1977-1980

With Carlos Loyzaga handling the coaching chores by 1977, replacing Bobby Littaua, Tanduay entered the semifinals for the first time in the 1977 All-Filipino Conference and almost made it to the finals but lost to Mariwasa-Honda Panthers on their last assignment as the Panthers went on to play the Crispa Redmanizers for the championship. The season had a Tanduay player Jaime Taguines becoming the second recipient of the Rookie of the Year honors.

In 1978, Tanduay had their first breakthrough year. After a third and fourth place finishes in the first two conferences of the season, the third conference Invitational Championship allows the Esquires to simultaneously field their two imports. Gene Moore and David Payne led the team to score upset victories and enter the finals series against the Toyota Tamaraws. The Esquires lost to defending champion Toyota in four games. Tanduay again produced another Rookie of the Year awardee for the second straight season in Jaime Manansala.

1979-1984

The next six seasons would remain unfruitful and title-less campaign for the Tanduay ballclub despite being competitive and a darkhorse team in the early 1980s, signing some top amateur stars like Rey Lazaro, former San Beda Red Lions Frankie Lim and JB Yango. The team had a revamp of their lineup in 1984, giving up four of its veteran players, Roberto dela Rosa, Victor Sanchez, Alberto Gutierrez and Mike Bilbao to newcomer Beer Hausen.

1985–1987

Following the disbandment of the famed Crispa Redmanizers, the Tanduay Rhum Makers had a massive rebuilding, acquiring Crispa stars Abet Guidaben, Freddie Hubalde and Padim Israel, along with Willie Generalao from Gilbey's Gin. However, three weeks after the start of the 1985 PBA Reinforced Conference, Guidaben was traded in favor of Ramon Fernandez from Manila Beer. Tanduay's coach at that time, Orly Castelo, was also replaced by former Gilbey's Gin coach Arturo Valenzona.

Tanduay finally won the first of three PBA championships beginning in the 1986 First Conference, behind imports Rob Williams and Andre Mckoy. ^[2] After winning its first title, the team brought the championship trophy to the grave of their late owner, Manolo Elizalde, who died a year before. Tanduay won their second straight championship in the 1986 PBA All-Filipino Conference and their third title in the 1987 PBA Open Conference with best import David Thirdkill.

Disbandment

A business blackeye occurred in late 1987 when a couple of Tanduay drinkers died allegedly owing to the liquor. This caused a major backlash in terms of sales as revenues collapsed and put parent company Elizalde & Company Inc. near bankruptcy.

Pure Foods Corporation, then a subsidiary of Ayala Corporation, acquired Tanduay's PBA franchise. The franchise would play under the name Purefoods beginning the 1988 PBA season.

The Tanduay business enterprise was acquired by the Lucio Tan group of companies.

In the Philippine Basketball League (1997-1999)

In 1997, the Tanduay name resurfaced in the Philippine basketball scene at the Philippine Basketball League under the ownership of Lucio Tan group of companies and managed by son Lucio "Bong" K. Tan, Jr. Prior to using the name "Tanduay Gold Rhum Masters", this team was originally known as Stag Pale Pilseners from 1995-1996, with Marlou Aquino, Bal David and Jason Webb in the lineup. The Rhum Masters won several PBL crowns under coach Alfrancis Chua and players Eric Menk, Jomer Rubi, Chris Cantonjos and Mark Telan. It also held a PBL-record 18 straight wins in the 1998–1999 Yakult PBL Centennial Cup, but lost in five games to Doctor J Rubbing Alcohol, when the Centennial Rhum Masters blew a 2–0 lead in the best-of-five affair. After the team moved to the PBA, Asia Brewery retained the PBL franchise and was renamed Colt 45 with Renren Ritualo leading the squad. Colt 45 placed fourth in the 1999 PBL Challenge Cup before disbanding.

Return to the PBA (1999-2001)

In 1999, Tanduay made its return to the PBA. As part of the agreement, the league allowed six players from Tanduay's PBL lineup to be elevated. Tanduay also acquired Fil-American Earl Sonny Alvarado as the top pick. The records from the original Tanduay franchise (1975-1987) were retained for this franchise.

In its first season, Tanduay placed second to Shell in the 1999 PBA All-Filipino Conference but their second stint in the PBA were marred by several controversies such as the deportation of alleged "Fil-sham" (bogus Filipino) Alvarado which led to a forfeiture of several Tanduay games during the 2000 season. In the 2001 offseason, Tanduay made soundwaves in the PBA when they signed Danny Ildefonso of corporate rival San Miguel Beermen a whopping 16-year, 98 million peso offersheet. The league though, nullified the said deal since it was believed that the offersheet violated the team's salary cap.

Bong Tan also made a controversial comment calling the PBA, "a San Miguel league", a reference to a speculation that the PBA is favoring the then-San Miguel Corporation teams San Miguel and Barangay Ginebra. It was also said that Tanduay violated the PBA's salary cap many times by having their players sign a separate contract apart from the required PBA Uniform Player's Contract that made the players richer than any PBA team's bench players by a few hundred thousand pesos. This was already denied by the management.

Disbandment

Realizing its failure to win a championship despite a stellar line-up of Fil-American players and established veterans, Tanduay disbanded after the 2001 season, selling its PBA franchise to FedEx Express for a reported sum of PHP 60-75 million. A firesale ensued as the Rhum Masters traded their key players Eric Menk (to Barangay Ginebra Kings), Dondon Hontiveros (to the San Miguel Beermen) and Jeffrey Cariaso (to the Coca-Cola Tigers).
