As the pinnacle of Callaway’s 2014 line of drivers, the Big Bertha Alpha has garnered a huge amount of interest since being introduced a month ago. With the reintroduction of the Big Bertha name, Callaway is claiming that the Alpha represents the most technologically advanced driver they’ve ever produced.

Big Bertha Alpha

Where do we begin? Big Bertha Alpha is the first driver to enable independent adjustments of four significant performance characteristics, optimizing trajectory, control and distance for individual golfers. The four independent variables are loft, lie, CG (draw) bias, and most innovatively (and for the first time ever), CG height.

The Big Bertha Alpha represents the most advanced engineering Callaway has ever commercialized in a driver, and the Company’s most flexible and comprehensive fitting platform ever.

The goal of driver design at Callaway is to individualize performance optimization for every golfer, giving them the best chance to optimize driving distance. And the innovative Big Bertha Alpha Driver is the ultimate representation of this philosophy.

Key Technology

Gravity Core


“For the first time ever, the Big Bertha Alpha’s Gravity Core lets golfers adjust spin independently of launch angle, a natural (and dramatic) extension to loft adjustability in a driver head. This adjustability breaks the fixed relationship between launch angle and backspin for the first time, providing a major asset in the fitting process to find optimal distance for a wide range of players’ abilities.”

It’s hard to imagine, but this tiny piece of metal is really the centerpiece of the Alpha’s multifaceted approach to adjustability. Adjustments are simple and use the same torque wrench that most golfers are already familiar with. Simply unscrew the cover and place the Gravity Core inside with the heavy tip up or down. The reason that such a small change is so groundbreaking is that it allows golfers to alter spin rates without affecting launch angles.

Many will ask why that it is important and the answer may be somewhat complicated for many casual golfers. Still, it’s something that can be explained with a little effort. In a general sense, loft has always been intrinsically tied to backspin. With a driver, too little or too much backspin can affect how far you hit the ball.

The easiest way to see how loft and spin work together is to think about it in the broadest and most general way possible – your driver versus your 9 iron. The driver has around 10° of loft and the 9 iron has around 40-42°. The driver should produce spin rates in the 2,000’s and the 9 iron may go all the way up into the 8,000’s. Again, this is much generalized, but it shows the correlation.

With driver fitting, the key is often to find that sweet spot where launch and spin combine to produce the longest carrying ball that still lands at the right angle to provide the maximum possible rollout for each individual swing.

By altering the center of gravity inside the Alpha, the Gravity Core allows the player to tweak the spin rates without changing launch angle, so it disconnects those two things that have always been connected. If everything else is perfect (i.e. launch angle), but spin is just a little too high, the Gravity Core allows the user to adjust it exclusively.

Launch monitor testing by THP on both Trackman and Vector X showed changes in back spin that ranged anywhere from 250 to 450rpms (depending on the player) without significant changes in launch angle.  For some players, this resulted in substantial difference in ball flight and distance when used in concert with the other features the Alpha offers.

Advanced Adjustable Hosel

“Big Bertha enables golfers to independently adjust loft and lie angle to help translate the added ball speed into more distance. Golfers can chose from four different lofts (from -1 to +2) to optimize launch angle and backspin and two different lies, denoted by ‘D’ for Draw and ‘N’ for Neutral, to optimize the directional bias. Together, these provide eight unique combinations that help golfers optimize their distance and dispersion. Callaway’s proprietary hosel technology is also the only adjustable hosel to achieve changes in loft and/or lie without having to rotate the shaft (and graphics) on its axis between settings.”

CG Bias

“Big Bertha Alpha also enables golfers to make adjustments to CG bias, which helps influence the shot shape. Big Bertha Alpha has a screw port in the heel and toe of the body and comes with 4 interchangeable weights: 1g, 3g, 5g, and 7g. This gives golfers a ton of flexibility in controlling both the shot shape and overall head weight. See, we weren’t kidding when we told you this was the most comprehensive fitting platform ever.”

Forged Composite

‘A critical competitive advantage for Callaway, Big Bertha Alpha’s crown is made of this high strength, lightweight material, which allows Callaway to offer three forms of adjustability while maintaining a very playable D3 swing weight.’

Forged composite is a piece of Callaway technology that has been around for years now, but it is a very important element in the Alpha. Adjustable drivers typically have more components, and that means more weight, whether it’s in the hosel or in the Alpha’s case – the center. By reducing crown weight with the ultralight forged composite, the Alpha avoids becoming an unwieldy, heavy driver even though it offers the most robust amount of adjustability seen in a driver to date.


The Alpha presents a contrasting look that blends some modern qualities suited for advanced technology with the clean look that many better players demand at address.

