company's most recent financial results painted a positive picture, with revenue rising 3.6 per cent to £2.539billion and adjusted operating profit climbing 9.8 per cent to £217.4million.
