The original Grand Cru model, witch this model is based on, features a top bolster (the metal part where the screw enters the handle). The main reason the Grand Cru was introduced was to offer a more durable wine opener. Although the new Chateau Laguiole 2020 Classic model's construction is as strong as the Grand Cru, this series continues to be offered.
What is a Forged Bee? You can recognize a forged bee when you look just below it, where it meets the decorated spring. If you do not see any gaps, it's a good sign that the bee and spring were forged from the same piece of metal. You can also recognize a soldered bee by noticing a straight gap/ridge where the bee meets the spring.
At 18000 ml (18 liters/4.75 gallons), the "Melchior" is the largest production bottle size available in the market today. To put it in perspective, it contains the equivalent of 24 standard bottles of wine, and you could fill 144 glass with just one bottle.