The sole’s high polish is almost mirror-like, with three red lines that serve to immediately draw the eyes to the Gravity Core’s port. Surrounding this is a metal-flake paint job that fades from deep blue to almost black.

Turning the club over reveals the crown, which is a very traditional pear shape devoid of any markings. The face is on the deeper side, though nothing out of this world, and the metal finish contrasts nicely with the dark crown.

Callaway chose the Mitsubishi Rayon Fubuki Zeta Tour shaft as the stock pairing with the Alpha and gripped it with a navy/white Golf Pride New Decade Mulitcompound Whiteout. The Zeta Tour is a tip-stiff shaft that should offer lower spin, along with a higher balance point that is becoming increasingly popular with both amateurs and professionals.


The Big Bertha Alpha was tested on the driving range using a variety of launch monitors. In addition, during a recent event called TheGrandaddy, eight members of the THP Forum were fit by Callaway using the Alpha at the Ely Callaway Performance Center in Carlsbad, CA.

What became apparent as time went on was that the Alpha was many drivers for many different swings, which makes it rather difficult to classify it inside normal narrow boundaries. Changes to the Gravity Core, perimeter weights, hosel settings, or the shaft gave distinct, and at times, dramatic changes to launch conditions and distance.

In general, the Alpha was a lower spin driver with moderate forgiveness, which will appeal to the better player, but even that is almost too narrow of a description, as THP observed a number of different skill levels and swing speeds that found success with it. Still, this driver is probably most suited for the advanced player that is looking to get his launch conditions perfect. The key theme was optimization through fitting and THP suggests that consumers utilize a fitter if considering a purchase. With so many potential configurations available, it would border on ridiculous to not have a trained eye with a launch monitor assisting.

In terms of forgiveness, the Alpha proved to be kinder to misses up and down the face, though lateral misses weren’t punished nearly as much when it came to ball speed and dispersion as what has been seen with another company’s low-spin driver. Interestingly, the Gravity Core not only produced changes to spin rates, it also allowed the user to match the center of gravity with where he normally strikes the ball on the driver face. For example, a number of players that typically missed higher on the face were able to produce better results with the Gravity Core inserted heavy side up (essentially moving the sweet spot higher on the face).

As noted earlier, most testers saw between 300 and 400 rpm’s difference in backspin through adjustments to the gravity core. One player reduced spin 600rpm compared to his TaylorMade R1, another driver featuring advanced adjustability. Through fitting he gained over 10 yards of carry distance, while decreasing dispersion by 12 yards. Another player was able to adjust the Gravity Core to react better to his normal ‘high face’ contact, with the end result being, higher launch, lower spin, and a gain of 15 yards carry distance over the Big Bertha, even with 3mph less ball speed.

Final Thoughts

As previously stated, ranking the Big Bertha Alpha on the typical linear scale so often seen in golf equipment reviews is virtually impossible. It offers a range of adjustments that was previously not available, and as such, can become a very different driver very quickly. That alone is its greatest achievement and makes it stand out among its many competitors. At its core, the Alpha is probably best suited for the advanced player, as it is among the lesser forgiving models in the 2014 Callaway line, but as noted, that too can be adjusted for the right player. At $499, it should be a crime to purchase the Alpha without a proper fitting. With all that potential, it just makes no sense to skip such an integral part of getting the most of out the driver.

  • Great write-up, Hawk. One of the most thorough and informative reviews I’ve read here.

  • Yes Sir! Great review Hawk! You hammered it buddy! Price point is a little high, but the technology and advancements out on this driver is amazing! The capability to tweak different bLl flight characteristics independently is innovation at its finest!

  • It’s beautiful and has all the bells and whistles however it may be a bit much for the average hacker. It sounds like the alpha driver would be more suited for the better player overall. You never know until you try it but I would be cautious to spend a bunch of money on something that may be over my skill level. Callaway has too many options to suit all players .

  • It’s exciting to see this driver advance the state of the art in driver design. To see the impact the gravity core has on performance, it just makes you wonder what they’ll do next, but in the meantime, this seems like a very useful tool in the right hands, and with so many fitting options, there are probably many hands that qualify. Thanks for the review.

  • Great review!
    I think this is the most excited I have been for a new driver in quite some time. The Gravity Core is finally a tech development that will change things for the golfer in a very real way. Anyone who’s ever been through a fitting has been there; the launch angle is great but the spin is just a tad too high. Problem solved thanks to Callaway.

  • The gravity core seems like such a huge leap in driver technology, and it sounds like it flat our works. I can’t wait to give this a swing in 2014. Callaway innovation in certainly changing the landscape!

  • Great review Hawk! Very thorough. The gravity core truly seems revolutionary.

