Amstel Gold., which is still knocking around, is a sort of strong Pils. Or something like that. Stylistically, it's all a bit vague. I think Amstel introduced it in the 1950s. If I could be arsed to look through their sales records, I could pin down the precise date. But I can't. Be arsed, that is. It's a bit of an oddity in the Dutch beer market. There isn't a similar product I can think of from any of their rivals.
The thought clearly crossed Heineken's mind. Enough to bash out a trial brew. It doesn't seem to have gone any further. Though I'd need to trawl the main brewery records to be sure of that.
How similar were the two beers? Well, I just so happen to have Amstel records for the same year. I've even a real version brewed almost on the same exact day. As you can see below.
The basic spec look pretty similar. Heineken's is a bit lower in OG, but the hopping rates are almost the same. Which doesn't mean they would have tasted the same. Just that they would have been generally similar in character.
