Hello,
1) You may try to set min-heiht or the product title .content-product .product-title a {min-height: 70px;} 2) Because some of your original images still have the different size, for example https://www.vinopura.nl/wp-content/uploads/2017/11/202002-2.png https://www.vinopura.nl/wp-content/uploads/2017/11/202007-3.png etc I have changed the WC image settings. Check the products grid now.
.content-product .product-title a {min-height: 70px;}
Regards
