we have some of the old Grolsch bottles with the metal flip top and porcelain caps that’s worth 5-8 bucks a piece …but realized no ones ever tried any and it seems they make different types of beer and some of it is very strong and wondered if it was worth importing some to try …
so id thought id ask some of the beer snobs… i mean drunkards 
…erm aficionados what they thought
They’re okay (not a beer I give a shit about, to be honest) , but the bottles are a bit sought after by home brewers because they don’t require capping. (Assuming you’re talking about the swing top caps.)
I used to take a 4-pack home with me from time to time. Definitely a decent beer, if not an outstanding one.
It’s been years since I had a Grolsch but if memory serves me well I’m gonna have to go with cat piss.
The green bottle it comes in does it no favours. If you can get it fresh and ‘unskunky’ then it is a good enough beer but it seems to get skunky more often than Heineken.
I used to like Grolsch back in the day. Provided it was unskunked and cold, it was a refreshing hot day beer- miles better than Heinekin, I thought.
But if the OP is asking if some old, full bottles of Grolsch that had been sitting around are still good, yeah, no… probably not, especially if they’ve been exposed to light, with that green bottle.
I love an ice cold grolsch. If offered. But I never find myself buying them. Let alone importing them.
If you like Grolsch, I’d concentrate on finding fresh beer more than I’d worry about trying to find Grolsch in particular. Since they import it from the Netherlands, it’s not going to ever be at its best here in the US, and it’s often skunked and not good by the time it reaches someone’s home fridge.
Stylistically, Grolsch is a pretty generic adjunct pilsner, although more hoppy and a tad heavier than the US mass-market pilsners. I’d actually say the closest, freshest options from craft brewers would be their Pilsner or Mexican lager offerings.
Are you sure Grolsch uses adjuncts? From what I’ve googled, it doesn’t seem they do.
I would have assumed it was an adjunct lager; it certainly tastes like one to me.
Some more googling points out that it used to be one around 2005-ish, but they’ve apparently phased that out.
Either way, it’s a pretty standard example of International Light Lager, in the same general category as Heineken, Carlsberg, Beck’s, Moretti, Peroni, Stella Artois, etc…
I like em. But I get them for the bottles (homebrewer). They are kinda skunky, but sometimes that’s a good thing.
Never actually bought any. But Princess Cruises served them and I had a mountain of free drinks, so ‘bought’ them there. Advantage: Can walk away with hand fulls, and re-cap for later drinking, and take the bottles home. My suitcase was nearly rejected on the way home from the last cruise.
