I had one on draught that was horrifying. It reminded of someone's first homebrew batch. Not their first batch, but the first batch where they tried to "get creative" with a recipe. God awful.
In all honesty, none of the Sam Adams beers have ever been very good. I've never, ever, purchased the same product of theirs twice. Some are okay, some are meh and some are just craptacular.
Back on the subject of trader joes, avoid at all costs the Twin Screw Double IPA. Pure ****. Nothing double or IPA about it. Just junk. I wrote to their customer service since it's a private label thing I think and told them the beer tasted like a tampon soaked in stale beer. And that it was a fitting name, Twin Screw, since you're screwed when you buy it and screwed again when you drink it. They never wrote back.
