So people in the NYC area can’t just go without beer until Shavuos? I like beer too, but I can certainly live without it for a few weeks. As noted above, “… that this is a machlokes haposkim with recognized poskim on both sides of the issue and one should consult his own Rav what to do. ” So consult your posek, and if the prospect of going without beer next year is too distressing, buy enough and sell it with the chometz (unless you’re one of those who doesn’t sell real chometz, in which case I advise you to switch to wine.)
It’s a good thing that the possibility of a sheilah has been recognized, but it’s nothing to get very excited about. Just follow your Rav.