  • #BOOM!

  • Excellent review. A club filled with technology that excites me. Wealth of information that you’ve passed on here. Well done!

  • Great review Ryan. I know many who spent time with it at the Grandaddy not only loved it, but were surprised in which settings worked for them. This is one that I think you ABSOLUTELY have to get on a launch monitor before buying, because what you think you may need in terms of placement of CG may not actually be what you need.

  • Incredibly informative Hawk. I truly enjoyed the read, and cannot wait to get my hands on one. Thanks for giving me something to look forward to on this cold Monday in January.

  • Great write-up Hawk. This is definitely on my “must hit” list for 2014. I had the old Biggest Big Bertha and would love to compare the old vs new tech

  • Excellent review Hawk, definitely not an off the rack purchase. Appreciate the thoroughness of your overview.

  • Great information here Hawk. I’m interested to see how many ‘weekend’ golfers get fit into the Alpha. Seems like if you take the time and truly understand the adjustment possibilites, this can be a game changer for many.

  • Interesting review Hawk. Just do much going on with this driver via technology and what we can now do with it on our own. To me, I get the feeling that maybe the main issue you and others might have had with it was in the forgiveness factor. I want to hit this very badly but will pay close attention to this as well. I think my Optiforce is very forgiving, esp. in other drivers I’ve used in the past, so will be curious how it stacks up. Thanks for the review!

  • Great read here, well done Ryan.Everything I wanted to know and a whole lot more. I hope the chance to swing this comes my way eventually, though with this technology being as new as it is, I really wonder what future adjustments will be brought to light!

  • Awesome review Ryan

  • Great write up here Ryan! I’m still astounded what they can do with adjusting the spin rates. So much tech in this and I know that I’ll never understand it all but I’m excited to see how this transforms the driver as we know it.

  • The technology in this driver is nothing I’ve ever seen. Adjusting spin rates independent of loft is quite the concept and I’d love to give this a swing and see it for myself! Wonderful review, Ryan!

  • Nice club. Sounds like the regular Big Bertha is more for me. I still want to smack some balls with this beauty!

  • Nice review Ryan, very thorough and well written

  • Nice review! I’ve been intrigued by this club since it was first announced. The technology is really intriguing, especially for club nerds like me. Beyond that, the re-introduction of the “Big Bertha” line has so much nostalgic value that I’m really considering giving this a look this season.

  • Great review Ryan! Extremely informative and the details behind the Gravity Core are just plan exciting!

  • Great review, thanks! I love it that Callaway is bringing back the Bertha name. I remember when the Berthas came out years ago and how nuts everyone was for them. It really changed the game in terms of the size of driver heads.

  • While you provided some good information, this “review” seems to be based solely on the experiences of others. You say it was tested on a driving range using multiple LM’s, yet I don’t see much in the way of feel, misses, tendencies, and so forth. Again, not a personal attack, but I feel like I got all of this same information from the Callaway website.

  • @Hookiller

    Always appreciate the feedback and offense taken.

    Took a bit of a different approach with this one after getting a rare chance to observe different players getting fit for the driver. Wanted to exhibit a broader variety of outcomes rather than just what one person (I) saw. In addition, was trying to make the technology easier to understand.

    Personally saw around 300rpm difference with gravity core change, but since my misses are generally lateral across the face, the Big Bertha proved to be a better match.

  • @Ryan Hawk

    I can appreciate that. Haha don’t be offended, it was not meant in that way at all. Thank you for the follow up though, and hey a little constructive criticism never hurts. I know doing reviews is not always an easy task, not to mention a very subjective one.

  • Sorry, that was a typo. Meant to say no offense taken. Thanks for reading!

  • Great write up. Looking forward to hitting one of these, and the new Big Bertha to see which one fits me the best.

  • I plan to get up to PGA SS sometime soon and try out a few 2014 drivers, this one is high on my list.

  • Got a shot of this driver today as my g20 getting reshafted, all I can say is spin rate down greatly! I rarely get any roll out on drives and as a 1 handicap get frustrated into a wind, but with this club it made no difference into headwind, didn’t quite like feel from face , felt harsh but couldn’t argue with results, but as article says, would have to spend a lot of time getting fitted properly with this club , and at
    £400 is an expensive purchase!

  • I know a lot of people winced at least slightly at the price of this club.
    But now that the 2015 drivers are out, you can pick up a slightly used BBAlpha for around $200. I just bought one for slightly less than $200 at the GolfMart in San Rafael, CA. If you happen to live near, ask for Nick. He used to own his own golf shaft shop and knows his stiff (and spent a half afternoon fitting me, and trying out different club options before we settle on the BB Alpha.
