The Current Big Bertha Lineup: 2023 Model

The Big Bertha 23 lineup is Callaway’s answer to a clear question: How do you build a club that truly helps recreational golfers? The 2023 model series includes Drivers, Fairwaywoods, Hybrids, and Irons—as well as the women’s line, Big Bertha REVA 23.

Big Bertha 23 Driver

The Callaway Big Bertha 23 Driver is designed to reduce Slice and maximize forgiveness. Callaway’s R&D team has positioned the center of gravity (CG) extremely low and close to the heel—this promotes a Draw bias and helps minimize typical Slice issues.

• Target audience: Golfers with a handicap of 18–54 who struggle with consistency
• Price: starting at €299.99

Big Bertha 23 Fairwaywood and Hybrid

The Callaway Big Bertha 23 Fairwaywood follows the same philosophy: low CG, plenty of forgiveness, and easy ball launch. Ideal for golfers who regularly struggle with their Fairwaywood. The Callaway Great Big Bertha Hybrid combines proven Big Bertha technology with modern Hybrid construction for easy launch and high, long-carrying shots.

Big Bertha REVA 23 Iron set (Women’s)

The Callaway Big Bertha REVA 23 iron set was developed specifically for women: optimized lofts, swing weights, and shaft lengths designed for a slower swing—for more distance with less effort.

What is the Big Bertha REVA—and who is it designed for?

The Big Bertha REVA is Callaway’s women’s line under the Big Bertha banner. It was first introduced in 2020 alongside the B-21 and has been continuously refined ever since. The R&D team designed these clubs specifically for female golfers after significant research: adjusted lofts, shorter shaft lengths, lower swing weights, and particularly responsive clubfaces.

The REVA line is aimed at beginner and intermediate female golfers with medium to higher handicaps who want distance and control without having to exert excessive force.

Technology at a Glance: What's Inside the Big Bertha Clubs?

Over the decades, Callaway has consistently equipped the Big Bertha family with its latest core technologies. Here are the most important ones:

A.I.-Optimized Flash Face

Since the B-21 generation (2020), Callaway has been using an AI-developed Flash Face Cup architecture in its Big Bertha irons. The face is individually calculated for each club number to maximize ball speed and spin consistency across the entire hitting area—even on off-center hits. First introduced in 2017 in the Epic line, Jailbreak was also incorporated into Big Bertha hybrids starting in 2018. Two internal rods stiffen the clubhead, so that more energy is transferred directly to the face upon impact—resulting in measurably higher ball speed.

Suspended Energy Core (2018 Irons)

The 2018 Big Bertha irons introduced a design that was unique at the time: a metal injection-molded (MIM’d) tungsten weight is suspended within urethane microspheres. The suspended weight allows for a lower center of gravity (CG) while also improving sound and feel. Combined with a thinner 360 Face Cup, this design delivers higher launch angles and increased ball speed.

Visible Tungsten Energy Core – VTEC (2020 B-21 Irons)

The successor to the Suspended Energy Core: The tungsten weight is visibly embedded in the sole of the VTEC. It lowers the CG even further, promoting an even easier launch—especially valuable for golfers with slower swing speeds. A flexible edge around the entire face flexes and releases upon impact—this increases ball speed even across the entire face outside the sweet spot. Thanks to the Suspended/VTEC Energy Core, Callaway was able to design the face progressively thinner than in previous models. The shorter, lighter OptiFit hosel system —introduced in 2018—saves weight that is strategically utilized to achieve an optimal CG position—for easy takeoff and high, long-carrying shots.

The Development Timeline: 2013 to 2023

What is the difference between Big Bertha and Big Bertha OS Irons?

OS stands for Oversize —and describes an even larger, more forgiving clubhead shape than the standard Big Bertha Irons. The OS irons were introduced in 2016 and were explicitly designed for golfers in the Super Game Improvement category—that is, high-handicap players and beginners who struggle primarily with consistent ball contact.

The evolution of this line—featuring new technologies like VTEC and AI-optimized clubface—spanned the 2018 and 2020 generations to reach the current lineup.
