My beloved coffee has become bitter, traced the problem to my ibriks ( jezve / cesve ) .... Never really thought about it, but I probably have close to 100 batches on the 3 cup ( Espresso size " cups " ) and maybe 70 on the single cup, which also shows signs of detinning...This is , of course , normal.... Anyone know where I can get them retinned at a reasonable price ?? ...The alternative is to toss them in the recycling bin and invest in a pure silver lined pot, which comes with free resilvering service once per year : C2 Cezve / Turkish Coffee Pot - https://soy-turkiye.myshopify.com/products/cezve-turkish-coffee-pot-soy-c2-serves-2?variant=28262291723
