This latest wheat strain is the perfect partner for Herr Weizen. Balancing fenols and esters perfectly, the tipical banana and chewing gum marks are left behind. Therefore, nutmeg and clove can show their smell as well. This strain is really sensitive to cell number, underfeeding is recommended for fenol tastes.

One of the best choice for NEIPA. During fermentation due to the high poly-fenol creation and low deconstruction of protein, you can easily get peary or peachy signs in your beer. Due to the high fermentation profile you can make drier beers with him. Strong ester creation, perfect NEIPA taste with fruity marks.

YF-104 - Terrier
Yorkshire style ale
A dog bred for herding, he’s an instinctive shepherd who will always keep the flavours in check. Although also from the island it is hard to confuse with a bulldog type. Prefers caramel brown fields, the fresh scent of which he is carrying.
This Yorkshire yeast is a special type of English yeast that ferments in a bit more caramelised way than most others and while still generating esters during fermentation these are completely different than those of English yeasts. That’s what makes it a special and popular type of yeast. Settles well.

YF 103 - Steamprunk
London style ale
A mysterious shadow in London’s mist, approaching it is not for the faint-hearted! His personality is a blend of the rebelliousness of a punk and the elegance of a gentleman. His bittersweet appearance may well get out of our sight, but will never leave our mind.
This strain has an exceptional harmony of malt and hop profiles making it a perfect choice for a New England IPA. The yeast is able to transform the geraniol content in the hops into terpenes during fermentation creating tastefully strong fruity esters.

YF 102 - British bulldog
Ringwood style ale
The Gentleman’s companion – no true Brit can exist without it. He rewards your hospitality with loyalty and warmth. An obedient one, who will always follow orders dutifully.
One of the best English yeasts with a high temperature profile. Does not require straining, settles well allowing it to yield a higher sugar content returning a sweet malty taste. Generates high levels of diacetyl. Highly recommended for most English ales.

YF 101 - Queen of hearts
British style ale
A true English dame, one of London’s most prestigious. Usually reserved, but anyone se touches will instantly feel the fire and passion within. Not the one for discretion, she’s a whirlwind of gossip but has other qualities to make up for that.
A yeast similar to British Bulldog, but settles harder enabling it to ferment a dryer brew. In return it generates less diacetyl. Its ester profile is similar to that of its bulldog sibling, making it an excellent choice for English bitter beers.
