Bought a bag of malt yesterday at the local homebrew store, and when I opened it today I noticed dark gray to blackish insects in there. I had some unmalted wheat in there with the malts. The store milled the grains for me.

Not sure if I bought them with the malt or if they got in through a hole while the bag was in my kitchen. I'm in Texas, if that matters.

Insects in the malt bag

  • Not a great picture of them, going to make identification hard. Also probably not the right place for this question. I'm not sure such a site exists on the network

    The one on the left looks like the lesser of two weevils.

  • If you milled in store before leaving I'd wager they infiltrated once you got home

  • While it might be hard to ID from that picture, biology.stackexchange.com has a tag specifically for species identification

They're possibly weevils. The one in the middle looks like it has a long 'snout' that weevils tend to have.

    Yes "insects in grain or flour" are usually weevils in my experience - including here in Texas. Had a bee in my wort yesterday but I think it flew in (at flame out and about to sieve into the fermentation barrel).

    Not just possibly. Those are undoubtedly weevils, almost definitely grain weevils. Oct 16, 2017 at 16:01

    There may be a way to test the hypothesis that these are weevils. Put one of them on a surface like a table, and give it a nudge. Apparently, weevils wobble, but they don't fall down!
